If you have ever eaten at a Korean restaurant, chances are you have seen this bright, refreshing cucumber salad show up as one of the little side dishes.
This spicy Korean cucumber salad, also known as oi muchim, is one of the easiest and most addictive Korean banchan you can make at home.
Crisp cucumbers are lightly salted, then tossed with garlic, sesame oil, soy sauce, and Korean chili flakes to create a salad that is fresh, garlicky, slightly spicy, and packed with flavor.

This dish is perfect alongside rice bowls, grilled meats, Korean BBQ, or even simple weeknight dinners when you want something light and refreshing on the table.
What Is Oi Muchim?
Oi Muchim (오이무침) is a classic Korean side dish made with cucumbers that are salted, seasoned, and lightly marinated with garlic, sesame oil, chili flakes, and soy sauce.
In Korean cooking, dishes like this are called banchan, which are small side dishes served with rice and shared at the table. Oi muchim is especially popular because it is:
Quick to make
Refreshing and crunchy
Perfect for balancing rich foods like BBQ or braised meats
The combination of spicy, savory, and nutty flavors makes this simple cucumber salad surprisingly addictive.
Why This Korean Cucumber Salad Works
This easy banchan recipe works so well because it focuses on simple ingredients and balance.
- Salting the cucumbers first removes excess water so the salad stays crisp instead of watery.
- Garlic and sesame oil bring deep savory flavor.
- Gochugaru (Korean chili flakes) add a gentle heat without overwhelming the dish.
This gives you a bright, crunchy cucumber salad that pairs perfectly with almost any Korean meal!
Tips for the Best Korean Cucumber Salad
Use fresh cucumbers
- Firm cucumbers give the best crunchy texture.
Do not skip salting
- This removes water and helps the seasoning stick to the cucumbers.
Adjust the spice
- Add more gochugaru if you like a spicier cucumber salad.
Let it marinate
- Even 1-2 hours in the fridge makes the flavors much deeper.
