Lasagna (singular, pronounce [laˈzaɲa] in Italian; plural lasagne pronounced [laˈzaɲe]) is both a form of pasta in sheets (sometimes rippled, though seldom so in Italy) and also a dish, sometimes named lasagne al forno (meaning "oven-cooked lasagne") made with alternate layers of pasta, cheese, and often ragù (a meat sauce) or tomato sauce.
