Ingredients You’ll Need

Cucumbers

• 2 English cucumbers, thinly sliced
  • You can also use 4–5 small Persian cucumbers.
  • Avoid thick-skinned waxed cucumbers, since they turn watery and soft.

Aromatics

• 2 cloves garlic, minced very finely
• 2 green onions, thinly sliced (white and green parts)

Seasoning sauce

• 1½ tablespoons Korean red pepper flakes (gochugaru)
  • Use coarse gochugaru for the best texture and color.
  • If you want a milder salad, start with 1 tablespoon and add more to taste.
• 1½ tablespoons soy sauce
  • Use low-sodium soy sauce if you watch salt.
• 1 tablespoon rice vinegar
  • Plain rice vinegar or seasoned both work; reduce sugar slightly if you use seasoned.
• 1 teaspoon sugar or honey
  • Sugar gives a clean flavor; honey adds a light floral note.
• 1 tablespoon toasted sesame oil
• 1 tablespoon toasted sesame seeds
• ½ teaspoon kosher salt, plus more to taste

Optional add-ins

• ½ small carrot, cut into thin matchsticks, for extra crunch and color
• ½ teaspoon fish sauce, for deeper savory flavor
• Pinch of black pepper or white pepper

Pantry shortcuts & notes

• Use pre-minced garlic from a jar if you feel tired, but chop it a bit smaller so it blends in.
• If you cannot find gochugaru, mix 2 parts sweet paprika with 1 part mild chili flakes as a backup, though the flavor will taste slightly different.
• Tamari works well instead of soy sauce if you need a gluten free option.

Equipment

• Cutting board and sharp knife
• Medium mixing bowl
• Small bowl for the seasoning sauce
• Colander or strainer
• Measuring spoons
• Chopsticks or tongs for tossing

Tips & Tricks

• Slice cucumbers evenly so they season at the same rate and keep a consistent crunch.
• Salt the cucumbers lightly first, then drain off extra water so the salad does not turn watery.
• Use cold cucumbers from the fridge; they stay crisper and taste more refreshing.
• Stir the seasoning sauce separately, then toss with cucumbers so the flavors coat every slice.
• Taste and adjust at the end: add more vinegar for tang, more soy for salt, or more sugar for balance.
• Chill the salad 10 to 15 minutes before serving if you have time, so the flavors settle in.
• Add gochugaru gradually if you feel unsure about heat, since it builds as the salad sits.
• Toast sesame seeds in a dry pan for 1 to 2 minutes until fragrant to boost nutty flavor.

How to Make Easy Korean Cucumber Salad Recipe

Step 1: Prep and salt the cucumbers

Wash the cucumbers and pat them dry. Slice them into thin rounds, about ⅛ to ¼ inch thick, and place them in a mixing bowl. Sprinkle with ½ teaspoon kosher salt, toss well, and let them sit 10 minutes while you mix the seasoning.

After 10 minutes, drain off the released liquid and gently squeeze the cucumbers with your hands to remove excess water. Do not crush them; you just want to press out some moisture so they stay crunchy and soak up flavor.

Step 2: Mix the seasoning sauce

In a small bowl, combine gochugaru, soy sauce, rice vinegar, sugar or honey, sesame oil, and minced garlic. Stir until the sugar dissolves and the mixture looks smooth and glossy. Add the sliced green onions, sesame seeds, and any optional fish sauce or pepper.

Taste the sauce with one cucumber slice and adjust the seasoning. Add a pinch more sugar if it tastes too sharp, or a splash more soy sauce if you want extra savory depth.

Step 3: Toss everything together

Pour the seasoning sauce over the salted cucumbers. Use chopsticks, tongs, or clean hands to toss until every slice looks evenly coated with the red seasoning. Add the carrot matchsticks if you use them and toss again.

Taste one more time and tweak the flavors to your liking. If the salad tastes too salty, add a few more plain cucumber slices. If it tastes too mild, sprinkle in a bit more gochugaru or a few drops of vinegar.

Step 4: Rest and serve

Let the Korean cucumber salad sit for 5 to 10 minutes at room temperature so the flavors meld. Stir once more before serving and sprinkle a few extra sesame seeds on top for a nice finish. Serve it slightly chilled or cool, not ice cold, so the flavors stay bright.

You can serve this Easy Korean Cucumber Salad Recipe right away, or chill it up to an hour before serving. The cucumbers soften a bit as they sit, but they keep a pleasant crunch.

What to Serve with Easy Korean Cucumber Salad Recipe

This Easy Korean Cucumber Salad Recipe pairs beautifully with steamed white rice, brown rice, or simple fried rice. It also tastes great next to grilled chicken, baked salmon, tofu, or pan-seared shrimp. I like to add it to bibimbap bowls, noodle bowls, or simple lettuce wraps with leftover protein. You can even serve it as a crunchy side with sandwiches or as a snack with some roasted seaweed and fruit.

Storage Options

• Store leftover Korean cucumber salad in an airtight container in the fridge for up to 2 days.
• Stir before serving again, since the dressing can settle at the bottom of the container.
• Do not freeze this salad, since cucumbers turn mushy and lose their crunch after freezing.
• Serve leftovers straight from the fridge or let them sit at room temperature for 5 to 10 minutes to take the chill off before eating.
