Fettuccine Alfredo - or really, Fettuccini al Burro - originated in Rome, Italy at a trattoria helmed by Chef Alfredo di Lelio, who made a very buttery version of a popular pasta served to children and people when they're sick. His buttery version captured the hearts of famous American actors who brought the concept back to the states. In an attempt to recreate the delicious creamy pasta, American chefs added heavy cream (which was not in di Lelio's version), thus creating what we now to day as Fettuccini Alfredo
