In a large oven-safe pan, combine the pasta, marinara sauce, water, and Italian seasoning.
Stir everything together and season with salt and pepper.
Bring it to a simmer over medium heat on the stovetop for about 5 minutes.
Remove from heat, sprinkle the mozzarella and Parmesan cheese on top.
Transfer the pan to the oven and bake for 20 minutes or until the cheese is bubbly and golden.
