Step-by-Step Instructions
Follow these simple steps to create your Dump and Bake Meatball Casserole:
- Preheat your oven to 425°F (220°C) and grease a 9×13-inch baking dish. Greasing the dish helps prevent sticking and makes clean-up easier later.
- In the greased baking dish, stir together the uncooked penne pasta, marinara sauce, water (or beef broth), frozen meatballs, Italian seasoning, and optional garlic and onion powders until well mixed. Ensure that the pasta is fully submerged in the liquid to cook evenly.
- Cover the baking dish tightly with aluminum foil and bake for 35–40 minutes, or until the pasta is tender. This step is crucial as it allows the steam to cook the pasta properly.
- Once the pasta is cooked, remove the foil and sprinkle the mozzarella and Parmesan cheese on top. The cheese will create a golden, gooey layer that adds to the dish’s appeal.
- Return the casserole to the oven and bake uncovered for 10–15 minutes, until the cheese is melted, bubbly, and golden brown. Keep an eye on it to prevent burning.
- Let the casserole rest for 5–10 minutes before serving. This helps the dish set, making it easier to serve up. Garnish with fresh parsley if desired for a pop of color!

Storing and Reheating Tips
If you have leftovers, don’t worry! This casserole stores beautifully. Allow it to cool completely before transferring it to an airtight container. You can keep it in the refrigerator for up to 3-4 days. For longer storage, consider freezing it. Wrap the casserole tightly with plastic wrap and then aluminum foil to protect it from freezer burn. It can be frozen for up to 3 months.
When you’re ready to enjoy your leftovers, preheat your oven to 350°F (175°C) and cover the casserole with foil. Bake for 20-30 minutes, or until heated through. If you prefer to microwave, place a single serving on a microwave-safe plate and heat it for about 2-3 minutes, stirring halfway. Just be wary of hot spots!
