Air Fry: Arrange meatballs in air fryer basket, spaced evenly apart.
(Note: You'll have to cook these in at least two batches or freeze half the meatballs for another meal.*) Cook the meatballs for 7-9 minutes, flipping them about halfway through the cooking process (or when your air fryer beeps at you). Use a meat thermometer to check the internal temperature of the meatballs, which should reach 160-165°F to ensure they are fully cooked and safe to eat.
