Gomtang (Korean Clear Beef Bone Soup with Brisket)

Korean gomtang is a quietly robust beef soup, valued for its clear, savoury broth and tender slices of meat rather than heavy seasoning. In this version, marrow bones are blanched and rinsed before a long gentle simmer with brisket and garlic, giving the soup depth while keeping the flavour clean. The brisket is sliced across the grain and served over short-grain rice, with hot broth ladled over the top and spring onion added for freshness. Salt and black pepper are kept deliberately simple, so each bowl can be adjusted at the table — a practical, comforting way to serve a deeply flavoured beef soup without making it feel rich or heavy.

Why this recipe works

  • Clear, clean broth: Blanching and rinsing the bones before the main simmer helps remove impurities, giving the soup its characteristic clarity.
  • Deep beef flavour: Marrow bones build body in the broth while brisket adds savoury depth and provides tender slices for serving.
  • Seasoned at the table: Keeping the broth mild lets each bowl be adjusted with salt, pepper and spring onion to suit individual taste.

Timing notes

  • Mostly hands-off cooking: The active work is brief, but the broth needs a long, steady simmer to draw flavour from the bones and tenderise the brisket.
  • Serve piping hot: Gomtang is best ladled over rice while the broth is very hot, so slice the beef and spring onion before assembling the bowls.

Authenticity notes

  • Mild by design: Gomtang is typically served with minimal seasoning in the pot, allowing diners to add salt and pepper at the table.
  • Rice in the bowl: Short-grain rice is commonly served with the broth, making the soup more substantial without clouding its clean flavour.

Texture tips

  • For a cleaner finish: Chill the strained broth, lift off the solidified fat, then reheat gently for a lighter, clearer soup.
  • Slice the brisket correctly: Cut the brisket thinly across the grain so the meat stays tender in each spoonful.

Make-ahead tips

  • Keep rice separate: Store the broth, brisket and rice separately so the rice does not absorb the liquid and soften too much.
  • Freeze the broth: The strained broth freezes well without the rice; defrost overnight in the fridge before reheating.
  • Reheat gently: Warm the soup on the hob until piping hot, adding a little water if the broth has reduced during storage.

  1. Put the beef marrow bones in a stockpot and cover with cold water. Bring to the boil and boil for 10 minutes to draw out impurities, then drain through a colander and rinse the bones well under running water. Rinse out the pot.
  2. Return the cleaned bones to the pot and add the brisket and garlic. Cover with fresh cold water, bring to a gentle simmer, then skim any foam from the surface. Keep at a steady, low simmer for 2 hours, topping up with hot water if needed to keep everything submerged.
  3. Lift out the brisket and set aside to cool slightly. Continue simmering the bones for 45 minutes to deepen the broth. Meanwhile, rinse the short-grain rice until the water runs mostly clear, then cook it in a saucepan with water until tender.
  4. Strain the broth through a sieve into a clean pot, discarding the bones and garlic. Bring the broth back to a gentle simmer and season with the fine sea salt and black pepper, keeping it mild as gomtang is usually adjusted at the table. Slice the brisket thinly across the grain.
  5. Thinly slice the spring onion. Divide the rice between bowls, top with sliced brisket, then ladle over the hot broth. Finish with spring onion and add extra fine sea salt and black pepper to taste.

Tips

  • Keep the broth at a gentle simmer rather than a rolling boil to help it stay clear; skim the surface whenever foam appears.
  • For a cleaner flavour, chill the strained broth, lift off any solidified fat, then reheat gently until piping hot before serving.
  • If serving young children, season very lightly in the pot and let everyone adjust with fine sea salt and black pepper at the table.

Substitutions

  • Replace beef brisket with beef shank for a slightly more gelatinous, richer mouthfeel.
  • Replace spring onion with finely sliced white onion added to the bowls just before serving for a sharper bite.

Storage

  • Refrigerate up to 3 days
  • Cool the broth and brisket quickly, then refrigerate separately if possible. Reheat the soup gently on the hob until piping hot; add a splash of water if it has reduced. Freeze the strained broth (without rice) for up to 3 months; defrost overnight in the fridge before reheating.
