Shredded Mozzarella Cheese Offers a creamy, gooey topping; swap for cheddar or a dairy-free version if desired.

How to Make Dump-and-Bake Meatball Casserole
Preheat your oven to 375 °F (190 °C). This ensures that your casserole bubbles to perfection and the cheese melts beautifully.
Combine the ingredients in a large baking dish: add frozen meatballs, uncooked pasta, marinara sauce, water, Italian seasoning, garlic powder, salt, and pepper. Stir well to mix everything together. The flavors will meld beautifully in the oven!
Cover the baking dish tightly with aluminum foil. This step is key for creating steam, which helps the pasta cook evenly and absorb the delicious sauce.
Bake in the preheated oven for 30 minutes. As it cooks, the kitchen will fill with an irresistible aroma that hints at the cozy meal to come.
Uncover the dish and stir gently. Check the pasta for doneness the pasta should be tender but not mushy. If it needs a little more time, cover and bake for a few more minutes.
Sprinkle shredded mozzarella cheese evenly over the top. This is where the magic happens; the cheese will melt and create that gooey, comforting layer we all crave.
Return the uncovered dish to the oven; bake for an additional 10-15 minutes until the cheese is bubbly and golden brown, bringing a delightful golden crust to your casserole.
Cool for 5 minutes after baking. This resting time allows the casserole to set a bit, making serving easier. Garnish with fresh basil for a touch of color and freshness, and then serve hot!
Optional: Drizzle with a bit of olive oil for an extra touch of richness.
