Step by step

Method

4 steps

1. 1

   Preheat the air fryer to 350°F for 2–3 minutes so the basket is hot when the slices go in.

2. 2

   Place 1–3 cold leftover pizza slices in a single layer — never stack. Use perforated parchment if your cheese tends to drip. Optional: a light mist of water on very dry crust edges so they don't scorch before the cheese melts.

3. 3

   Air fry 3–5 minutes until the cheese is bubbling again and the underside of the crust is crisp when you lift a corner. Thin crusts finish closer to 3; thick or heavily topped slices need nearer 5. Peek early — leftover pizza goes from revived to tough fast.

4. 4

   Finish with a pinch of Parmesan or red pepper flakes if you want. Rest 30 seconds so the cheese sets slightly, then eat. You want revived leftover pizza with bubbling cheese and a crisp underside — not a soggy microwave slice or a dried-out cracker crust.
