Ingredients
  

  • 1 lb frozen or homemade meatballs cooked
  • 4 cups mashed potatoes fresh or leftover
  • 1 cup brown gravy homemade or store-bought
  • 1 cup shredded mozzarella or cheddar cheese
  • Salt and pepper to taste

Instructions
 

  • Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or cooking spray.
  • Arrange cooked meatballs evenly across the bottom of the baking dish, spacing them about an inch apart.
  • Pour brown gravy evenly over the meatballs, ensuring each meatball is coated.
  • Dollop mashed potatoes over the gravy-covered meatballs. Use a spatula to spread evenly, creating gentle peaks and valleys.
  • Sprinkle shredded cheese generously over the potato layer.
  • Bake for 20-25 minutes until cheese melts and begins bubbling, with edges lightly browning.
  • Optional: Switch to broil for final 2-3 minutes for golden-brown cheese top.
  • Let rest 5-10 minutes before serving to allow layers to set properly.
