Get ready for the ultimate comfort food: Dump and Bake Meatball Casserole. With zero fuss and all the flavor, this dish is your answer to weeknights when time is tight but cravings are real. It comes together in one dish—just layer, bake, and let the oven do the work.

What makes this casserole magical is how it transforms basic ingredients into something that feels like a warm hug. Juicy meatballs, tender pasta, rich marinara, and bubbling cheese join forces to deliver a dinner that’s as satisfying as it is easy. Whether you’re feeding a hungry family or meal prepping for the week, this one-pan wonder has your back.

What Kind of Pasta Should I Use?

Since this is a no-boil recipe, go for short pasta that cooks evenly without turning to mush. Rotini, penne, or rigatoni are top choices because they hold sauce beautifully and cook well in the oven. Avoid delicate shapes like angel hair or shells.

Ingredients for the Dump and Bake Meatball Casserole

• Frozen meatballs: These are the time-saver hero here. No need to thaw—they’ll cook perfectly in the sauce.
• Marinara sauce: Use a good-quality jarred version or homemade if you have some on hand. This brings the depth and body to the dish.
• Uncooked rotini pasta: Sturdy and spiral-shaped, it grabs onto all that cheesy, saucy goodness.
• Water or broth: Adds the needed liquid for the pasta to cook during baking.
• Shredded mozzarella cheese: Melted, gooey, and irresistible. It crowns the casserole beautifully.
• Parmesan cheese: For a touch of salty depth and golden top.
• Italian seasoning: Rounds out the flavor with classic herbs.

How To Make the Dump and Bake Meatball Casserole

Step 1: Prep the Dish

Preheat your oven to 425°F. Grease a large 9×13-inch baking dish to prevent sticking.

Step 2: Mix and Layer

In your baking dish, combine the uncooked pasta, marinara sauce, water (or broth), and Italian seasoning. Stir to coat all the noodles. Nestle in the frozen meatballs evenly throughout the dish.

Step 3: Cover and Bake

Cover the dish tightly with foil and bake for 35 minutes. This traps steam to help the pasta cook perfectly.

Step 4: Uncover and Add Cheese

After 35 minutes, remove the foil, give the pasta a gentle stir if needed, and sprinkle the mozzarella and Parmesan evenly on top. Return to the oven uncovered and bake for an additional 10-15 minutes until the cheese is melted and bubbly.

Step 5: Garnish and Serve

Let the casserole rest for 5 minutes before serving. Sprinkle with fresh parsley or red pepper flakes for extra flair.
