What is Udon?

Udon are thick, white noodles made from wheat flour, water, and salt. They have a chewy, soft texture and are usually round or slightly flat. Udon is most often served in a bowl of broth, which can be mild or strong depending on the region. Toppings are varied and can include sliced scallions, tempura shrimp, sweet fried tofu, fish cake, or a sprinkle of shichimi spice. In summer, udon is sometimes served cold with dipping sauce or as a salad with vegetables and chicken.

Where does Udon come from?

Udon comes from Japan, where it has been a staple for centuries. The noodle’s thickness and shape have changed over time and differ by region. In the Edo period, only the thickest wheat noodles were called udon, while thinner, chilled versions had other names. Regional specialties have developed, such as Sanuki udon from Kagawa and yaki udon from Kitakyushu. Japanese influence spread udon to places like Palau, Micronesia, Korea, and the Philippines, where local versions have emerged.

How is Udon made?

To make udon, wheat flour, water, and salt are mixed into a dough, which is kneaded, rolled out, and cut into thick strips. The noodles are boiled until soft and chewy. For soup, they are placed in a bowl and covered with hot broth made from dashi (a stock from fish and kelp), soy sauce, and mirin (a sweet rice wine). Toppings are added according to the style or season. Cold udon is chilled after cooking and served with dipping sauce or salad ingredients.
