Simple Ingredients

Here’s a quick-reference check list of the common ingredients you’ll need for this family favorite recipe:

  • Frozen meatballs – look for an Italian meatballs from the frozen foods section of your grocery store.
  • Penne rigate pasta – penne works well for this recipe, however, you could substitute most other medium-sized pastas, like rotini, rigatoni, ziti or gemelli.
  • Pasta sauce – a simple marinara sauce or tomato sauce works well for this recipe, however, feel free to choose a flavor that suits your tastes. If you like a robust sauce, add another 1-2 teaspoons of dry Italian seasoning or garlic powder or onion powder. Or to be a big hit, all of them.
  • Water – water is needed to help the pasta bake and become tender.
  • Shredded mozzarella cheese – you can use either regular or part-skim mozzarella shredded cheese for this recipe. Next time I’ll do a mix of cheese and more cheese.

How to Make a Dump and Bake Meatball Casserole

One of my favorite parts of this recipe is that it’s super quick and easy. check out exactly how to make it below.

  1. Add pasta and water. In a casserole dish or 9 x 13” pan coated with cooking spray, add the uncooked pasta, water and pasta sauce. Stir these together well.
  2. Defrost meatballs. In your microwave, using the defrost setting, defrost the meatballs. Once the meatballs are no longer frozen, add them to the pasta and sauce mixture. If they aren’t defrosted, they won’t have enough time to cook, but make sure they also aren’t hot, otherwise they won’t be juicy meatballs.
  3. Cover and bake. Cover the baking dish with foil and bake the casserole. About half way through baking, stir the mixture to ensure the pasta and meatballs bake evenly.
  1. Top with cheese and bake. Add the shredded mozzarella cheese to the top of the casserole and bake until the cheese is completely melted and light golden brown.

  1. Enjoy. Serve with your favorite side salad or vegetables. And I like to add more cheese, specifically freshly shredded parmesan cheese and a fresh hand torn pieces of fresh basil from the garden.

It is important to cover the baking dish with foil when baking. This will keep the steam in the baking dish and allow the pasta to cook evenly and become tender. If baked uncovered, the pasta will become dry, tough, and only partially cooked.

    This turned out great! The only thing I changed was used 1/2 Alfredo and 1/2 marinara. Will definitely be making this regularly!

    I am always looking for an easy yet yummy weeknight dinner idea for my family. I love that this dish involves minimal prep work and is done in under an hour.

    Seriously the easiest weeknight recipe ever. We always have homemade meatballs in the freezer (my husband is Italian so that’s the only kind he will eat) and I love not having to boil and drain pasta.
