Bucatini is a type of pasta that is long and thin with a hollow center, similar to spaghetti but thicker and with a hole running through the center. It is typically made from durum wheat semolina and water, and has a slightly chewy texture. Bucatini is a popular pasta shape in Italian cuisine, especially in the regions of Lazio and Campania. It is often served with tomato-based sauces or with cheese and pepper, a classic Roman dish called "cacio e pepe." Bucatini's hollow center also makes it ideal for holding onto thick and hearty sauces, such as amatriciana sauce. It is a versatile pasta shape that can be used in a variety of dishes, including pasta salads and casseroles. With its unique texture and ability to hold onto flavorful sauces, bucatini is a delicious and satisfying addition to any pasta dish.
