📝 How to make miyeok-guk
Soak the seaweed in plenty of cold water for 20–30 minutes until fully expanded. Rinse it two or three times, squeeze out the water and cut it into bite-sized pieces.
Cut the beef into bite-sized pieces.
Heat the sesame oil in a pot over medium heat and stir-fry the beef for about 2 minutes, until browned on the outside.
Add the seaweed and 1 tablespoon of soup soy sauce and stir-fry for 3 minutes.
Add the water, bring to a boil, then cover and simmer for 20–30 minutes — the longer it simmers, the richer it gets.
Add the garlic and season with the remaining soup soy sauce and salt to taste. Simmer 5 minutes more and serve with rice.
💡 Tips for the best miyeok-guk
- Dried seaweed expands about tenfold — 20 g is plenty for four people.
- Soup soy sauce seasons without darkening the broth; regular soy sauce will make it brown and sweeter.
- For seafood versions, skip the beef and sauté mussels, clams or shredded dried pollock in the sesame oil instead.
Why Koreans eat seaweed soup on birthdays
Seaweed is rich in iodine and minerals, and for generations Korean mothers have eaten miyeok-guk after childbirth to recover. Eating it on your birthday is a way of remembering your mother — and "Did you have seaweed soup?" is a common way of asking whether someone celebrated their birthday.
There is also a playful superstition that students should avoid it before exams: slippery seaweed might make you "slip" and fail.
