Toss apple slices with melted butter until evenly coated.
Mix sugar, cinnamon, and nutmeg together, then sprinkle over the apple slices and toss to coat.
Arrange apple slices in a single layer in the air fryer basket.
Air fry at 380°F for 8–10 minutes, shaking the basket halfway through, until edges are caramelized.
Serve warm with caramel sauce or whipped cream for dipping.
Tip: Use a mandoline to get perfectly even slices so they cook at the same rate. Firmer apple varieties like Fuji or Honeycrisp hold their shape better.
