Alfredo sauce
Rich, buttery, and cheesy, with a smooth, thick texture.
Lens analyzedAlfredo sauce is a rich, creamy pasta sauce built from butter, cream, and Parmesan, traditionally tossed with fettuccine until it clings to the noodles. Jarred versions thicken the base further so it holds up on a store shelf rather than needing refrigeration until opened.
Where it comes from
Alfredo sauce takes its name from Alfredo di Lelio, a Rome restaurateur who tossed fettuccine with butter and Parmesan for his wife after childbirth in the early 20th century. The cream-heavy version sold in jars today is largely an American adaptation of that much simpler original dish.
Buying it
Check the ingredient list for real cream and Parmesan versus a starch-thickened imitation, since the two taste noticeably different.
Storing it
Store unopened jars in the pantry; refrigerate after opening and use within about a week, since dairy-based sauces spoil once exposed to air.
Keeps about 1 year in the pantry.
