How to make Korean Cucumber Salad with step-by-step instructions
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!
Recipe notes and expert tips
- 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. If you can’t find them at the grocery store, then other fresh cucumbers would work perfectly as well, like English cucumbers, 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.
- 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!
- Sugar: You can use maple syrup or honey instead of sugar for an extra layer of flavor.
How to store leftover Korean cucumber salad
Store any leftover spicy cucumber salad in an airtight container in the fridge for up to 3 days. Drain off any excess liquid before consuming. To freshen it up, toss in a teaspoon of sesame oil and sprinkle some fresh green onions over it.
