1. Put the ground beef in a bowl and add the other ingredients. Then, gently fold the ingredients into the beef with a cold fork to mix evenly.
2. Make two-inch-sized meatballs from the ground beef, and arrange them in one layer inside the air fryer basket.
3. Lower the basket into a 400F air fryer and cook for 10 to 12 minutes. The meatballs are ready when cooked through or read the 165F on a probe thermometer.
