A cold slice from the fridge does not have to be a disappointment. To reheat pizza in an air fryer, set it to 350F, lay the slices in a single layer, and give them 3 to 5 minutes. That is the whole method for a thin slice: crisp on the bottom, melted on top, no soggy middle, and faster than waiting for the oven to heat.
The catch is that one temperature and time does not fit every pizza. A foldable New York slice and a two-inch-thick Detroit square reheat on opposite ends of the dial. This guide gives you tested air fryer times by style, the short version of why the air fryer works so well, and the mistakes that turn a good slice rubbery.
Who this is for: anyone with leftover pizza and an air fryer who wants it to taste reheated, not microwaved. Already at the oven? Our companion guide on reheating pizza in the oven covers that method by style.
TL;DR
- Thin slices (Neapolitan, New York, tavern): 350F, single layer, 3 to 5 minutes.
- Thick slices (Detroit, Sicilian, grandma): drop to 320 to 325F for 6 to 9 minutes so the dense center heats before the top scorches.
- Frozen leftover slice: no need to thaw; about 330F for 6 to 8 minutes.
- No long preheat needed. The air fryer is up to temperature almost instantly.
- Skip: lining the basket with parchment the whole time (blocks airflow), foil (traps steam), overcrowding, and the microwave (steams the crust limp).
- The air fryer is one of the best reheating methods there is. In Food & Wine’s six-method test, it scored 9 out of 10, second only to the covered skillet.
Why the air fryer reheats pizza so well
An air fryer is a small convection oven. A fan drives hot air fast around a tight chamber, which does two things a microwave cannot: it crisps the bottom of the crust by direct dry heat, and it melts the cheese from above at the same time. That dry, fast heat is exactly what stale pizza needs.
Cold pizza goes firm and dull because of starch retrogradation, the same process that stales bread. As Serious Eats explains in its pizza-reheating breakdown, the starch molecules in the crust recrystallize as they cool, which is what makes a day-old slice feel hard and dry. Gentle, even heat reverses enough of that to bring the crust back, and the air fryer delivers it faster than a full-size oven because there is so little space to heat.
The results back this up. When Food & Wine tested six ways to reheat a day-old slice, the air fryer scored 9 out of 10, finishing second only to a covered skillet (10 out of 10) and ahead of the oven, grill, toaster oven, and microwave, crisping the slice in about two and a half minutes. The skillet edges it out for a single thin slice, but the air fryer is more hands-off and handles a few slices at once, which makes it the easiest everyday choice.
How to reheat pizza in an air fryer
The basic method takes one slice or four. Here is the full sequence.
- Take the chill off (optional but better). Let the slices sit on the counter for 5 to 10 minutes while you get set up. A slice straight from the fridge can heat unevenly, with the cheese bubbling before the center warms.
- Set the air fryer to 350F. No long preheat is needed; the chamber is hot in a minute or two. Run a 2-minute preheat only if you want the maximum crisp.
- Arrange the slices in a single layer. Lay them flat in the basket with space between them so air can circulate around each one. Do not stack or overlap slices; the touching edges will steam instead of crisp.
- Cook 3 to 5 minutes for a thin slice. Start checking at 3 minutes. Air fryers run hot and fast, and models vary, so the first time you reheat in yours, watch it.
- Pull it when the bottom is crisp. The slice is done when the cheese is melted and bubbling and the underside is firm and crisp when you tap it, not just when the top looks hot.
That is it. No oil, no foil, no parchment for a standard slice. If you want to learn your machine, do one slice first and note the exact time; you will use the same number every time after that.
Air fryer reheat times by pizza style
This is where one temperature stops working. A thin slice wants a fast, hot blast; a thick slab wants lower heat and more time so the dense interior catches up before the cheese on top burns. These are our tested starting points; adjust by a minute for your machine.
| Pizza style | Temp | Time | Notes |
|---|---|---|---|
| Neapolitan (thin, soft center) | 350F | 3 to 4 min | The wet, tender center reheats fast; do not overdo it or the rim hardens |
| New York (thin, foldable) | 350F | 3 to 5 min | The air fryer’s best case; the bottom re-crisps quickly |
| Thin-crust / tavern | 350F | 3 to 4 min | Already crisp, so just reheat; watch it so it does not turn to a cracker |
| Detroit (thick, cheesy edge) | 325F | 6 to 8 min | Lower heat lets the dense crumb heat through before the top scorches |
| Sicilian / grandma (thick) | 325F | 6 to 8 min | Same logic; if the top darkens early, loosely tent a small piece of foil for the last minutes |
| Deep dish (very thick) | 320F | 8 to 10 min | The hardest case; for a very deep slice the oven may heat the center more evenly |
| Frozen leftover slice | 330F | 6 to 8 min | No need to thaw; add a couple of minutes versus a fridge-cold slice |
The pattern is simple: the thicker the slice, the lower the temperature and the longer the time. A 350F blast that perfects a New York slice will char the top of a Detroit square long before the middle is warm. If you mostly eat one style, learn its number and stop thinking about it. For a refresher on the styles themselves, see our guides to New York crust and Detroit-style pizza.
Basket vs oven-style air fryers
The method is the same in both designs, with one adjustment for capacity. A basket air fryer concentrates airflow from below and crisps the bottom aggressively, which is ideal for pizza; just do not crowd the basket. An oven-style air fryer (the toaster-oven shape) holds more slices on a rack, but the airflow is a little gentler, so add roughly a minute and rotate the tray once if your model has hot spots.
Whichever you have, the single-layer rule is the one that matters. The air fryer’s whole advantage is air moving around the slice. Pile slices on top of each other and you have built a small steam oven, and the bottoms come out pale and limp.
Reheating frozen or take-and-bake pizza in an air fryer
The air fryer is not just for leftovers. A frozen leftover slice goes straight in, no thawing, at about 330F for 6 to 8 minutes until the center is hot. The extra time accounts for melting the ice crystals before the crust can crisp.
Raw frozen or take-and-bake pizza works too, with a caveat: a whole frozen pizza usually will not fit a basket model, so cut it down or use an oven-style air fryer, and follow the package temperature. The risk with raw dough is a top that looks done while the center is still doughy, so check that the middle is fully cooked, not just browned. If you run into a gummy center, that is a baking-through problem, and our notes on pizza oven temperature and dough troubleshooting explain why direct bottom heat matters.
Getting the toppings and cheese right
The crust and the cheese are forgiving in an air fryer. The toppings are where slices go wrong, because fast convection heat hits them harder than a slower oven does.
Sturdy toppings love the air fryer. Pepperoni re-crisps and its edges cup and char a little, which most people consider an upgrade over the original. Sausage, onions, peppers, and olives all reheat fine right on the slice. The hot air does dry exposed toppings slightly, so for a heavily loaded slice, lean toward the lower end of the time so the cheese stays melted rather than tightening up.
Delicate toppings should go on after, not before. Fresh basil, arugula, prosciutto, a runny egg, or a drizzle of fresh ricotta will scorch, wilt, or overcook under direct air-fryer heat. Pull those off before reheating if you can, warm the slice, then add them back fresh. A reheated Neapolitan slice topped with basil added at the end tastes far closer to new than one with blackened, dried-out leaves. The same goes for a white pie with delicate cheeses: lower heat, shorter time, and finish with anything fresh.
How to store leftover pizza so it reheats well
A good reheat starts the night before. Pizza left in the cardboard box on the counter dries out and risks sitting in the food-safety danger zone, and a slice that started out stale reheats worse than one stored properly.
Refrigerate leftovers within about two hours of baking. The best way to store slices is in a single layer in an airtight container, or stacked with a piece of parchment between each slice so the cheese and toppings do not fuse and the bottoms do not go soggy against each other. A zip-top bag with the air pressed out works too. Stored this way, pizza keeps well in the fridge for 3 to 4 days, and each slice goes into the air fryer flat and ready.
If you know you will not get to the leftovers in a few days, freeze them. Wrap slices individually and freeze for up to a couple of months, then reheat straight from frozen at about 330F for 6 to 8 minutes, no thawing. Storing carefully now is what lets the air fryer do its best work later.
Air fryer vs oven vs skillet vs microwave
The quick verdict, since the air fryer is rarely your only option:
- Skillet (covered, on the stovetop): the best result for one or two thin slices. A dry pan re-crisps the bottom while a few drops of water under the lid steam-melt the cheese. Food & Wine and Serious Eats both rate it the winner. Slower to scale past two slices. This is the same conductive-heat idea behind a cast iron skillet pizza.
- Air fryer: nearly as good, more hands-off, handles several slices, no babysitting. The best everyday method for most people.
- Oven (with a preheated sheet or stone): the move for thick styles and for reheating a lot of pizza at once, though it needs a long preheat. Full method in our oven reheating guide, and the preheat logic in how to use a pizza stone.
- Microwave: last resort. It steams the crust limp every time. If it is all you have, microwave briefly to warm the center, then finish in the air fryer for 2 minutes to recover some crisp.
What to skip
The fast ways to ruin a good slice:
- Lining the basket with parchment for the whole cook. It blocks the airflow that crisps the bottom, which is the only reason to use an air fryer at all. Parchment for the first minute only, then pull it, or skip it.
- Foil. It traps steam against the crust and guarantees a soggy bottom, the same mistake as wrapping a slice in foil in the oven.
- Overcrowding. Stacked or touching slices steam each other. Single layer, with space, even if it means two batches.
- Too high a temperature on a thick slice. Blasting a Detroit or deep-dish square at 400F chars the cheese while the center stays cold. Lower and slower wins on thick pizza.
- The microwave as the finish. If you must use it, use it first to warm through, then crisp in the air fryer, never the other way around.
Crisp leftovers in under five minutes
The air fryer turns last night’s pizza into something genuinely good, not merely edible, and it does it faster than the oven with none of the babysitting the skillet needs. Remember the one rule that does the heavy lifting: match the temperature to the thickness. Thin and crisp wants 350F and a quick 3 to 5 minutes; thick and dense wants 320 to 325F and 6 to 9. Learn the number for the style you eat most, keep the slices in a single layer, and you will never microwave a slice again.
