Spray a 9x13" casserole dish with non stick spray. Add the pasta to the bottom of the dish, in alternating directions.
12 oz linguini pasta
To a small mixing bowl add the broth, wine, onion, garlic, and half the parmesan cheese. Whisk together until smooth. Pour the mixture evenly out over the pasta, and stir gently to combine.
3 cups chicken broth, 1 cup white wine, 1 small white onion, 2 tbsp minced garlic, 1/2 cup shredded Parmesan cheese
Cover the casserole dish tightly with aluminum foil. Bake at 425° for 40 minutes, stirring halfway through.
After baking for 40 minutes, uncover the dish and stir the pasta- making sure it's cooked to al dente.
Stir the raw shrimp into the hot pasta. Spread the shredded mozzarella and remaining parmesan evenly out over top of the casserole dish.
1 lb frozen medium shrimp, 1 cup shredded mozzarella cheese
Bake uncovered for another 5-10 minutes.
Carefully remove the hot casserole dish from the oven. Stir in the butter, and season with salt & pepper- to taste.
2 tbsp butter
Serve with chopped fresh parsley leaves as a garnish and extra butter, if desired.
