Jaengban guksu is a traditional cold noodle salad originating from South Korea. This versatile communal dish is usually made with a combination of soba noodles, chicken stock, soy sauce, lettuce, cucumbers, bell peppers, carrots, onions, sugar, sesame oil, and wine vinegar.

The stock is mixed with soy sauce, vinegar, sugar, and sesame oil, and the noodles are cooked, drained, rinsed, and left to cool. The noodle salad is then arranged on a circular platter – cucumbers, carrots, bell peppers, and onions are pushed to the edge of the circular platter, while the noodles are placed in the center.

Before serving, the dressing is poured over the salad and each person takes a desired portion from the platter. Jaengban guksu is often served as an accompaniment to Korean barbecue.
