Bring a large pot of water to boil and cook 12 ounces linguini noodles according to package directions. Reserve 2 cups of pasta water. Drain the remaining water from the pasta and set aside.
In a large saucepan over medium-high heat, melt 1 tablespoon unsalted butter. Add ½ pound scallops and cook for 2-3 minutes. Add ½ pound large peeled and deveined shrimp, season with salt and pepper, and cook until no longer pink. Remove the scallops and shrimp and set aside on a plate.
Add the 2 cups reserved pasta water to the saucepan and bring to a boil. Add ½ pound mussels reduce to a simmer, and cover. Let the mussels steam for 5 minutes. Discard the ones that didn't open and set aside with the shrimp and scallops. Discard the leftover pasta water from the pan.
Creamy Lemon Garlic Sauce
Returning to the same pan over medium heat, add ¼ cup unsalted butter and melt. Add 3 cloves garlic, 2 cups heavy cream, 1 cup chicken broth, and 4 ounces cream cheese. Stir the sauce mixture until the cream cheese has melted and is smooth and creamy.
Add ¼ cup freshly shredded Parmesan cheese and the juice of a lemon. Simmer over medium-low heat until the sauce thickens.
Stir in the cooked seafood and pasta and heat through. Garnish with fresh chopped parsley and additional Parmesan cheese, if desired.
