Lasagna (plural Lasagne) is a classic Italian pasta casserole dish which consists of alternate layers of pasta, cheese, a sauce, and often other ingredients. Typical of the cuisine of Italy, many regional variations exist. In some areas, especially in the southern regions of Italy, the sauce is likely to be a simple tomato sauce or a ragù, whereas in other areas, particularly in Northern Italy, a Béchamel sauce is used.
The word lasagna comes from the Greek lasana or lasanon meaning “trivet or stand for a pot”, “chamber pot”. The Romans borrowed the word as “lasanum”, in Latin meaning “cooking pot”. The Italians used the word to refer to the dish in which lasagna is made. Later the name of the food took on the name of the serving dish.
