Bring water to a boil in a large pot. Once the water boils, add the noodles and cook according to the package directions (I like to cook al dente). Drain. Meanwhile, heat a skillet over medium heat. Melt 1 tablespoon of butter. Stir in 1 teaspoon of garlic. Season shrimp with salt and pepper before adding it to the skillet.Cook shrimp until completely pink and cooked through. Set aside in a bowl and cover. In the skillet, melt 7 tablespoons of butter over medium-low heat. Stir in 2 teaspoons of garlic and cook until fragrant. Pour in the heavy cream, and add salt, pepper, and Italian seasoning. Stir and bring to a low simmer.
Once it has simmered, turn the heat down to low. Add the parmesan and romano cheese. Stir and melt the cheese. Bring to a low simmer until thickened slightly.
Toss the noodles in the sauce then add the shrimp to the top of the pasta. Garnish with parsley if using. Serve.
Store leftovers in an airtight container in the refrigerator for 3-4 days.
