If you love simple comfort food dinners that require almost no prep, this Dump & Bake Meatball Casserole will quickly become a favorite in your kitchen. It’s one of those recipes that feels like magic — you simply combine everything in one dish, pop it in the oven, and let it cook itself into a bubbly, cheesy, pasta-filled masterpiece.
The pasta cooks directly in the marinara sauce while the meatballs warm through and release their savory flavor into the dish. As everything bakes together, the sauce thickens and the pasta becomes tender. The final touch is a generous layer of melty cheese that turns golden and bubbly in the oven.
This recipe is perfect for busy weeknights, family dinners, potlucks, or anytime you want a hearty meal without spending a lot of time in the kitchen.

How to Make Dump & Bake Meatball Casserole
Step 1 – Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a 9×13 baking dish.
Step 2 – Add the Pasta and Sauce
Add the uncooked pasta to the baking dish.
Pour in the marinara sauce and water (or broth).
Stir everything together so the pasta is fully coated and mostly submerged in the sauce.
Step 3 – Add the Meatballs
Place the frozen meatballs evenly throughout the dish.
Sprinkle with:
- Italian seasoning
- garlic powder
- onion powder
- salt and pepper
Gently stir once more.
Step 4 – Bake Covered
Cover the baking dish tightly with foil.
Bake for 35 minutes.
This allows the pasta to cook in the sauce.
Step 5 – Add the Cheese
Remove the foil and stir the casserole gently.
Sprinkle mozzarella and parmesan cheese evenly on top.
Step 6 – Bake Until Bubbly
Return the casserole to the oven uncovered for 10–15 minutes, until the cheese is melted, golden, and bubbly.
Step 7 – Serve
Let the casserole rest for 5 minutes.
Garnish with chopped parsley or basil and serve warm.
Tips for the Best Meatball Casserole
Use a thick marinara sauce so the pasta absorbs flavor while cooking.
Make sure the pasta is mostly submerged in liquid before baking.
If the pasta still feels firm, add ¼ cup hot water, cover, and bake another 5–10 minutes.
