Spray the air fryer basket with non-stick cooking spray.
In a large mixing bowl, combine all the ingredients.
Using clean, dry hands, work the mixture together until well combined. Try not to compact it too much, you want it mixed, but not smashed.
Form into 1” spheres and then cook in batches at 400 degrees F for 14 minutes per batch. If the meat is sticking to your hands, drizzle them with olive oil. This will help crisp the outside of the meatball and prevent them from sticking to your hands.
Enjoy with pasta or as an appetizer.
Store in a container in the fridge for up to 5 days.
