Add the pasta, meatballs, Italian seasoning, spaghetti sauce and water to a 9x13 inch casserole dish, and mix gently to combine. Cover tightly with aluminum foil.
Cook in a 425℉ oven for 40 minutes.
Remove from oven and uncover. Sprinkle the shredded mozzarella evenly over the top and return the uncovered casserole to the oven for another 10 minutes, until the cheese has melted.
Allow it to sit at room temperature for about 5 - 7 minutes before serving.

Calories are automatically generated. For best results calculate based on your exact ingredients.
If freezing before cooking: we suggest cooking the noodles on the stovetop before adding them to the casserole dish (and skip adding water to the casserole). Cover with cheese from the start.
To cook from frozen: preheat the oven and bake the casserole covered with foil for 60 minutes. Remove foil and continue baking for another 10 - 15 minutes.
