Step 1

Preheat oven to 400°F. Grease a 2 and 1/2 to 3 quart shallow casserole dish with oil or cooking spray.

Step 2

To the casserole dish add the pasta, sausage, diced tomatoes with juice, 1 cup of the mozzarella cheese, garlic powder, salt, and black pepper. Stir.

Step 3

Pour the milk over top and make sure that all of the pasta is submerged.

Step 4

Cover with two layers of aluminum foil and make sure it is very well sealed.

Step 5

Put it in the oven until the pasta is tender, 50-60 minutes.

Step 6

Remove from oven and sprinkle with the remaining 1 cup of mozzarella and the Parmesan.

Step 7

Return to oven uncovered just until cheese has melted, about 5 minutes.

Step 8

Remove from oven and let the pasta bake rest uncovered for 15 minutes before serving. This is important as the sauce really thickens up in this time.
