Slice the peaches in half and carefully remove the pits.

Lay the peaches on a two sheets of aluminum foil, cut side up (two halves per sheet of aluminum foil). Sprinkle each peach half with cinnamon and brown sugar.

Bring the foil up around the peaches, creating a little pouch, being careful to keep the peaches flat against the bottom of the foil. Place the foil pouches in the air fryer basket.

Air fry at 350 degrees F for 8 to 14 minutes, based on the ripeness of the peach – soft, juicy, ripe peaches will take 8-9 minutes, slightly soft ripe peaches will take 10-12 minutes, and slightly underripe peaches will take 13-14 minutes.

Allow the peaches to stay in the foil, unwrapped, for 5 minutes to continue cooking and start to slightly cool. Serve as desired!
