Lasagne sheets are wide and flat rectangular-shaped pasta sheets that are used to make lasagne, a popular Italian dish. The sheets are made from durum wheat semolina flour and water, and are usually precooked before being used in the dish. Lasagne sheets are typically layered with a variety of fillings, such as meat, cheese, and vegetables, and covered with a tomato or white sauce before being baked in the oven. The sheets can also be used to make vegetarian or vegan versions of the dish by using alternative fillings and sauces. Lasagne sheets can be found in most grocery stores, either dried or fresh, and are a staple ingredient for making this classic Italian dish.
