This particular Korean Cucumber Salad recipe is incredibly adaptable. You can adjust the level of heat to suit your taste or swap in different types of vinegar.

Once you try it, you’ll understand why this dish is so beloved.

Why You’ll Love This Recipe

You will appreciate how this salad comes together with minimal effort. It requires no special equipment and uses pantry-friendly ingredients like soy sauce, sesame oil, and garlic. The result is a side dish that feels gourmet but is deceptively simple to prepare. This Korean Cucumber Salad is also naturally vegan and gluten-free if you use tamari, making it a great option for various dietary needs.

Its versatility is another major selling point. Serve it alongside our popular Korean Beef Bulgogi for a complete meal. It also pairs wonderfully with grilled fish, tofu, or simply a bowl of steamed rice. The bright, clean flavors cut through richer dishes, providing a refreshing contrast that cleanses the palate.

The Essential Ingredients

While the ingredient list is short, each component plays a crucial role. English or Persian cucumbers are ideal because they have fewer seeds and thinner skin, requiring no peeling. Gochugaru, or Korean red pepper flakes, provides the characteristic mild heat and vibrant color; it’s different from other chili flakes. For a deeper dive into this essential Korean ingredient, you can refer to this resource on Gochugaru.

The combination of rice vinegar, sugar, and soy sauce creates the foundational sweet-and-sour base. Toasted sesame oil and seeds add a nutty, aromatic finish that is unmistakable. Fresh garlic and green onions bring sharpness and freshness, rounding out the complex flavor profile of this classic Korean Cucumber Salad.

How to Make Korean Cucumber Salad

Prep Time: 10 minutes | Cook Time: 0 minutes | Total Time: 10 minutes | Servings: 4

Ingredients

  • 1 pound English or Persian cucumbers (about 2-3 medium)
  • 1 teaspoon fine sea salt
  • 2 cloves garlic, minced
  • 2 green onions, thinly sliced
  • 1 tablespoon soy sauce (or tamari)
  • 1 tablespoon rice vinegar
  • 1 teaspoon granulated sugar
  • 1 tablespoon gochugaru (Korean red pepper flakes)
  • 1 teaspoon toasted sesame oil
  • 1 teaspoon toasted sesame seeds

Instructions

  1. Wash the cucumbers. You can slice them thinly into rounds, halve them lengthwise and slice into half-moons, or for a traditional look, score them lengthwise with a fork before slicing.
  2. Place the sliced cucumbers in a medium mixing bowl and sprinkle with the teaspoon of salt. Toss well to coat and let them sit for 5-7 minutes. This step draws out excess water and helps the cucumbers stay crisp.
  3. While the cucumbers are resting, prepare the dressing. In a small bowl, whisk together the minced garlic, soy sauce, rice vinegar, sugar, gochugaru, and sesame oil until the sugar is dissolved.
  4. After the cucumbers have sat, drain any liquid that has pooled in the bottom of the bowl. You can gently squeeze them in a clean towel if you want them extra dry.
  5. Pour the prepared dressing over the drained cucumbers. Add the sliced green onions and sesame seeds.
  6. Toss everything together until the cucumbers are evenly coated in the vibrant red dressing. Taste and adjust seasoning if desired.
  7. Serve immediately for the crunchiest texture, or let it marinate in the refrigerator for 10-15 minutes for more infused flavor.

Tips

  • For the best texture, make and eat this Korean Cucumber Salad the same day. It can become watery if stored for too long.
  • If you can’t find gochugaru, you can substitute a mix of 1/2 teaspoon crushed red pepper flakes and 1/2 teaspoon sweet paprika for a similar color and mild heat.
  • Feel free to add a pinch of MSG (a dash of dashida seasoning) or a teaspoon of Korean plum extract (maesil cheong) for an extra layer of savory-sweet complexity.
