NOTES:
- Slicing tip: Aim for 1/8-inch thick slices — thicker chips won't crisp up properly.
- Ripeness: Use bananas that are yellow and firm with only minor freckling. Overripe bananas won't hold their shape.
- Storage: Store in an airtight container with a paper towel at the bottom at room temperature for up to 7 days, refrigerated up to 2 weeks, or frozen up to 2 months.
- Re-crisping: If chips soften, return to air fryer at 300°F for 2-3 minutes.
- Oven method: Bake at 225°F (110°C) on a parchment-lined sheet for 1.5-2 hours, flipping halfway through.
