Homemade Korean Cucumber Kimchi (Oi-Sobagi)
In this post, I teach you how to make cucumber kimchi (oi-sobagi), which is an essential summer kimchi in Korean cuisine. This authentic kimchi recipe is easy to make at home. The stuffed cucumber kimchi ferments well and retains its crispness all the way through. Step-by-step instructions and video included.
Summer is a great season to make quick Korean cucumber kimchi – a popular summer side dish (banchan) in Korean cuisine. I have to tell you that the crunchiness of this traditional cucumber kimchi stands out among all other cucumber kimchi recipes.
Not all cucumber kimchi recipe is created equal. Sure, they all start out with a crisp texture at the beginning. However, as the kimchi ferments, it tends to lose its crunchy texture, and sometimes the kimchi becomes mushy.
But not with this cucumber kimchi recipe! You can maintain the crunchiness all the way through even after the kimchi becomes very fermented. You will enjoy every bite of this delicious kimchi until you finish the entire batch. That’s the way Korean kimchi recipes should be.
- Korean names for cucumber kimchi: Stuffed cucumber kimchi is called “Oi-sobagi (오이 소박이)”, and the cut-up cucumber kimchi is called “Oi Kimchi (오이김치)”. Which will stay crunchier longer? Definitely the Oi-sobagi.
Cucumber kimchi vs cucumber salad
I noticed that many people, even some food bloggers who posted cucumber kimchi recipes on their sites, are confused with cucumber kimchi with Korean cucumber salad (Oi-muchim). They are not the same and made completely different. Korean cucumber salad is a quick side dish and it is not intended to be fermented.
Why you should stuff cucumber kimchi
Stuffing cucumber with kimchi filling keeps the cucumber intact and locks in its texture and flavor. It helps the cucumber to ferment slowly creating better tasting kimchi — the traditional way of making cucumber kimchi.
It is almost like having spicy cucumber pickle, but in Korean taste!
The cut-up cucumber makes a quick kimchi and it is easier to prepare, but it ferments faster and often becomes mushy quickly. If you wish to consume your cucumber kimchi within a few days, it doesn’t really matter whether to stuff it or cut it up.
However, if you prefer to enjoy the real crunchy and full-bodied flavor, go with stuffed cucumber kimchi recipe. It’s the way an authentic cucumber kimchi should be, and it’s easy to make.
My cookbook, “Korean Cooking Favorites”, will share other interesting yet authentic Korean kimchi varieties. Also, don’t forget to check my different types kimchi recipes for more easy homemade kimchi ideas.
The cucumbers suitable for making stuffed cucumber kimchi are:
- Korean cucumbers
- Kirby cucumbers
- English cucumbers
I chose Kirby cucumbers this time. Kirby cucumbers are great for making cucumber pickles, which maintains the same crunchiness.
Other ingredients you will need are:
- Asian chives – You can substitute with green onion
- ginger puree
- Korean fish sauce or other fish sauce
- Korean chili flakes (gochugaru)
- Korean plum extract (optional)
- Use salted boiling water — Most cucumber kimchi recipes use plain salt or cold salted water. That works fine and makes good tasting kimchi up to the early stage of fermentation. However, using boiling water locks in the texture of kimchi longer.
- Would the boiling water cook the cucumbers? — Not really. It definitely softens the skin of the cucumber, and helps them lose their stiffness faster, but the boiling water will also help the salt penetrate into the cucumber faster and keeps them crunchy longer.

How to make Cucumber Kimchi
How many cucumbers to use? It depends on the type of cucumbers — 8-10 for Kirby cucumbers, 5-6 for Korean cucumbers, or 4 for English cucumbers.
Cut through a cucumber in a cross pattern, but leave one end of the cucumber uncut.
Combine water and salt; bring to boil. Pour the boiling salted water over the cucumbers in a mixing bowl.
Put a weight on top of the cucumbers so that they stay immersed in the salt brine. Let them sit for 1 hour, then drain.
Cut Asian chives into 1 to 1 1/2-inch long pieces.
To make the kimchi filling, mix together the Asian chives, carrot, onion, garlic, ginger puree, Korean chili flakes, Korean anchovy sauce, sugar, Korean plum extract (optional), toasted sesame seeds, and water in a mixing bowl.
Stuff the cucumber with the kimchi filling, coating the outside of the cucumber with the filling as well.
Stack the stuffed cucumber kimchi in an airtight container and cover.
