Korean Noodle Soup (Janchi Guksu)

Noodle soup is a perfect comfort food in cold weather. Try this easy Korean noodle soup recipe. The soup is savory and refreshing, and tastes a bit like kalguksu (Korean knife cut noodles). This Korean noodle soup also makes an easy one bowl meal for any time of the day!

Today I want to introduce a Korean noodle soup – Janchi Guksu recipe.

What is Janchi Guksu?

Janchi guksu(잔치국수) translates to banquet noodles or festivity noodles. Its name originates from the Korean custom of having this warm noodle soup on celebratory occasions such as wedding receptions and 60th birthday parties in Korea.

Having these long thin guksu (noodles) symbolizes wishing for long life. But also wheat flour used to be a luxury ingredient in the old days of Korea, so it was considered a party worthy food for the guests.

How is Janchi Guksu Made

Essentially, briefly boiled long thin somyeon noodles (소면, somen) are served in a bowl of Korean soup stock. This soup stock can be made with beef briskets or dried anchovies (& dried kelp). Nowadays it is more common to make it with the latter ingredients, so in this recipe, I used dried anchovies and dried kelp as a soup base.

(Note – You might notice that the soup quantity is quite a generous amount, which might be even enough for 3 servings. But I love replenishing my bowl with the soup as I eat the noodles, so you might want to do the same. ;))

The noodle bowl also presents a few varieties of vegetable toppings. Contrary to the fancy sounding name, the toppings are quite modest. Most commonly used are julienned carrots and zucchinis.

I also listed a few popular topping ingredients below, so you can pick and choose based on your preference and dietary needs.  (Find these below under the heading “Alternative or Additional Toppings”)

Finally, there is a seasoning sauce that goes with it. You don’t have to serve with it, but it’s always nice to have more serving options for those who like a stronger flavoring.

I think that is it! Now it’s your turn.

Hope you like my recipe! And, if you try this, let me know how you go with it in the comments below.

How to Make Korean Noodle Soup

1. Preheat a skillet/pan over medium low heat. Add some cooking oil and spread it around the pan. Add the beaten eggs and cook it like an egg omelette. When both sides are cooked, transfer it to a cutting board. Gently fold / roll up the egg omelette and thinly slice it. Set it aside.

6. Serve the noodles into a soup bowl (you may want to use tongs if the noodles are still hot) and garnish with the egg, zucchini, and carrots. Add the boiled stock (from step 4). Serve warm immediately. Add the seasoning sauce as needed.

Make-Ahead Tips

You can prepare everything ahead of time except for the noodles themselves. The most useful thing to make ahead would be the soup stock!

You can keep it in the fridge for several days or even freeze it for a month or two. It’s very handy to have if you make many Korean soup dishes.

If you make ahead, just keep all ingredients in a separate container. Prepared vegetables should be OK for a few days and the seasoning sauce for a week or two, in the fridge.

  1. I love it tho’. I have this noodles from the shop in Ulsan back in 2012 when my family was living in Ulsan Korea. I really love this receipe.
    I miss Korea so much.

    Thank for sharing your receipe.

  2. Hello Sue, thank you sharing this recipe. I made this noodle soup last month. This is my kind of diet and I really like how simple it is, though people with strong taste buds might argue that it a bit bland. I think the secret of this noodle soup lies in the seasoning sauce 😉 It is sooooo good!

  3. Late January, early February tend to be the coldest time of the year in Hawaii. It’s a chilly 65 degrees F right now so guksu is perfect for this time of year. The difference between your recipe and mine is that I don’t cook or even blanch the julienned carrots and I prefer julienned cucumber. The hot broth will cook the veggies enough. My wife likes a lot of chopped green onions on top. A couple of mandu in the broth complete this dish for a filling, satisfying meal.
