Kongguksu is a popular summer dish made with soybean broth and noodles. I’m very excited to introduce this easy recipe to all of you!
I visited my cousin recently and she gave me her homemade soy milk.
It was more than delicious! I couldn’t help asking her secret recipe.
She usually doesn’t use noodles and drinks this every morning for her breakfast for years and years. I found her recipe was much simpler than mine! The secret ingredient that makes this drink very delicious is the mixed nuts. When all the ingredients for the broth are ground finely, it will look like foamy white milky liquid. Here’s the recipe!
Ingredients:
Dried soybeans, mixed nuts, water, ice cubes, skinned and roasted sesame seeds, thin noodles, salt, cucumber, tomato
- Wash and drain 1 cup of dried soybeans a couple of times and soak them overnight (8-12 hours).

- Drain the soybeans and put them in a pot.
- Add 2 cups of water and bring to a boil over medium high heat for 12-15 minutes.
- Rinse the cooked soybeans in cold water. Drain and put them into a large bowl.
- Scrub them with your hand to remove the skins.
- Pour cold water into the bowl and the skins will float to the top.
- Tilt the bowl and pour out the skins and water
- Scrub the soybeans some more, add more water, drain and remove skins several times until all the skins are removed.
- Put 1 cup of the clean soybeans into a blender.
*tip: Keep the rest of the cooked and cleaned soybeans in the freezer for future use. - Add 1.5 tbs of mixed nuts, 1 ts of skinned and roasted sesame seeds (optional), 1 ts salt, and 2 -2 ½ cups of cold purified water. Blend for 2 minutes.
- Add 4-5 cubes of ice and blend another minute until you get a soft, foamy, cold broth. Set it aside.
- Boil water in a large pot.
- Put noodles into the boiling water and stir them with a spatula. Close the lid and cook for a few minutes.
*tip: 120-150 grams of uncooked noodles per serving is a good amount. - Open the lid and check if the noodles are cooked properly or not.
*tip: Take a sample noodle and taste it. When you don’t feel any hard stuff as you chew it, it’s done. - Rinse and strain the cooked noodles in cold water a couple times.
- Put some noodles into a serving bowl and pour the soybean broth over them.
- Garnish with tomato and cucumber strips, and add more ice cubes if you want
*tip: 1 cup of dried soybeans will swell to about 2 ¼ cup when they’re soaked for 12 hours. I used only 1 cup of soaked and cooked soybeans in this recipe (the amount of broth could be used for 2 servings). You can make 5-6 servings with 1 cup of dried soybeans.
Enjoy my recipe!








































































Dear Maangchi,
Do you think that soybean powder would work just as well? I would boil it first then chill before adding the noodles. Also, what kind of noodle would be ideal?
I have never used soybean powder for this kongguksu, so I can’t give you the good answer. The noodles that I use for this recipe is here:

I do not like cold noodle. Could I have it hot instead?
My hot(temperature) noodle soup recipe will be posted someday in the future. The noodles for naengmyun is usually used for only cold noodles.
Hey, can i just buy the fresh soy milk from the market instead of doing it myself? Will it spoil the whole dish?
I don’t know the answer.
This soybean milk tastes different from the soy milk at the market. I don’t think it would work the same.
Thank you, Angie!
Where I live, the asian supermarkets often make their own tofu and soy milk. I noticed the chinese unsalted soy milk is the closest approximation to the taste of this recipe. Might need to doctor it up a bit (add some salt, etc.) to make it taste right though.
I am absolutely addicted to this dish. Everyday I wake up craving it xD
But I noticed that its a bit hard to eat if you put too much mixed nuts in it (like I do). Do most people strain their kongguksu before eating it? Or did I not blend it long enough?
Thank you so much for this recipe Maangchi! I never liked soy milk before, now I can’t get enough of it!
yes, you will have to blend it until it gets very soft (maybe 3 minutes?). Otherwise, it will be difficult for you to swallow. : )
Having soy milk in the morning is a very good habit! I’m happy for you!
What other dishes can you use the thin noodles in? My sister bought me a large bag of these noodles by accident and I’d like to use them as much as possible. Thank you!
For a quick meal, make the anchovy stock and boil with Dasima and onion. Cut up some ripe kimchi and add a little raw sugar to it and mix in a different bowl and put aside (Add the sugar to your taste). After the stock soup is done, only use the stock and add the noodles to it. Also add some of the kimchi and a Soy Sauce made for soup base to your taste. You can also add cooked korean squash (with a little garlic and salt for taste).
Another quick meal, is add soy sauce for soup base, sesame oil, and a little sugar to the noodles and mix. Then slice up some cucumbers or kimchi and add to it. I make this for my kids on a lazy day.
good suggestion! Thank you!
Wow, thank you.

I’m one of your followers also. Your site is really beneficial to us. Therfore, I’m so thankful to you because you’ve shared to us your easy recipes.

I hope to learn more tips from you. more power maangchi!

Hi Maangchi !
I really like this recipe for the summer. It helps me stay coool throughout the summer. It’s been really hot these days in Temecula !
Yes, as I mentioned on my blog, adding a little bit of mixed nuts was a secret to make this dish delicious! I learned it from my cousin very recently. I used to use only either pine nuts or roasted sesame seeds.
Hi Maangchi :)
I left you an award on my blog, you can pick it up if you’d like it’s okay if you don’t though since I know some bloggers don’t do awards since it’s time consuming or simply just don’t like it on their blog which is perfectly fine :)

The one and only time I’ve ever had this dish was when a friend of my mom’s prepared it one afternoon. I’d never had anything like it before…never even heard of it prior to that first taste. At first, I didn’t recognize it as soy milk. I honestly thought she had put the noodles in seasoned milk, until I realized the consistency (and to a degree the taste) was different. We ate ours with turnip kimchee.
I wish I could say that I really liked it, but it was just a bit too bland for my palate. I’m more of a spicy soup kind of girl, with the exception of myuk-guk..which I can eat gallons of.
It’s wonderful that you have it on your site though. My mom is a fan of this dish, so I’m grateful that I’ll have recipe to follow should she ever crave it.
maangchi, i made kongguksu today. SO GOOD! here are some photos of it. thanks so much, as always! :D
This recipe looks SOO delicious and I want to try it so bad but my husband doesn’t go in for cold soups!! I hope I can convince him to try it!
How wonderful! I am vegetarian and sometimes wish I could have naengmyeon in the summer, but this looks like a great alternative. This motivates me to buy a blender (mine has been broken for a while). I can make this and maybe even bindaetteok. Maangchi, do you think that I could use the first part of the recipe, where you make the soymilk, to make soymilk to keep in the fridge for drinking? Or do you have to drink it fresh out of the blender. Thanks, Maangchi!
Fresh drink is the best! Freeze individual portions of cooked soybeans in plastic bags or zip locks and make soy milk whenever you want. You can use milk instead of water. My cousin drinks it every morning.
Dear Maangchi,
The other day my mom bought home some soybean soup from the store. She said it was expensive and she was craving it.
After the noodles were all ready, my younger sister opened the refrigerator and the container with the soybean soup fell out and broke. It was tragic :[
I felt so bad I wanted to go to the place my mom bought the soup to replace it! But she wouldn't tell me where she bought it and came home the next day with a really bad tasting supermarket brand version of it.
I can't wait to try this recipe out! Everytime I make your recipes for my family, they really enjoy it :] They think I’m a really good cook =x
Thanks for everything Maangchi!
Your family must lo~ve soya milk! Wonderful! Homemade soya milk tastes much better than the soy milk in the store!
Maangchi: Here is another question. For lazy people like myself, can you use 2-1/2 cups unsweetened soymilk for a quick recipe?
ooh! I have never thought about making kongguksu with the store sold soya milk! I wouldn’t do that.
Hi Maangchi! Why do Korean girls have such nice skin? My sister-in-law tells me it’s the Korean diet. Is that true?
Thank you for posting this healthy recipe. I will give this a try with soba noodles.
Also, do you have a recipe for the Korean roasted corn tea?
maybe it’s the good bacteria in kimchi.
Hi Maangchi,
Have you ever heard of Korean brand “Livart”? I saw this nice mini mixer in Hanahreum Vancouver and have a hard time deciding whether to buy the set or the Magic Bullet. Maybe you’ve seen this product before. The color is green and it looks so much like the Magic Bullet. In case you know, can I use the mixer as a food processor and as blender at the same time? And is the quality good?
Thank you in advance, Maangchi. Thank you for sharing your recipes, too :)).
I don’t know about the brand name “Livart” or “Magic Bullet”. I should check it out when I go to a Korean store later.
Leave your question: http://www.maangchi.com/talk/forum/general-discussion
I think it’s going to be a good topic to discuss
I have the Livart blender you are describing and I love it! It’s made by LG and is very similar to the Magic Bullet, except the diameter of the Livart is smaller so the blender cups are not interchangeable. I personally think it’s cuter with it’s two-tone “creamsicle” look. My sister-in-law gave it to me and I use it to make smoothies and nutritional shakes.
As to the quality/durability of the Livart, I’ve had it for about 6 years and have never had any problems with it. When I’m on my “nutritional kick” (like right now) I use it every day. (Then at times I don’t use it for many months.) It blends ice cubes to a nice creamy consistency very quickly.
Right now I’m on one of my nutritional kicks again so I make a protein shake in the morning as my breakfast-on-the-go. For lunch I have another shake which I make at work with a regular blender. I noticed the blender doesn’t do as great a job on the ice cubes as the Livart. My co-worker is on the same “diet” and she has her Magic Bullet at work (that’s how come I know the cups are not interchangeable). They seem to work comparably, but I think the Magic Bullet is more expensive and has more options in accessories (like a full-size blender container, a juicer, etc.) which the Livart doesn’t have. Because I didn’t buy it, I’m just guessing that it’s less expensive than the Magic Bullet.
Hope this helps!
Hello!!
Its So easy I m 105% Sure I will Make This
But Can I Use Naeng Myun Instead Of Guksu noodles
?
oh, no, no, no! : )
Naengmyun noodles don’t go with this dish.
Very nice with this weather, i love the big smile at the end :}
wow!! looks so good, i can’t wait to make this. i even have some soybeans lying around the pantry, all i need is those noodles. is it okay to use brown soba noodles?
hmm, good question! I always use white and thin noodles for this recipe, but you could use brown soba noodles,too. why not!
Brown Soba noodles are a healthy alternative to the white, thin noodles. I’ve tried both, and personally prefer the white, thin noodles. The white noodles absorb the taste of the soybean soup whereas the brown soba noodles don’t quite do the same.
Maangchi, your website is great and I highly recommend your website to all my friends back in Cali.
Maangchi! I love your videos. Since i found you on youtube, i’ve been HOOKED! I’m korean myself and LOVE COOKING and i’m so glad i found you, now i can cook korean food more often!! kong gook su is my favorite summer food. now i can make that at home. thanks!!
I’m so glad to be found by you! lol!
Hi Maangchi, you are so cute:), thank you to post so many recipes, they are unbelivable good…
Thank you!
Are the mixed nuts salted or unsalted? Since you add salt anyway, I guess it may not matter (if you adjust the salt to suit), but I’d still like to make it properly.
They are salted. I bought it from Costco.
