Stir together cinnamon and brown sugar in a small bowl until thoroughly blended. Start with 2 tablespoons of brown sugar and 1 teaspoon of cinnamon for every 8-10 pineapple slices, adjusting to match how sweet you like it.
02 -
Put the pineapple slices on a tray lined with parchment or wax paper. Cover each slice generously on both sides with the sugar-cinnamon mix.

Give the air fryer basket a light coat of oil using a spray or brush to keep things from sticking. This will also help with caramelizing and make cleanup easier.
04 -
Place the pineapple rings evenly spaced in one layer in the air fryer basket so the air can circulate. Work in smaller batches, if necessary, and avoid overlapping. Cook at 400°F for roughly 14–16 minutes, turning them over halfway through (about 7–8 minutes in).
05 -
For the rest of the pineapple, shorten the cooking time by 2–3 minutes since the fryer will already be hot. Keep a close eye—caramelization can happen more quickly now.

Remove the golden, caramelized pineapple slices with tongs and set them on a serving plate. They're great warm—try them with a scoop of ice cream, whipped cream, or just by themselves!
