Place the slices of pizza in the air fryer basket, ensuring that they aren't touching.
Cook for 3-4 minutes until the crust is crispy and the cheese is melted and hot. Thin-crust pizza will need less time, while a thicker crust will need more.
Serve with ranch or your favorite dipping sauce.
Notes
For faster clean up use air fryer parchment paper or a silicone baking mat.
