Crispy, golden, and lightly sweet, these homemade banana chips are the kind of snack that disappears fast. A quick toss in fresh lemon juice keeps the slices from browning and adds a subtle brightness that balances the natural sweetness of the banana. Optional cinnamon and salt take things to the next level, giving each chip that irresistible sweet-savory edge. The air fryer does the heavy lifting here — low heat and a careful flip midway through are all it takes to get that satisfying crunch without any deep frying. Slicing the bananas to a consistent 1/8-inch thickness is the real secret, so a mandoline is your best friend if you have one. Store-bought chips often come processed on shared lines with tree nuts, so making your own batch at home means you know exactly what went into every single chip. Let them cool completely on a rack and watch them crisp up right before your eyes.
