Ingredients You’ll Need

The beauty of this Dump and Bake Meatball Casserole Recipe lies in how straightforward and pantry-friendly the ingredients are. Each component plays a crucial role in building layers of flavor, from the savory meatballs to the aromatic seasonings that elevate the sauce and pasta to new heights.

1 pound frozen meatballs: Choose beef, turkey, or chicken depending on your preference; they provide the hearty protein foundation for the dish.
2 cups uncooked pasta: Penne or rotini work wonderfully to catch the sauce and cheese, giving great texture throughout.
1 24-ounce jar marinara sauce: A robust, garlicky tomato base that ties everything together with a burst of flavor.
2 cups water or beef broth: Adds moisture so the pasta cooks perfectly and the flavors meld beautifully.
1 teaspoon Italian seasoning: Brings a fragrant mix of herbs that perfectly enhance the savory elements.
½ teaspoon garlic powder: Boosts the depth of flavor without overpowering the dish.
½ teaspoon onion powder: Adds a subtle sweetness and rounds out the seasoning.
¼ teaspoon red pepper flakes (optional): For a gentle kick of heat that livens up the casserole.
Salt and pepper, to taste: Essential seasonings that balance flavors and bring out the best in every ingredient.
2 cups shredded mozzarella cheese: Melts into a creamy, gooey layer that makes every bite irresistible.
Fresh parsley, chopped (optional): A splash of bright color and freshness as a garnish that adds a light herbal note.

How to Make Dump and Bake Meatball Casserole Recipe

Step 1: Preheat the Oven and Prepare Your Dish

Start by heating your oven to 425°F (220°C), which is perfect for cooking the pasta and meatballs together evenly. Lightly grease a 9×13 inch baking dish with cooking spray or butter to ensure nothing sticks and cleanup is a breeze.

Step 2: Combine Ingredients in the Baking Dish

This is where the magic of the Dump and Bake Meatball Casserole Recipe happens — simply toss your frozen meatballs, uncooked pasta, marinara sauce, water or broth, and all the seasonings right into the dish. Give everything a good stir until well combined. The uncooked pasta will soak up all those savory flavors as it bakes alongside the meatballs.

Step 3: Bake Covered

Cover the dish tightly with aluminum foil to trap moisture, which allows the pasta to cook gently and the meatballs to heat through. Pop it into your preheated oven for 30 minutes — this is the “set it and forget it” moment that makes this recipe so wonderfully simple.

Step 4: Add Cheese and Bake Again

Carefully remove the foil and give the casserole a quick stir to distribute everything evenly. Sprinkle the shredded mozzarella cheese over the top, which will melt into a bubbly, golden crust during the next baking phase. Return the dish to the oven, uncovered, and bake for another 10 to 15 minutes for that perfect cheesy finish.

Step 5: Let it Rest and Garnish

Once your casserole looks perfectly baked with melted cheese, take it out and let it cool just a few minutes. This resting time helps the casserole set slightly, making it easier to serve. If you have fresh parsley on hand, sprinkle some over the top for a pop of color and fresh flavor.

How to Serve Dump and Bake Meatball Casserole Recipe

Garnishes

A handful of freshly chopped parsley not only brightens up the presentation but also adds a subtle, herbaceous note. If you’re a fan of a little extra zing, a light drizzle of good quality olive oil or a sprinkle of grated Parmesan can also take this dish over the top.

Side Dishes

This casserole is hearty on its own, but pairing it with a crisp green salad with a tangy vinaigrette or some garlic roasted vegetables balances the meal and adds freshness. A crusty loaf of bread or garlic bread is another irresistible side that complements the saucy, cheesy pasta beautifully.

Creative Ways to Present

For a fun twist, serve individual portions in small ramekins to bring a personalized touch to the table. You can also layer the casserole into a deep dish and swirl in dollops of ricotta or dollops of pesto just before serving for extra flair. Either way, this Dump and Bake Meatball Casserole Recipe always looks as good as it tastes.

Make Ahead and Storage

Storing Leftovers

After enjoying your meal, store any leftovers in an airtight container in the refrigerator. The casserole keeps well for up to 3 to 4 days, making it an easy and delicious option for next-day lunches or dinners.

Freezing

If you want to save this Dump and Bake Meatball Casserole Recipe for later, it freezes beautifully. Place leftovers in a freezer-safe container or heavy-duty freezer bag, and it will keep well for up to 3 months. Just be sure to thaw it overnight in the fridge before reheating.

Reheating

To reheat, cover the casserole with foil and warm it in a 350°F (175°C) oven for about 20 minutes or until heated through. Alternatively, individual portions can be reheated in the microwave, but baking helps retain that fresh-from-the-oven texture.

FAQs

Can I use fresh meatballs instead of frozen?

Absolutely! If you have fresh meatballs on hand, feel free to use them. Just be mindful that cooking times may need a slight adjustment since fresh meatballs might cook faster than frozen ones.

What pasta works best for this casserole?

Penne, rotini, or other tubular or spiral pasta shapes are ideal because they hold onto the sauce well. Avoid very thin pastas like angel hair, which can become mushy during baking.

Can I make this recipe vegetarian?

Yes! Substitute vegetarian or plant-based meatballs for the traditional meat versions. The marinara sauce and cheese still bring tons of flavor for a satisfying vegetarian option.

Is it possible to prepare this casserole in advance?

Definitely. You can assemble the dish up to step 3, cover with foil, and refrigerate for a few hours before baking. Just add the cheese and bake when ready to serve for fresh, melty topping.

Can I add extra vegetables?

Sure thing! Diced bell peppers, mushrooms, or spinach can be stirred into the mixture before baking to sneak in some extra nutrients and texture without overpowering the classic flavors.
