What makes this casserole truly special is how you literally just “dump” everything into one dish, bake it, and end up with tender meatballs, perfectly cooked pasta, and melty cheese all in one – no stirring required.

I especially love making this Dump-and-Bake Meatball Casserole Recipe on busy weeknights or when unexpected guests drop by.

Ingredients You’ll Need

The beauty of this recipe lies in its simplicity. Every ingredient plays a key role to create harmony between the tender meatballs, savory tomato sauce, and perfectly cooked pasta right in your casserole dish.

• Frozen meatballs: Using frozen meatballs keeps prep quick without sacrificing flavor. Choose your favorite brand or homemade frozen balls for the best results.
• Pasta sauce (24 ounces): I recommend a good-quality marinara or your favorite jarred sauce to keep the flavor rich and authentic.
• Water: This helps the pasta cook perfectly inside the sauce without drying out the casserole.
• Uncooked pasta: Penne or rigatoni work best since their shape holds the sauce well, but feel free to use whatever you have on hand.
• Shredded mozzarella cheese: Essential for that gooey, melty top layer everyone loves.
• Grated Parmesan cheese: Adds a punch of saltiness and depth when sprinkled over cheese.
• Fresh basil or parsley (optional): A quick fresh garnish adds color and brightness to the dish before serving.

Variations

I’m all about making this Dump-and-Bake Meatball Casserole Recipe your own. Whether it’s swapping ingredients for dietary needs or just jazzing it up a bit, you can customize to match your taste and what’s in your kitchen.

• Vegetarian variation: I sometimes use plant-based meatballs or chickpea “meatballs” to keep things meat-free, and it’s always a hit with veggie lovers.
• Spicy twist: Adding some red pepper flakes or using a spicy arrabbiata sauce gives it a nice kick that my family enjoys on colder nights.
• Cheesy overload: Swap in a mix of mozzarella, provolone, and even a little smoked gouda for a decadent, gooey top.
• Seasonal veggies: Throw in some chopped bell peppers, mushrooms, or zucchini for extra veggies without adding complexity.

How to Make Dump-and-Bake Meatball Casserole Recipe

Step 1: Assemble Your Ingredients

Start by grabbing a large casserole dish. No need to pre-cook the pasta since everything will bake together. I like to toss the frozen meatballs straight into the dish, followed by uncooked pasta, your chosen pasta sauce, and a cup of water. This water is key—it helps the pasta cook through evenly and absorb some of that delicious sauce.

Step 2: Stir and Spread Evenly

Give everything a good stir so the sauce coats the pasta and meatballs well. It’s okay if some meatballs poke out on top—that’s where they’ll get that nice cooked texture. Spread the mixture out evenly in the dish, so nothing clumps up, ensuring even cooking.

Step 3: Add Cheese and Bake

Sprinkle your shredded mozzarella and Parmesan cheese evenly over the top—this is what transforms the casserole into a melty masterpiece. Pop it in a preheated oven at 375°F (190°C) for about 45-50 minutes. You’ll want it bubbly and golden on top, with the pasta tender and meatballs heated through. If you notice the cheese browning too quickly, tent some foil over the dish halfway through baking.

How to Serve Dump-and-Bake Meatball Casserole Recipe

Garnishes

Once it’s out of the oven, I love adding a handful of fresh basil leaves or chopped parsley right on top for a pop of color and fresh flavor. A sprinkle of extra Parmesan cheese never hurts, either. These little touches really elevate the presentation and taste.

Side Dishes

You really don’t need much on the side since this casserole is so satisfying, but a simple green salad or steamed broccoli pairs beautifully to add some freshness and crunch. Sometimes I serve it alongside garlic bread to sop up any leftover sauce—it’s always a winner!

Creative Ways to Present

For special occasions, I’ve tried layering the meatballs and pasta sauce with slices of roasted eggplant or zucchini for a veggie-packed twist. Or even baking this casserole in individual ramekins for a charming, personalized touch that’s perfect for dinner parties.

Make Ahead and Storage

Storing Leftovers

I always cover any leftover Dump-and-Bake Meatball Casserole Recipe with foil or airtight wrap and store it in the fridge for up to 3 days. The flavors actually deepen overnight, so leftovers can be even better! Just be sure to cool it fully before refrigerating to keep it fresh.

Freezing

If you want to prep ahead, this casserole freezes really well. I usually bake it fully first, then portion it into freezer-safe containers. When I need it, I thaw overnight in the fridge and reheat gently in the oven. Freezing before baking is possible, but I find the texture better if baked first.

Reheating

To reheat, I pop leftovers in the oven at 350°F (175°C) covered with foil to keep moisture in, warming for 15-20 minutes until bubbly. You can also microwave single servings covered loosely, but the oven method keeps cheese melty and pasta tender without drying out.
