Yes! Preheat the air fryer at 200°C/400°F for 3 minutes. Line the basket with a sheet of aluminum foil and spray with cooking oil (or lightly brush the foil with oil). Place the meatballs on it and air fry for 10 minutes, then flip the meatballs and air-fry for another 6-8 minutes until cooked. Use a digital kitchen thermometer to ensure that the meatballs have reached an internal temperature of 74°C/165°F and are cooked. Transfer to a plate and then air fry the next batch.
