Summer is a great season to make quick Korean cucumber kimchi – a popular summer side dish (banchan) in Korean cuisine. If you have not tried, I urge you attempt. You will soon learn why so many people are getting hooked on kimchi made with cucumbers.

I have to tell you that the crunchiness of this traditional cucumber kimchi stands out among all other cucumber kimchi recipes.

Why you’ll love this recipe

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 recipe for cucumber kimchi! 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 authentic 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.

Store cucumber kimchi in an airtight container.

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 traditional stuffed cucumber kimchi recipe. It’s the way an authentic cucumber kimchi should be, and it’s easy to make.

What cucumbers to use

Good cucumber kimchi should start with a right type of cucumber. Below are the cucumbers suitable for making stuffed cucumber kimchi:

  • Korean cucumbers: Long and slim with pale green color. Very crunchy! Most Korean grocery stores carry them throughout spring and summer.
  • Kirby cucumbers: Widely used as pickling cucumbers and available anywhere.
  • English cucumbers: Tender skin makes them suitable for making kimchi. Widely available.

I chose Kirby cucumbers this time. Kirby cucumbers are great for making cucumber pickles, which maintains the same crunchiness.

Cucumber kimchi filling

  • Asian chives – You can substitute with green onion
  • carrot – adds more texture and taste
  • onion, garlic, ginger paste – savory addition
  • Korean fish sauce or other fish sauce
  • Korean chili flakes (gochugaru)
  • sugar – provides sweet balance in kimchi
  • Korean plum extract (optional) – it adds another layer of sweetness but omittable.
  • water and salt – to brine the cucumbers. Use coarse sea salt (Korean salt preferred)
This cucumber kimchi maintain its crunchiness without going mushy.

Recipe Success Tips

  1. 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.
  2. 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.
