Fettuccine Alfredo

Fettuccine Alfredo is a pasta dish made from fettuccine pasta tossed with Parmesan cheese and butter. As the cheese melts, it emulsifies the liquids to form a smooth and rich coating on the pasta. It was named by an Italian restaurateur, Alfredo Di Lelio, at his restaurant Alfredo on the Via della Scrofa in Rome in 1914. Di Lelio sold the restaurant in 1943, and opened another in 1950 at Piazza Augusto Imperatore, at first called "L'Originale Alfredo" and now "Il Vero Alfredo"; his nephews now manage it.

Though pasta with butter and cheese—"fettuccine in bianco" or "fettuccine burro e parmigiano"—is common, the name "fettuccine Alfredo" is rarely used in Italy.

In US cuisine it is sometimes mixed with other ingredients such as broccoli, parsley, cream, garlic, shrimp, or chicken, or all of the above.
