Cold cucumber soup side dish

Oi naengguk 오이 냉국

Oi naengguk is another simple but popular Korean side dish, perfect for summer. I have made so many different kinds of naengguk (cold soup) using different vegetables, but this is my most favorite recipe. The seasoning in this recipe could be changed a little according to your taste, more sugar if you like it sweeter, or more chili peppers if you like it spicier.

Ingredients: Cucumber, garlic, green chili pepper, red hot chili pepper, green onion, vinegar, salt, fish sauce, sugar, sesame seeds, water, and ice cubes.

  1. Get a bowl that can hold more than 2 cups.
  2. Cut 6 oz (170 grams) of cucumbers into 1½ cups’ worth of matchsticks and add to the bowl.
  3. Mince one clove of garlic and chop up a green onion and a green chili pepper. Add them to the cucumber strips in the bowl.
  4. Add 1 ts of salt, 1 ts of fish sauce, 1½ tbs of vinegar, 2 ts of sugar to the bowl and mix it well with a spoon.
  5. Pour 1½ cup of cold water (purified or boiled and cooled down) to the bowl and mix it.
  6. Add 6-7 ice cubes.
  7. Cut some red hot chili pepper for a garnish and sprinkle over the top of the soup with sesame seeds.
  8. Serve it with rice.

You can also make naengguk with miyuk (sea plant), or egg plant, instead of cucumber. Or you can make it with mi yuk (sea plant) together with cucumber, too. You can try some different combinations to see what you like the best.

My best friend’s mother–in-law had major surgery that caused her to stay at the hospital for months. When she got out of the hospital, my friend asked, “Mom, what do you feel like eating now that you can eat any food that you want? I would like to make your favorite food, something you couldn’t eat for months!”

The mother-in-law said, “I don’t have any food that I feel like at the moment except for oi naengguk”. My friend expected her mother–in-law to say that she wanted some expensive gourmet food, but all she wanted was simple “oi naengguk”!

After meeting my friend on the day, what do you think I did when I came back home? Haha, I made a huge bowl of oi naengguk and enjoyed it, thinking about the mother-in-law. Whenever I eat oi naengguk, it reminds me of my friend’s mother-in-law.

Yes, we don’t always have to have expensive luxurious gourmet food, sometimes very humble food makes our lives happy.

    Hi Maangchi, you say that it is also possible to make this recipe using eggplant. Do you need to cook the eggplant or soak them in salty water or anything before following the cucumber recipe?

    I know this is crazy late, but I was watching “Happy Together” and a dish was made using cold cucumber soup. If I were to make this a day or two in advance, how long does it stay in the fridge? Sometimes it gets so hot here that it would be perfect after I get done at the book store. Thank you for your recipes!

    Hi Maangchi!
    I’m glad you liked gazpacho! It’s one of my favorite meals in hot days. I think cold soups is one of the things we have in common in Korea and Spain. I’ll try this recipe as soon as possible, it’s starting to get very hot here in Madrid!
    Greetings from Spain.

      I tasted gazpacho soup for the first time when I travled to Portugal and fell in love with the soup. After Portugal, I went to Spain and I ordered the soup whenever I went to a restaurant. It was hot summer days. Delicious!

    You make it look so easy – especially for an inexperienced chef like me – and yet… it IS easy! Have been waylaid with a stomach virus and all I can eat is soup, and this sounded like such a wonderful change. Just made a batch for tomorrow (to chill overnight in the fridge), and even before it’s cold it tastes good! I omitted the chilli (both red and green) as I thought it might upset my stomach, but added a bit more green onion. Can’t wait for tomorrow now! Thank you so much Maangchi… am off to look at the next recipie of yours I can try! :)

    Great summer dish for the hot weather. There wasn’t any red chili at the market so I used a sweet red pepper and it worked very well. Off topic- Oi means cucumber, right? Is it also a name? I have been watching Jumong and there is a character named Oi. Is his name cucumber?

      yes, I sometimes use red bell pepper in my oinaengguk, too. My Thailand friend’s name is oi, too. I tease her,”Cucumber, where have you been!” : )

    Hi Maangchi,

    It is very hot and humid right now where I live. I’ll definitely make this cold soup to beat the heat! Usually my mom makes an Indian cucumber and cilantro salad with some authentic seasonings but this looks so tasty to!!! Thanks

    Thank you so much for this recipe. My mother, who is usually very critical of my cooking, just came home for a visit. I knew she liked cold soup and had a couple of pickling cukes laying around. Whipped this up in no time (added just a scootch less sugar b/c she doesn’t like anything tasting remotely sweet) and served it up. I had been tempted to add more vinegar b/c I’m a vinegar fiend, but I made myself follow everything else to the tea and…..she loved it! Made three comments about how good it was while we were eating. We had other (storebought) banchan on the table, but she ate almost nothing else but her rice and this soup. It felt good to do something for her that she enjoyed.

    Hey Maangchi!
    I’ve made this recipe 2 times before. The first time I used cucumbers, and the second time, I substituted the cucumbers for seaweed. It’s okay that I didn’t cook it right? Eating raw seaweed is okay as long as I washed it well right? o.O
    Anyways, I plan on making this again with both seaweed and cucumbers. The last time I made it, my dad finished all of it! He was surprised when I told him that I made it ;]
    Thanks for this recipe~ I’ll be looking forward to your next recipe that you will share with us!

    My family loves your oi-naengguk! My husband is pretty picky about his Korean food and he thought this would be good enough to sell at a restaurant. I also made your naeng-myun this week, and my family loves oi-naengguk so much we use that for mul naeng-myun broth. It’s delicious!

    Hello Maangchi,

    I was practicing driving a stick shift with an empty stomach and no A/C (need to listen to the engine), I was ‘overheated’ that I felt dizzy and my heart of beating rapidly. (>100 degrees here in Arizona)

    I made Oi Naeng guk for supper. It was so refreshing and cooled my body down. I reduced the vinegar into 1 tbs, since I cannot endure much sourness.

    I pre-chopped the garlic and preserved them in oil once the garlic arrived home.
    The oil which sticks to the minced garlic floats on the surface of the naeng guk, which I don’t think it’s pretty. Therefore, I did not take a picture of it.

    I enjoyed the naeng guk, and I’d like to thank you for the recipe.

      I would use 1 ts of hot pepper flakes.
      Mix it well with other ingredients before pouring water into the bowl

    I had some leftover oi naengguk in the fridge, but my wife accidentally put it in the blender! :O It was still very good, though. I think I may even like it better.

    I just made the cold cucumber soup and it was excellent not to mention a very fast dish. I love cold sour soups. I frequent a Korean restaurant in the Chicago area called Woo Lae Oak. They often have a cold radish soup that is a clear salty and sour liquid with daikon radish. I love it. Can’t seem to find a recipe for this soup anywhere. Do you have one?

    Thanks for the great recipe! Jon

    I made galbi tonight and made this soup to go with it. It was FANTASTIC! I haven’t had this since I left Korea 6 years ago, but it was just as I remembered. Excellent recipe! Thank you so much. I enjoy all of your recipes and videos and am so grateful to you for all the work you do here! (^o^)

    Hi Maangchi I just wanted to let you know that I tried this recipe for the first time today and it was delicious the recipe calls for two servings but I found myself eating the whole thing hehe. The flavour reminded me of vietnamese cuisine. I love all your recipes and your videos. Korean food has always been fascinating to me and thanks to your help I can now cook korean right at home for my family! Thanks Maangchi :)

    I know it’s winter now, but it was a sunny warm day today, and I was doing some gardening. I made this soup, because I needed something refreshing and spicy to pick me up! I added extra red chilly flakes, and it was good!!!

    Keep up the good work Maangchi! Kisses from sunny Athens/Greece!

    Hi Maangchi! I love to see your cooking videos. You make korean cooking very easy for me^^, At first, I thought preparing korean dish is quite difficult but it’s not. Thanks to you^^,
    bdw, I wonder how would I prepare the eggplant for naengguk. Do I have to boil the eggplant and add it to naengguk or it’s just fresh eggplant?
    Again, congratulations for a job well done Maangchi!^^,

    tha,
    oh, the cucumber side dish you had is very easy to make.
    Slice English cucumber thinly and sprinkle some salt. Remove water from the salted cucumber 10 minutes later and squeeze it slightly. In a bowl, put some minced garlic, hot pepper paste and powder, vinegar, sugar and mix it. Then add the sliced cucumber to the bowl and mix it. Sprinkle some sesame seeds and sesame oil.
    My cucumber side dish doesn’t use vinegar. I will post the recipe someday later.

    The recipe for fish cake side dish will be posted later, too.

    Thanks a lot!

    Hi Maangchi! I love your website!!

    I’m just wondering if you knew the recipe for making a side dish that I see a lot in Korean restaurants. The side dish is cucumbers and it’s sweet and also has red spicy sauce. I think it’s with vinegar and sugar. I keep trying to find the recipe online but I only find the recipe for KIMCHI CUCUMBER, which is NOT the same.

    Also, I love the fishcake that they often serve with the above mentioned side dish. Do you have any recipes for those? Thank you!!! keep up the great work!

    This reminds me of my moms cooking, there’s a thai salad called ” Som tum taeng” using cucumbers it’s the same way to make “oi neanggkok” but you shred the cucumbers and don’t add water or ice cubes.

    Cloud,
    You remind me of one of my blog readers. She said she has changed her diet to Korean food since she found my cooking videos on the internet and lost 75 pounds! I didn’t ask her weight though. : ) Anyway, you asked me to recommend healthy and low cal dish. Why don’t you make seaplant soup (miyuk guk in Korean ) My mother loves the soup. She makes it at least twice a week!

    Wow, will try this next time :D Sounds like a low-cal dish, haha. Maangchi, could you recommend me some low-cal dishes I could cook during a diet? I just got interested in Korean cooking, but I really need to lose some weight -_- 제발요~

    I made this in a bad mood today – and now I’m in a good mood! Unfortunately, I was in a pinch. I had to substitute the hot red pepper with red pepper flakes and the green pepper with a couple of chopped green olives. It ended up tasting like olives ^_^ Not bad, overall~~ At least it looked okay!

    …and no one can tell now that I’ve ate it all *ha!ha!*

    I promise I’ll try this with eggplant some time.
