One pot is all you need! Melt butter in a large skillet over medium high heat. Add garlic and cook, stirring frequently until golden. Stir in chicken broth, milk and uncooked fettuccine – season with salt and pepper, to taste. Bring to a boil – reduce heat and simmer, stirring occasionally, until pasta is cooked through, about 18-20 minutes. Stir in Parmesan. If the mixture is too thick, add more milk as needed until desired consistency is reached. Serve immediately, garnished with parsley, if desired.
