How to Keep a Drafty Apartment Warm Without Turning Up the Heat

 A drafty apartment can feel cold even when the heat is running.

Cold air may be sneaking in around a window, a gap under the front door may be letting in a steady draft, or one room may simply feel much colder than the rest of the apartment.

Turning up the thermostat can help, but it doesn't solve the underlying problem. If warm air is escaping and cold air is getting in, you may just end up running the heat longer.

The good news is that renters still have options. Start by finding where the cold air is coming from, then use simple, reversible fixes to make the apartment feel warmer.

Warm living room in a drafty apartment

1. Find the Draft Before You Try to Fix It

Don't start by buying thermal curtains, window film, and draft stoppers for the entire apartment.

First, figure out where the cold spots actually are.

On a cold or windy day, slowly move your hand around the edges of windows and exterior doors. Pay attention to window frames, the bottom of doors, and anywhere you can visibly see a gap.

ENERGY STAR notes that noticeable drafts, rattling windows, and visible gaps around window or door trim can be signs of air leakage.

You may discover that one window is responsible for much of the discomfort.

That's useful because you can fix the biggest problem first instead of trying to warm the entire apartment.

2. Stop Cold Air Coming Through the Windows

Windows are one of the first places to investigate in a drafty apartment.

If you can feel cold air around the frame, check whether the window is fully closed and locked. A window that looks closed may not be sealing tightly.

For gaps around movable parts of a window, removable weatherstripping may help if your lease allows it. The U.S. Department of Energy specifically recommends weatherstripping around windows and doors as one way renters can reduce air leaks.

If the entire window feels like a source of cold, a temporary interior window-film kit is another option worth considering.

ENERGY STAR describes shrink-to-fit plastic window coverings as an inexpensive way to reduce drafts and help rooms feel warmer during winter.

Just remember that rental rules vary. Avoid permanent modifications unless you have permission from your landlord or property manager.

3. Block the Gap Under a Drafty Door

Sometimes the problem is much easier to see.

If there's a noticeable gap under your apartment door, cold air from an exterior hallway, stairwell, or outdoors may enter underneath it.

A draft stopper is one of the simplest renter-friendly solutions.

Place it along the bottom of the door when it's closed. There are commercial versions available, but the important part is simply creating a barrier against the moving air.

DOE includes draft stoppers among its suggestions for renters dealing with air leakage around doors.

If there is a large permanent gap, damaged weatherstripping, or a door that doesn't close properly, report it to your landlord rather than trying to rebuild or permanently alter the door yourself.

4. Use Your Curtains Differently During the Day and Night

Curtains can do more than provide privacy.

On sunny winter days, open curtains or blinds on windows receiving direct sunlight. The sun can provide some free warmth.

Once the sun goes down, close them again.

ENERGY STAR recommends opening drapes during daylight hours in cold weather to take advantage of the sun's warmth. DOE guidance also recommends window coverings to help retain warmth during winter.

Thicker curtains can also make the area near a cold window feel more comfortable.

But there's an important detail: don't let curtains block heating vents, radiators, or other heat sources.

You want to reduce the effect of the cold window without trapping the heat where it can't circulate through the room.

5. Make Cold Floors More Comfortable

Sometimes your apartment isn't especially drafty at eye level, but the floor makes the whole room feel cold.

This is particularly noticeable with tile, laminate, hardwood, or floors above unheated spaces.

A rug won't repair missing insulation underneath the building, but it can make the room much more comfortable to walk and sit in.

Focus on the places where you actually spend time: beside the bed, under your desk, near the couch, or in the main living area.

You don't necessarily need wall-to-wall coverage.

The goal is comfort, not rebuilding the apartment.

6. Don't Accidentally Block the Heat You Already Have

Before trying to create more warmth, make sure you're not preventing your existing heating system from doing its job.

Look around the room.

Is a couch sitting directly in front of a heating vent? Is a long curtain covering a radiator? Is furniture blocking a return vent?

If so, rearranging the room may help warm air circulate more effectively.

If your system has an accessible air filter that tenants are responsible for maintaining, check the lease or manufacturer's instructions to see whether it needs cleaning or replacement. DOE includes regular filter maintenance among its renter energy-efficiency recommendations because proper airflow matters for heating and cooling performance.

Don't open, modify, or attempt to repair heating equipment yourself.

If the heating system isn't working properly, that's a maintenance issue.

7. Warm the Space You're Actually Using

If you're spending the evening in the living room, it doesn't make much sense to focus your comfort efforts on an unused bedroom.

Close exterior doors and obvious sources of drafts, use rugs where you spend time, close curtains after sunset, and arrange the room so you're not sitting directly beside the coldest window.

Even moving your desk or favorite chair away from a cold exterior wall or inefficient window can make a noticeable difference in comfort.

ENERGY STAR points out that cold interior window surfaces themselves can make a person sitting nearby feel chilly, even when the room's thermostat reading seems reasonable.

That's an important distinction.

Sometimes the solution isn't making the entire apartment hotter. It's making the part of the apartment you're using more comfortable.

8. Pay Attention to Uneven Temperatures

One cold room doesn't necessarily mean you need a higher thermostat setting.

If the living room feels comfortable but the bedroom is consistently freezing, investigate why.

Check for:

• a particularly drafty window
• damaged seals around an exterior door
• blocked heating vents
• a vent that doesn't appear to be working
• unusually cold exterior walls or floors

ENERGY STAR lists drafts and uneven hot or cold rooms among signs that a home's performance may need attention.

If basic renter-friendly fixes don't help, document the problem and contact your landlord or property manager.

9. Know When a Draft Is a Maintenance Problem

Not every cold apartment can—or should—be fixed with curtains and weatherstripping.

A renter-friendly fix makes sense for a small draft. It doesn't make sense for a window that won't close, damaged frames, major gaps, a malfunctioning heating system, or persistent indoor temperatures that may violate local housing requirements.

Take photos of visible damage and note where and when the problem occurs.

Then report it through whatever maintenance process your building uses.

This is especially important if you notice moisture problems around windows. Condensation can have several causes, and ENERGY STAR recommends managing indoor humidity and maintaining appropriate ventilation rather than simply sealing everything indiscriminately.

Air sealing can also affect indoor air quality and combustion safety in some homes, so substantial sealing work belongs with the property owner or a qualified professional rather than becoming an improvised renter DIY project.

What Should You Try First?

If your apartment feels cold, don't tackle everything at once.

Start with this order:

1. Find the coldest window or door.
2. Block obvious drafts with renter-safe methods.
3. Open curtains for useful sunlight and close them after dark.
4. Make sure furniture and curtains aren't blocking your heat.
5. Use rugs and room layout to improve comfort where you spend the most time.
6. Report structural or heating problems that simple fixes can't solve.

This approach is usually more useful than immediately raising the thermostat because you're addressing the places where comfort is being lost.

FAQ

Why is my apartment cold even when the heat is on?

Drafts, cold window surfaces, blocked vents, uneven heating, or problems with the building envelope can all make an apartment feel colder than the thermostat suggests. Start by checking windows and exterior doors and making sure heating vents aren't blocked.

How can I stop cold air from coming through apartment windows?

If your lease permits it, removable weatherstripping can help with air leaks around movable window parts. Temporary interior window film can also reduce drafts. If the window is damaged or won't close properly, report it to your landlord rather than trying to make a permanent repair yourself.

Do thermal curtains really help a cold apartment?

Window coverings can help retain warmth and reduce discomfort near cold windows. Open them when useful winter sunlight is coming through, then close them after sunset.

How can I make my apartment warmer without spending much money?

Start with the free fixes: identify the draft, fully close and lock windows, move furniture away from heating vents, use sunlight during the day, and close curtains at night. Then consider inexpensive renter-friendly options such as a door draft stopper, removable weatherstripping, or temporary window film where appropriate.

Should I tell my landlord if my apartment is very drafty?

Yes, particularly if windows or doors are damaged, won't close properly, have significant gaps, or the heating system isn't maintaining adequate warmth. Small comfort improvements are one thing; building and heating-system defects are different.

Final Thoughts

A drafty apartment doesn't always need more heat. Sometimes it needs fewer places for warmth to escape and fewer cold spots around the areas where you actually live.

Start with the worst window or door, use reversible renter-friendly fixes where appropriate, take advantage of sunlight during the day, and keep your existing heat from being blocked.

And if the problem is bigger than a minor draft, involve your landlord rather than trying to turn a building problem into a DIY project.

How to Lower Your Heating Bill in an Apartment: 11 Renter-Friendly Ways

 

Apartment heating

Winter can make an apartment feel expensive fast. You may not be able to replace the windows, add insulation, or upgrade the heating system, but that doesn't mean your heating bill is completely out of your control.

The best approach is to focus on three things: keeping warm air from escaping, heating your apartment only as much as necessary, and fixing small sources of energy waste.

Here are 11 renter-friendly ways to lower your heating bill without taking on a major home improvement project.

1. Adjust Your Thermostat Before Buying Anything

Start with the thermostat because it can make a meaningful difference without costing you anything.

The U.S. Department of Energy recommends keeping your home at a temperature that feels comfortable when you're awake and setting it lower when you're asleep or away. According to the DOE, turning the thermostat back 7°F to 10°F for eight hours a day can save as much as 10% a year on heating and cooling.

You don't have to make your apartment uncomfortable. Try a small adjustment first and see how it feels.

If you have a programmable or smart thermostat, create a schedule around when you normally leave, return home, and go to bed.

One important exception is a heat pump. Large temperature setbacks aren't always the most efficient strategy for every heat-pump system, particularly when recovering from the setback activates electric auxiliary heat. If your apartment uses a heat pump, check the thermostat or system guidance before making aggressive changes.

2. Find the Drafts Before You Try to Fix Them

A cold apartment isn't always cold because the heating system is weak. Sometimes the problem is warm air escaping through gaps around windows and doors.

Drafty window

On a cold or windy day, check around:

• window frames
• exterior doors
• balcony or patio doors
• gaps around pipes and utility openings
• window air-conditioning units that remain installed during winter

If you can feel cold air entering around one of these areas, you've found a place worth investigating.

For a renter, the goal isn't to permanently modify the building. It's to identify obvious leaks and use an appropriate temporary solution or ask the landlord to repair the problem.

3. Use Removable Weatherstripping Where Your Lease Allows It

Weatherstripping can help reduce air leakage around movable parts of doors and windows. A draft stopper can also help with a noticeable gap beneath a door.

Before applying adhesive products, check your lease and make sure the material can be removed without damaging paint, wood, or window frames.

If a gap appears to be caused by a damaged window, poorly fitting exterior door, or another building defect, report it to your landlord rather than trying to make a permanent repair yourself.

4. Use Curtains and Blinds Strategically

Your curtains can do more than provide privacy.

On sunny winter days, open curtains or blinds on windows receiving direct sunlight and let the sun provide some free warmth. Close them again after sunset to reduce the discomfort you feel near cold windows.

The U.S. Department of Energy specifically recommends opening curtains on south-facing windows during winter days to take advantage of sunlight and closing them at night.

Just make sure curtains don't block radiators, baseboard heaters, or heating vents. Blocking the source of heat can make it harder to warm the room effectively.

5. Keep Heating Vents and Radiators Clear

Before increasing the thermostat, look at where the heat is actually going.

A sofa in front of a vent, long curtains covering a radiator, or furniture pressed against a baseboard heater can interfere with heat distribution.

Give heating equipment enough open space to work as intended.

If your apartment has a forced-air system and you're responsible for the filter, check the manufacturer's instructions and your lease or building rules before replacing it. A dirty filter can restrict airflow and make a heating and cooling system work harder.

If building management handles the system, ask them about maintenance rather than opening or modifying equipment yourself.

6. Use a Ceiling Fan Correctly in Winter

A ceiling fan isn't only for summer.

Warm air naturally rises, which can leave the upper part of a room warmer than the space where you're sitting. Many ceiling fans have a winter setting that runs the blades slowly in the reverse direction to help circulate warm air.

The correct direction depends on the fan's design, so check its instructions rather than assuming every model works exactly the same way.

Keep the speed low. The goal is to redistribute warm air, not create a chilly breeze.

7. Heat Yourself Before You Heat the Entire Apartment More

If you're slightly chilly, turning up the thermostat isn't your only option.

Warm socks, slippers, a sweater, and an extra blanket can make a lower indoor temperature feel much more comfortable. Rugs can also make tile, laminate, and hardwood floors feel less cold underfoot.

This doesn't mean you should tolerate an unsafe or unreasonably cold apartment. It simply means that improving personal comfort can sometimes prevent unnecessary thermostat increases.

8. Don't Ignore Hot-Water Use

Your winter utility costs aren't only about space heating.

Hot water also requires energy, so long hot showers can add to your overall utility costs. Simple habits such as taking slightly shorter showers and washing appropriate laundry loads in cold water can reduce the amount of energy used to heat water.

If your landlord pays for hot water, this may not change your personal bill directly. Check which utilities you're actually responsible for before deciding where to focus your effort.

9. Cut Small Sources of Electricity Waste Too

Reducing your heating bill doesn't help much if other winter electricity use quietly increases.

More time indoors often means more lighting, television, computers, gaming devices, and other electronics. Turn off equipment you aren't using and use sleep or energy-saving modes when they're available.

Power strips can make it easier to shut down several devices together, but don't obsess over unplugging every tiny charger in your home. Start with the devices you use frequently or groups of electronics that remain powered for long periods.

The biggest savings usually come from fixing the biggest sources of energy use first.

10. Be Careful With Space Heaters

A space heater can make one room feel warmer, but it isn't automatically a cheaper substitute for your apartment's main heating system. The result depends on your heating system, electricity price, room size, insulation, and how long you use the heater.

Safety matters even more than potential savings.

The U.S. Consumer Product Safety Commission recommends keeping portable heaters at least three feet away from combustible materials such as curtains, bedding, and furniture. Electric space heaters should be plugged directly into a wall outlet rather than an extension cord or power strip, and they should be turned off when you're sleeping.

Never use an oven or stovetop to heat your apartment.

11. Know When the Problem Belongs to the Landlord

Some heating problems can't be solved with curtains and weatherstripping.

Contact your landlord or property manager if you notice problems such as a window that won't close properly, a damaged exterior door, a heating system that isn't working correctly, or severe drafts that appear to come from building defects.

Document the problem with photos and a written message when appropriate.

Rental heating requirements vary by location, so avoid assuming that a particular minimum temperature or repair deadline applies everywhere. If the problem isn't resolved, check the tenant rules or housing authority information for your city or state.

What Should You Do First?

If you want to lower your heating costs without turning your apartment into a weekend project, start with the easiest high-impact actions.

First, review your thermostat habits. Then check windows and doors for obvious drafts, use curtains strategically, and make sure furniture isn't blocking your heat.

After that, look at hot-water use and everyday electricity habits.

This order matters because saving money isn't about collecting dozens of tiny hacks. It's about finding where your apartment is wasting the most energy and dealing with those problems first.

A Simple Apartment Winter Checklist

Before colder weather arrives:

• Test your heating system before you urgently need it.
• Check windows and exterior doors for drafts.
• Ask your landlord about damaged seals or windows.
• Review your thermostat schedule.
• Move furniture away from heating vents and radiators.
• Check whether curtains are blocking heat.
• Reverse your ceiling fan if the model has a winter setting.
• Identify which utilities you actually pay for.
• Check smoke and carbon monoxide alarms as appropriate for your home.
• Review space-heater safety before using one.

Doing these things before the first truly cold week gives you time to solve problems without waiting for an unexpectedly high utility bill.

Frequently Asked Questions

What temperature should I keep my apartment in winter?

There isn't one perfect temperature for every household. The U.S. Department of Energy recommends setting the thermostat as low as is comfortable when you're home and awake, then considering a lower setting while you're asleep or away. Comfort, health needs, pets, children, your heating system, and the risk of frozen pipes can all affect the right setting.

Does lowering the thermostat really save money?

Generally, yes. The Department of Energy says setting the thermostat back 7°F to 10°F for eight hours a day can save as much as 10% per year on heating and cooling. However, the best strategy can differ for some heat-pump systems.

How can I insulate apartment windows without replacing them?

Depending on your lease, renter-friendly options may include removable weatherstripping, temporary window film, draft-reducing window coverings, and curtains. If the window itself is damaged or doesn't close properly, contact the landlord instead of trying to make a permanent repair.

Is a space heater cheaper than central heat?

Not necessarily. A space heater may make sense for temporarily warming a small occupied area, but whether it saves money depends on the main heating system, local energy prices, room size, insulation, and usage time. Don't assume a portable electric heater is automatically cheaper.

What if I don't control the thermostat in my apartment?

Focus on the things you can control: drafts, curtains, furniture placement, hot-water use, and electricity habits. If your apartment is consistently too hot or too cold, document the temperature and contact your landlord or building manager. Local rental-housing rules may also apply.

Final Thoughts

Lowering your winter heating bill as a renter isn't about making expensive upgrades to a home you don't own.

Start with the thermostat, stop obvious drafts, make better use of sunlight and window coverings, keep heating equipment unobstructed, and pay attention to hot water and electricity use.

Most importantly, separate problems you can fix from problems the property owner needs to address.

A few sensible changes made before cold weather arrives can make your apartment more comfortable while giving you better control over winter utility costs.

How to Reheat Fries in an Air Fryer So They’re Crispy Again

 

Crispy fries reheated in an air fryer

Leftover fries can go from crispy to soft surprisingly fast. Refrigeration makes the problem even more noticeable, and reheating them in the microwave usually gives you hot fries that are still limp.

An air fryer is one of the easiest ways to bring back some of that crisp texture.

For most regular French fries, start at 375°F (190°C) for about 3 to 5 minutes, shaking the basket halfway through. Thin fries may need less time, while thick-cut fries and potato wedges usually need longer.

The key is to avoid overcrowding the basket and check the fries early so they don’t dry out.

Best Temperature for Reheating Fries in an Air Fryer

For regular French fries, 375°F (190°C) is a practical starting temperature.

It is hot enough to crisp the outside quickly without requiring a long reheating time.

Air fryer fries reheating time and temperature guide

A good starting point is:

Shoestring or very thin fries: 375°F for 2–3 minutes

Regular French fries: 375°F for 3–5 minutes

Crinkle-cut fries: 375°F for 4–5 minutes

Steak fries: 375°F for 4–6 minutes

Potato wedges: 375°F for 5–7 minutes

Sweet potato fries: 350°F for 3–5 minutes

These are starting times, not exact rules. Air fryers vary, and the amount of food, thickness of the fries, and how cold they are can all affect reheating time.

[Insert the Air Fryer Reheating Guide for Fries infographic here]

Check the fries before the suggested time is up. If they need more cooking, add another 30 to 60 seconds rather than several extra minutes at once.

How to Reheat Fries in an Air Fryer

1. Set the air fryer to 375°F

Set your air fryer to 375°F (190°C).

If your model normally requires preheating, let it heat before adding the fries. Some air fryers heat quickly enough that a separate preheating period may not be necessary, so follow the instructions for your appliance.

2. Put the fries in the basket

Arrange the fries loosely in the air fryer basket.

Fries loosely arranged in an air fryer basket

You do not need every fry perfectly separated, but avoid filling the basket with a thick pile.

Air fryers work by circulating hot air around the food. When fries are packed too tightly together, moisture can become trapped and make it harder for the surface to crisp.

If you have a large amount of fries, reheating them in two batches usually works better.

3. Air fry for 3 to 5 minutes

Reheat regular fries for about 3 to 5 minutes.

Shake the basket about halfway through.

This moves the fries around and gives more of their surface exposure to the hot circulating air.

Thin fries can be ready in only a few minutes. Thick fries may need an extra minute or two.

4. Check them early

Do not rely entirely on the timer.

Take out one fry and check whether the center is hot and the outside is crisp enough for you.

If the fries still seem soft, cook them for another 30 to 60 seconds and check again.

This is better than automatically adding several minutes because fries can become dry and hard quickly.

5. Serve immediately

Once the fries are hot and crisp, take them out and serve them right away.

Reheated fries will gradually soften again as they sit.

Taste before adding more salt, especially if you are reheating restaurant or fast-food fries that were already heavily seasoned.

Do You Need Oil to Reheat Fries?

Usually, no.

Most restaurant and fast-food fries already have oil on their surface, so adding more oil is rarely necessary.

Putting extra oil on them can sometimes make the fries feel greasy rather than crisp.

Dry homemade fries are slightly different. If they seem unusually dry, a very light coating of oil may help, but start with as little as possible.

For most leftover fries, try reheating them without any additional oil first.

Why Do Fries Get Soggy After Refrigeration?

Fresh fries have a crisp outer layer and a softer interior.

After they cool, moisture inside the potato gradually redistributes. That moisture can soften the outside of the fry.

Refrigeration does not improve the texture.

The goal when reheating fries is therefore not simply to make them hot again. You also want to remove some surface moisture.

That is where the air fryer helps.

Hot circulating air heats the fries while drying the outside, which can restore some of their original crispness.

Why Are My Air-Fried Fries Still Soggy?

If your reheated fries are hot but still soft, one of these problems is usually responsible.

The basket is overcrowded

This is one of the most common causes.

A large pile of fries prevents hot air from reaching enough of their surface.

Try reheating a smaller batch instead.

The temperature is too low

If the air fryer is not hot enough, the fries can warm gradually without crisping properly.

For regular French fries, 375°F is a useful starting point.

You didn’t shake the basket

Fries sitting in the same position for the entire cooking time may heat unevenly.

Shake the basket halfway through reheating so different sides are exposed to circulating air.

The fries are wet

Condensation can sometimes form on refrigerated food.

If the fries look noticeably damp when you take them out of the refrigerator, gently blot excess moisture before putting them in the air fryer.

You added too much oil

More oil does not automatically mean crispier fries.

Restaurant fries generally already contain plenty of oil. Adding more can make the surface heavy or greasy.

How to Reheat Fast-Food Fries in an Air Fryer

Thin fast-food fries usually reheat faster than thicker fries.

Start at 375°F for about 2 to 3 minutes.

Shake the basket, then check the fries.

If they are not hot and crisp enough, continue in short 30- to 60-second intervals.

Avoid automatically cooking thin fries for five minutes or longer. They can quickly become dry or hard.

How to Reheat Thick-Cut Fries

Steak fries and other thick-cut fries need more time because there is more potato in the center.

Start at 375°F for about 4 to 6 minutes.

Shake or turn them halfway through.

If the outside is becoming too brown before the center is fully heated, reduce the temperature slightly and continue reheating.

How to Reheat Potato Wedges

Potato wedges are thicker than standard fries, so expect them to take longer.

Start with 375°F for about 5 to 7 minutes.

Turn or shake them halfway through the cooking time.

Very large wedges may need additional time.

Again, use the time as a starting point rather than a guarantee.

How to Reheat Sweet Potato Fries

Sweet potato fries can brown quickly, so it helps to use a slightly lower temperature.

Start at about 350°F (175°C) for 3 to 5 minutes.

Shake the basket halfway through and check them early.

If they need more time, continue in short intervals.

Should You Reheat Fries in the Microwave?

You can, but the texture is different.

A microwave is good at heating food quickly, but it does not dry the exterior of fries the same way an air fryer does.

That is why microwaved fries can become hot while remaining soft.

In a comparison by The Kitchn, air-fried leftover fries were reheated at 350°F for roughly 3 to 5 minutes and performed especially well for restoring a crisp exterior.

If crispness is the priority, the air fryer is usually the better choice.

Air Fryer vs. Oven for Reheating Fries

Both can work.

An air fryer is especially convenient for a small portion because you can reheat the fries quickly without heating a full-size oven.

An oven can be more practical when you have a large amount.

If the fries would require several air-fryer batches, spreading them across a baking sheet in the oven may save time overall.

For a small serving, use the air fryer.

For a large batch, consider the oven.

How Long Can You Keep Leftover Fries?

Storage matters just as much as reheating.

USDA guidance says restaurant and home-cooked leftovers should generally be refrigerated within two hours and used within three to four days.

USDA also recommends reheating leftovers to 165°F (74°C) when food safety is a concern.

If fries or other perishable leftovers have been sitting at room temperature for more than two hours, reheating them does not automatically make them safe again.

When in doubt about how long food has been left out, it is safer to discard it.

Common Mistakes When Reheating Fries

The most common mistake is filling the air fryer basket too full.

You should also avoid adding unnecessary oil, using the same cooking time for every type of fry, and leaving thin fries unattended for too long.

Remember that you are reheating already-cooked potatoes, not cooking raw fries from scratch.

The goal is simply to warm the center and restore the exterior texture.

Frequently Asked Questions

What temperature should I use to reheat fries in an air fryer?

Start at 375°F (190°C) for most regular French fries.

Sweet potato fries can be reheated at a slightly lower temperature, around 350°F.

How long do fries take to reheat in an air fryer?

Most regular fries take about 3 to 5 minutes.

Thin fries may take only 2 to 3 minutes, while thick fries and potato wedges may need 5 minutes or more.

Should I add oil to leftover fries?

Usually not.

Restaurant and fast-food fries already contain oil, so additional oil is rarely necessary.

Should fries be in a single layer?

A perfectly single layer is not always essential, but the fries should be loose enough for air to circulate around them.

Avoid packing the basket with a thick pile.

Why do my fries turn hard in the air fryer?

They were probably reheated for too long.

Check thin fries after only a couple of minutes and add extra cooking time in short intervals.

Final Thoughts

For most leftover fries, start with 375°F for 3 to 5 minutes and shake the basket halfway through.

Use less time for thin fries and more time for thick fries or potato wedges.

You usually do not need extra oil, and you will get better results if you avoid overcrowding the basket.

Most importantly, check the fries early. A short extra burst of cooking can make them crispier, but several unnecessary minutes can turn them dry and hard.

How to Reheat Pizza in an Air Fryer Without Drying It Out

Pizza slices reheating in an air fryer

Leftover pizza can still taste great the next day, but reheating it can be tricky. A microwave gets the job done quickly, but the crust often turns soft or chewy. A conventional oven can restore some crispness, but heating a full oven for one or two slices isn't always worth it.

An air fryer is a convenient alternative. It can make the bottom of the crust crisp again while warming the cheese and toppings in just a few minutes.

The key is using moderate heat and checking the pizza early. Too much heat or too much time can turn a crispy slice into a dry one.

The Quick Answer

To reheat pizza in an air fryer, place the slices in a single layer and heat them at 350°F (175°C) for about 3 to 5 minutes.

Start checking after about 3 minutes. Thin-crust pizza may be ready sooner, while thick or heavily topped slices may need an extra minute or two.

For thicker pizza, you can also lower the temperature slightly to around 325°F (165°C) and give it more time. This helps the center warm up without making the crust too hard.

Air fryers vary, so use these times as a starting point rather than a strict rule.

How to Reheat Pizza in an Air Fryer

Reheating pizza in an air fryer is simple, but how you arrange and heat the slices can make a noticeable difference.

1. Place the Pizza in a Single Layer

Take the leftover pizza out of the refrigerator and arrange the slices flat in the air fryer basket.

Don't stack the slices or overlap them. Hot air needs to circulate around the pizza for the crust to crisp properly.

If your air fryer is small, reheating two batches is usually better than squeezing too many slices into the basket.

2. Set the Temperature to 350°F

Set your air fryer to 350°F (175°C).

This is a good starting temperature for most refrigerated pizza because it's hot enough to crisp the crust without immediately drying out the cheese and toppings.

If you're reheating a very thick slice or pizza with a lot of toppings, try 325°F (165°C) instead.

3. Heat the Pizza for 3 to 5 Minutes

Cook the pizza for about 3 minutes, then check it.

Look for melted, hot cheese and a crust that feels crisp underneath. If the middle is still cool, continue heating in 30-second to 1-minute intervals.

Thin-crust pizza can sometimes be ready in only 2 to 3 minutes. Regular pizza often takes around 3 to 5 minutes, while thick-crust or heavily topped slices may need 4 to 6 minutes.

Checking early matters because pizza can go from perfectly crisp to dry surprisingly quickly in an air fryer.

4. Remove and Let It Rest Briefly

Once the pizza is hot and the crust is crisp, remove it from the basket.

Let it sit for a minute before eating. The cheese and toppings can be much hotter than they look, especially on thicker slices.

What Temperature Is Best for Reheating Pizza?

For most leftover pizza, 350°F (175°C) is a reliable place to start.

You don't need extremely high heat to get a crispy crust. In fact, turning the air fryer up too high can cause the edges and cheese to dry out before the center of the slice is properly heated.

For thin-crust pizza, try 350°F for about 2 to 4 minutes.

For regular pizza, start with 350°F for about 3 to 5 minutes.

For thick-crust pizza, try 325°F to 350°F for about 4 to 6 minutes.

Pizza covered with lots of meat, vegetables, or extra cheese may also benefit from slightly lower heat and a little more cooking time.

These times aren't exact because air fryer size, heating power, pizza thickness, and the amount of toppings all affect how quickly a slice reheats.

For your first batch, check sooner rather than later. Once you know how your particular air fryer handles leftover pizza, adjusting the next batch is easy.

Do You Need to Preheat the Air Fryer?

Not always.

For just one or two slices of leftover pizza, many air fryers can reheat the food effectively without a separate preheating step.

However, air fryer designs vary. Some models recommend preheating, and starting with a hot basket can also make the first batch cook a little faster.

If you preheat your air fryer, check the pizza earlier because it may be ready sooner than the suggested time.

When in doubt, follow the instructions for your specific air fryer model.

How to Reheat Pizza Without Drying It Out

Crispy reheated pizza from an air fryer

The biggest mistake is using too much heat.

It can be tempting to turn the temperature up because you want the crust crispy, but very high heat can dry out the exposed crust and toppings before the whole slice is warm.

Instead, stick with moderate heat and check the pizza frequently.

Also, don't leave the pizza in the air fryer simply because a recipe says to cook it for a certain number of minutes. If the cheese is hot and the crust is already crisp, take it out.

You're reheating an already-cooked slice, not cooking a pizza from scratch.

Thick pizza deserves extra attention. Lowering the temperature slightly and extending the heating time can help warm the center without overcooking the outside.

Why Is My Reheated Pizza Soggy?

If the pizza comes out hot but the bottom is still soft, excess moisture or poor airflow may be the problem.

Pizza naturally contains moisture from the sauce, cheese, vegetables, and other toppings. During refrigeration, some of that moisture can move into the crust.

The air fryer needs enough airflow to remove some of that surface moisture and crisp the crust again.

Avoid stacking slices or packing the basket too tightly. Give each slice enough space for hot air to circulate.

If you're having the same problem with fries, chicken, or other foods, our guide Why Is My Air Fryer Food Soggy? 7 Ways to Make It Crispy explains the most common causes of soggy air-fried food.

Can You Put Aluminum Foil Under Pizza in an Air Fryer?

You usually don't need aluminum foil to reheat pizza.

Placing the pizza directly in the basket allows hot air to circulate around the crust, which can help it become crisp.

If you want to use foil for easier cleanup, make sure it doesn't block too much airflow and that your air fryer's manufacturer allows it.

Loose foil can also be a problem in an air fryer because the circulating air may move it toward the heating element. It should be properly secured by food and never placed loosely in an empty air fryer.

Air Fryer vs. Microwave: Which Is Better for Reheating Pizza?

Both methods work, but they produce different results.

A microwave is the fastest option. If you just want a hot slice and don't care much about the texture of the crust, it may be all you need.

The downside is that microwaved pizza often has a softer crust. Microwave heating doesn't create the same dry, circulating heat that helps an air fryer crisp the surface.

An air fryer takes a few minutes longer but generally does a better job of restoring a crisp bottom while keeping the cheese hot.

For one or two leftover slices, it also avoids the time and energy involved in heating a full-size oven.

If speed matters most, use the microwave. If you want a crispier crust, the air fryer is usually the better choice.

Can You Reheat Frozen Pizza Slices in an Air Fryer?

Yes. If you've frozen leftover pizza, you can reheat individual slices in an air fryer without necessarily thawing them first.

Frozen pizza will take longer than refrigerated pizza, so start at a moderate temperature and check the center before eating.

Avoid using very high heat just to speed things up. The outside can become overly crisp while the center remains cold.

Because frozen slices can vary considerably in thickness and toppings, use appearance and temperature rather than relying only on a fixed cooking time.

Common Mistakes to Avoid

Using too high a temperature: Higher heat isn't always better. It can make the crust hard and dry out the cheese before the center is warm.

Overcrowding the basket: Overlapping slices restrict airflow and can leave parts of the crust soft.

Walking away until the timer ends: Air fryers heat quickly. Check the pizza early, especially when reheating thin slices.

Using the same time for every pizza: A thin cheese slice and a thick, heavily topped slice won't reheat at the same speed.

Reheating for too long: Once the pizza is hot and the crust has reached the texture you want, remove it. Extra time usually doesn't improve it.

Frequently Asked Questions

How long should you reheat pizza in an air fryer?

Most refrigerated pizza takes about 3 to 5 minutes at 350°F (175°C). Thin slices may be ready sooner, while thick or heavily topped pizza can take longer. Check the pizza early because air fryer performance varies by model.

What temperature should I use to reheat pizza?

Start at 350°F (175°C) for most pizza. For particularly thick slices, reducing the temperature to around 325°F (165°C) can give the center more time to heat without making the outside too dry.

Can you put cold pizza straight into an air fryer?

Yes. Refrigerated leftover pizza can go directly into the air fryer. Arrange the slices in a single layer and leave enough room for air to circulate.

Can I reheat several slices at once?

Yes, as long as the slices fit in a single layer without significant overlap. If they don't, reheat them in batches. Crowding the basket can lead to uneven heating and a softer crust.

Why does my pizza get hard in the air fryer?

The most likely causes are too much heat or too much cooking time. Try lowering the temperature slightly or checking the pizza earlier during the next batch.

Final Thoughts

Reheating pizza in an air fryer doesn't require much effort. For most refrigerated slices, 350°F (175°C) for about 3 to 5 minutes is a good starting point.

Keep the slices in a single layer, avoid excessive heat, and start checking before you think they're finished. Thin pizza may need only a few minutes, while thick or heavily topped slices may benefit from slightly lower heat and more time.

The goal is simple: get the center hot while bringing back a crisp crust without drying out the cheese and toppings.

Can You Put Aluminum Foil in an Air Fryer?

Aluminum foil inside an air fryer basket

 Yes, you can use aluminum foil in many air fryers, but not every manufacturer recommends it.

The most important rule is to check the instructions for your specific air fryer before using foil. Some manufacturers all
ow aluminum foil when it is used correctly, while others recommend avoiding it altogether.

If your air fryer does allow foil, placement matters. Covering too much of the basket can restrict the hot air that makes an air fryer work efficiently.

Here’s what you need to know before putting aluminum foil in your air fryer.

Is Aluminum Foil Safe in an Air Fryer?

Aluminum foil can be safe in many air fryers when the manufacturer allows it and you use it properly.

For example, COSORI says aluminum foil can generally be used in its air fryers, but it should not block airflow or cover the entire basket. The company also recommends securing the foil and keeping it away from the heating element.

However, not every manufacturer gives the same advice.

Philips says it does not recommend using tin foil or baking paper in its Airfryers. According to Philips, covering parts of the basket or pan can reduce airflow and cooking performance. Loose foil may also be drawn toward the heating element.

So the safest general rule is simple:

Check your air fryer’s manual before using aluminum foil.

If the manufacturer says not to use it, follow that recommendation.

Why Airflow Matters

An air fryer cooks food by circulating hot air around it.

That circulation is one of the reasons foods such as fries, chicken wings, and breaded foods can develop a crisp exterior.

If you cover too much of the basket with foil, you may block some of that airflow. The result can be slower or less even cooking.

This is why lining the entire basket with a large sheet of foil usually isn’t a good idea, even with an air fryer that permits foil.

Instead, use only as much foil as you actually need and keep ventilation areas clear.

How to Use Aluminum Foil in an Air Fryer

If your air fryer manufacturer allows aluminum foil, a few simple precautions can make a big difference.

1. Don’t Cover the Entire Basket

Avoid wrapping the whole basket or blocking holes and vents designed for air circulation.

Use a smaller piece of foil that fits underneath the food without unnecessarily covering the cooking area.

2. Keep the Foil Away From the Heating Element

Loose aluminum foil can move around as powerful hot air circulates inside the appliance.

Keep it away from the heating element and other areas prohibited by your manufacturer.

3. Put Food on Top of the Foil

Don’t place a loose, lightweight sheet of foil in the air fryer and then run it empty.

Food can help keep the foil securely in place. COSORI specifically recommends placing food securely on top when foil is used.

4. Don’t Assume Every Air Fryer Is the Same

Basket designs, heating systems, and manufacturer instructions vary.

A method that is acceptable for one air fryer may not be recommended for another. Your model’s manual should take priority over general advice you find online.

When Is Aluminum Foil Useful?

Foil can be convenient when cooking foods that produce drippings or leave behind sticky residue, provided your air fryer permits its use.

It may also be useful when you want to keep certain foods contained rather than placing them directly on the basket.

But foil isn't necessary for everyday air frying.

For foods where maximum crispiness is the goal, leaving more of the basket exposed can actually be beneficial because hot air can circulate more freely around the food.

Can You Line the Bottom of an Air Fryer With Foil?

This depends on what you mean by the “bottom.”

You should not automatically place foil beneath the basket or over areas designed to collect grease and circulate air.

Philips specifically warns that putting foil in the bottom of the pan can disrupt airflow and lead to poorer cooking results in its Airfryers.

If you want to use foil for easier cleanup, check your model’s instructions to see exactly where liners are permitted.

Can You Wrap Food in Foil in an Air Fryer?

With an air fryer that permits aluminum foil, wrapping certain foods in foil may be possible.

However, wrapping food changes the way hot air reaches its surface.

If you completely wrap something that you want crispy, the foil can trap moisture and prevent the exterior from crisping as effectively.

So think about the result you want. Foil may be useful for containing moisture or drippings, but direct exposure to circulating air is usually more helpful when crispiness is the priority.

Aluminum Foil vs. Parchment Paper

Both are commonly considered as air fryer liners, but neither should automatically be considered safe for every air fryer.

Manufacturer instructions still come first.

If you use an approved liner, make sure it cannot move into the heating element and that it does not unnecessarily restrict airflow.

Perforated air fryer liners can allow more air to circulate than a solid sheet, although you should still check whether your particular air fryer permits them.

Common Mistakes to Avoid

The biggest mistake is assuming that because aluminum foil is oven-safe, it can be used anywhere inside an air fryer.

An air fryer relies heavily on rapidly circulating air, so loose materials and blocked vents can create problems.

Avoid using foil if your manufacturer advises against it. If foil is permitted, don't let it sit loose in the basket, cover ventilation areas, or extend toward the heating element.

And don't use more foil than necessary.

Frequently Asked Questions

Can aluminum foil catch fire in an air fryer?

Aluminum foil itself is commonly used at cooking temperatures, but loose foil can create a hazard if it moves toward or contacts a heating element. That is one reason manufacturers that permit foil recommend keeping it secured and away from heating elements.

Can I put foil in the air fryer while preheating?

It is better not to leave a loose sheet of foil in an empty air fryer. If your manufacturer permits foil, follow its placement instructions and make sure the foil is properly secured by food when required.

Does foil make food less crispy?

It can. Covering basket openings with foil may reduce airflow around the food, which can affect browning and crispiness.

Do all air fryers allow aluminum foil?

No. Manufacturer recommendations differ. COSORI provides instructions for using aluminum foil in its air fryers, while Philips says it does not recommend foil in its Airfryers.

Final Thoughts

So, can you put aluminum foil in an air fryer?

In many models, yes—but only if the manufacturer allows it.

When foil is permitted, keep it secure, don't block airflow, and keep it away from the heating element. Most importantly, check the instructions for your specific air fryer rather than assuming that advice for another model applies to yours.

A small piece of foil can make cleanup easier, but good airflow is more important than saving a few minutes at the sink.

How to Reheat Fried Chicken So It Stays Crispy

 

Fried chicken in an air fryer

Cold fried chicken can still taste great the next day. The challenge is getting the coating crispy again without drying out the meat inside.

The good news is that you don't need to fry it a second time.

The best way to reheat fried chicken and keep it crispy is to use an air fryer or oven, arrange the pieces in a single layer, and give hot air enough room to circulate around them.

For a few pieces, the air fryer is usually the most convenient option. For a larger batch, the oven makes more sense.

Here's how to do both—and what to avoid if you don't want soggy breading.

Best Method: Reheat Fried Chicken in an Air Fryer

An air fryer is particularly useful for reheating fried foods because circulating hot air can help dry and re-crisp the coating.

It's also convenient when you're reheating only a few pieces and don't want to heat an entire oven.

How to do it

1. Arrange the fried chicken in a single layer in the air fryer basket.
2. Leave some space between the pieces rather than packing them tightly together.
3. Reheat at about 350–375°F (175–190°C).
4. Flip the chicken partway through so both sides get exposure to the circulating air.
5. Continue heating until the coating is crisp and the chicken is hot throughout.
6. Check that the center has reached 165°F (74°C) before serving.

Exact reheating time will depend on the size and thickness of the chicken.

Small wings or tenders may heat relatively quickly, while a large breast or thigh can take longer.

Instead of relying entirely on a timer, check both the crust and the internal temperature.

Don't Overcrowd the Air Fryer

It can be tempting to squeeze every leftover piece into the basket.

That's usually a bad trade if crispiness is your goal.

An air fryer depends on hot air moving around the food. When chicken pieces are tightly packed together, some surfaces receive less airflow.

That can leave you with chicken that's crisp in one spot and soft or soggy in another.

If you have more chicken than comfortably fits in a single layer, reheat it in batches.

It may take a little longer overall, but the texture is likely to be better.

How to Reheat Fried Chicken in the Oven

The oven is a better option when you have several pieces to reheat at the same time.

The basic principle is the same: expose as much of the chicken as possible to dry heat while allowing air to move around it.

How to do it

1. Preheat the oven to around 375–400°F (190–205°C).
2. Place a wire rack over a baking sheet, if you have one.
3. Arrange the chicken in a single layer without stacking the pieces.
4. Reheat until the outside is crisp and the center is thoroughly hot.
5. Turn the pieces if needed for more even crisping.
6. Check for an internal temperature of 165°F (74°C).

A wire rack is helpful because it lifts the chicken above the baking sheet.

Without a rack, the bottom of the chicken sits directly against the pan, where moisture can collect and make the underside softer.

If you don't have a wire rack, you can still use a baking sheet. Just consider turning the pieces during reheating.

Air Fryer vs. Oven: Which Is Better?

Both can work well.

The better choice mostly depends on how much chicken you're reheating.

Use an air fryer when:

• you're reheating a few pieces
• you want fast reheating
• crispiness is a priority
• you don't want to heat a full-size oven

Use an oven when:

• you're reheating a larger batch
• the pieces won't fit comfortably in your air fryer
• you want to reheat everything at once

For one or two leftover pieces, I'd start with the air fryer.

For a box of takeout fried chicken, the oven is usually more practical.

Can You Reheat Fried Chicken in the Microwave?

Yes, but the microwave isn't the best choice if your main goal is crispy breading.

Microwaves are great at heating food quickly, but fried coatings can become soft as moisture and steam build up during reheating.

You may end up with hot chicken, but not necessarily crispy chicken.

If the microwave is your only option, use short heating intervals rather than overheating the chicken.

But if texture matters, an air fryer or oven is usually the better tool.

What About Using the Microwave First, Then the Air Fryer?

This can be useful for a particularly thick piece of chicken.

A short microwave warm-up can begin heating the center, followed by a brief trip to the air fryer to restore some crispness to the outside.

The disadvantage is that microwaving too long can soften the breading and start drying the meat.

If you try this method, keep the microwave portion short and finish the reheating in the air fryer.

Most normal-size pieces don't require this extra step, but it can be helpful when the outside is browning much faster than the center is heating.

Why Does Reheated Fried Chicken Get Soggy?

Fried chicken doesn't stay exactly the same after refrigeration.

Moisture from the chicken can migrate into the crispy coating while it sits in storage. That coating becomes softer than it was when freshly fried.

Reheating needs to do two things at once:

warm the meat inside and remove enough surface moisture to restore the crust.

That's why dry circulating heat works so well.

An air fryer moves hot air around the chicken, while an oven—especially with the chicken elevated on a rack—can expose more of the surface to dry heat.

Why Does Reheated Fried Chicken Get Dry?

The opposite problem can happen too.

You successfully make the coating crispy, but the meat inside becomes dry.

Usually, this means the chicken was heated longer than necessary.

Large pieces can make this tricky because the crust may be getting darker while the center is still warming.

A food thermometer is useful here. Instead of continuing to heat the chicken "just in case," you can check the center and stop once it has been reheated thoroughly.

Also remember that different pieces may finish at different times.

A small wing and a thick breast don't necessarily belong on the same reheating schedule.

Should You Add Oil When Reheating Fried Chicken?

Usually, you don't need much additional oil.

Fried chicken already contains oil in its coating, and reheating it in an air fryer or oven doesn't require another round of deep-frying.

If the coating looks extremely dry, a very light application of oil may help in some cases, but don't soak the chicken.

Adding a lot of oil won't automatically make leftover fried chicken crispier.

Should You Cover Fried Chicken While Reheating It?

Not if crispiness is your main goal.

Covering food traps moisture and steam. That's useful for foods you want to keep soft, but it's less helpful when you're trying to restore a crunchy fried coating.

For crispy fried chicken, you generally want the exterior exposed to hot, relatively dry air.

That's another reason an open rack or air fryer basket works well.

Can You Reheat Takeout Fried Chicken the Same Way?

Yes, as long as it was stored safely.

Takeout fried chicken can be reheated using the same air fryer or oven methods.

The important question is what happened to the chicken before it reached the refrigerator.

Perishable takeout food shouldn't sit at room temperature for extended periods before being refrigerated.

Reheating food doesn't erase unsafe storage conditions.

If you're not sure how long the chicken was sitting out before refrigeration, food safety matters more than saving the leftovers.

How Long Does Leftover Fried Chicken Last in the Fridge?

Cooked chicken should generally be used within 3 to 4 days when properly refrigerated at 40°F (4°C) or below.

That means a forgotten box of fried chicken that's been sitting in the refrigerator for a week shouldn't be rescued by putting it in the air fryer.

Reheating is not a way to make old or improperly stored chicken safe again.

When in doubt about how the chicken was stored, it's safer to discard it.

Reheat Fried Chicken to 165°F

When reheating leftovers, heat the chicken to an internal temperature of 165°F (74°C).

Check a thick part of the chicken with a food thermometer and avoid touching the bone when taking the temperature.

This is particularly useful with thick bone-in pieces because the crust can become hot and crispy before the center has fully reheated.

If that happens, lower or adjust the heat as appropriate for your appliance and give the center more time rather than judging doneness by the crust alone.

Common Fried Chicken Reheating Mistakes

Packing the Pieces Too Closely

Crowding restricts airflow and can prevent the coating from crisping evenly.

Leave room between pieces or work in batches.

Reheating Every Piece for the Same Amount of Time

A wing, drumstick, thigh, and breast aren't the same size.

Check smaller pieces earlier and remove them once they're ready.

Using Only the Microwave for Crispy Results

The microwave can make chicken hot, but it isn't particularly good at restoring a crunchy fried crust.

Use dry heat when crispiness matters.

Covering the Chicken

Covering traps steam around the crust.

Leave the coating exposed when reheating in the oven or air fryer.

Reheating It for Too Long

More heat doesn't always mean more crispness.

At some point, you're simply drying out the meat.

Stop once the coating is crisp, the center is thoroughly hot, and the chicken has reached a safe reheating temperature.

Quick Guide: Which Reheating Method Should You Use?

A few pieces: Air fryer

Large batch: Oven

Fastest option when texture doesn't matter much: Microwave

Best choice for crispiness: Air fryer or oven

Thick piece heating unevenly: Consider a short microwave warm-up followed by the air fryer

The goal isn't to make leftover fried chicken identical to chicken straight from the fryer.

It's to restore as much of that crispy exterior as possible without sacrificing the meat inside.

Frequently Asked Questions

What is the best way to reheat fried chicken and keep it crispy?

An air fryer is a convenient choice for a few pieces, while an oven works well for larger batches. In either case, arrange the chicken in a single layer and leave space for hot air to circulate.

What temperature should I use to reheat fried chicken in an air fryer?

Around 350–375°F (175–190°C) is a practical starting range. Because air fryers vary, check the chicken as it reheats rather than relying on time alone.

How do you reheat fried chicken without drying it out?

Avoid heating it longer than necessary. Check thick pieces with a food thermometer and stop once the chicken is thoroughly reheated to 165°F (74°C).

Why does fried chicken get soggy in the microwave?

The microwave heats moisture in the food, and the resulting steam can soften the fried coating. An air fryer or oven is better suited to restoring crispness.

Can you reheat fried chicken more than once?

For both quality and food-safety reasons, it's better to reheat only the amount you plan to eat. Keep the remaining properly stored chicken refrigerated until you need it.

Final Thoughts

If you want leftover fried chicken to stay crispy, give it heat, space, and airflow.

Use an air fryer for a few pieces or an oven for a larger batch. Keep the pieces in a single layer, avoid trapping steam around the coating, and don't heat the chicken longer than necessary.

Most importantly, start with chicken that was stored safely and reheat it thoroughly to 165°F (74°C).

You may not recreate the exact crunch of chicken straight from the fryer, but the right reheating method can get your leftovers surprisingly close.
