National Lasagna Day is observed on July 29, 2020. Lasagne is a wide, flat pasta shape and possibly one of the oldest. As with most other types of pasta, the word is a plural form, lasagne meaning more than one piece of lasagna ribbon. The word also refers to a dish made with this type of pasta in several layers interspersed with layers of various ingredients and sauces.
Lasagne originated in Italy, in the region of Emilia-Romagna. A traditional lasagne bolognesi is made by interleaving layers of pasta with layers of sauce, made with ragù, bechamel, and Parmigiano-Reggiano. In other regions and outside of Italy it is common to find lasagne made with ricotta or mozzarella cheese, tomato sauce, various meats, and miscellaneous vegetables. In all cases the lasagne are oven-baked. Lasagne is typically flavored with wine, garlic, onion, and oregano.
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 commercially sold pasta is durum wheat, commercial lasagne noodles are made of semolina. (With material from: Wikipedia)
