Crispy, golden, and naturally sweet, these air fryer banana chips hit that satisfying crunch you crave from a snack without a single ingredient that needs to be avoided on a nightshade-free eating plan. Bananas, a squeeze of fresh lemon juice, a pinch of cinnamon, and a little salt — that's genuinely all it takes. The lemon juice does double duty here, keeping the slices from browning while adding a subtle brightness that balances the banana's natural sweetness. Slicing the bananas to a consistent 1/8-inch thickness is the real secret to getting that chip-like texture, and a mandoline makes it almost effortless. The air fryer does the heavy lifting at a low, steady heat, slowly drying the slices out until the edges turn golden and irresistible. Don't skip the cooling step on a wire rack — that's when they go from firm to genuinely crispy. Store-bought chips often come with long ingredient lists and seasoning blends that can be hard to vet, so making your own batch at home means you know exactly what's in every single chip.
