Whole portobello mushroom caps air-fry at 380 °F (193 °C) for about 12 minutes, flipping once halfway, until tender and juicy. Wipe them clean, remove the stems, and brush both sides with a balsamic-and-garlic marinade; cook them gill-side up at the end so they hold their juices instead of releasing them into the basket.
