Lasagna is a layered pasta dish from Emilia-Romagna, Italy, built with sheets of pasta, rich meat ragù, creamy béchamel, and melted cheese. The interplay of tender noodles, slow-cooked sauce, and silky béchamel creates a deeply satisfying texture and flavor that rewards the time invested. It's a showstopper for feeding a crowd and actually improves when made a day ahead, making it ideal for advance preparation.
