Preheat the air fryer to 380 degrees F (190 degrees C).

Cut the top off the head of garlic and place on a square piece of aluminum foil. Bring the foil up and around garlic. Pour olive oil on top and season with salt and pepper. Close ends of foil over garlic, creating a pouch.

Air fry until garlic is soft, 16 to 20 minutes. Open the foil pouch very carefully, as hot steam will escape.
