The Ultimate Guide to Fettuccine Alfredo

fettuccine alfredo is a simple pasta dish consisting of wide, flat fettuccine noodles coated in a luscious, buttery, and cheesy sauce. The original Italian version, created by Alfredo di Lelio in Rome in the early 20th century, used just butter and Parmesan cheese, relying on the heat of the pasta to create a smooth, creamy texture.

However, in the U.S., the dish evolved into a much richer, creamier version with the addition of heavy cream and garlic, making it even more indulgent. Today, it remains a popular choice for pasta lovers craving a decadent meal.
