Step‑by‑Step Instructions for Dump and Bake Meatball Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). While the oven warms, grab a 9×13-inch baking dish and generously grease it with cooking spray or olive oil to prevent sticking. This ensures the final casserole will slide out easily and remain intact for serving.
Step 2: Combine Ingredients
In the greased baking dish, combine the uncooked penne pasta, marinara sauce, and your choice of water or beef broth. Toss in the frozen meatballs along with the Italian seasoning, garlic powder, and onion powder, if using. Stir everything well, ensuring the pasta is fully submerged beneath the liquid and sauce to cook evenly during baking.
Step 3: Bake Covered
Cover the baking dish tightly with aluminum foil, creating a seal to keep the moisture in. Place it in the preheated oven and bake for 35–40 minutes. Check for doneness by peeking under the foil; the pasta should be tender and absorb most of the liquid, ready to be dressed with cheese.
Step 4: Add Cheese
Once the pasta is cooked, carefully remove the foil from the dish. Sprinkle shredded mozzarella cheese evenly over the top, followed by a generous layer of grated Parmesan cheese for that extra richness. This layer will create a delectable, gooey topping that contrasts beautifully with the hearty casserole below.
Step 5: Bake Uncovered
Return the completely uncovered casserole to the oven for an additional 10–15 minutes. Bake until the cheese is melted, bubbly, and golden in color, creating a tempting crust. Keep an eye on it to prevent over-browning, ensuring that lovely cheesiness remains perfectly intact.
Step 6: Rest and Serve
After baking, let your Dump and Bake Meatball Casserole rest for 5–10 minutes before serving. This step allows the flavors to meld further while the casserole sets slightly, making it easier to dish out. Optionally, finish with a sprinkle of fresh parsley for a touch of color and freshness before enjoying!
