A complete printable recipe and the measurements in both US customary and metric are available in the recipe card below.
Prepare the cucumber
Thinly slice the cucumbers and toss them gently with salt in a small bowl. Set the sliced cucumbers aside for 25 – 30 minutes. We recommend placing them in a colander over the sink to let any liquid drip down the drain.
Make the salad
Drain any excess moisture, and gently toss the cucumber slices in a large mixing bowl with gochugaru (Korean red pepper flakes or powder), chopped scallions (green onion), sugar, minced garlic, rice vinegar (or rice wine vinegar), toasted sesame seeds, and sesame oil, ensuring that the sliced cucumber is evenly coated. Serve and enjoy!


Ingredients
- 1 tsp Salt
- 2 Korean cucumbers any thin cucumber will work
- 1 tbsp Gochugaru Korean red chili flakes
- 1 Scallion sliced
- ½ tsp Sugar
- ½ tsp Garlic minced
- 1 tsp Rice wine vinegar
- 1 tsp Sesame seeds
- 1 tsp Sesame oil

Serve and enjoy.2 Korean cucumbers, 1 tbsp Gochugaru Korean red chili flakes, 1 Scallion, ½ tsp Sugar, ½ tsp Garlic, 1 tsp Rice wine vinegar, 1 tsp Sesame seeds, 1 tsp Sesame oil
Notes
- Gochugaru: These are spicy Korean chili flakes that can be found in Korean markets, some Asian markets, and online. It’s essential for this simple Korean cucumber salad, but you’ll also find Korean red chili flakes in other dishes like kimchi. If you can’t find Gochugaru try regular chili pepper flakes, chili powder, or chipotle powder instead.
- Cucumber: Korean cucumbers are long, thin, crunchy cucumbers that are great for pickling and making side dishes such as this Korean cucumber salad recipe. Other fresh cucumbers would work perfectly as well, like English cucumber, Persian cucumbers with their thin skin, Kirby cucumbers, or pickling cucumbers. Make sure they are thinly sliced so that the excess liquid is easier to drain.
- Vinegar: If you don’t have rice vinegar on hand, use white vinegar instead. Add half of the amount in the recipe with a splash of soy sauce for some umami.
- Sugar: You can use maple syrup or honey instead of sugar for another layer of flavor.
- Toast sesame seeds: We highly recommend toasting the sesame seeds before adding them to the Korean Spicy Cucumber Salad. It really brings out their nutty flavor and adds a slight crunch. All you have to do is pop the sesame seeds in a skillet over low-medium heat, and stir them with a wooden spoon until they turn golden brown. It takes about 2 minutes!

Ahhh it’s perfect with rice!
I love this cucumber salad and had never salted cucumber but love the flavor from doing that. I used Kirby cucumbers and the salad was delicious, totally love the crunchy toppings. I served this as a side with my stir fry.
