Ingredients You’ll Need
Gathering these ingredients is a breeze, and each one plays an essential role to ensure your casserole bursts with delicious flavors and comforting textures. From the meaty goodness of the frozen meatballs to the creamy melt of mozzarella cheese, every element works in harmony to create that perfect baked pasta dish.
- Frozen fully-cooked meatballs (16 oz): Convenient and flavorful, they save prep time while adding hearty protein.
- Uncooked penne pasta (12 oz): The perfect pasta shape to hold sauce and cheese with every bite.
- Marinara sauce (3 cups): A rich, tangy base that infuses the casserole with classic Italian flavor.
- Water (3 cups): Helps the pasta cook evenly in the sauce during baking.
- Shredded mozzarella cheese (1 ½ cups): Creates a luscious, bubbling cheesy top layer.
- Grated Parmesan cheese (¼ cup): Adds a sharp, nutty depth that complements the mozzarella.
- Olive oil (1 tablespoon): Used to grease the dish to prevent sticking and add a subtle richness.
- Italian seasoning (1 teaspoon): A fragrant blend that brings herbs like oregano and basil to the forefront.
- Salt and pepper to taste: Essential for balancing and enhancing flavors.
- Optional fresh basil: Brightens the dish with a fresh, peppery aroma when garnished on top.
How to Make Dump and Bake Meatball Casserole Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 425 degrees Fahrenheit. Lightly grease a 9×13-inch baking dish with olive oil to keep everything from sticking and to add a subtle layer of flavor to the bottom of your casserole.
Step 2: Combine the Main Ingredients
In your prepared baking dish, pour in the uncooked penne pasta and scatter the frozen fully-cooked meatballs evenly. Add the marinara sauce and water, then sprinkle the Italian seasoning, salt, and pepper over the top. Give everything a good stir to make sure the pasta is submerged in the liquid, which is key to even cooking.
Step 3: Bake Covered
Cover your dish tightly with aluminum foil to trap steam, then bake for 35 minutes. This step cooks the pasta perfectly right in the sauce while warming those meatballs through to juicy tenderness.
Step 4: Add Cheese and Finish Baking
Remove the foil and stir the casserole gently. Now it’s time for the best part: sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top. Pop the dish back into the oven, uncovered, and let it bake for another 10 to 15 minutes. You’ll know it’s done when the cheese is melted and bubbly, and the pasta is tender.
Step 5: Let It Rest and Garnish
Once out of the oven, let your meatball casserole rest for five minutes to allow the flavors to settle and the casserole to firm up just a bit. For a fresh, herby finish, sprinkle chopped basil on top if you like.
How to Serve Dump and Bake Meatball Casserole Recipe

Garnishes
Fresh basil isn’t just a suggestion; it’s a flavor booster that lifts the entire dish with its bright aroma. You can also sprinkle extra Parmesan cheese or red pepper flakes for a little kick if you’re feeling adventurous.
Side Dishes
Serving this casserole with a simple green salad or garlic bread makes for a well-rounded meal that covers freshness, crunch, and hearty satisfaction. Roasted vegetables also complement this dish beautifully without stealing the spotlight.
Creative Ways to Present
For a special dinner, serve portions in individual ramekins to impress your guests. You might also top the casserole with sliced black olives or sun-dried tomatoes before baking to add color and texture that will wow your family and friends.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the casserole tightly with plastic wrap or foil and store in the refrigerator. Your leftovers will stay delicious for up to three days and reheat beautifully in the oven or microwave.
Freezing
This Dump and Bake Meatball Casserole Recipe freezes wonderfully. Assemble the casserole without the cheese topping, cover tightly with foil, and freeze for up to three months. When ready to eat, bake covered until heated through, then add cheese and finish baking as directed.
Reheating
For best results, reheat leftovers on a baking sheet in an oven preheated to 350 degrees Fahrenheit until warmed through and bubbly. This method keeps the pasta tender and the cheese perfectly melted, just like freshly made.
FAQs
Can I use fresh meatballs instead of frozen?
Absolutely! Fresh meatballs will add a homemade touch. Just make sure they are cooked through before combining in the casserole to ensure even baking.
What pasta works best for this recipe?
Penne is ideal, but you can substitute with other short pasta shapes like rigatoni, ziti, or rotini. These shapes hold sauce well and fit perfectly in a casserole dish.
Is it okay to add vegetables to the casserole?
Yes! Adding veggies like bell peppers, mushrooms, or spinach can make the dish even more nutritious and colorful. Just be sure to chop them small so they cook through during baking.
How can I make this recipe spicier?
Try using spicy meatballs or adding red pepper flakes to the sauce. A dash of hot sauce stirred into the marinara also works wonders for a fiery kick.
Can I prepare this recipe ahead of time?
You can assemble the casserole a few hours ahead and refrigerate it, but bake it fresh when you’re ready to enjoy to keep the pasta texture perfect.
