Air Fried Apple Chips

Preheat the air fryer to 350 degres F / 180 degrees C.
Thinly slice the apple using either a mandolin or a sharp knife.
Add apple slices to a bowl and combine with cinnamon.

Transfer half of the spiced apple slices to the air fryer basket, arranging in a single layer.
Cook for 8-10 minutes, turning and flattening them at least 2 times during the cooking process.
Remove the cooked apple chips, and then repeat the process with the rest of the apple slices.
