Yukgaejang or spicy beef soup is a spicy, soup-like Korean dish made from shredded beef with scallions and other ingredients, which are simmered together for a long time. It is a variety of gom guk, or thick soup, which was formerly served in Korean royal court cuisine. It is thought to be healthful and is popular due to its hot and spicy nature.
In addition to shredded beef, scallions, and water, the dish generally also includes bean sprouts, gosari (bracken fern), torandae (taro stems), sliced onion, dangmyeon (sweet potato starch noodles), chili powder, garlic, deulkkae-garu (perilla seeds, also called wild sesame seeds), soy sauce, oil (sesame oil and/or vegetable oil), black pepper, and salt. Chili oil may also be used. Yukgaejang is generally served with a bowl of rice and kimchi.
