Start by peeling and cutting your pineapple into even chunks. I make sure the pieces are similar in size so they cook evenly. Fresh pineapple gives the best texture and flavor compared to canned.
In a mixing bowl, toss the pineapple pieces with melted butter or oil. Then sprinkle brown sugar, cinnamon, and a pinch of salt. I gently mix until every piece is coated well.
Preheat your air fryer to around 380°F (193°C) for a few minutes. This step helps the pineapple start caramelizing immediately. It makes a noticeable difference in texture.
Place the pineapple chunks in a single layer inside the air fryer basket. Avoid overcrowding so the hot air circulates properly. I usually cook in batches if needed.
Cook for about 10–12 minutes, flipping halfway through. The edges will turn golden and slightly crisp. I always check for that caramelized look before removing them.
Let the pineapple cool slightly before serving. It becomes even sweeter as it rests. I love serving it warm for the best flavor experience.
