01 - Preheat air fryer to 375°F for 3 minutes before cooking.
02 - Pat pineapple slices dry with paper towels to remove excess moisture for better caramelization.
03 - Combine brown sugar, cinnamon, lime zest, and chili powder in a small bowl until evenly incorporated.
04 - Press each pineapple ring into the sugar mixture, turning to coat both sides thoroughly.
05 - Place pineapple rings in a single layer in the air fryer basket, cooking in batches if needed to prevent overcrowding.
06 - Cook at 375°F for 10-12 minutes, flipping halfway through, until edges are golden brown and caramelized.
07 - Transfer to a serving platter, drizzle with honey or maple syrup, and sprinkle with fresh mint leaves.
