What Korean noodle dish is served at banquets?

The Korean noodle dish traditionally served at banquets is janchi guksu. Its name literally means “banquet noodles,” linking the dish to celebrations and festive gatherings.

Janchi guksu uses thin wheat-flour somyeon noodles in a light broth. Anchovies and sometimes dasima, or kelp, provide the classic savory base, although beef broth may be used instead. The bowl is typically finished with strips of fried egg, zucchini, gim, scallions, and other garnishes, plus a sauce containing soy sauce, sesame oil, and chili powder.

The dish appears at weddings, birthdays, and hwangap celebrations marking a person’s sixtieth birthday. Long noodles symbolize longevity and a long-lasting marriage, which helps explain their ceremonial role. In Korean, janchi means feast or banquet, while guksu means noodles.

Janchi guksu is often confused with japchae, but japchae uses glass noodles stir-fried with vegetables and other ingredients. It is also different from kalguksu, whose noodles are cut from dough rather than thinly extruded somyeon.
