Ingredients You’ll Need
- 1 pound frozen meatballs: These make the dish super convenient. You can choose beef, turkey, or even plant-based meatballs for a flexible approach.
- 1 onion, chopped: Adds depth of flavor and sweetness to the casserole.
- 2 cups uncooked pasta: I recommend a robust type like rotini or penne, which hold up well in the bake.
- 2 cups marinara sauce: Use your favorite jarred sauce or homemade for extra flavor.
- 1 tablespoon Italian seasoning: This brings an aromatic blend of herbs that pairs perfectly with the meatballs and sauce.
- 2 cups shredded mozzarella cheese: Melty and gooey, cheese is the centerpiece of this comforting dish.
- 1 cup water: Helps to cook the pasta while it bakes, contributing to the perfect texture.
How to Make Dump and Bake Meatball Casserole
- Preheat your oven to 375°F: This ensures your casserole bakes evenly and the flavors meld beautifully.
- Combine the ingredients: In a large mixing bowl, combine the frozen meatballs, chopped onion, uncooked pasta, marinara sauce, Italian seasoning, and water. Stir until everything is evenly coated.
- Transfer to a baking dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it out evenly.
- Cover with foil: This helps to trap steam and cook the pasta thoroughly while preventing the cheese from browning too quickly.
- Bake for 20 minutes: At this point, everything begins to heat through, and you can start to smell the deliciousness.
- Add cheese and bake again: Remove the foil, sprinkle the mozzarella cheese evenly on top, and return it to the oven uncovered. Bake for an additional 10–15 minutes or until the cheese is bubbly and golden.
Storing & Reheating
To store your Dump and Bake Meatball Casserole, allow it to cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. It can safely sit at room temperature for about two hours before being refrigerated for up to four days. For longer storage, you can freeze it for up to three months. When you’re ready to enjoy it again, just reheat in a preheated oven at 350°F until heated through, about 20–25 minutes. The texture might change slightly, but a sprinkle of fresh herbs can refresh the dish beautifully.
Chef’s Helpful Tips
- Avoid mushy pasta by sticking to the exact measurements and not overcooking beyond the recommended time.
- If using homemade meatballs, ensure they are cooked through before adding them to the casserole.
- For extra flavor, sauté the onions in a bit of olive oil before adding them to the mix.
- You can add vegetables like spinach or bell peppers into the mix for added nutrition and texture.
- Remember, leftovers are perfect for lunch the next day—just add some fresh herbs before reheating for a bright finish.
This recipe truly elevates the notion of comfort food and makes weeknight dinners an absolute breeze. It encourages creativity, too—feel free to experiment with your favorite ingredients or whatever you have on hand. Whether you customize it with different veggies or switch up the cheese, each version will be delightful in its way. I can’t wait for you to try it!

Recipe FAQs
Can I use fresh ingredients instead of frozen?
Absolutely! If you have fresh meatballs or cooked pasta on hand, feel free to substitute them in. Just make sure to adjust cooking times accordingly, as they may require less baking time.
What if I don’t have Italian seasoning?
No problem! You can mix your own with oregano, basil, and a pinch of garlic powder. Fresh herbs can also be used to brighten the dish—try fresh basil or parsley!
Can I make this casserole ahead of time?
Certainly! You can prepare the casserole up to the point of baking, cover it tightly, and store it in the refrigerator for up to 24 hours before baking. Just add a few minutes to the cooking time since it will be going in cold.
What is the best way to reheat leftovers?
The best way to reheat leftovers is in the oven to maintain the texture. Cover with foil and reheat at 350°F until warmed through, about 15-20 minutes. Alternatively, you can use the microwave, but be sure to add a splash of water to keep it moist.
