Roll the mixture into 1-inch meatballs, spray the air fryer basket with oil, and place the meatballs into it with space in between them.
Air fry the meatballs for 5 minutes. Then, flip them and air fry for another 5 minutes. They should be golden and register 165 degrees in the center with a meat thermometer.
Notes
Storage
Refrigerate for up to 3 days in an airtight container.
Freeze for up to 3 months in an airtight, freezer-safe container or heavy-duty freezer bag.
To reheat, defrost overnight in the refrigerator if frozen. Then microwave at 1-minute intervals.
Tips
We used lemon olive oil for flavor. If you don't have that, use regular olive oil and a tablespoon of lemon zest.
Preheat the air fryer for even cooking and accurate cooking times. It only takes about five minutes.
The mixture will feel a bit softer than you're used to if you normally use ground beef. That's okay!
Don't overwork your meat mixture. Mixing too much leads to contraction as the meatballs cook and dry out.
The meatballs are done when their internal temperature registers 165 degrees. Cooking times vary depending on the individual air fryer and the size of your meatballs.
