Crispy, golden, and lightly sweet, these air fryer 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 up a notch, giving each chip a warm, slightly savory edge that makes it hard to stop at just one handful. Store-bought banana chips can be a minefield — processed on shared lines with all kinds of tree nuts, including brazil nuts. Making your own at home with just a few clean, simple ingredients means you know exactly what went into the bag. The ingredient list here is short and straightforward, so there's no guesswork involved. The real secret to getting that satisfying crunch is slicing the bananas to a consistent 1/8-inch thickness and letting the chips cool completely on a wire rack after air frying — they firm up beautifully as they rest. Firm, ripe bananas (not overripe) are key, since they hold their shape through the cooking process and crisp up rather than turning mushy. Once you nail the technique, this becomes one of those recipes you'll come back to again and again.

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.
