How to Reheat Pizza in an Air Fryer (Crispy Crust in 4 Minutes)

Why the Air Fryer Is the Best Way to Reheat Pizza

The microwave heats pizza by steaming it from the inside out, which is exactly how you turn a crisp crust soggy and good mozzarella rubbery. The oven does a fine job, but you'll wait 10 to 15 minutes for it to preheat — for a slice that only needs 4 minutes of actual heat.

An air fryer is basically a small, aggressive convection oven. It's at temperature almost instantly, and the circulating hot air re-crisps the bottom of the crust while the cheese re-melts on top. Crisp base, melty cheese, four minutes door to door. That's the whole pitch.

How to Reheat Pizza in an Air Fryer, Step by Step

Step 1 — Set the air fryer to 350°F. That's the sweet spot: hot enough to re-crisp the crust, cool enough that the cheese doesn't scorch before the base catches up.

Step 2 — Lay slices in the basket in a single layer with a little space between them. Don't stack or overlap — hot air needs to reach the crust, and a buried slice just steams.

Step 3 — Cook 3 to 4 minutes for thin crust, 4 to 6 minutes for thick crust or deep dish. Very deep Chicago-style slices do better a notch lower, around 325°F, so the middle heats through before the top over-browns.

Step 4 — Check at the 3-minute mark. When the cheese is bubbling at the edges and the underside is firm when you lift it with tongs, it's done. Every extra minute past that point is drying, not improving.

These times assume a basket-style unit like the Ninja air fryer we reviewed; smaller or oven-style models may need an extra minute.

Parchment Paper or Bare Basket?

Bare basket wins for crispness — direct contact with the perforated basket is what re-crisps the bottom of the crust. If your slice is loaded with greasy or droopy toppings, a sheet of perforated parchment keeps the cleanup sane and only costs you a little crunch.

One safety note: never preheat with an empty sheet of parchment in the basket. With nothing weighing it down, it can fly up into the heating element. Parchment goes in with the pizza on top of it, or not at all.

Day-Old vs. Frozen Leftover Pizza

Refrigerated slices are the easy case — the times above apply as written. Slices straight from the fridge crisp up beautifully because the crust is still relatively dry.

Frozen leftover slices don't need thawing. Put them in frozen at 350°F and plan on 5 to 8 minutes instead of 3 to 4, checking from the 5-minute mark. Thawing first on the counter just makes the crust wet, which is the exact problem you bought an air fryer to avoid.

What Not to Do

Don't microwave first and finish in the air fryer. Once the microwave has steamed the crust soft and chewy, no amount of hot air fully brings it back. Air fryer only, start to finish.

Don't crank it to 400°F or higher to save a minute. At that temperature the cheese burns and the pepperoni turns to charcoal before the crust has time to re-crisp. Reheating rewards patience — all four minutes of it.

And don't walk away. The line between perfectly bubbling and overdone is about 60 seconds, which is why the 3-minute check matters.

Once You've Mastered Leftovers

Reheating pizza is the gateway skill. The same machine turns out a legitimately good air fryer steak on a weeknight, and air fryer chicken tenders that beat anything from the freezer aisle. Leftover night is just the beginning.
