Lasagne is a type of flat pasta that is commonly baked in layers with sauces and other ingredients. There are different theories about the origins of lasagne, including that it comes from an ancient Greek dish called "laganon" which was a flat sheet of pasta dough cut into strips. A traditional lasagne recipe involves layering a meat sauce, lasagne noodles, and a béchamel sauce mixture in a baking dish and baking for about 45 minutes. There are many varieties of lasagna such as chicken lasagna, ricotta lasagna, vegetarian lasagna, and Mexican lasagna.
