Cut the Korean beef, radish, green onion, and garlic into bite-sized pieces.
Add sesame oil to a pot and stir-fry the beef.
When the beef is cooked, add the radish and stir-fry together.
Pour 500 ml of water and bring to a boil.
When the broth boils, season with green onions, minced garlic, soy sauce for soup, salt, and pepper.
Continue boiling until the radish turns translucent, then finish.
