Making a cream-based Alfredo sauce is as simple as combining one part butter with one part heavy cream and two parts Parmesan cheese. Heat them together for a delicious sauce you can use on pasta, vegetables and everything in between.
To make the sauce, combine one cup butter and one cup heavy cream in a saucepan, and warm them over medium-low heat until almost simmering. Season to taste with salt and pepper, adjust heat to low, and mix in two cups Parmesan to stir until melted.
The most common use for Alfredo sauce is to mix it with fettuccine pasta, creating one of the ultimate comfort food dishes of all time. This classic dish has been around for over a century, ever since restaurant owner Alfredo di Lelio began making it in his establishment in Rome. When di Lelio's wife was pregnant and unable to keep any food down, Alfredo made her a simple dish of fresh pasta tossed with butter and Parmesan.
Alfredo's comforting recipe may not have made it out of Italy, if not for two famous American actors happening upon his restaurant in 1920. When Douglas Fairbanks and Mary Pickford tasted Alfredo's delicious sauce over the pasta of the day — fettuccine — they had to have the recipe. They brought it back to the U.S., and the rest is history.
