1-Gather and Prep Ingredients: First, choose your bananas carefully 2 green or yellow ones that aren’t ripe yet work best for that firm texture. Slice them into 1/4-inch thick pieces using a sharp knife. In a small bowl, mix 2 teaspoons of avocado or olive oil with 1/4 teaspoon of ground cinnamon if you’re using it. This prep takes just about 5 minutes and sets the stage for great results.

2-Preheat and Arrange: Next, preheat your air fryer to 300°F for 5 minutes. Place the sliced bananas in a large bowl and pour the oil mixture over them, tossing gently to coat evenly. Arrange the slices in a single layer in the basket, cooking in batches if needed to avoid crowding. This step ensures even cooking and helps achieve that lovely crispiness.

3-Cook and Flip: Air fry at 300°F for 25-28 minutes, flipping the slices halfway through. I learned through testing that this timing works well for most models, but keep an eye on them as variations can occur. The flipping helps both sides get that perfect golden color, turning simple bananas into irresistible chips.

4-Cool and Serve: Once done, remove the chips and let them cool for 5-10 minutes on a rack. This cooling is crucial for maximum crispiness, as I discovered during my trials. Serve them up as a snack or add to meals for a fun twist.
