Prep: In a large mixing bowl, combine the thinly sliced apples with granulated sugar and ground cinnamon.

Air Fry: Arrange apple slices in the air fryer basket, slightly overlapping is fine. Air fry at 350°F / 176°C for 12 minutes total, flipping the slices every 4 minutes for even crisping.

Rest: Remove from air fryer and let rest at room temperature - the apple chips will continue to become more crisp as they cool completely.
