Ingredients You’ll Need

To make this Dump-and-Bake Meatball Casserole Recipe come together so seamlessly, you’ll want to have these few pantry staples on hand. Each ingredient plays a big part in keeping it simple but tasty — and I always recommend grabbing good-quality pasta sauce for the best flavor.

• Frozen meatballs: Using frozen meatballs cuts down prep time, and they cook perfectly straight from frozen in the casserole.
• Pasta sauce: A flavorful jarred marinara or tomato basil sauce is ideal; it infuses everything with rich, tangy goodness.
• Water: This helps the pasta cook in the casserole so you don’t have to boil it separately—easy cleanup!
• Uncooked pasta: Penne or rigatoni work best here because their shape holds onto the sauce and meatballs nicely.
• Shredded mozzarella cheese: The gooey cheese layer is essential for that cozy casserole vibe.
• Grated Parmesan cheese: Just a little sprinkle adds a delicious, sharp finish.
• Optional fresh basil or parsley: A fresh sprinkle on top brightens the whole dish with a pop of color and aroma.

Variations

This Dump-and-Bake Meatball Casserole Recipe is so flexible—you can easily tweak it to suit your taste or dietary needs. I’m a big fan of getting creative here, so feel free to make it your own!

• Make it spicy: Add a pinch of red pepper flakes or a drizzle of hot sauce to the sauce before baking. I tried this once for a game night and it was a hit with spice lovers!
• Vegetarian option: Swap out the meatballs for your favorite plant-based meatballs or roasted veggies for a lighter twist.
• Extra veggies: Toss in some chopped bell peppers or mushrooms directly into the sauce—adds texture and a nutritional boost.
• Cheese swap: Use provolone or a mix of mozzarella and cheddar for a different melt and flavor profile.

How to Make Dump-and-Bake Meatball Casserole Recipe

Step 1: Prepare Your Dish

Start by grabbing a 9×13-inch baking dish—that’s the perfect size for this recipe. No need to grease it, since the sauce will keep everything moist. Then, spread the frozen meatballs evenly across the bottom. What I’ve found helpful is giving them a little space so they heat evenly without sticking together.

Step 2: Pour in Sauce, Water, and Pasta

Next, pour the entire jar of pasta sauce over the meatballs, making sure they’re fully covered. Add the cup of water and then evenly scatter the uncooked pasta right on top. The water and sauce together help the pasta cook perfectly during baking, so don’t skip this part!

Step 3: Cover and Bake

Cover the casserole tightly with foil—it traps the steam and ensures the pasta cooks tender. Pop it in a preheated oven at 375°F (190°C) for about 45 minutes. Halfway through, give it a gentle stir if you like, but I usually leave it be and it comes out great every time.

Step 4: Add Cheese and Finish Baking

After 45 minutes, carefully take off the foil and sprinkle the mozzarella and Parmesan evenly over the top. Then return it to the oven uncovered for another 10-15 minutes until the cheese is melted and bubbly with golden spots. Watching that cheese bubble up is one of my favorite moments!

How to Serve Dump-and-Bake Meatball Casserole Recipe

Garnishes

I always top mine with fresh basil or parsley right before serving for that fresh, herby punch. It brightens the richness of the cheese and sauce and makes the dish look pretty enough to impress friends or family at the table.

Side Dishes

For sides, I like to keep it simple—a crisp green salad or some garlic bread pairs beautifully with this casserole. Sometimes, I make roasted Brussels sprouts or steamed green beans for a little extra crunch and veggies.

Creative Ways to Present

If I’m serving this for a potluck or a cozy dinner party, I like to bake it in individual ramekins for personal portions—it’s a fun twist that feels special and cuts down on the serving stress. Another idea is to layer it with extra cheese or sprinkle toasted breadcrumbs on top for a crunchy finish.

Make Ahead and Storage

Storing Leftovers

After dinner, I let any leftovers cool to room temperature, then store them in an airtight container in the fridge. The casserole holds up well for 3-4 days, which is perfect for those busy follow-up lunches or quick dinners.

Freezing

I’ve frozen this Dump-and-Bake Meatball Casserole Recipe a couple of times with great results. Just transfer cooled casserole into a freezer-safe container, cover tightly, and freeze for up to 3 months. When you’re ready, thaw it overnight in the fridge before reheating.

Reheating

To reheat, I prefer warming it in the oven at 350°F (175°C) until heated through. This keeps the pasta from getting mushy and revives the cheese topping nicely. If you’re in a hurry, the microwave works too—just cover loosely and heat in short bursts, stirring in between.
