Start by selecting firm green or slightly yellow bananas, slice into uniform ¼ inch thick rounds using a sharp knife or mandoline slicer.

In a mixing bowl, combine banana slices with a light drizzle of avocado oil and cinnamon. Toss gently until each slice is evenly coated.

Preheat your air fryer to 350°F (175°C) for about 3–5 minutes.

Carefully place the coated banana slices in a single layer in the air fryer basket.

Air fry the banana slices at 350°F for 25-28 minutes, checking for desired crispness halfway through.

Once golden brown and crispy, remove the chips from the air fryer and allow to cool for 5-10 minutes.
