What is janchi guksu?

Janchi guksu (잔치국수) translated into “banquet or feast noodles,” is a simple warm noodle dish made with thin wheat noodles (소면, somyeon or somen) that are usually served in a clear anchovy or beef broth. Because noodles symbolize long and happy lives in Korean culture, this noodle dish is traditionally served alongside other special occasion foods at large feasts such as weddings. The name of the dish comes from that tradition.

In my family, this is another easy go-to meal when we crave something warm and light. It is one of the most frequently requested meals by my daughter when she comes home.

Broth for janchi guksu

The most important part of this humble noodle dish to me is the broth. You can of course use any broth, but anchovy broth is typical. Anchovy broth can be made simply with dried anchovies and kelp. Some vegetables, such as Korean radish, onion, and or dried shiitake mushrooms, will add more depth to the flavor of the broth. See my Anchovy Broth for Korean Cooking for options.  

You can use beef broth, vegetable broth, or chicken broth instead if preferred. Refrigerate or freeze any leftover broth to use at another time for making jjigae or gyeranjjim.

Toppings for janchi guksu

You can practically use any number and combination of vegetable or other toppings for this soup, making it as fancy or minimal as you want. Common toppings for this noodle soup include vegetables such as zucchini, carrot, and/or kimchi.  Thin strips of tender beef, eomuk (fish cake) and roasted gim (dried seaweed) are also popular additions. 

Recently, this noodle soup appeared in the popular Korean drama, Crash Landing on You (사랑의 불시착). I loved everything about this drama! Due to a paragliding accident, a South Korean woman CEO makes an emergency landing in North Korea, where she meets a North Korean army officer. The story line is unique with a nice balance of romance, comedy, and action. It was fascinating to see every day life in North Korea and hear their dialect.

As for this dish, the mother of the North Korean officer served the young woman from the South with a simple yet elegantly prepared noodle soup. It was a small serving of this noodle soup with minimal toppings, simply with strips of mushrooms, carrot, zucchini and egg garnish (jidan). I tried to recreate it in the first photo. 

This recipe shows 4 toppings and other optional topping possibilities. Feel free to pick and choose any number or combination of them. 

You can serve this noodle soup with a spicy soy sauce based sauce (yangnyeomjang). However, you don’t absolutely need it. I like it without the sauce because I enjoy the clear and refreshing broth.

  • Bring a medium pot of water to a boil. Cook somyeon noodles according to the package instructions (about 3 minutes). Drain quickly and shock in cold water to stop cooking.

  • Place the noodles in serving bowls. Ladle the hot broth over the noodles to cover all the noodles, and pour it back to the pot by holding the noodles with the ladle. This will warm the noodles. Ladle the hot broth over the noodles again. Nicely arrange a small amount of each topping on top of the noodles. Finish the dish off with a sprinkle of the optional chopped scallions. Serve warm with the optional sauce on the side.
