Reheat pizza in an air fryer at 350°F (175°C) for 3–4 minutes. This is the best method available for leftover pizza, and it is the clearest single argument for owning the appliance — the base re-crisps rather than going soft in a microwave or leathery in an oven.
Which reheating method works best?
| Method | Time | Base | Cheese |
|---|---|---|---|
| Air fryer, 350°F / 175°C | 3–4 min | Crisp | Properly melted |
| Microwave | 45 sec | Soft, floppy | Melted, then rubbery |
| Oven, 375°F / 190°C | 10 min + preheat | Good | Good, edges dry |
| Frying pan, covered | 5–6 min | Very crisp | Slow to melt |
A microwave heats the water inside the crust and drives it outward, which is exactly what softens the base. An air fryer drives moisture off the surface instead, which is why it restores texture rather than destroying it.
How long does it take by Type?
| Type | Temperature | Time |
|---|---|---|
| Thin crust slice | 350°F / 175°C | 3–4 min |
| Regular crust slice | 350°F / 175°C | 3–5 min |
| Deep dish / thick crust | 325°F / 165°C | 5–7 min |
| Stuffed crust | 350°F / 175°C | 4–6 min |
| Frozen leftover slice | 350°F / 175°C | 6–8 min |
| Whole leftover personal pizza | 350°F / 175°C | 4–6 min |
Deep dish runs cooler and longer so the centre warms before the crust darkens.
How many slices fit?
| Basket size | Slices |
|---|---|
| 3–4 qt (3–4 L) | 1 |
| 5–6 qt (5–6 L) | 2 |
| 7–8 qt (7–8 L) | 3 |
| Dual basket, per drawer | 1–2 |
| Air fryer oven | 4–6 |
Flat, not overlapping. Stacked slices steam the one underneath and defeat the purpose.
Do you need to preheat?
Yes, 3 minutes, and it matters more here than the short cook time suggests. A cold basket lets the base absorb moisture before it starts drying, which is the whole problem you are trying to solve.
Should you use parchment or foil?
Neither, for a single slice — direct contact with the basket floor is what crisps the base. If cleanup is a concern, use perforated parchment, which still lets air through.
Never use foil under the pizza. It blocks heat to the base and produces exactly the soft result you were avoiding.
Why is the cheese burning before the base crisps?
The element is above the food and the fan pushes heat downward onto the toppings. Drop to 325°F (165°C) and add 2 minutes — the base needs time, and lower heat gives it time without punishing the cheese.
Can you reheat frozen leftover pizza?
Yes, straight from frozen at 350°F (175°C) for 6–8 minutes. Do not thaw — a thawed slice releases moisture into the crust and reheats soggy.
What about reheating a whole pizza?
A whole 12-inch pizza does not fit a basket model. Cut it into quarters and reheat in batches, or use an air fryer oven. Reheating in rounds is fast enough at 3–4 minutes each that it is rarely a problem.

Frequently asked questions
What temperature to reheat pizza in an air fryer?
350°F, or 175°C, for 3–4 minutes for a standard slice.
Is an air fryer better than a microwave for pizza?
Considerably. A microwave softens the base by driving moisture into it; an air fryer dries the surface and restores the crust.
Do I need to preheat?
Three minutes. A cold basket lets the base go soggy before it starts crisping.
Can I reheat more than one slice?
Two in a 5–6 qt basket, laid flat without overlapping. Stacking steams the lower slice.
Why is my crust still soft?
Foil or solid parchment underneath, or no preheat. The base needs direct contact with the hot basket.
How do I reheat deep dish?
325°F (165°C) for 5–7 minutes. Lower and slower so the thick centre warms before the crust darkens.
