Step‑by‑Step Instructions for Dump-and-Bake Meatball Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven heats up, lightly grease a 9×13-inch baking dish with cooking spray or olive oil. This will prevent the pasta from sticking and ensure an easy cleanup later.
Step 2: Combine Ingredients
In the greased baking dish, combine the uncooked short pasta, marinara sauce, and 3 cups of water or broth. Sprinkle in the garlic powder, Italian seasoning, salt, and black pepper; mix everything together until the pasta is coated and evenly distributed, ensuring a homogenous base for your Dump-and-Bake Meatball Casserole.
Step 3: Add Meatballs
Take your frozen meatballs and press them gently into the pasta mixture, ensuring they are spaced evenly. This step is crucial for even cooking; you want the meatballs to be submerged in the sauce to absorb its delicious flavors.
Step 4: Cover and Bake
Cover the dish tightly with aluminum foil, sealing all edges to trap steam inside. Bake in the preheated oven for 35–40 minutes. Keep an eye on it; the casserole should be bubbling when it’s ready, indicating that the pasta is cooking nicely.
Step 5: Check for Doneness
Once the baking time is up, carefully remove the foil—be cautious of the hot steam that escapes. Check that the pasta is tender and the sauce is bubbling vigorously. If it looks too dry, you may add a little more water or broth before the next step.
Step 6: Add Cheese
Sprinkle the shredded mozzarella evenly over the top of the casserole, and if you choose, add the optional grated Parmesan. Return the dish to the oven, uncovered, and bake for an additional 10–15 minutes. You want the cheese to be melted, bubbly, and slightly golden—this is where deliciousness happens!
Step 7: Cool and Serve
After removing the casserole from the oven, let it cool for 10–15 minutes. This waiting period allows the flavors to meld and makes serving easier. Before serving, sprinkle fresh parsley on top for a touch of color and freshness. Your Homemade Dump-and-Bake Meatball Casserole is ready to bring smiles to the table!

Tips for the Best Dump-and-Bake Casserole
-
Foil Seal: Ensure a tight seal with aluminum foil during baking. This keeps moisture in, preventing dry pasta and enhancing the overall flavor of your dump-and-bake meatball casserole.
-
Hydration Check: If your marinara sauce is particularly thick, add an extra splash of water or broth before baking. This ensures the pasta has enough liquid to cook properly.
-
Resting Time: Let the casserole cool for 10–15 minutes after baking. This allows the flavors to meld beautifully and makes it easier to serve clean slices.
-
Pasta Choice: Stick to short pasta shapes like penne or ziti for the best texture. Avoid small shapes without adjustments, as they may not hold up well in the casserole.
