How to Reheat Food in an Air Fryer: Pizza, Fries, and Fried Chicken
Last night's pizza is still in the fridge, and the takeout fries have lost their crunch. You want lunch, not another soggy microwave plate or a long wait for the oven. Reheating food in an air fryer gives those cooked leftovers a second chance: circulating hot air helps warm the center while bringing back a crisp edge. Start with the quick chart below, then use the pizza, fries, or fried chicken steps to match the food in front of you.
Before You Reheat Leftovers in an Air Fryer
Start with leftovers that were stored safely. Refrigerate cooked food within two hours, or within one hour if it was exposed to temperatures above 90°F (32°C). Use refrigerated leftovers within three to four days. If food sat out longer than the safe window, discard it rather than trying to rescue it with heat.
Check your air fryer's manual for its preheat and accessory instructions. Place food in a single layer with room for air to circulate; heat batches separately if necessary. If your model has a Reheat preset, it can be a convenient starting point, but the food's thickness and starting temperature still matter. Check before the suggested time is up, then add short increments as needed. Reheat leftovers until the center reaches 165°F (74°C); for thick pieces of meat, use a food thermometer instead of judging by the browned exterior.
Air Fryer Reheating Chart: Where to Start
| Leftover | Starting setting | When to check | What matters most |
|---|---|---|---|
| Pizza | 350°F (177°C) | Thin crust: 2–3 min; thicker slices: 4–5 min | One even layer; watch the crust and toppings. |
| French fries | 350°F (177°C) | 3–5 min | Spread out and shake or turn for even crisping. |
| Fried chicken | 375°F (190°C) | Boneless tenders: 4–5 min; bone-in pieces: 10–12 min | Flip halfway and check the thickest part. |
Use this chart for refrigerated, already-cooked food. Times change with slice thickness, portion size, and the air fryer itself. Check early and add another minute or two when needed, especially for thick pizza or bone-in chicken.
If you are starting with frozen food instead, see our guide to cooking frozen food directly in an air fryer.
How to Reheat Pizza in an Air Fryer
For leftover pizza, set the air fryer to 350°F (177°C) and follow your model's preheating instructions. Put one or two slices in a single layer, without stacking them. Check thin-crust slices after 2–3 minutes and thicker slices after 4–5 minutes. Remove delicate fresh toppings, such as basil or arugula, before heating and add them back afterward. The crust should be warm and crisp, while the cheese is heated through; keep checking if your slice is especially thick or heavily topped.
If you are wondering how long to reheat pizza in an air fryer, crust thickness is the first variable to consider. A small thin slice and a large deep-dish slice should not share one fixed timer. Lift a corner to check the base, and give a thicker slice a little more time if its middle is still cool.
How to Reheat Fries in an Air Fryer
To reheat French fries in an air fryer, spread refrigerated fries in an even layer rather than piling them into the basket. Start at 350°F (177°C) and check after 3–5 minutes, shaking the basket or turning the fries for more even heating. Give them enough room to crisp instead of trapping steam in a crowded pile.
Thicker fries may need more time. Stop when they are hot and the surface is crisp enough for you. If you have a large batch, work in smaller rounds so the fries heat evenly.
How to Reheat Fried Chicken in an Air Fryer
Set the air fryer to 375°F (190°C), place the cooked chicken in a single layer, and flip the pieces halfway through. Check boneless tenders after about 4–5 minutes and bone-in pieces after about 10–12 minutes. Smaller tenders and wings heat differently from thick, bone-in pieces, and a browned coating does not prove the center is hot. Check the thickest part before serving, using a food thermometer for larger pieces.
How long to reheat fried chicken in an air fryer depends on the cut and the appliance. If the coating is crisp but the middle is still cool, keep heating in short intervals. Avoid stacking pieces: hot air needs to reach every side.
More Leftovers to Reheat in an Air Fryer
Wondering how to reheat steak in an air fryer, or what to do with leftover ribs and egg rolls? Use these starting points for food that is already cooked and refrigerated. Keep each item in a single layer, and check the center before serving.
| Leftover | Starting setting | When to check | Quick tip |
|---|---|---|---|
| Steak | 350°F (177°C) | Start checking at 3–5 min | Turn once; thick or straight-from-the-fridge cuts may need longer. |
| Bone-in ribs | 350°F (177°C) | 13–15 min | Arrange in one layer; check the thickest section and watch any sauce. |
| Egg rolls | 350°F (177°C) | About 10 min | Leave space between rolls and turn halfway through. |
These are quick references, not full recipes. Size, filling, and your air fryer can change the time, so add heat in short intervals when needed.

Air Fryer Reheating FAQs
Can an air fryer be used to reheat food?
Yes. It works especially well for cooked leftovers with a crust or coating, such as pizza, fries, and fried chicken. Spread food out and check it early so the outside does not overcook.
How to reheat in an air fryer without drying it out?
Use a single layer, start with the food-specific setting above, and add time in short increments. Check chicken early; leaving it in after the center is hot can dry it out.
Can you put foil in an air fryer to reheat food?
Check your model's manual first; foil rules differ by air fryer. If your model allows it, keep foil secured under food and away from vents and heating elements. For fries, an uncovered basket leaves more room for circulating air.
What foods cannot be cooked in an air fryer?
Runny foods such as soup and thin sauces are a poor fit for an open air fryer basket. Reheat them on the stovetop or in a microwave instead. Wet batter can also drip before it sets.
