Federal Way Korean Soup: Beef and Radish Guk Recipe

This home-style Korean beef-and-radish soup, called soegogi-muguk, combines tender beef, Korean radish, garlic, and a light savory broth. It is warming without being heavy, easy to serve with rice, and has plenty of family and regional variations; this recipe offers a straightforward version rather than a copy of any particular Federal Way restaurant’s soup.

Ingredients

1 lb (450 g) beef chuck or brisket, cut into ½-inch (1.25 cm) cubes
1 tbsp (15 ml) toasted sesame oil
8 cups (1.9 L) water
1 lb (450 g) Korean radish, peeled and cut into ½-inch (1.25 cm) pieces
½ medium yellow onion, about 2½ oz (75 g), peeled and left in one piece
5 garlic cloves, about ½ oz (15 g), finely minced
2 tbsp (30 ml) Korean soup soy sauce (guk-ganjang)
1 tsp (6 g) fine salt, plus more to taste
2 green onions, about 1 oz (30 g), thinly sliced
¼ tsp (0.5 g) ground black pepper
1 tsp (3 g) toasted sesame seeds, optional

Instructions

Prepare the ingredients. Cut the beef and radish into similarly sized pieces so they cook evenly. Mince the garlic and slice the green onions, keeping the green portions for garnish if you like. Set out the measured water, soup soy sauce, salt, and pepper. This prep takes about 20 minutes, including peeling the radish.
Brown the beef. Heat the sesame oil in a heavy soup pot over medium heat. Add the beef in one layer as much as the pot allows, working in batches if needed, and stir for about 5 minutes. The pieces should lose their raw appearance and take on a little color, but they do not need a deep sear. If the pot looks dry between batches, add a teaspoon of water rather than more oil.
Start the broth. Add the minced garlic and stir for 30 seconds, just until fragrant. Pour in the water and add the onion, soup soy sauce, and salt. Bring the liquid to a boil, then lower the heat to maintain a gentle simmer. Skim off any gray foam that gathers on the surface during the first few minutes for a cleaner-looking broth. Cover the pot with the lid slightly ajar and simmer for 45 minutes.
Cook the radish. Add the cut radish and stir gently. Bring the broth back to a quiet simmer, then cook for 20 minutes, until the radish is tender when pierced with a fork but still holds its shape. A hard boil can break up the radish and make the broth cloudy, so adjust the heat as needed.
Check the beef and season. Check the thickest beef cube 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. Once the cube reaches that temperature, lift a representative piece onto a clean plate for 3 minutes, then return it to the soup. The beef should also be tender; if it is still firm, simmer the soup longer and check again. Taste the broth and add salt a little at a time if needed.
Finish and serve. Stir in the black pepper and half of the sliced green onions. Simmer for 2 minutes, then turn off the heat. Ladle the soup into bowls and top with the remaining green onions and sesame seeds, if using. Serve hot, with rice on the side.

Tips

Choose the right radish. Korean radish, often labeled mu, is squat and firm, with a crisp texture and mild sweetness. Daikon is the easiest substitute and works well in this soup, though it is usually longer and can taste a little milder. Peel either one and cut it into even pieces so it softens at the same rate.
Know your soy sauce. Guk-ganjang, or Korean soup soy sauce, seasons broth without making it as dark as many regular soy sauces. If you cannot find it, use 1 tablespoon (15 ml) regular light soy sauce and begin with less salt; the substitute can make the broth darker and more assertively savory. Taste before adding the full amount of salt.
Keep the simmer gentle. A rolling boil can make beef tougher and break apart the radish. Look for small, occasional bubbles rather than vigorous churning. If the broth reduces more than you want, add hot water in small splashes and taste again before adding extra seasoning.
Cut evenly and season at the end. Uniform beef cubes make the thermometer check more useful and help the pieces finish together. Broths vary with the saltiness of the soy sauce and the beef, so use the listed salt as a starting point and make the final adjustment after the radish has cooked.

Serving Suggestions

Serve each bowl with a scoop of freshly cooked short-grain rice, either beside the soup or added directly to the broth. Keeping the rice separate lets diners choose how much to add and prevents leftover rice from soaking up all the soup. For a fuller Korean-style table, offer small side dishes such as kimchi, seasoned spinach, or crisp cucumber; a few contrasting bites are enough, and none needs to be complicated.

This soup is satisfying as a simple lunch or dinner, especially when you include the beef and radish in every serving. Put extra sliced green onion, black pepper, and sesame seeds on the table so everyone can finish their own bowl. If serving a group, keep the pot covered over very low heat only while people are being served, rather than boiling it for a long time; extended cooking can soften the radish too much and concentrate the salt.

Variations

Make a lighter broth. For a less rich result, trim visible fat from the beef before cutting it and spoon excess fat from the surface after simmering. You can also refrigerate the broth until the fat firms, lift it off, and reheat the soup later. This takes additional chilling time, so it is best treated as a make-ahead option rather than part of the stated recipe time.

Add a little heat. Stir a small amount of gochugaru, Korean red pepper flakes, into your bowl, or add ½ teaspoon (about 1 g) to the pot with the garlic. Gochugaru brings gentle warmth and a red tint; it changes the mild, clear character of the base soup, so serving it at the table is an easy way to keep the main pot mild.

Use a different cut. Beef brisket gives a deeper, slightly richer broth, while chuck is convenient and becomes tender with a long simmer. If using a larger piece of brisket instead of cubes, allow more time for it to soften, check it for tenderness, and cut it into bite-size pieces before serving. Do not rely on the recipe’s stated cooking time for an unusually large piece.

Make it vegetarian. Replace the beef with firm tofu and use a vegetable broth or water with dried kelp for a savory base. Add the tofu during the last 10 minutes so it warms without breaking apart. Use a vegan soup soy sauce if needed. This is a useful variation, but its flavor will be lighter and less beefy than the original.

Storage and Reheating

Refrigerate the soup within 2 hours of cooking, dividing a large pot among shallow containers so it cools more quickly. Store the broth and rice separately when possible. The soup keeps for 3 to 4 days in the refrigerator. If the beef fat firms on top, remove as much as you like before reheating. For longer storage, freeze the soup in airtight, meal-sized containers for about 2 to 3 months for best quality; leave a little headspace for expansion and thaw it overnight in the refrigerator.

Reheat only the portion you plan to eat in a saucepan over medium heat, stirring occasionally, until steaming throughout and at least 165°F (74°C). Check the temperature with a food thermometer, especially in a thick portion with several beef pieces. Add a splash of water if the broth has reduced or become salty after storage. A microwave also works: cover the bowl loosely, stir partway through heating, and confirm that the center reaches 165°F (74°C). Avoid repeatedly cooling and reheating the entire pot.

Frequently Asked Questions

What is Korean beef-and-radish soup called?
It is commonly called soegogi-muguk, meaning beef-and-radish soup. Muguk is a broad name for Korean soup made with radish, and ingredients and seasoning can differ across households and regions. This version uses beef, Korean radish, garlic, and soup soy sauce.

Can I make this soup without Korean soup soy sauce?
Yes. Use light soy sauce and reduce the added salt at first, then taste the finished broth. Korean soup soy sauce is generally lighter in color and has a particular savory flavor, so regular soy sauce can make the soup darker and stronger. Avoid adding the full salt amount until you have tasted the substitute.

Can I use daikon instead of Korean radish?
Yes. Peel the daikon and cut it to the same size as the Korean radish pieces in the recipe. It will become tender in a similar amount of time, although its flavor may be a little milder. Start checking it near the end of the 20-minute simmer so it does not become too soft.

Why is my broth cloudy?
A vigorous boil can agitate the beef and radish and cloud the broth. Some cloudiness is normal in a home-style soup and does not mean it has gone wrong. For a clearer appearance, skim foam as it forms, keep the pot at a gentle simmer, and stir carefully after adding the radish.

Can I prepare the soup ahead?
Yes. Cook it fully, cool it promptly in shallow containers, and refrigerate it within 2 hours. Reheat the portion you need to 165°F (74°C). The broth may taste more blended the next day, and the radish may soften a little more on reheating, so avoid boiling it hard.

What should I serve with the soup?
Steamed rice is the classic, practical partner because it balances the savory broth and makes the soup a more complete meal. Kimchi or a simple vegetable side adds a crisp, tangy contrast. Keep the sides optional: the soup already contains beef and radish, so rice alone is enough for a straightforward dinner.
