Ingredients Dump-and-Bake Meatball Casserole

This ingredient list is short, sweet, and totally manageable. You may even have most of it on hand already:

Frozen Meatballs – 1 pound. Use your favorite brand—beef, turkey, or even plant-based.

Pasta Sauce – One 24-ounce jar of your favorite marinara or tomato basil variety. Homemade works too.

Water – 1 cup. Helps the pasta cook evenly and keeps the dish from drying out.

Uncooked Pasta – 2 cups of something hearty like penne or rigatoni. Avoid delicate pastas; they might get mushy.

Shredded Mozzarella Cheese – 1 cup for melty, cheesy goodness on top.

Grated Parmesan Cheese – 1/4 cup for that salty, savory finish.

Fresh Basil or Parsley (optional) – A sprinkle of green to make it look fancy without the work.

How to Make Dump-and-Bake Meatball Casserole

The name says it all! Just dump it, bake it, and you’re done. Here’s the play-by-play:

Preheat the Oven: Set your oven to 425°F (220°C). Grease a 9×13-inch baking dish.
Dump It All In: Add uncooked pasta, frozen meatballs, pasta sauce, and water to the dish. Stir everything gently to combine and evenly coat the pasta and meatballs.
Cover and Bake: Cover the dish tightly with aluminum foil and bake for 35 minutes.
Add the Cheese: Remove the foil and sprinkle mozzarella and Parmesan over the top.
Bake Again: Return to the oven, uncovered, and bake for another 10–15 minutes, until the cheese is melted and bubbly and the pasta is tender.
Garnish and Serve: Let cool for 5 minutes. Top with chopped fresh parsley or basil if using. Serve warm with a green salad and maybe some garlic bread.

Equipment Needed

9×13-inch baking dish
Aluminum foil
Mixing spoon or spatula
Measuring cups

Variations To Try

Add veggies: Toss in a cup of frozen spinach or some chopped bell peppers before baking.
Go spicy: Use spicy marinara and add red pepper flakes for a kick.
Make it creamy: Stir in a few spoonfuls of ricotta or a splash of heavy cream before baking.
Use different pasta: Shells, rotini, or ziti work great. Just make sure it’s uncooked and not too delicate.
Try a different cheese: Fontina, provolone, or a blend works beautifully on top.

Serving Suggestions

Pair with a fresh Caesar salad or a crisp garden salad.
Add a side of garlic knots or toasted baguette for dipping.
Serve with roasted vegetables for a well-rounded meal.
Great as leftovers the next day—just reheat in the microwave or oven.

Tips for Success

Grease your dish well so nothing sticks.
Don’t skip the foil cover in the first bake—it traps steam and helps cook the pasta.
Give it a good stir before baking to make sure pasta isn’t clumping.
Let it rest a few minutes after baking so everything sets up nicely.
Use high-quality sauce for the best flavor with minimal effort.

FAQs about Dump-and-Bake Meatball Casserole
