Can You Reheat Food in an Air Fryer?
Yes. For anything that's meant to be crispy, the air fryer is the best reheating tool in the kitchen. It brings the crunch back instead of steaming it soft the way a microwave does. Use a moderate setting, keep the food in a single layer, and pull it the moment it's hot through.
Here's the part the crispiness guides leave out. Reheating a leftover isn't only about texture. It's about getting the food back to a safe 165°F / 74°C all the way through, because that's the temperature that deals with anything that grew while it sat in the fridge. Crisp is the bonus. Safe is the actual job.
I've reheated most of my leftovers in a Platinum 7.6L basket-style unit for two years. It brings fried food and pizza back better than the microwave ever managed. It also dries out a plain chicken breast and does nothing useful for a bowl of soup, so part of this page is telling you when to walk past it and reach for something else.
Cooking something from scratch instead of reheating? Use the calculator for the time and temp.

The food is already cooked. You're warming the middle and firming the surface, not cooking from scratch, so you want a moderate setting, lower than the temperature you'd use to cook that same food the first time. Go in too hot and the outside darkens while the centre is still fridge-cold.
Single layer, same rule as always. Reheat a pile of fries stacked three deep and you get a hot top layer sitting on a cold middle. Spread them out so the hot air reaches every piece. If your food comes out soggy even on a fresh cook, a crowded reheat will be worse.
You don't need a full preheat for most reheats. The food isn't racing a raw-cook time, so a cold start just adds a minute or two. Where preheating earns its place is thin, crisp things like fries and pastry, for the same reason it matters when you preheat before cooking.
How long? Long enough to hit temperature
I'm not going to hand you one reheat time, because it would be wrong for half the people reading. A thin slice of pizza and a thick wedge of lasagne aren't the same job. Something straight from the freezer takes longer than the same food from the fridge. Thickness and starting temperature move the time more than the type of food does.
So go by the food, not the clock. Check early. For anything that was a protein, it's done when a thermometer reads 165°F in the thickest part. For fries, pizza or a pastry, it's done when the surface has firmed up and the centre is hot. Pull it right then. A reheat left too long crosses from warm into overcooked fast.
The 165°F rule, and when to bin it instead
Reheating brings food back up to temperature. It doesn't sterilise it. If a plate sat out on the counter for hours after dinner, or it's been shoved at the back of the fridge for the better part of a week, the air fryer can't rescue it. Heat doesn't undo the bacteria that already grew while it sat. When you're not sure, throw it out. That's a cheaper loss than the alternative.
Assuming the leftover was cooled and refrigerated properly, the safe target is the same one USDA gives for any reheated food: 165°F / 74°C all the way through. That's higher than some first-cook temperatures on purpose. A steak is safe at 145°F the day you cook it, but once it's a leftover you're reheating, the number to hit is 165°F. Cook time never proves it. A thermometer does.
What to reheat, and what to reheat some other way
This is the honest bit most reheat guides skip. The air fryer is not universally better than the microwave. It's better at some things and clearly worse at others, and knowing the split saves you a dried-out dinner.
It shines on anything with a surface that's supposed to be crisp. The one that turned me was leftover pizza. I used to microwave it and end up with a floppy, faintly greasy slice. The first time I put a couple of leftover slices in the air fryer instead, the crust firmed up, the cheese went properly melty again, and it wasn't a greasy mess. The microwave hasn't touched my leftover pizza since.
| Leftover | Best tool | Why |
|---|---|---|
| Fried chicken, wings, nuggets | Air fryer | Re-crisps the coating the microwave turns rubbery |
| Pizza | Air fryer | Crust firms, cheese re-melts, base stays whole |
| Fries, tots, spring rolls | Air fryer | Hot air brings the crunch back |
| Roast potatoes, pastry, breaded food | Air fryer | The surface re-crisps where a microwave sogs it |
| Rice and pasta in sauce | Microwave | Air fryer dries the top and there's no crust to save |
| Soup, stew, chilli | Stovetop | Liquid can't sit in a vented basket |
| Plain chicken breast, lean cuts | Microwave, covered | No surface to crisp, and the air fryer dries it out |
The pattern is simple. If the food has a surface you want crunchy, the air fryer wins. If it's moist, saucy or liquid, the thing you're chasing is even heat, not crisp, and the microwave or the stove does that with less fuss and no drying. Reheating leftover wings is the clearest case for the basket. Reheating last night's curry is not.
Basket-style vs oven-style
If you're on an oven-style unit rather than a basket, it holds more air, so a reheat usually wants roughly +2 to 5 minutes over what a basket needs at the same setting. Same idea as the basket-versus-oven difference on a fresh cook. More internal volume, a little more time to bring the food up. Check early either way and let the thermometer, not the timer, call it done.
When not to bother
Some leftovers just aren't an air fryer job. A bowl of soup or stew, a plate of saucy pasta, a scoop of plain rice, a lean piece of meat with no coating — all of these come out better, or at least no worse and with less effort, from the microwave or a pan. The air fryer's whole trick is crisping a surface with moving hot air. When there's no surface worth crisping, that trick works against you and dries the food out. Save the basket for the crispy stuff.
The short version
- Yes, and it's the best way to reheat anything that should be crispy.
- Use a moderate setting, lower than you'd cook the food from raw, in a single layer.
- Don't chase a fixed time. Thickness and fridge-cold-versus-frozen change it too much, so check early.
- Reheated food is safe at 165°F / 74°C all the way through. Use a thermometer for anything that was a protein.
- Food that sat out for hours, or has been in the fridge for most of a week, gets binned, not reheated.
- Soup, saucy pasta, rice and plain lean meat reheat better in the microwave or a pan. Save the basket for the crisp.
