Stuffed shells are a type of pasta that are large and tubular, designed to be filled with various ingredients. Typically, they are filled with a mixture of ricotta cheese, mozzarella cheese, and Parmesan cheese, often combined with herbs and spices for added flavor. After being stuffed, the shells are usually baked in a sauce, often a tomato sauce or alfredo sauce, which enhances their taste and keeps them moist. This dish is popular in Italian-American cuisine and is often served as a main course. Stuffed shells can be customized with different fillings, such as ground meat, spinach, or vegetables, making them versatile and suitable for various dietary preferences. They are commonly enjoyed at family gatherings and special occasions.
