How to Make Spicy Korean Cucumber Salad
This Spicy Korean Cucumber Salad is a culinary dream come true: astonishingly simple to prepare, bursting with bold and addictive flavors, and incredibly satisfying with its crisp texture. In under 20 minutes, you’ll have a dish that’s both a refreshing palate cleanser and a flavor explosion, perfect for any occasion.
Step-by-Step Instructions
- Prepare the Cucumbers: Wash the cucumbers thoroughly. For an optimal texture that absorbs the dressing beautifully, slice the cucumbers in half lengthwise. Then, using a spoon, gently scoop out and discard the watery seeds from the center of each cucumber half.
- Slice the Cucumbers: Now, thinly slice the seeded cucumber halves into bite-sized pieces, about 1/4 inch thick. You can achieve this by slicing them lengthwise into thin planks and then crosswise into half-moons or wedges. Place the sliced cucumbers into a medium-sized mixing bowl.
- Salt the Cucumbers (Optional but Recommended for Texture): If you have a few extra minutes, sprinkle the sliced cucumbers with about 1/4 teaspoon of salt. Gently toss them to coat. Let them sit for about 10-15 minutes. This step helps to draw out excess moisture, resulting in a crisper salad that won’t become watery. After salting, drain any liquid that has accumulated at the bottom of the bowl.
- Make the Dressing: In a small bowl, whisk together the gochugaru (Korean chili flakes), soy sauce, rice vinegar, sesame oil, granulated sugar (or your preferred sweetener), minced garlic, and toasted sesame seeds. Taste the dressing and adjust the soy sauce, vinegar, or sugar as needed to achieve your preferred balance of salty, sour, and sweet. If you prefer a milder spice, start with a smaller amount of gochugaru and add more to your liking.
- Combine and Toss: Pour the prepared dressing over the salted (or un-salted) sliced cucumbers in the main mixing bowl.
- Marinate and Serve: Gently toss the cucumbers with the dressing until they are evenly coated. For the best flavor, let the salad marinate for at least 10-15 minutes at room temperature, allowing the flavors to meld. If you prefer a chilled salad, you can refrigerate it for up to 30 minutes before serving.
- Garnish and Enjoy: Just before serving, if using, sprinkle with thinly sliced red onion or chopped green onions for an extra layer of freshness and color. Serve immediately as a delightful side dish.
