A quick and easy dump and bake meatball casserole with just five ingredients, perfect for busy weeknights. This comforting dish combines frozen meatballs, creamy marinara sauce, and melted mozzarella cheese for a hearty, family-friendly meal.
Do not thaw meatballs before baking to keep them moist. Use quality marinara sauce for best flavor. Cover with foil if cheese browns too fast. Let rest 5 minutes before serving. For a crispier cheese top, broil 1-2 minutes watching closely. Dairy-free and gluten-free substitutions are possible.
