Ingredients
For the Salad:
- 4 English cucumbers (or 6 Persian cucumbers)
- 1 teaspoon salt (for drawing out moisture)
For the Dressing:
- 2 tablespoons gochugaru (Korean red pepper flakes)
- 2 tablespoons rice vinegar
- 1 tablespoon soy sauce (or tamari for gluten-free)
- 1 tablespoon toasted sesame oil
- 1 tablespoon sugar (or honey)
- 2 cloves garlic, minced
- 1 teaspoon sesame seeds (plus more for garnish)
- 2 green onions, thinly sliced
- 1 red chili, thinly sliced (optional, for heat)
Tips for the Best Korean Cucumber Salad
- Use English or Persian cucumbers. They have thin skins and fewer seeds, making them ideal for salads. Regular cucumbers work too, but peel and seed them first.
- Don’t skip the salting step. Drawing out excess moisture prevents the salad from becoming watery and keeps the cucumbers crisp.
- Adjust the spice level. Gochugaru can vary in heat. Start with 1½ tablespoons and add more to taste. For a milder version, use less gochugaru or omit the red chili.
- Use toasted sesame oil. Toasted sesame oil has a richer, nuttier flavor than regular sesame oil. It’s essential for authentic flavor.
- Make it ahead. This salad tastes even better after 30 minutes in the fridge as the flavors meld together.
- Serve with Korean BBQ. This salad is the perfect refreshing side dish for grilled meats, bulgogi, or Korean fried chicken.
- Add a kick. For extra heat, add a pinch of gochugaru flakes or a drizzle of chili oil.
Easy Variations
Make it Not Spicy: Omit the gochugaru and red chili. Add extra sesame oil and rice vinegar for a mild, refreshing version.
Make it with Soy Sauce: Add 1 tablespoon of soy sauce to the dressing for a deeper, more savory flavor.
Make it with Sesame Seeds: Toasted sesame seeds add nutty crunch. Toast them in a dry skillet for 1 to 2 minutes before adding.
Add Crunch: Toss in sliced red onion, shredded carrots, or daikon radish for extra texture.
Make it a Meal: Add shredded chicken, tofu, or edamame to turn this into a light lunch.
Make it with Cucumber Noodles: Use a spiralizer to make cucumber noodles for a fun twist.
Storage
- Refrigerate: Store leftover cucumber salad in an airtight container in the fridge for up to 3 days. The cucumbers may release some water, so drain before serving.
- Make ahead: This salad is best served within a few hours of making, but it can be made up to 1 day ahead. The flavors will meld and deepen.
