Place two slices of pizza in the air fryer basket, making sure they don’t overlap. Cook on 350° F(175° C) for 3-4 minutes. Thicker pizza may need slightly longer, while thinner pizza may need slightly less time. Check at the 3 minute mark to gauge if it’s done or not.
Notes
If you have a basket air fryer, you will only be able to fit in about 2 slices of pizza at a time, depending on the size of your air fryer.
Don't try to stack them or the cheese will stick them together. You might want to use a parchment paper round in the bottom of the basket to prevent sticking and burning of cheese, though I've found this isn't really necessary. The crust gets crispier without anything in the bottom of the pan.
If you have a larger oven-style air fryer, you can re-heat as many slices as you want, as long as they fit on the tray without touching.
Air fryer temperatures can vary depending on the make and model, so always check your food for doneness and adjust the cooking time as needed.
Don't try to pick the pizza out of the hot basket with your hands. Always use tongs to get the pizza out so you don't burn yourself.
All air fryers have different wattage and may cook at different rates. You may need to adjust the time or temp for the best results.
