Korean Cucumber Salad (Oi Muchim)
A crisp, spicy-tangy Korean cucumber salad tossed with gochugaru, garlic, and sesame oil.
About This Recipe
Oi muchim is a quick banchan (side dish) found on nearly every Korean table, thinly sliced cucumbers tossed with a punchy mix of gochugaru, garlic, vinegar, and sesame oil. It comes together in minutes and adds a cooling crunch alongside richer, heavier main dishes. Salting the cucumbers briefly before dressing draws out excess water, which keeps the salad crisp rather than watery and diluting the dressing — a small step that makes a real difference in the final texture.

Pro Tips
- →
Salt the cucumbers for at least 10 minutes and drain well — this keeps the salad crisp rather than watery.
- →
Slice the cucumbers thinly and evenly, ideally with a mandoline, for the best texture.
- →
Serve this salad the same day it's made; it loses its crunch quickly once dressed and refrigerated.
Variations
- •
Add thinly sliced onion for extra crunch and sharpness.
- •
Include a splash of fish sauce for extra umami depth.
- •
Adjust the gochugaru amount to taste for a milder or spicier salad.
Storage
Best eaten within a few hours of making; refrigerated leftovers keep 1 day but the cucumbers soften and release more liquid.
History & Origin
Oi muchim is one of the most common banchan across Korean households, part of the broader Korean meal tradition of serving multiple small seasoned side dishes alongside rice and a main course.
Frequently Asked Questions
Why is my salad watery?
The cucumbers likely weren't salted and drained long enough before dressing; salt them for a full 10 minutes and drain off the liquid before tossing with the dressing.
Can I make this ahead of time?
It's best made fresh close to serving, since the cucumbers continue to release water and lose their crispness the longer they sit dressed.
What can I substitute for gochugaru?
A mix of paprika and a small amount of cayenne can approximate the color and mild heat, though the flavor won't be quite as complex as real gochugaru.
