Noodles are a type of food made from unleavened dough which is either rolled flat and cut, stretched, or extruded, into long strips or strings. Noodles are a staple food in many cultures and made into a variety of shapes. The most common noodles are those derived from either Chinese cuisine or Italian cuisine. Chinese noodles are known by a variety of different names, while Italian noodles are known as pasta.

While long, thin strips may be the most common, many varieties of noodles are cut into waves, helices, tubes, strings, or shells, or folded over, or cut into other shapes. Noodles are usually cooked in boiling water, sometimes with cooking oil or salt added. They can also be steamed, pan-fried, deep-fried, or baked. Noodles are often served with an accompanying sauce or in a soup, the latter being known as noodle soup. Noodles can be refrigerated for short-term storage or dried and stored for future use.
