Start with a whole head of garlic. With a sharp knife, cut through the papery skin, to remove about ½-inch off of the top (not the root end) to reveal the cloves inside.
Place the root side of the garlic onto a piece of aluminum foil. Drizzle the olive oil over top of the cut side. Sprinkle with salt.
Pull the sides of the foil up and around the head of garlic and pinch it together at the top to enclose.
Air fry at 400°F for 30 minutes. Leave the garlic in the air fryer with it turned off for 15 more minutes. Remove from the air fryer and let cool to room temperature.
Once the pouch is cool enough to handle, remove the head of garlic. Press on the sides of the head to pop out the softened cloves from the papery skin.
