This complete guide to reheating pizza in air fryer works for all styles of air fryers and for thin-crust or regular-crust pizza.
Make sure the pizza slices do not overlap. Cook the pizza for 3-4 minutes and quickly open the air fryer basket to check the pizza.
If you feel it needs a little more time, then cook for another 1-2 minutes at a time, then check until done. Serve immediately.
