Kimchi-guksu is a traditional noodle soup originating from South Korea. The dish is usually made with a combination of kimchi, gochujang (hot pepper paste), wheat flour noodles (somyeon), nori, scallions, vegetable stock, sesame oil, sesame seeds, sugar, and salt.

The noodles are boiled in stock until they're chewy and soft. Once drained, they're divided into soup bowls and covered with the hot stock. A mixture of kimchi, gochujang, sesame oil, sesame seeds, and sugar is added to each serving, and the dish is garnished with nori sheets and scallions before it's served hot.
