The cooking time will depend on the type of meat you are using, how big your meatballs are, and if you are using an oven or an air fryer. I have made this recipe in The Instant Pot Vortex, The Instant Pot Crisp Lid, and Cosori Air Fryer. The cooking time is about a minute for each. So I cooked mine in the air fryer for about 12 minutes, but the best way to determine if your meatballs are done is to use a meat thermometer. The meatballs should be cooked to 165 F.
