What is Korean cucumber salad?
The Korean cucumber salad, known as oi muchim (오이무침), is a cherished side dish, or banchan. ‘Oi’ means ‘cucumber’, and ‘muchim’ is a traditional method of hand-tossing vegetables with seasonings.
This salad is especially favored during summer and has gained global appreciation in recent years.
A typical recipe involves thinly sliced cucumbers mixed with a tangy and mildly spicy dressing. The dressing combines soy sauce, vinegar, Korean chili flakes, sugar, garlic, and green onions.
However, this version of the recipe offers a unique twist. By adding a hint of gochujang, a flavorful Korean chili paste, the salad acquires a deeper umami taste. Try this recipe for a special variation on a classic dish.
Ingredients for Making a Perfect Korean Cucumber Salad at Home

- Most people commonly use rice vinegar, but if it’s not available, white vinegar makes a good substitute.
Note: If you only have the waxy American cucumber available, you should peel off its skin. The thick and fibrous skin.
Can I use a different type of cucumber for this recipe?
Absolutely, while the traditional Korean cucumber salad is made using Korean cucumbers, which are thin-skinned and have fewer seeds, you can certainly use other types of cucumbers.
English cucumbers or Kirby cucumbers are a good alternative due to their thin skin and minimal seeds. If you only have regular, garden variety cucumbers available, they can work too, but you may want to peel them as their skin can be tougher, and consider scooping out the seeds if they’re too abundant.
The key is to slice your cucumbers thinly so they can fully absorb the flavors of the dressing.

Essential Recipe Tips
To achieve the best results for your cucumber salad, I recommend the following two tips:
- Lightly salt the cucumber slices for 5-10 minutes to draw out excess moisture. Doing so maintains the cucumbers’ crispness and prevents the seasoning from diluting once the salad is tossed.
- Add a small amount of Korean chili paste (gochujang) alongside Korean chili flakes (gochugaru). Gochujang adds thickness to the seasoning, allowing it to better adhere to the cucumber slices.

Sprinkle 1/2 teaspoon of salt over the thinly sliced cucumber and toss to coat. Let it sit for 5-7 minutes until the salt draws out the excess moisture. Drain the cucumber slices to remove the liquid.
Step 2: Toss with the dressing ingredients
- Add the thinly sliced onion, Korean chili flakes, Korean chili paste, vinegar, garlic, sugar, Korean soup soy sauce, sesame oil, toasted sesame seeds.

- Start tossing the cucumber all together until cucumber slices are well coated with the seasoning. Taste and add more salt if needed
Traditional tossing technique: The age-old Korean technique of tossing vegetable salads by hand, called muchim, is used to create a variety of flavorful side dishes.
