Dump and Bake Meatball Casserole Recipe

If you’re anything like me, busy weeknights call for easy, no-fuss dinners that still satisfy all the comfort food cravings. That’s exactly why I keep coming back to this Dump and Bake Meatball Casserole recipe. It’s the kind of meal that practically makes itself, which means more time to kick back and less time hovering over the stove.

What makes this casserole truly special is the simplicity: just toss a few ingredients into a baking dish, hit the oven, and dinner is served without the usual chopping, browning, or stirring. I love serving this when friends drop by unexpectedly or when I need a quick fix that still feels homemade and hearty.

Ingredients You’ll Need

These ingredients play perfectly off one another to keep the flavors balanced without any extra work. Plus, everything’s easy to find in the supermarket, and you can customize based on what you have on hand.

• Uncooked rotini pasta: I love rotini for casseroles because the twists trap the sauce and cheese beautifully.
• Marinara sauce: Picking a good-quality jar makes a noticeable difference here—your favorite brand or homemade works great.
• Water: This might seem odd, but it helps cook the pasta right in the casserole for that perfect texture.
• Fully-cooked miniature meatballs: Using pre-cooked meatballs keeps this recipe quick and easy, plus the cocktail-size bites spread evenly through the dish.
• Shredded mozzarella or Italian blend cheese: Melts perfectly and brings that gooey, comforting factor we all crave.
• Optional garnishes: A sprinkle of Parmesan and fresh herbs adds a lovely pop of flavor and color.

Variations

One of the things I love most about this Dump and Bake Meatball Casserole recipe is how easy it is to tweak! Make it your own, whether you prefer a spicy kick or a vegetarian twist.

• Spicy version: Adding red pepper flakes or swapping marinara for a spicy arrabbiata sauce really jazzes things up—I’ve done this for game day with great feedback.
• Vegetarian option: You can switch the meatballs for plant-based ones or roasted veggies like mushrooms and zucchini for a meat-free meal.
• Cheese blend: Mixing mozzarella with sharp cheddar or provolone gives it a richer, layered flavor I sometimes go for when I want to impress guests.
• Extra veggies: Toss in some diced bell peppers or spinach from your fridge for added nutrients and color without complicating the prep.

How to Make Dump and Bake Meatball Casserole Recipe

Step 1: Combine and Layer Everything

Start by preheating your oven to 350°F (175°C). Grab a 9×13-inch baking dish and dump in the uncooked rotini pasta, then pour the entire jar of marinara sauce and 3 cups of water right over the pasta. Don’t stir! Next, scatter the miniature meatballs evenly across the top. Layer on the shredded mozzarella cheese—this seals in all those tasty ingredients. This no-mess assembly is what makes this Dump and Bake Meatball Casserole recipe such a time saver.

Step 2: Bake Until Perfectly Cooked

Cover the dish tightly with foil to keep the moisture in and bake for about 55 minutes. I check at about 50 minutes to see if the pasta is tender and the sauce bubbly—if not, give it a few more minutes. Removing the foil the last 10 minutes helps the cheese brown up nicely, adding a lovely golden crust on top.

Step 3: Garnish and Serve

Once it’s out of the oven, sprinkle some freshly grated Parmesan cheese and a handful of chopped fresh herbs like basil or parsley for that extra flavor kick. Letting it rest for 5 minutes before serving helps everything set so it’s easier to plate and eat.

Garnishes

I’m a big fan of topping this casserole with a little extra Parmesan cheese—it melts right into the warm pasta and gives a salty, nutty boost. Fresh chopped basil or parsley is a must in my kitchen; it brightens up the rich tomato and cheesy flavors beautifully.

Side Dishes

Because this Dump and Bake Meatball Casserole recipe is pretty hearty on its own, I like to balance it with a crisp side salad or steamed green beans to keep things light. Garlic bread on the side is a family favorite when we’re craving something extra indulgent.

Creative Ways to Present

For special occasions, I’ve served this casserole in individual ramekins for cute single portions. It’s a fun way to personalize each plate and gives a cozy, comfort-food vibe. You could also drizzle a little balsamic glaze on top for a fancy twist that guests love.

Make Ahead and Storage

Storing Leftovers

Any leftovers can be stored in an airtight container in your fridge for up to 3 days. I’ve found the flavors really develop overnight, making the next-day meal even tastier. Just give it a quick stir when reheating to redistribute the sauce and cheese.

Freezing

I’ve frozen this casserole a few times by placing cooled leftovers in freezer-safe containers or bags. It freezes well for up to 2 months. When you’re ready to eat, thaw overnight in the fridge and reheat gently in the oven or microwave—just be prepared to add a little extra cheese or sauce to freshen it up.

Reheating

To reheat, I usually put a portion in a microwave-safe bowl and cover with a damp paper towel to keep it from drying out. Heat in 1-minute intervals, stirring in between. Alternatively, popping leftovers in a low oven (around 300°F) covered with foil keeps everything moist and melty.
