Janchi guksu is a Korean noodle soup often served at weddings and other celebrations, with long somyeon noodles in a light broth and colorful vegetable toppings. The noodles are associated with a long life and a lasting marriage, and this home-style version pairs a clear anchovy-and-kelp broth with zucchini, carrot, shiitake mushrooms, and a savory soy dipping sauce.
Ingredients
- 8 cups (1.9 L) water
- 1/2 cup (20 g) dried Korean anchovies, preferably large soup-stock anchovies with heads and guts removed
- 1 piece dried kelp, about 4 by 4 inches (10 by 10 cm or 8 g)
- 1/2 medium yellow onion (about 75 g), peeled and cut into wedges
- 2 garlic cloves (about 6 g), peeled and lightly crushed
- 1 tablespoon (15 ml) Korean soup soy sauce, called guk-ganjang
- 1/2 teaspoon fine salt (about 3 g), or to taste
- 12 ounces (340 g) somyeon, thin Korean wheat noodles, usually sold in bundles
- 1 medium zucchini (about 200 g), cut into thin matchsticks
- 1 medium carrot (about 60 g), peeled and cut into thin matchsticks
- 4 fresh shiitake mushrooms (about 80 g), stems removed and caps thinly sliced
- 2 teaspoons (10 ml) neutral cooking oil, divided
- 1/4 teaspoon fine salt (about 1.5 g), for the vegetables
- 3 tablespoons (45 ml) regular soy sauce
- 2 tablespoons (30 ml) water
- 1 tablespoon (15 ml) toasted sesame oil
- 2 scallions (about 20 g), thinly sliced
- 1 teaspoon (3 g) toasted sesame seeds
- 2 sheets roasted gim, Korean seaweed (about 5 g), crumbled for serving
Instructions
- Prepare the vegetables before cooking. Cut the zucchini and carrot into fine, even matchsticks so they cook quickly and are easy to pick up with noodles. Slice the shiitake caps thinly. If your anchovies are whole, remove the heads and dark innards if they are still present; this helps keep the stock from tasting bitter. Set the kelp, onion, garlic, and stock ingredients beside the stove.
- Make the broth. Put the water, anchovies, kelp, onion, and garlic in a large saucepan. Bring the pot to a boil over medium-high heat; the hot broth should exceed the USDA FSIS safe minimum of 145°F (63°C) for fish. Once boiling, lower the heat to maintain a gentle simmer. After 10 minutes, lift out and discard the kelp so it does not make the broth overly slick or strong. Continue simmering the anchovies, onion, and garlic for 10 more minutes.
- While the stock simmers, mix the dipping sauce. Stir together the regular soy sauce, water, sesame oil, scallions, and sesame seeds in a small bowl. This condiment is intentionally punchy: diners can add a little to their soup rather than making the whole pot salty. Set it aside at room temperature while you finish the rest of the meal.
- Strain the broth through a fine-mesh strainer into a clean pot, discarding the anchovies and vegetables. Stir in the soup soy sauce and 1/2 teaspoon salt. Taste a spoonful before adding more salt; brands of soup soy sauce vary in saltiness, and the dipping sauce will add seasoning at the table. Keep the broth hot over low heat, but do not let it boil hard while you prepare the noodles.
- Cook the toppings separately for distinct color and flavor. Heat 1 teaspoon of the neutral oil in a skillet over medium heat. Add the zucchini with a pinch of the measured vegetable salt and stir-fry for 2 to 3 minutes, just until softened but still bright. Transfer it to a plate. Add the remaining oil, then cook the carrot for about 2 minutes and the shiitake for 3 to 4 minutes, stirring each until tender. Keep the vegetables in separate little piles rather than mixing them together.
- Bring a large pot of unsalted water to a rolling boil. Add the somyeon and cook according to the package directions, commonly 3 to 4 minutes, stirring gently at first to separate the strands. Thin noodles turn mushy if left in hot water, so begin checking them at the early end of the package time. Drain as soon as they are tender, then rinse thoroughly under cold running water while gently swishing them with your fingers. This removes surface starch and stops the cooking.
- Divide the rinsed noodles among four deep bowls, arranging them in loose nests. Ladle hot broth over each portion. Top each bowl with small, separate mounds of zucchini, carrot, and shiitake, then finish with crumbled gim. Serve the soy-sesame sauce on the side so each person can season their own bowl. If the noodles have cooled too much during rinsing, briefly dip each portion in a strainer into hot water, drain well, and then add the broth.
Tips
- Choose the right soy sauce. Korean soup soy sauce has a lighter color and a saltier, more direct flavor than regular soy sauce. If it is unavailable, use regular soy sauce in the broth a teaspoon at a time and taste as you go; the broth will be darker and may taste a little sweeter. Keep the table sauce separate so you can adjust each bowl without over-seasoning the pot.
- Do not skip the cold rinse. Somyeon releases starch as it cooks. Rinsing under cold water washes that starch away and gives the noodles a cleaner, springier texture. Drain them well so they do not dilute the broth, and avoid cooking them far ahead because they can clump as they sit.
- Keep the vegetables fine and separate. Thin, similarly sized strips cook evenly and make the finished bowls look festive. Cook each topping just until tender, not browned or limp. If your skillet is small, work in batches; crowding the pan steams the vegetables and makes them watery.
- Adjust the broth gently. Dried anchovies and kelp can vary in strength, so taste the strained stock before adding extra salt. If it tastes too concentrated, add hot water a little at a time. If it tastes mild, simmer it uncovered for a few minutes before seasoning rather than pouring in a large amount of soy sauce.
Serving Suggestions
Serve janchi guksu immediately in warmed soup bowls, with the dipping sauce, extra sesame seeds, and extra crumbled gim on the table. The broth should be hot, while the noodles should be tender and distinct rather than swollen from a long soak. Put out small bowls of kimchi or another crisp, tangy Korean side dish if you like; its sharpness contrasts well with the mild stock and soft noodles.
For a celebratory spread, offer the soup as one course alongside a few small dishes rather than trying to turn every bowl into a large, heavily topped meal. The vegetables add color and texture, and each guest can control the salty sauce. If serving a crowd, keep the broth hot in a covered pot, cook noodles in batches, and assemble each bowl just before it reaches the table. That timing helps the noodles keep their pleasant bite.
Variations
Families and regions season janchi guksu differently, so the broth and garnish are not fixed to one formula. Some versions use beef stock or add thin strips of cooked beef; others feature an egg garnish, different vegetables, or a more assertive seasoning sauce. This recipe keeps the toppings vegetable-based and uses anchovy-kelp stock for a clear, savory flavor.
For a vegetarian broth, omit the anchovies and simmer the kelp with 5 dried shiitake mushrooms (about 15 g), the onion, and garlic in the same amount of water. Remove the kelp after 10 minutes and simmer the mushrooms and aromatics for 20 minutes, then strain. The result is earthy and less oceanic than anchovy broth; sliced rehydrated mushrooms can be added to the bowls. Use a vegetarian-certified soup soy sauce if needed.
For an egg garnish, beat 2 large eggs (about 100 g) with a small pinch of salt, cook them as a thin omelet in a lightly oiled skillet, and slice into narrow ribbons. The USDA FSIS safe minimum for egg dishes is 160°F (71°C); check the cooked omelet with a food thermometer before slicing. You can also add thinly sliced blanched spinach, mushrooms, or mild greens, keeping the toppings in separate piles for a traditional-looking presentation.
Storage and Reheating
For the best texture, store the broth, cooked toppings, and noodles separately. Refrigerate everything within 2 hours of cooking, in covered containers. The broth and cooked vegetables keep for 3 to 4 days in the refrigerator; cooked noodles are best within 1 to 2 days because they soften and stick together. Do not leave the finished soup at room temperature for more than 2 hours.
Reheat the broth on the stovetop until steaming, then bring it to 165°F (74°C) before serving leftovers. Warm the vegetables in the broth or briefly in a covered skillet. If noodles have clumped, loosen them under warm water and drain, or dip them briefly in boiling water; do not simmer them in the broth for several minutes. Assemble only the portions you plan to eat. Freeze broth separately for up to 2 months for best quality, but avoid freezing cooked somyeon, which tends to become soft and break apart.
Frequently Asked Questions
What is traditional Korean wedding food?
There are many foods served at Korean weddings, and menus differ by region, family, and occasion. Janchi guksu, a noodle soup, is a well-known celebratory dish often associated with weddings and long life. This recipe focuses on that soup rather than claiming it represents every wedding menu.
Why are noodles served at weddings?
The long strands of noodles are commonly associated with longevity and a long, happy marriage. Janchi means a feast or banquet, and guksu means noodles. The dish is also served at other celebrations, so it is not limited to weddings.
Where can I find somyeon and dried anchovies?
Look for somyeon, dried kelp, soup soy sauce, and dried soup-stock anchovies in Korean or other East Asian grocery stores. Somyeon is usually sold as thin, pale dried bundles. If you cannot find soup soy sauce, regular soy sauce works in a smaller amount, though the broth will be darker and have a different flavor.
Can I make the broth ahead?
Yes. Strain and season the broth, cool it promptly, and refrigerate it in a covered container for up to 3 to 4 days. Reheat it to 165°F (74°C) before serving. Keep noodles and toppings separate, and cook or warm the noodles close to serving time so they do not absorb the broth and turn soft.
Can I prepare the whole soup in advance?
You can prepare the broth, slice the vegetables, and mix the sauce ahead, but cook the somyeon and assemble the bowls just before eating. Cooked noodles continue to absorb liquid and lose their springy texture in soup. If you need to feed a group, keep the broth hot and bring the noodle water to a boil shortly before serving.
Is the dipping sauce meant to go into the soup?
Yes, but add it gradually. Start with a small spoonful in your bowl, taste, and add more if you want a saltier, more aromatic broth. Keeping it at the table lets people season their own portions and prevents the full pot from becoming too salty.
