Gyeran-guk (Korean Egg Drop Soup)
Created by
The two-minute soup Korean children know by heart: beaten egg poured into a clear anchovy broth, left alone just long enough to set in soft ribbons.

Gyeran-guk lives or dies in the ten seconds after the egg hits the broth. People think the soup is easy because the ingredient list is short. It is easy, but it still asks for manners: a clear broth, lightly beaten egg, one gentle stir, and then your hands stay quiet.
My mother made this when rice was ready and the table still needed something warm. No one announced it. A pot of anchovy broth, three eggs, one scallion, and suddenly the meal had a soup. That is the place of gyeran-guk on the Korean table: quick, inexpensive, soft enough for a child, useful enough for a tired adult, and never too small to record properly.
The mistake is stirring like you are fixing something. You are not. Pour the egg thinly, wait five seconds, and move through it once. 손맛 is real; I measure it anyway. Three eggs to four cups of broth gives enough body without turning soup into scrambled egg, and that number is how you make the same calm bowl twice.
Gyeran-guk belongs to the everyday Korean guk family, the clear soups served with rice rather than as a special course. Eggs became a common home protein in the twentieth century as poultry farming expanded, and this soup settled naturally into budget meals, school mornings, and quick suppers because it turns a basic anchovy broth into a complete bowl in minutes.
The technique, the tradition, and the story behind every dish.

Instructions
- 1
Make the broth
Put the water, kelp, and cleaned anchovies in a small pot over medium heat. When the water reaches a steady simmer, remove the kelp, because kelp left too long makes the broth slick and bitter. Simmer the anchovies 8 minutes more, then lift them out. You should have a clear, savory broth, not a heavy one.
For the fastest weeknight bowl, use 4 cups broth you already made and refrigerated. The safe shortcut is prepared broth; the unsafe shortcut is skipping seasoning control. - 2
Season first
Stir in the soup soy sauce, salt, and minced garlic. Taste the broth before the egg goes in. It should be lightly seasoned but not salty, because egg softens the saltiness once it sets. If your soup soy sauce is very strong, hold back the salt until the end.
- 3
Beat the eggs
Beat the eggs in a bowl with chopsticks or a fork until the whites and yolks are just joined. Do not beat them foamy. Foam breaks into ragged bits in the soup, while lightly beaten egg sets in soft ribbons.
- 4
Pour and wait
Lower the heat so the broth is moving gently, not boiling hard. Pour the egg in a thin circle over the surface of the broth. Count 5 seconds before you touch it. This little wait lets the egg set into clouds instead of disappearing into grainy threads.
- 5
Stir once
Drag chopsticks or a spoon through the pot once or twice, gently. Stop there. Gyeran-guk lives or dies by restraint: too much stirring makes the soup cloudy and the egg small. Taste, then add a pinch more salt only if the broth has gone flat.
- 6
Finish the bowl
Scatter in the scallion and turn off the heat. Add the sesame oil and black pepper if you like them, but keep both light. Ladle into bowls at once, with rice and kimchi beside it. This soup is meant to arrive quickly and leave nothing heavy behind.
Chef Tips
- •Use soup soy sauce, guk-ganjang, if you have it. It seasons with a clean saltiness and deeper aroma than regular soy sauce. If you must use regular soy sauce, use 2 teaspoons instead of 1 tablespoon and make up the salt with a measured pinch.
- •Do not boil hard after the egg goes in. A rolling boil tears the egg into small rough pieces and clouds the broth. Gentle movement is enough.
- •Scallion is the usual finish. Gim, roasted seaweed, can be crumbled over the bowl at the table, but keep it optional. The soup should still taste like egg and broth first.
- •For children, leave out the black pepper and sesame oil. For a fuller adult bowl, add 80g soft tofu in small cubes before the egg, but do not let the tofu crowd the pot.
Advance Preparation
- •Anchovy-kelp broth can be made up to 3 days ahead and kept refrigerated. With broth ready, this soup takes about 5 minutes from stove to table.
- •Do not add the egg ahead of time. Gyeran-guk is best eaten as soon as the egg sets, before the ribbons toughen and the broth turns cloudy.
