Classic lasagna, which is more common in America and southern Italy, typically uses dried pasta noodles layered with marinara sauce, ricotta and mozzarella cheese, and does not always contain meat. This version of lasagna is said to have originated in Naples. Lasagna Bolognese, which originated in Bologna, is always made with a meat sauce called ragu Bolognese, fresh egg pasta and a rich and creamy béchamel sauce instead of ricotta.
