Crunchy, lightly sweet, and genuinely satisfying, these air fryer banana chips hit that snack craving without sending your blood sugar on a rollercoaster. Firm, ripe bananas are sliced thin and cooked low and slow at 300°F, which draws out moisture gradually and creates a crisp chip rather than a soft, caramelized bite — a small but important distinction when you're watching how quickly carbohydrates hit your system. A splash of fresh lemon juice keeps the slices from browning and adds a subtle brightness, while optional cinnamon brings warm flavor and is a well-loved addition in blood sugar-conscious cooking. The ingredient list is refreshingly short and completely whole-food, so there are none of the added sugars, seed oils, or mystery additives you'd find in a store-bought bag. Letting the chips cool fully on a wire rack is the secret step that takes them from chewy to genuinely crispy — patience pays off here. Make a double batch, because these disappear fast and keep beautifully once they've cooled completely.

Using a mandoline or a sharp knife, slice the peeled bananas into rounds about 1/8-inch (3mm) thick — uniform thickness is key so the chips dry evenly.
