This Dump and Bake Meatball Casserole is a game-changer for busy weeknights! So easy and delicious.

Preheat your oven to 375°F (190°C).
In a large baking dish, combine the frozen meatballs, uncooked pasta, marinara sauce, water, garlic powder, onion powder, and Italian seasoning. Stir to mix well.
Cover the baking dish tightly with aluminum foil.
Bake in the preheated oven for 35-40 minutes, or until the pasta is tender and the meatballs are heated through.
Remove the foil and sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top.
