Step‑by‑Step Instructions for Dump and Bake Meatball Casserole
Step 1: Preheat & Prep
Begin by preheating your oven to 425°F (220°C). While the oven warms up, grab a 9×13-inch baking dish and lightly grease it with cooking spray or olive oil. This preparation ensures that your Dump and Bake Meatball Casserole won’t stick, allowing for easy serving and cleanup later.
Step 2: Combine Ingredients
In your prepared baking dish, combine uncooked penne pasta with marinara sauce and your choice of water or broth. Add in the frozen meatballs, Italian seasoning, garlic powder, and onion powder, stirring everything together until it’s evenly mixed. The sauce will help hydrate the pasta as it cooks, so make sure all the pasta is well-coated for the best flavor.
Step 3: Cover & Bake
Cover the baking dish tightly with aluminum foil, ensuring it’s sealed to keep moisture in. Place the dish in the preheated oven and bake for 35–40 minutes. As it cooks, the pasta will absorb the sauce and become tender, and the meatballs will warm through, filling your kitchen with delicious aromas.
Step 4: Add Cheese
Once the initial baking time is complete, carefully remove the foil from the baking dish. Sprinkle a generous layer of shredded mozzarella and grated Parmesan cheese across the top of the casserole. This will create a bubbly, golden cheese layer that enhances the overall flavor of your Dump and Bake Meatball Casserole.
Step 5: Bake Uncovered
Return the casserole to the oven without the foil and bake for an additional 10–15 minutes. Keep an eye on it; your dish is ready when the cheese is fully melted and starts to bubble slightly at the edges, creating an appetizing golden top that will have everyone eagerly waiting for dinner.
Step 6: Rest & Serve
Once baked to perfection, take your casserole out of the oven and allow it to rest for 5–10 minutes. This step helps the flavors meld together, making it easier to serve. If desired, garnish with fresh parsley before serving to add a touch of color to your comforting Dump and Bake Meatball Casserole.
