How to Make Dump and Bake Meatball Casserole (Step-by-Step)

Step 1: Preheat the Oven

Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a little cooking spray or olive oil to prevent sticking.

Step 2: Combine the Ingredients

In your prepared baking dish, combine the frozen meatballs, uncooked pasta, marinara sauce, and garlic powder. Mix everything together so the pasta is well-coated in the sauce. Make sure the meatballs are evenly spread out.

Step 3: Add the Cheese

Top the mixture with the shredded mozzarella cheese and sprinkle with Parmesan cheese (if using). The cheese will melt into the sauce as it bakes, making the casserole gooey and delicious.

Step 4: Bake

Cover the dish with aluminum foil and bake for 35–40 minutes. After 20 minutes, take off the foil to let the cheese get golden and bubbly on top. You’ll know it’s ready when the pasta is cooked through and the cheese has fully melted.

Step 5: Serve

Once it’s done baking, remove from the oven and let it sit for 5 minutes before serving. Enjoy your delicious one-meal casserole!

Tips for Perfect One-Pot Meatball Casserole Every Time

• Use uncooked pasta: This will absorb the sauce as it cooks, giving it a better flavor and texture. Make sure to stir the pasta and sauce to combine well.
• Cover the casserole: This helps the pasta cook evenly and keeps the moisture in, especially if you’re using uncooked pasta.
• Try different sauces: Feel free to experiment with other sauces, such as Alfredo or a spicy arrabbiata, for a different flavor.
• Add extra veggies: You can sneak in some spinach, zucchini, or bell peppers for added nutrition. Just stir them in with the other ingredients before baking.
