Preheat your oven to 190°C (375°F). Lightly grease your baking dish with oil or butter. This helps prevent sticking and makes cleaning easier after cooking.

Place uncooked pasta into the baking dish. Spread it evenly across the bottom. Make sure the pasta is not clumped together for even cooking.

Pour marinara sauce and water over the pasta. Stir gently to combine. Ensure all pasta is covered with liquid so it cooks properly in the oven.

Place frozen meatballs on top of the pasta mixture. Spread them evenly across the dish. This helps them cook evenly and absorb flavor.

Sprinkle Italian seasoning, garlic powder, salt, and black pepper over everything. This adds flavor and makes the dish more delicious.

Cover the dish tightly with aluminum foil. Bake for 30 minutes. This step helps cook the pasta and soften the meatballs properly.

Remove foil carefully. Sprinkle mozzarella and parmesan cheese evenly on top. This creates a cheesy and golden crust after baking.

Return the dish to the oven without foil. Bake for another 15 minutes. The cheese should melt and turn slightly golden.

Remove from oven and let it rest for 5–10 minutes. This helps the sauce thicken. Serve warm and enjoy your homemade meal.
