Add all of the ingredients to a mixing bowl and mix well with a wooden spoon.
Use a medium cookie scoop to portion into 20 meatballs. Roll each into a ball.
Brush your air fryer basket with oil. Place the meatballs in the basket in a single layer. You may need to work in batches, depending on the size of your air fryer.
Cook at 400 degrees for 7 minutes or until the meat reaches 165 degrees.
Remove the cooked meatballs to a plate and cover with foil while cooking any remaining meatballs.
Notes
Serve over pasta or with warm marinara sauce for dipping.
