What ingredients are primarily used to make Alfredo sauce?

Alfredo sauce is traditionally made using a combination of butter, heavy cream, and parmesan cheese. This rich and creamy sauce originated in Italy and is known for its simple yet luxurious flavor profile. The butter is melted and blended with heavy cream to create a smooth base, while the parmesan cheese adds a savory depth and distinctive richness. This combination not only gives Alfredo sauce its characteristic creamy texture but also contributes to its mildly tangy flavor, making it a perfect complement to pasta dishes.

Other choices contain ingredients that are not part of a traditional Alfredo sauce. For instance, using tomatillo or ground beef introduces an entirely different flavor profile and is more aligned with Mexican or Tex-Mex cuisine. Pesto typically combines basil with nuts, cheese, and olive oil, while the last option focuses on cream and tomato flavors, which diverge from the classic creamy cheese sauce that defines Alfredo.
