Ingredients You’ll Need
This recipe calls for a handful of straightforward ingredients that come together effortlessly, each playing a crucial role in building a delicious, comforting casserole. From the pasta that holds everything together to the melty cheese that crowns the dish, every element is essential.
- Rotini pasta (16 oz): Its twisted shape captures sauce perfectly, ensuring every bite is packed with flavor.
- Water (3 cups): Hydrates the pasta directly in the baking dish, making it superbly tender without boiling separately.
- Pasta sauce (24 oz jar): Provides the rich, tangy tomato base that melds all the ingredients beautifully.
- Kosher salt (1 teaspoon): Elevates all the flavors, ensuring the dish isn’t bland.
- Frozen precooked meatballs (14 oz, thawed): Adds hearty, savory protein without extra prep time.
- Shredded mozzarella cheese (2 cups): Melts to gooey perfection, creating a luscious, bubbly topping.
- Grated Parmesan cheese or chopped fresh parsley (optional): Offers a punch of brightness or nuttiness as a finishing touch.
How to Make Dump and Bake Meatball Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 425°F (218°C). This high heat ensures our casserole cooks evenly and the cheese melts into a perfect bubbly topping. While the oven warms up, prepare your baking dish by lightly spraying a 9×13 inch pan with cooking spray. This little step makes cleanup easier later and prevents the casserole from sticking.
Step 2: Assemble the Casserole
Now here’s the fun part where the “dump” in our Dump and Bake Meatball Casserole Recipe really lives up to its name. Into your baking dish, pour the uncooked rotini pasta. Pour over the water and add the pasta sauce right on top—no cooking needed ahead of time. Scatter your thawed meatballs across, and season everything with kosher salt. Give the mixture a gentle stir just to combine, ensuring all ingredients are evenly dispersed.
Step 3: Bake Initial Stage
Cover the whole dish tightly with aluminum foil and pop it into the preheated oven. Bake it for 35 minutes, but here’s a little secret—about halfway through, remove the foil carefully and give the mixture a good stir. This keeps the pasta from sticking together and ensures everything cooks evenly. Replace the foil and let it continue baking for the rest of the time.
Step 4: Add Cheese and Finish Baking
After the initial baking, remove the foil and give the casserole one last stir. Sprinkle the 2 cups of shredded mozzarella cheese generously over the top. Return the dish to the oven, uncovered, and bake for another 5 to 8 minutes until the cheese melts fully and turns lightly bubbly. This final step creates that irresistible golden layer everyone raves about.
Step 5: Serve
Once out of the oven, let your casserole cool for a few minutes—this helps it set up perfectly for serving. If you want, garnish with freshly grated Parmesan cheese or a sprinkle of chopped fresh parsley to add a flavorful and colorful finishing touch. Serve while warm and watch your friends and family dive in happily!
How to Serve Dump and Bake Meatball Casserole Recipe

Garnishes
A quick sprinkle of grated Parmesan cheese adds depth and a nutty richness that complements the mozzarella beautifully. Alternatively, freshly chopped parsley brightens every bite and adds a pop of green to make the dish look as delightful as it tastes.
Side Dishes
Since this casserole is quite hearty, lighter side dishes work wonderfully alongside it. A crisp green salad with a tangy vinaigrette cuts through the richness, or roasted vegetables like broccoli and zucchini can add some fresh texture and color to your plate.
Creative Ways to Present
For a fun twist, serve this casserole family-style straight from the baking dish at the table—it encourages everyone to dig in and share. You can also portion it into individual ramekins for a neat, personalized presentation perfect for casual dinner parties.
Make Ahead and Storage
Storing Leftovers
Leftover Dump and Bake Meatball Casserole Recipe keeps well in the fridge for up to 3 days. Store it in an airtight container to preserve freshness, and the flavors will only deepen overnight, making your next meal just as delightful.
Freezing
If you want to save time on a future busy day, assemble the casserole as directed but don’t bake it yet. Cover tightly with foil and freeze for up to 2 months. When ready, bake it straight from frozen, adding some extra minutes to the cooking time.
Reheating
Reheat individual portions in the microwave until warmed through and the cheese is melty again. For larger servings, cover with foil and warm in a 350°F oven until hot, usually about 20 minutes.
FAQs
Can I use fresh meatballs instead of frozen precooked ones?
Yes, but if using fresh meatballs, it’s best to cook them first before adding to the casserole to ensure they’re fully cooked through.
What if I don’t have rotini pasta? Can I use something else?
Absolutely! Most short pasta shapes like penne or rigatoni work well in this recipe and hold sauce beautifully.
Is it possible to make this casserole gluten-free?
Definitely—just swap out the regular rotini for a gluten-free pasta, and make sure your pasta sauce and meatballs are gluten-free as well.
Can I add vegetables to the Dump and Bake Meatball Casserole Recipe?
Yes! Adding diced bell peppers, mushrooms, or spinach before baking can add extra flavor and nutrition without complicating the recipe.
How spicy is this dish? Can I adjust the heat?
This casserole is mild by default but feel free to add red pepper flakes or a splash of hot sauce to the pasta sauce if you like some heat.
