What pasta shape is long, flat, and typically served with Alfredo sauce? Fettuccine is the correct answer.

Fettuccine is a thick, flat ribbon pasta associated especially with Roman cuisine. Its name means “little ribbons” in Italian, and it is traditionally made from flour and eggs. At roughly 6 millimeters wide, it is wider and thicker than spaghetti and generally broader than linguine.

The best-known pairing is fettuccine Alfredo, a Roman dish created and popularized by restaurateur Alfredo Di Lelio in the early 20th century. The original preparation used fettuccine, butter, and Parmesan cheese, which combine with pasta water into a smooth coating. Outside Italy, cream, chicken, shrimp, or vegetables are often added.

A common mix-up is tagliatelle, another flat ribbon pasta that is especially associated with Bologna and Emilia-Romagna. The shapes are similar, but fettuccine is the conventional answer for Alfredo sauce.
