Ingredients
Meatball Casserole
- 1 lb dried pasta
- 28 oz bag frozen meatballs
- 24 oz marinara sauce
- 3 cups low-sodium beef broth
- 1 teaspoon Italian seasoning
- ¾ teaspoon garlic powder
- ¼ teaspoon onion powder
- ¼ teaspoon red pepper flakes
Optional Toppings
- 1–2 cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- Fresh parsley or basil, chopped
- Extra Italian seasoning
- Red pepper flakes, to taste
Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a large oven-safe casserole dish or baking dish.
A deep 9 × 13-inch baking dish works well for this recipe.
2. Combine the Sauce
In a large bowl, combine the marinara sauce, beef broth, Italian seasoning, garlic powder, onion powder, and red pepper flakes.
Stir well until the seasonings are evenly distributed.
The beef broth helps provide enough liquid for the dried pasta to cook directly in the casserole while adding extra savory flavor.
3. Assemble the Casserole
Add the dried pasta to the prepared baking dish.
Arrange the frozen meatballs evenly over the pasta.
Pour the seasoned marinara mixture over everything.
Gently stir or toss the ingredients as much as possible so the pasta is coated with sauce and the liquid is distributed throughout the dish.
Make sure the pasta is mostly submerged in the liquid. This is important for even cooking.
4. Cover and Bake
Cover the baking dish tightly with aluminum foil.
Place it in the preheated oven and bake for approximately 25–30 minutes.
Keeping the casserole covered during the first stage traps steam and helps the dried pasta cook properly.
5. Stir and Check
Carefully remove the foil—the steam will be very hot.
Give the casserole a thorough stir, making sure the pasta is evenly distributed and coated with sauce.
Check the pasta for doneness.
If the pasta is still firm and the casserole appears dry, add a small amount of additional broth or water, cover again, and continue baking.
6. Add the Cheese
Once the pasta is nearly tender, remove the foil.
If using, sprinkle the top generously with shredded mozzarella and Parmesan cheese.
Return the uncovered casserole to the oven.
7. Finish Baking
Bake for another 8–12 minutes, or until:
- The pasta is completely tender.
- The sauce is bubbling.
- The meatballs are heated through.
- The cheese is melted and golden in spots.
For a more deeply browned cheese topping, switch the oven to broil for the final 1–2 minutes, watching carefully so it doesn’t burn.
8. Rest Before Serving
Remove the casserole from the oven and allow it to rest for approximately 5–10 minutes.
This gives the sauce time to thicken and makes the casserole easier to serve.
9. Garnish and Serve
Finish with freshly chopped parsley or basil and an optional sprinkle of Parmesan cheese.
Serve hot with garlic bread, a simple green salad, or roasted vegetables.
Chef’s Tips
Don’t Skip the Foil
Covering the casserole helps trap steam so the dried pasta can cook properly.
Keep the Pasta Submerged
Any exposed pasta may remain undercooked. Stir the ingredients before baking and make sure the pasta is well coated with the sauce and broth.
Check Before Adding Cheese
Test the pasta before adding the cheese topping. If it’s still too firm, continue cooking before finishing the casserole.
Adjust the Spice
The red pepper flakes add a subtle kick. Increase the amount for a spicier casserole or leave them out for a milder family-friendly version.
Let It Rest
A short resting period allows the sauce to thicken and the flavors to settle.
Cheese Topping Options
For an extra cheesy casserole, use a combination of:
- Mozzarella
- Parmesan
- Provolone
- Italian blend cheese
- Fontina
Mozzarella provides a stretchy, melty topping while Parmesan adds a salty, savory finish.
Variations
Creamy Meatball Casserole
Stir a small amount of cream cheese, heavy cream, or ricotta into the sauce before baking for a creamy version.
Vegetable Meatball Casserole
Add chopped bell peppers, zucchini, mushrooms, spinach, or onions for extra vegetables.
Spicy Meatball Casserole
Increase the red pepper flakes and add a little crushed chili or spicy Italian sausage.
Chicken Meatballs
Swap the beef meatballs for frozen chicken or turkey meatballs for a lighter variation.
Serving Suggestions
Serve this hearty casserole with:
- Garlic bread
- Cheesy bread
- Caesar salad
- Simple green salad
- Roasted broccoli
- Steamed green beans
- Garlic butter vegetables
A sprinkle of fresh basil or parsley adds a bright finish to the rich marinara sauce.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerator: Up to 3–4 days.
Because the pasta absorbs sauce as it sits, you may want to add a splash of broth or water when reheating.
Reheating
Microwave
Heat individual portions in 30–60 second intervals, stirring between intervals, until hot.
Oven
Place the casserole in an oven-safe dish, cover with foil, and reheat at 350°F (175°C) until warmed through.
Add a splash of broth or water if the pasta has become dry.
Freezing
For best texture, freeze the casserole after it has cooled completely.
Store in an airtight freezer-safe container for up to 2–3 months.
Thaw overnight in the refrigerator before reheating.
Recipe Summary
This Easy Meatball Casserole is a comforting one-dish meal made with dried pasta, frozen meatballs, marinara sauce, savory beef broth, and Italian seasonings. Everything bakes together until the pasta is tender, the meatballs are hot and juicy, and the sauce is rich and flavorful.
