Janchi Guksu (잔치국수): Korean Banquet Noodle Soup with Anchovy Broth

Janchi guksu is the kind of Korean noodle soup that feels both humble and celebratory. The name literally means "banquet noodles," a nod to its history as a dish served at weddings, birthdays, and other gatherings where long noodles symbolized a long, happy life. These days it's just as common at the lunch table on a quiet weekend.

What makes it special isn't complexity, but balance. A clear anchovy and kelp broth carries thin somyeon noodles, while colorful garnishes like egg jidan, sautéed zucchini, shiitake, and carrot turn a simple bowl into something that looks like it took far more effort than it actually did.

If you've ever felt intimidated by Korean noodle soups, this is a perfect starting point. The broth comes together in about fifteen minutes, the garnishes can be prepped while it simmers, and a small bowl of seasoning sauce on the side lets each person adjust the flavor to taste.

Below is a full home-style version of janchi guksu, the Korean banquet noodle soup, with everything you need from broth to plating.

What Makes Janchi Guksu Special

Janchi guksu sits at the gentle end of the Korean noodle spectrum. Unlike spicy bibim guksu or hearty kalguksu, this dish is built around clarity and lightness. The broth is clean and subtly briny, the noodles are delicate, and the garnishes add color, texture, and just enough richness to make the bowl feel complete.

The dish is also incredibly forgiving. You can dress it up with the full set of garnishes for guests, or strip it down to broth, noodles, and a quick egg ribbon when you want something fast. Either way, the soul of the dish stays the same.

The Anchovy and Kelp Broth (Myeolchi Yuksu)

The broth is the foundation. Traditional myeolchi yuksu relies on dried anchovies and dried kelp, which together create a deep umami base thanks to the natural synergy between the inosinates in the anchovies and the glutamates in the kelp. If you've ever wondered why this broth tastes so satisfying despite having so few ingredients, that's the science behind it.

You can use a pre-made Korean broth pack (which usually combines anchovies, kelp, and dried seafood) for convenience, or build the broth from scratch with a small handful of large dried anchovies and a piece of dried kelp. Both methods deliver a clear, fragrant stock that's the backbone of janchi guksu.

Ingredients (Serves 2)

For the broth

• 1 Korean broth pack (anchovy, kelp, and dried seafood), or a small handful of large dried anchovies plus a 4-inch piece of dried kelp
• 1 liter (4 cups) water
• 2 tablespoons Korean tuna sauce (chamchi-aek), or substitute with 1 extra tablespoon soup soy sauce
• 1 tablespoon Korean soup soy sauce (guk-ganjang)

For the seasoning sauce (yangnyeomjang)

• 2 to 3 tablespoons finely chopped green onion
• 5 tablespoons regular soy sauce (jin-ganjang)
• ½ tablespoon sugar
• ½ tablespoon minced garlic
• 1 tablespoon toasted sesame oil
• 1 tablespoon apple juice or pear juice
• A pinch of toasted sesame seeds

For the garnishes

• ⅓ medium zucchini, julienned
• 1 large shiitake mushroom, thinly sliced
• A small piece of carrot, julienned
• 2 tablespoons cooking oil
• A pinch of fine salt
• 2 large eggs
• 1 to 2 sheets of roasted seaweed (gim), cut into thin strips

For the noodles

• 2 portions (about 160 to 180 g) somyeon (thin Korean wheat noodles)

All measurements use standard tablespoons.

Instructions

1. Make the broth. Pour 1 liter of water into a pot and add the broth pack (or dried anchovies and kelp).

   
   Stir in the soup soy sauce and tuna sauce. Bring to a rolling boil, then lower the heat to medium-low and simmer for 10 minutes.
   
   
   Keeping the heat gentle prevents the liquid from reducing too quickly and keeps the broth clear.

2. Prepare the egg jidan. Crack the eggs into a bowl and beat well. No salt is needed since the seasoning sauce will add flavor later.

   
   Heat a wide pan over high heat, pour in the egg, and immediately reduce the heat to low. Cook slowly until just set, flip briefly, then slide onto a plate. Let it cool completely before slicing into thin strips so it holds its shape.
   

   

3. Sauté the vegetable garnishes. Heat the cooking oil in a pan over medium-low heat. Add the zucchini, shiitake, and carrot with a pinch of salt.

   
   
   Cook gently for just a few minutes until the vegetables are tender but still have a little bite. Don't overcook them, as their fresh texture is part of the charm.
   

4. Mix the seasoning sauce. In a small bowl, combine the chopped green onion, soy sauce, sugar, minced garlic, sesame oil, apple or pear juice, and sesame seeds.

   
   Stir well. For a spicier version, add a small spoonful of Korean red pepper flakes (gochugaru). Any leftover sauce keeps in an airtight container in the fridge for about a week and works beautifully on rice, tofu, or other noodle dishes.
   

5. Cook the somyeon. Bring a large pot of water to a rolling boil. Add the noodles and cook for about 3 minutes, stirring once or twice.

   
   
   For a firmer bite, pull them slightly early; for a softer texture, give them an extra 20 to 30 seconds.
   
   
   Adding a splash of cold water to the pot once or twice during boiling helps the noodles stay springy.

6. Rinse and drain. Drain the noodles and rinse under cold running water, rubbing gently to remove excess starch. Shake off the water in a colander. A little remaining moisture is fine.

   

7. Plate the bowls. Twirl the noodles into a neat mound in each serving bowl so the garnishes have a stable base. Arrange the sautéed vegetables, egg strips, and seaweed strips on top.

   

   

8. Pour and finish. Ladle the hot broth gently around the noodles. Sprinkle with a little extra sesame seed. Serve the seasoning sauce on the side so each person can drizzle to taste.

   

Flavor and Texture Notes

The first sip should taste clean and slightly briny, almost like a refined seafood consommé. As you stir in a spoonful of seasoning sauce, the broth deepens into something rounder and more savory, with little hits of garlic and sesame.

The noodles themselves are soft but bouncy, while the vegetables add a gentle crunch and the egg adds a soft, buttery layer. Roasted seaweed brings a subtle smokiness that ties everything together. It's a quiet dish, but every element pulls its weight.

Tips, Variations, and Serving Suggestions

For a heartier bowl, top the noodles with a generous spoonful of finely chopped kimchi. The acidity cuts through the broth beautifully and adds a punch of flavor without overpowering the dish.

If you prefer chewier noodles, swap somyeon for jungmyeon (medium-thickness wheat noodles) or even fresh kalguksu noodles. Cooking times will vary, so follow the package instructions.

Janchi guksu is light enough to pair with almost any Korean side. A small plate of crisp cucumber muchim, quick-pickled radish, or a simple banchan rounds out the meal without competing with the broth. If you want another noodle dish in your rotation, our recipe for bibim guksu offers a spicy, cold counterpart that uses many of the same pantry ingredients.

For an even quicker weekday version, skip the sautéed vegetables and simply swirl a beaten egg into the simmering broth just before serving.

Frequently Asked Questions

What does janchi guksu mean and why is it called banquet noodles? "Janchi" means feast or banquet in Korean. The dish was traditionally served at weddings and milestone birthdays because the long noodles symbolized longevity and lasting happiness. Today it's served year-round as a comforting everyday meal.

Can I make the anchovy broth ahead of time? Yes. The broth keeps well in the refrigerator for up to 3 days in a sealed container, and it actually tastes a little more rounded the next day. Reheat gently on the stove before serving.

What's the difference between janchi guksu and kalguksu? Janchi guksu uses thin, dried somyeon noodles in a clear anchovy-kelp broth with light garnishes. Kalguksu uses thick, hand-cut wheat noodles, often in a richer broth made with seafood or chicken. The textures and overall feel are quite different.

Do I need the seasoning sauce, or can I skip it? You can absolutely enjoy the bowl with just the broth, especially if you've seasoned it well during simmering. The seasoning sauce adds extra depth and a touch of garlic-sesame richness, so most people drizzle in at least a small spoonful.

Why are my somyeon noodles mushy? Somyeon cooks very quickly, usually in around 3 minutes. Overcooking or skipping the cold-water rinse are the two most common culprits. Rinsing washes off surface starch and stops the cooking, which keeps the noodles springy.

Bring the Banquet Home

Janchi guksu proves that a few simple ingredients, treated with care, can produce one of the most satisfying bowls in Korean cooking. Once you've made the broth and seasoning sauce a couple of times, the whole dish comes together almost on autopilot.
