Preheat air fryer to 375°F (190°C) for 3 minutes.

Place meatballs in the basket (lightly sprayed with oil).

Air fry for 6–8 minutes, shaking halfway, until browned and cooked through.

Assemble Casserole (3–5 minutes)

In a greased 6- or 7-inch baking dish, spread the mashed potatoes as the bottom layer.

Arrange cooked meatballs over the mashed potatoes.

Sprinkle shredded cheese on top.

Final Air Fry (8–10 minutes)

Place the casserole dish in the air fryer basket.

Air fry at 350°F (175°C) for 8–10 minutes, until cheese is melted and bubbly.

Optional: Broil for 1–2 minutes at the end for a golden top.

Serving Suggestions:

Garnish with chopped parsley or green onions.

Serve with a drizzle of brown gravy, marinara, or even barbecue sauce.

You can make this casserole ahead and store it in the fridge. Reheat at 320°F for 8–10 minutes.

Add sautéed onions, corn, or peas to the mashed potato layer for more flavor.
