Preheat the air fryer to 250°F. If your model does not go that low, use the lowest setting and check the chips early.
02 -
Cut the bananas into even 1/8-inch rounds. Keep the slices as consistent as possible so they dry at the same pace.
03 -
Lay the slices on a board or plate and brush both sides lightly with lemon juice. Use just enough to coat the surface without making them wet.
04 -
Arrange the banana slices in a single layer in the air fryer basket. Air fry for 22-30 minutes, flipping once halfway through and removing any smaller chips that dry early.
05 -
Move the chips to a wire rack and cool for 10 minutes. They will crisp more as they cool.
06 -
Mix the sugar, cinnamon, and salt in a small bowl. Mist the cooled chips very lightly with oil, then toss gently with the cinnamon sugar until coated.
