Lasagne, U.S. spelling sometimes lasagna, is a wide, flat pasta shape and possibly one of the oldest. The word also refers to a dish made with this type of pasta with different sauces and baked in the oven.
As with most other types of pasta, the word is a plural form, lasagne meaning more than one piece of lasagna ribbon.
Traditionally, the dough was prepared in Southern Italy with semolina and water and in the northern regions, where semolina was not available, with flour and eggs. Today in Italy, since the only type of wheat allowed for pasta is durum wheat, lasagne are made of semolina (from durum wheat) and eggs.
