Dump and Bake Meatball Casserole Ingredients

Here's what you'll need to make this quick and easy Dump and Bake Meatball Casserole.

See Recipe Card Below This Post For Ingredient Quantities

Marinara sauce: This is the base of your sauce and gives the dish all that rich tomato flavor. Any jarred marinara you like will work beautifully here.
Water: Thins out the sauce so there's enough liquid for the pasta to cook in. Don't skip this or your noodles won't soften properly.
Italian seasoning: Adds that classic herb blend of basil, oregano, and thyme. It makes the whole dish smell like an Italian kitchen.
Kosher salt: Seasons the sauce and helps bring out all the other flavors.
Garlic powder: Gives a subtle garlicky warmth without having to chop fresh garlic.
Onion powder: Adds a hint of sweetness and depth to the sauce.
Uncooked rotini pasta: Cooks right in the casserole, soaking up all that saucy goodness. Rotini holds onto the sauce nicely with its spiral shape.
Frozen fully-cooked miniature Italian-style meatballs, thawed: These little cocktail-size meatballs are perfectly portioned and just need to heat through. Thawing them first helps everything cook evenly.
Shredded mozzarella cheese or Italian blend cheese: Melts into a gooey, golden layer on top. Use whichever cheese you have on hand.
Optional garnish - Parmesan cheese and fresh herbs: A sprinkle of Parmesan and some chopped basil or parsley makes it look (and taste) restaurant-worthy.

How to Make Dump and Bake Meatball Casserole

Making this Dump and Bake Meatball Casserole is as simple as it gets.

Preheat oven: Preheat your oven to 425°F. Spray a 9 x 13-inch baking dish with nonstick cooking spray so nothing sticks.

Mix the sauce: In the prepared dish, whisk together the marinara sauce, water, Italian seasoning, kosher salt, garlic powder, and onion powder until everything is blended and smooth.

Add pasta and meatballs: Add the uncooked pasta and thawed meatballs to the dish. Stir everything together, spreading it evenly in the sauce. Use a spoon to gently press the noodles down to make sure they're submerged in the liquid as much as possible. This helps them cook through.

Bake covered: Cover the dish tightly with aluminum foil and bake for 35 minutes. The foil traps the steam, which cooks the pasta.

Stir and check pasta: Remove the foil and stir gently. Check the pasta for doneness by tasting a piece. If it's still too firm, cover the dish again and bake for an additional 5 to 10 minutes, then check once more.

Add cheese: Sprinkle mozzarella cheese evenly over the top. Bake uncovered for another 5 to 10 minutes, or until the cheese is melted and bubbly and the pasta is tender.

Garnish and serve: Let it cool for a few minutes, then garnish with Parmesan cheese and fresh herbs if you like. Serve it up warm and enjoy.

Substitutions and Variations

Use different pasta shapes. Penne, rigatoni, or even shells work just as well as rotini. Just stick with a sturdy pasta that can hold up to baking.

Swap the meatballs. Turkey meatballs, chicken meatballs, or even plant-based meatballs are great alternatives if you want to change things up.

Add vegetables. Toss in some chopped bell peppers, spinach, or zucchini when you add the pasta for extra nutrition and color.

Make it spicier. Stir in some red pepper flakes or use a spicy marinara sauce if you like a little kick.

Try a different cheese. Provolone, fontina, or a sharp cheddar would all be delicious on top instead of mozzarella.

Serving Suggestions

This Dump and Bake Meatball Casserole is hearty enough to stand on its own, but here are a few ideas to round out the meal.

Garlic bread: Warm, buttery garlic bread is perfect for soaking up any extra sauce on your plate.

Simple green salad: A crisp salad with a light vinaigrette balances out all that cheesy richness.

Roasted vegetables: Broccoli, green beans, or roasted zucchini make a nice side that adds some color to your plate.

Pair it with Candied Yams: If you're feeding a crowd or want a sweet side, candied yams are a cozy addition.

Expert Tips

Make sure the pasta is submerged. When you add the pasta and meatballs, really press those noodles down into the sauce. If they're sticking up out of the liquid, they won't cook through properly.

Don't skip thawing the meatballs. Frozen meatballs will release too much moisture and throw off the cooking time. Let them sit at room temperature for about 30 minutes or thaw them in the fridge overnight.

Check the pasta before adding cheese. Every oven is a little different, and some pasta brands cook faster than others. Taste a noodle before you add the cheese to make sure it's tender enough.

Let it rest for a few minutes. When you pull the Dump and Bake Meatball Casserole out of the oven, give it 5 minutes to set before serving. This helps the sauce thicken up and makes it easier to scoop out neat portions.

FAQ

How do you make a simple meatball casserole?

Whisk together marinara, water, and seasonings in a baking dish, then add uncooked pasta and thawed meatballs. Cover and bake until the pasta is tender, then top with cheese and bake uncovered until melted. My favorite tip is to press the pasta down into the sauce so it cooks evenly.

Can I use frozen meatballs for a casserole?

Yes, but make sure to thaw them first. Frozen meatballs will release extra moisture as they cook, which can water down your sauce and affect the texture. Just let them sit out for about 30 minutes or thaw them in the fridge overnight.

What is the best pasta for a meatball casserole?

Rotini, penne, or rigatoni work best because their shapes hold onto the sauce and stay firm during baking. I like rotini because the spirals catch all the cheesy, saucy goodness. Avoid delicate pastas like angel hair, they'll turn mushy.

How do you make a meatball pasta bake?

Combine uncooked pasta, thawed meatballs, marinara sauce, and water in a baking dish. Bake covered until the pasta is tender, then top with cheese and bake uncovered until bubbly. The key is using enough liquid so the pasta can cook right in the dish without being boiled first.
