Korean Cucumber Salad Recipe Ingredeints
- Cucumber- English cucumbers, Japanese cucumbers, Armenian cucumbers, or Persian cucumbers- any thin-skinned variety with minimal seeds.
- Rice Vinegar– best for flavor but in a pinch substituting with apple cider vinegar, or champagne vinegar is fine.
- Green onions- or scallions add lovely flavor and color.
- Sesame oil– toasty deep flavor.
- Sesame seeds – for finishing the salad, and adding texture.
- Sugar– honey or maple syrup will work too.
- Gochugaru- dried Korean red pepper flakes, spicy but not super hot, start with less and add more to taste. This is a really unique flavor that is key is achieving the Korean taste. You could substitute with regular chili flakes or Aleppo chili flakes, or even cayenne pepper- but it will not give it that authentic Korean taste.

How to make it!
Step 1: In a colander, toss cucumbers with 1 teaspoon of salt and set over a plate for 30 minutes. (See notes for skipping this step).


Lightly rinse the cucumber slices. Use a towel to blot and dry removing excess moisture.


Step 2: In a large mixing bowl whisk together the soy sauce, vinegar, honey, sesame oil, scallions, and Gochogaru chili flakes.
Step 3: Add the salted, rinsed, blotted, cucumbers to the dressing in the bowl and mix.

Serving Suggestions and Storage
Serve the salad sprinkled with sesame seeds and fresh cilantro. Leftovers will keep 3-4 days in the refrigerator, but after day two the cucumbers will become less crisp.
What to Serve with it!
Korean cucumber salad is typically served as a summer banchan because of its cooling effects, along with Korean BBQ and rice.
