01 - Preheat your air fryer to 375°F for 3 minutes to ensure optimal cooking temperature.
02 - Pat the pineapple slices dry with paper towels to remove excess moisture, which helps achieve better caramelization.
03 - In a small mixing bowl, combine brown sugar, ground cinnamon, lime zest, and chili powder if using. Mix thoroughly to distribute spices evenly.
04 - Dip each pineapple ring into the sugar mixture, pressing gently to adhere the coating to both sides evenly.
05 - Place the coated pineapple rings in a single layer in the air fryer basket. Cook in batches if necessary to prevent overcrowding and ensure even cooking.
06 - Air fry for 10-12 minutes, flipping the pineapple rings halfway through the cooking time. The pineapple is ready when caramelized and golden brown with slightly charred edges.
07 - Serve the pineapple warm while still caramelized. Drizzle with honey or maple syrup if desired and finish with chopped fresh mint for a bright, refreshing contrast.
