How to Make Dump and Bake Meatball Casserole

Instructions
- Preheat the Oven:
Preheat your oven to 375°F (190°C). - Prepare the Casserole Dish:
In a 9×13-inch baking dish, add the uncooked pasta and frozen meatballs. - Add the Sauce:
Pour the marinara sauce evenly over the pasta and meatballs. Add the water, ensuring the pasta is mostly covered, and stir to combine. - Season the Dish:
Sprinkle the dried Italian seasoning, garlic powder, and optional crushed red pepper flakes over the top of the casserole. Stir to combine the seasonings into the sauce. - Bake the Casserole:
Cover the baking dish tightly with aluminum foil and bake for 45 minutes. After 45 minutes, remove the foil, stir the casserole gently, and sprinkle the shredded mozzarella cheese and Parmesan cheese evenly on top. - Continue Baking:
Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the pasta is tender. - Garnish and Serve:
Once baked, remove the casserole from the oven and let it sit for 5 minutes before serving. Garnish with fresh parsley or basil for a burst of color and flavor.
Notes
- Substitutions:
- Use turkey or chicken meatballs for a lighter version.
- Swap out marinara sauce for Alfredo sauce or pesto for a different flavor profile.
- Add-ins:
- For extra veggies, stir in some chopped bell peppers, onions, or spinach before baking.
- You can also add some sliced pepperoni for a pizza-inspired version of this casserole.

Tips for the Recipe
- Make sure the pasta is fully submerged in the sauce and water mixture to ensure it cooks properly.
- If you prefer a crispier top, broil the casserole for a couple of minutes after baking.
FAQ
Can I use cooked meatballs instead of frozen?
Yes, you can! Just reduce the baking time slightly since the meatballs are already cooked. Make sure to stir the casserole halfway through to ensure even cooking.
Can I make this casserole ahead of time?
Absolutely! Assemble the casserole ahead of time, cover it, and refrigerate for up to 24 hours. When you’re ready to bake, just pop it in the oven and follow the baking instructions.
