What Is Alfredo Sauce?

Classic Alfredo sauce originated in Italy as a simple combination of butter, Parmesan cheese, and pasta water. The American-style Alfredo we know and love has evolved into a richer sauce made with cream, butter, garlic, and Parmesan, creating the silky texture most people associate with Alfredo today.

This recipe follows the American creamy Alfredo style, which pairs perfectly with penne pasta.
