Creating your own Dump-and-Bake Meatball Casserole is incredibly easy if you follow these straightforward steps:

1. Preheat: Start by preheating your oven to 350°F (175°C).
2. Combine Ingredients: In a large baking dish, combine the uncooked pasta, marinara sauce, and water. Stir to mix evenly.
3. Add Meatballs: Disperse the frozen meatballs over the pasta mixture, ensuring they are well spaced for even cooking.
4. Season: Sprinkle with Italian seasoning, salt, and pepper to your taste for an extra flavor kick.
5. Cheese Layer: Add the shredded mozzarella and grated Parmesan on top of everything.
6. Cover and Bake: Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes.
7. Uncover and Finish: Remove the foil and bake for an additional 5-10 minutes until the cheese is bubbly and slightly golden.
8. Cool and Serve: Carefully take the casserole out of the oven and let it cool for a few minutes before garnishing with fresh basil.

Following these simple steps will ensure that you create an amazing meatball casserole the whole family will love!
