What is Korean Cucumber Salad?
Korean spicy cucumber salad, also known as Oi Muchim is a popular side dish that is sometimes used as a quick kimchi substitute. Oi translates as “cucumber”, and muchim means “seasoned”. There are so many different variations of this salad, that you can definitely make it your own (see the variations section for ideas).
Ingredients and Substitutions
- long English cucumber: skin on, sliced into 2-3mm thick slices.
- red bell pepper: completely optional, but we love it for the flavour and colour in this Asian Cucumber salad.
- soy sauce: we used dark soy sauce. If you’re looking for a gluten-free option, look for Tamari.
- rice vinegar: can be substituted with white wine vinegar.
- caster sugar: or white granulated sugar, but it will take longer to dissolve.
- chilli powder: ideally, you want Korean red chilli powder (Gochugaru) for this recipe, but any chilli powder will work.
- sesame seeds: could be substituted for nigella seeds.
- spring onions: thinly sliced, alternatively use finely chopped red onion.

Method
Slice the cucumber into thin 2-3mm thick rounds. Chop the spring onion and red pepper (if using) finely.
Add cucumber, spring onion and bell pepper to a large bowl.

In a separate small bowl, mix together rice vinegar, soy sauce, chilli powder, sugar and sesame seeds. Stir until the sugar has dissolved.
Pour the vinaigrette over the vegetables and toss gently to coat. Serve immediately.
Variations
Why not try this recipe by changing things up a bit:
- Add a teaspoon of sesame oil to the dressing.
- Replace spring onion with finely chopped red onion.
- Add honey instead of sugar.
- Skip the chilli powder and use Gochujang paste instead.
Recipe FAQs
Any cucumber with soft enough skin that doesn’t need peeling will work just fine! English, Persian or short garden-grown varieties will work in this recipe!
It can be if the soy sauce you choose is gluten-free. Look for Tamari (a type of soy sauce) – it is usually gluten-free.
