Step‑by‑Step Instructions for Dump-and-Bake Meatball Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that the heat is evenly distributed when you place the casserole inside, promoting even cooking and that gorgeous golden-brown finish. While the oven heats up, gather your ingredients and a large casserole dish to make the assembly process smooth and efficient.
Step 2: Combine Ingredients
In your large casserole dish, combine the frozen meatballs and your chosen pasta sauce. Pour in the uncooked pasta, allowing it to settle among the meatballs. The mixture will come together beautifully as the sauce envelops the ingredients, creating a base full of flavor. Feel free to mix gently, ensuring that everything is evenly coated.
Step 3: Add Water and Mix
Next, pour in the necessary amount of water over the mixture, ensuring that the pasta is adequately covered. This step is crucial for proper cooking and moisture retention in the Dump-and-Bake Meatball Casserole. Stir everything gently once more until the water, pasta sauce, and ingredients are well combined and harmoniously blended.
Step 4: Cover and Bake
Cover your casserole dish tightly with aluminum foil. This step traps steam, helping the pasta cook while absorbing the flavors of the meatballs and sauce. Place the dish in the preheated oven and bake for 40 minutes. When the timer goes off, your kitchen will be filled with delicious aromas, a sign that dinner is on its way!
Step 5: Add Cheese Topping
Once the initial baking time is complete, carefully remove the foil to reveal your bubbling casserole. Now it’s time to elevate it! Sprinkle a generous layer of cheddar and Parmesan cheeses over the top. The cheese will melt and brown beautifully, adding a delightful texture and flavor to your Dump-and-Bake Meatball Casserole.
Step 6: Bake Uncovered
Return the uncovered casserole to the oven and bake for an additional 10 minutes. Keep an eye on it; the goal is a deliciously golden and bubbly top that tempts the taste buds. When finished, the cheese should be melted and slightly crispy, creating an inviting finish to your comforting dish.
Step 7: Cool and Serve
After taking it out of the oven, let the casserole cool for a few minutes. This brief pause allows the flavors to settle and makes serving easier. Your Dump-and-Bake Meatball Casserole will be warm and inviting, ready to dish up for your hungry family or guests to enjoy!
