What is the Italian plural form of the word 'lasagna'?

The Italian plural form of the word “lasagna” is lasagne. In Italian, lasagna traditionally refers to an individual pasta sheet, while lasagne refers to multiple sheets or the layered dish made from them.

Italian regional usage adds an important wrinkle. Northern Italians commonly call the baked dish lasagne, whereas southern Italian usage more often favors the singular lasagna for the dish. Both forms have influenced English: “lasagne” is especially common in British English, while “lasagna” is more usual in American English.

The word has ancient roots. Proposed sources include the Greek laganon, a flat sheet of dough, and the Latin lasanum, meaning a cooking pot or container. A lasagna-like dish was documented in medieval Italy, although early recipes differed substantially from the tomato-and-meat version familiar today.
