Korean Rice Soup (Gukbap) with Beef and Radish

Korean rice soup, or gukbap, is a comforting bowl of hot broth served with rice, often topped with meat and scallions. This home-style beef version simmers brisket with Korean radish for a clean, savory broth, while keeping the rice separate so each bowl stays pleasantly distinct.

Ingredients

1½ cups (300 g) uncooked short-grain rice
1¾ cups (420 ml) water for cooking the rice
1½ lb (680 g) beef brisket, preferably in one piece
10 cups (2.4 L) cold water for the broth
12 oz (340 g) Korean radish, peeled and cut into ½-inch (1.25 cm) pieces; daikon is a good substitute
1 medium yellow onion (about 7 oz/200 g), peeled and halved
6 garlic cloves (about 18 g), peeled and lightly crushed
2 scallions (about 30 g), trimmed and cut into large pieces for the broth
1 tablespoon (15 ml) Korean soup soy sauce (guk-ganjang)
1½ teaspoons (9 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) ground black pepper
3 scallions (about 45 g), thinly sliced for serving
1 teaspoon (5 ml) toasted sesame oil, for serving
½ teaspoon (about 1 g) gochugaru (Korean red pepper flakes), optional, for serving
4 cups (about 800 g) kimchi, optional, for serving on the side

Instructions

Rinse and cook the rice. Rinse the rice in a bowl of cool water, gently rubbing the grains, then drain. Repeat three or four times, until the water is less cloudy. Cook the rice with 1¾ cups (420 ml) water in a rice cooker, or bring it to a boil in a covered saucepan, reduce the heat to low, and cook for about 15 minutes. Turn off the heat and leave it covered for 5 minutes. Keep warm while you make the broth; the rice can cook during the brisket’s long simmer.
Start the broth. Put the brisket in a large heavy pot and add 10 cups (2.4 L) cold water. Bring it just to a boil over medium-high heat, skimming off the gray foam that gathers at the surface. Add the onion, garlic, and the two large pieces of scallion. Lower the heat so the liquid maintains a gentle simmer rather than a rolling boil. Cover partially and simmer for 1 hour 35 minutes, turning the brisket once after about 45 minutes. A gentle simmer helps keep the broth clearer and prevents the meat from toughening from aggressive boiling.
Check the beef and rest it. Check the thickest part of the brisket with a food thermometer. USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of beef; the brisket will usually cook well beyond that temperature as it becomes tender. If it has not reached 145°F (63°C), continue simmering and check again. Lift the brisket onto a plate, let it rest for at least 3 minutes, and cover it loosely. If it is still firm when pierced, return it to the pot and simmer until tender before slicing.
Cook the radish in the broth. Remove and discard the cooked onion, garlic, and broth scallions. Skim excess fat from the surface with a spoon, leaving a little for flavor. Add the radish pieces and simmer the broth for 12 minutes, or until the radish is tender when pierced but still holds its shape. While it simmers, slice the rested brisket thinly across the grain. If the broth has reduced more than you like, add a little hot water.
Season and finish. Stir in the soup soy sauce, salt, and black pepper. Taste before adding more salt: soup soy sauce is salty, and the amount needed depends on your broth and the brand. Return the sliced beef to the pot and simmer for about 3 minutes, just until heated through. If you prefer a stronger garlic flavor, add a small amount of freshly grated garlic now rather than putting it all in at the beginning.
Serve the bowls. Divide warm rice among four bowls. Ladle the hot broth, radish, and beef over or around the rice, according to preference. Finish with sliced scallions and a few drops of sesame oil. Offer gochugaru and kimchi at the table so each person can adjust the heat and tang.

Tips

Keep the broth at a quiet simmer. A few small bubbles are enough. A hard boil can break up fat and proteins into the liquid, making it cloudy and greasy. Skimming early helps, but there is no need to remove every trace of fat; a light sheen gives the soup body.

Choose a practical radish substitute. Korean radish, sometimes labeled mu, is short and stout with a crisp texture and mild sweetness. Daikon works well if that is what you can find. It may soften a little faster, so begin checking it after 8 or 9 minutes. Turnip can work in a pinch, but its flavor is sharper and the finished soup will taste different.

Season gradually. Korean soup soy sauce is lighter in color and more concentrated than many everyday soy sauces. If you cannot find it, use regular soy sauce, starting with 2 teaspoons (10 ml), then add more to taste; it will darken the broth and can make it taste sweeter or more strongly soy-forward. The soup should be savory but not so salty that the rice disappears beneath it.

Do not leave the rice sitting in the pot of soup. Rice absorbs broth as it stands, so combining everything too early can turn a clear, brothy bowl into a thick one. For leftovers, store rice separately when possible and add it to each bowl when serving.

Serving Suggestions

Serve gukbap piping hot as a complete meal, with the rice either under the broth or in a separate bowl for diners to add a spoonful at a time. Both ways are useful: rice in the soup makes a filling, cohesive bowl, while separate rice lets you control how much broth each bite soaks up. Set out the sliced scallions, black pepper, sesame oil, and gochugaru so everyone can finish their own portion.

Kimchi is a classic, lively companion because its acidity and spice contrast with the mellow broth. A small dish of kkakdugi, the cubed radish kimchi often served with Korean soups, is especially fitting, though any crisp, tangy kimchi works. You can also offer a simple plate of seasoned greens or cucumber salad. Keep side dishes modest: the soup already has beef, radish, and rice, and the salty, sour accompaniments are meant to refresh the palate rather than compete with it.

Variations

Make a quicker thin-beef version. Replace the brisket with 1 lb (450 g) thinly sliced beef, such as brisket slices or another well-marbled cut. Make the broth with 8 cups (1.9 L) water and the onion, garlic, and scallions; simmer it for about 30 minutes, then add the radish and cook until tender. Add the sliced beef near the end and cook it thoroughly, checking that it reaches 145°F (63°C) as a whole-cut beef safe minimum, followed by a 3-minute rest. Thin slices cook quickly, so avoid a long boil that can make them chewy. This version has less of the deep, gelatinous body that comes from a long brisket simmer.

Use a different broth base. For a lighter, seafood-style variation, replace the beef and water with 8 cups (1.9 L) unsalted anchovy-kelp broth and omit the beef-cooking aromatics. Add the radish and simmer until tender, then season with soup soy sauce, salt, and pepper. Dried anchovies and kelp are traditional pantry ingredients for this kind of broth; if they are unavailable, use a mild, low-sodium vegetable stock, understanding that the flavor will be less distinctly Korean and less savory. Do not simmer kelp for a long time, as it can make the broth bitter.

Add a gentle chili finish. Stir gochugaru into a little sesame oil with sliced scallion and offer it at the table, rather than making the whole pot spicy. For a richer, more pungent finish, some cooks add a small spoonful of salted shrimp or extra garlic; these are optional seasonings, not requirements. Add any salty condiment gradually and taste before adding more salt.

Make it with leftover cooked rice. Use 4 cups (about 800 g) cooked rice in place of the uncooked rice and its cooking water. Prepare the broth as directed, then warm the rice directly in individual bowls with the hot soup. Leftover rice is convenient, but rice cooked in advance can be firmer or drier, so serve the broth generously and avoid simmering the rice in the pot for a long time.

Storage and Reheating

Cool the broth, beef, and rice promptly and refrigerate them within 2 hours of cooking. Store the broth with the beef and radish in a covered container and keep the rice in a separate container. Refrigerated, cooked soup and rice are best used within 3 to 4 days. If you know you will have leftovers, keep rice out of the soup from the start so it does not absorb most of the broth overnight.

For longer storage, freeze the broth with the beef and radish for up to 2 to 3 months; the radish may be softer after thawing. Freeze rice separately in meal-size portions if desired. Thaw in the refrigerator overnight, or reheat from frozen in a saucepan with a splash of water. Reheat soup on the stovetop until steaming throughout, stirring occasionally; leftovers should reach 165°F (74°C). Reheat rice until steaming hot as well, adding a spoonful of water and covering it to help keep the grains moist. Assemble bowls only when ready to eat.

Frequently Asked Questions

Is gukbap the same as rice porridge?
Not usually. Gukbap means soup with rice: it is typically a savory broth served with cooked rice, either in the same bowl or alongside it. Rice porridge, often called juk, cooks the rice in liquid until the grains soften and break down. This recipe keeps the rice grains intact and adds the broth at serving time.

Can I make the broth ahead?
Yes. Make the broth and cook the radish a day or two ahead, then refrigerate them promptly with the beef. Reheat the broth gently, slice or warm the beef in it, and cook the rice separately just before serving if you want the best texture. The broth may set slightly when cold because of the brisket; it will loosen as it heats.

Why is my broth cloudy?
The most common cause is a vigorous boil, which disperses fat and small particles through the liquid. Start with cold water, skim the foam as it comes to a boil, and keep the pot at a gentle simmer. A cloudy broth is still usable and flavorful; strain it through a fine sieve if you want a cleaner appearance, then return the radish and beef to the pot.

Can I use another cut of beef?
Yes. Beef shank or another collagen-rich stewing cut can make a satisfying broth, but its cooking time may differ. Check for tenderness as well as temperature, and simmer longer if the meat remains tough. A leaner cut may cook sooner but produce a lighter broth. If using ground beef, cook it to 160°F (71°C), the USDA FSIS safe minimum for ground meat; the texture and broth will be quite different from brisket gukbap.

Should the rice go into the soup before serving?
That is up to you. Adding rice to each bowl is convenient and traditional in many gukbap settings, while serving it separately lets each person choose the ratio. Avoid storing rice in the broth because it swells and absorbs liquid. If you enjoy a thicker, more unified bowl, add rice only to the portion you plan to eat and let it sit briefly before serving.
