Main Ingredients
- 2 pounds frozen meatballs (store-bought or homemade)
- 3 cups marinara sauce
- 2 cups shredded mozzarella cheese
- 1 tablespoon Italian seasoning
- ½ cup grated Parmesan cheese
Optional Ingredients
- 2 cups cooked pasta or cooked rice (for added bulk)
- Preheat and Prepare Your Baking Dish: Set your oven to 375°F (190°C). Use a generously sized casserole dish and lightly grease the bottom to prevent sticking.
- Layer the Ingredients: Spoon a layer of marinara sauce on the bottom of the baking dish to keep the casserole moist. Evenly distribute the frozen meatballs over the sauce, then sprinkle the Italian seasoning evenly on top.
- Add Optional Pasta or Rice: If using, scatter the cooked pasta or rice evenly over the meatballs to make the casserole heartier and stretch servings.
- Top with Cheese: Generously spread shredded mozzarella cheese over the entire casserole. Sprinkle grated Parmesan evenly on top for added richness and flavor.
- Bake and Serve: Cover the casserole with foil and bake for 30 minutes. Remove the foil and bake another 10 minutes until the cheese is bubbly and lightly golden. Let the casserole rest for a few minutes before serving.
Notes
- Choose quality meatballs—store-bought or homemade—for best flavor.
- Don’t skip the sauce layer to prevent sticking and keep meatballs juicy.
- Cover with foil during baking to retain moisture and prevent drying out.
- Fresh herbs like basil or parsley sprinkled on top before serving add brightness.
- Let the casserole rest a few minutes after baking for easier slicing and serving.
