Step‑by‑Step Instructions for Dump and Bake Meatball Casserole
Step 1: Preheat and Prep
Begin by preheating your oven to 425°F (220°C). While the oven warms up, lightly grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking. This step is crucial, as it ensures your Dump and Bake Meatball Casserole comes out smoothly without any fuss.
Step 2: Combine Ingredients
In your prepared baking dish, combine uncooked penne pasta, rich marinara sauce, and water or beef broth. Next, add the frozen meatballs directly into the mix, along with Italian seasoning, garlic powder, and onion powder if desired. Stir everything together until evenly coated, ensuring that the pasta is submerged in the sauce for optimal cooking.
Step 3: Cover and Bake
Once your ingredients are mixed well, cover the baking dish tightly with aluminum foil. This will help trap steam and moisture, allowing the pasta to cook properly. Bake in the preheated oven for 35-40 minutes, or until the pasta is tender and the meatballs are heated through. You’ll know it’s ready when the pasta appears plump and the meatballs are warmed.
Step 4: Add Cheese
After 35-40 minutes of baking, carefully remove the foil and sprinkle a generous layer of shredded mozzarella and grated Parmesan cheese over the top of the casserole. The cheese will melt beautifully and create a golden, bubbly layer that enhances the overall comfort of this Dump and Bake Meatball Casserole.
Step 5: Final Bake
Return the uncovered casserole to the oven and bake for an additional 10-15 minutes. You’ll want to watch for the cheese to melt completely and turn golden brown. The bubbling edges will signal that the Dump and Bake Meatball Casserole is nearly ready to serve, filling your kitchen with delightful aromas.
Step 6: Rest and Serve
Once baked to perfection, remove the casserole from the oven and let it rest for 5-10 minutes. This resting period allows the flavors to meld together, making each bite even more satisfying. If desired, garnish with freshly chopped parsley for a pop of color before serving your delicious Dump and Bake Meatball Casserole to the family.
