Korean Cucumber Salad is addicting! Cool crunchy cucumber slices are tossed in a spicy slightly sweet dressing. Gochugaru chili flakes (Korean chili flakes) are what really make this dish, they have a sweet fruity smoky flavor with moderate heat, unique flavor, and are hard to substitute. Fortunately, they have become more popular and easier to find. We slice the cucumbers thick to hold more crunch and juice, cooling the spice of the chili flakes. It is quite satisfying to bite into! That said, feel free to cut in thin slices if that works best with what you are serving it with.
We love all the fresh cucumbers available at the farmer’s market right now! Here is some more inspiration for this delicious vegetable (or is it fruit?) 20+ Cool Cucumber Recipes.

Ingredients In Cucumber Salad

Ingredient Notes
- 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.
