Ingredients You’ll Need
- 1 lb frozen meatballs: Any brand works, but homemade adds a personal touch.
- 3 cups marinara sauce: Use your favorite store-bought version or homemade for a richer flavor.
- 2 cups cooked pasta: I prefer penne or rotini, which hold sauce well.
- 1 cup shredded mozzarella cheese: This is essential for that cheesy goodness. Feel free to substitute with vegan cheese if needed.
- ½ cup grated Parmesan cheese: Adds a nutty flavor; you could swap with nutritional yeast for a dairy-free version.

- 1 tsp Italian seasoning: This gives the dish its lovely herby aroma. If fresh herbs are available, consider using them for a brighter flavor.
How to Make Dump and Bake Meatball Casserole
- Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
- Combine Ingredients: In a large mixing bowl, stir together the frozen meatballs, marinara sauce, and cooked pasta until everything is well coated.
- Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
- Add Cheeses: Sprinkle the mozzarella and Parmesan cheese generously over the top.
- Season: Dust the dish with garlic powder and Italian seasoning for that extra kick.
- Bake: Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and continue baking for an additional 15 minutes, or until the cheese is bubbly and golden.
- Cool Slightly: Let it cool for about 5-10 minutes before serving – this will help it set a bit and make serving easier.
Storing & Reheating
To store your meatball casserole, cover it tightly with plastic wrap or aluminum foil and keep it in the refrigerator for up to 3 days. If you plan to stash it longer, transfer it to an airtight container and freeze for up to 3 months. When you’re ready to enjoy it again, simply reheat slices in the oven at 350°F (175°C) for about 20-25 minutes or until heated through. Just a note: the texture may vary a bit after freezing, but refreshing it with a sprinkle of extra cheese can bring back some of that delicious gooeyness!
Chef’s Helpful Tips
- Make sure your meatballs are evenly spaced in the dish to cook uniformly.
- If using homemade meatballs, cook them ahead of time to ensure they’re hot and ready to mingle with the sauce.
- Experiment with different pasta types; whole wheat or gluten-free options work great too.
- If you like a bit of crunch, consider sprinkling some breadcrumbs on top before baking.
- For added creaminess, stir in a little cream or cream cheese before baking!
Dump and Bake Meatball Casserole truly encapsulates what comfort food is all about. It’s easy to prepare, resonates with nostalgia, and is perfect for making new memories around the table.
