The main ingredient in a traditional lasagna is pasta sheets. Lasagna is a classical Italian dish consisting of layers of pasta interleaved with fillings. The sheets of pasta are typically made from durum wheat semolina and water, and they provide the structure of the dish. Along with the pasta, traditional lasagna usually features a rich meat sauce, often made with ground beef or pork, béchamel (white sauce), and cheese, primarily mozzarella and ricotta. The dish is baked until bubbly and golden, creating a deliciously comforting meal that has become popular worldwide.
