Preheat your air fryer to 390°F for about 3-5 minutes.

Place the frozen meatballs in the air fryer basket, arranging them in a single layer.

Spray the meatballs.

Cook the meatballs in the air fryer at 390°F for 5-6 minutes, shaking the basket halfway through the cooking time for even heating.

Once the meatballs are heated through and browned, carefully remove them from the air fryer.

Serve immediately.
