Peel your bananas and slice them into thin rounds, about 1/8 inch thick. The thinner you slice them, the crispier they'll get. Try to keep the thickness consistent for even cooking.
02 -
Arrange your banana slices in a single layer on a large plate, baking sheet, or piece of parchment paper. Using a pastry brush, lightly coat the top of each slice with olive oil (or give them a quick spritz with olive oil cooking spray). Sprinkle with a little salt, then flip each slice and repeat the oil and salt on the other side.

Place the seasoned banana slices in your air fryer basket, making sure they're in a single layer without overlapping. You'll likely need to work in batches depending on the size of your air fryer. Don't crowd them or they won't crisp up properly.
04 -
Set your air fryer to 360°F and cook for about 12 minutes, until the banana chips turn a beautiful golden color with no soft spots remaining. Keep an eye on them toward the end as they can go from perfect to overdone quickly.

Once done, place the air fryer basket on heat-resistant pads and let the chips cool for about 5 minutes. Then transfer them to a wire cooling rack for another 5 minutes to fully crisp up. The cooling step is crucial for achieving that satisfying crunch! Taste and add a final sprinkle of salt if needed before serving.
