I make this Korean cucumber salad all summer long. It’s crisp, bright, and the kind of acidic, spicy little salad that wakes up an entire meal. Thinly sliced Korean or Persian cucumbers get salted to draw out moisture, then tossed with rice vinegar, soy, sesame, and gochugaru for a lively, crunchy side that’s ready in minutes. If you like quick Korean-inspired sides, you might also enjoy this Korean ground beef bowl recipe for an easy weeknight pairing.
What makes this recipe special
This salad is special because it’s fast and wildly refreshing. You get crunchy texture, tang from rice vinegar, umami from soy, and a warm, fruity heat from gochugaru or crushed chili flakes. It’s budget-friendly and needs no cooking. Make it for a summer barbecue, a simple weeknight dinner, or to balance rich mains with a cool, acidic side.

Step-by-step overview
Before you start: expect a very short hands-on time and one small resting period to pull moisture from the cucumbers. First, thinly slice and salt the cucumbers to draw out excess water. While they sit, whisk the dressing of vinegar, soy, sugar, sesame oil, and chili. Squeeze the cucumbers, fold in dressing, then finish with green onion, garlic if using, and sesame seeds. Chill for a quick 10 minutes or up to a few hours to let flavors meld.
What you’ll need
- 2 large cucumbers (Korean or Persian preferred; English cucumbers can work if peeled and seeded)
- 1 teaspoon salt
- 2 tablespoons rice vinegar
- 1 tablespoon soy sauce
- 1 tablespoon chili flakes or gochugaru (adjust for heat)
- 1 teaspoon sugar (or honey/agave)
- 1 tablespoon sesame oil
- 1 tablespoon sesame seeds (toasted for more flavor)
- 2 green onions, finely chopped
- 1 clove garlic, minced (optional)
Notes on swaps: use tamari for gluten-free, white vinegar only if rice vinegar is unavailable but reduce amount to avoid harshness, and substitute 1 teaspoon honey or agave for sugar if you prefer.
Step-by-step instructions
- Rinse cucumbers and slice thinly. A mandoline or very sharp knife helps.
- Toss the cucumber slices with 1 teaspoon salt in a bowl. Set aside for 8 to 10 minutes to draw out moisture.
- In a separate small bowl, whisk together rice vinegar, soy sauce, sugar, sesame oil, and chili flakes until sugar dissolves. Taste and adjust heat or acidity.
- Squeeze the cucumbers firmly in a clean towel or between your hands to remove excess liquid. Transfer them to a serving bowl.
- Add the dressing, then fold in minced garlic (if using) and chopped green onions. Toss gently until evenly coated.
- Sprinkle with sesame seeds and chill in the fridge for at least 10 minutes before serving so flavors settle. Serve cold.
Best ways to enjoy it
This salad is a natural foil for richer mains and fried foods because it cuts grease and refreshes the palate. Serve it alongside grilled chicken, pan-seared fish, or steamed rice bowls. For a complete weeknight plate, pair it with a hearty main; for example, try it with this Korean ground beef bowl to make a quick, balanced dinner. For plating, mound the salad in a shallow bowl and sprinkle extra sesame seeds and a few flakes of gochugaru on top for color.
Storage and reheating tips
Store leftovers in an airtight container in the refrigerator. Because cucumbers release water, the salad is best eaten within 24 to 48 hours; after that it becomes softer and more watery. Do not freeze this salad—freezing ruins the texture. If the salad gets watery, drain some liquid and refresh the dressing with a splash more rice vinegar and a pinch of sugar before serving.
Pro chef tips
- Slice as thinly as possible for the best crunch. A mandoline set to 1.5 to 2 mm is ideal.
- Salt time is crucial. Letting cucumbers sit 8 to 10 minutes removes excess water so the dressing stays bright and not diluted.
- Toast the sesame seeds in a dry pan until fragrant for a nuttier finish.
- If you prefer less heat, start with 1 teaspoon gochugaru and build up. If you like a smoky finish, lightly toast chili flakes in sesame oil before mixing them into the dressing.
- Keep garlic optional. Fresh garlic adds punch but can dominate if you make the salad ahead; add garlic right before serving when prepping in advance.
Flavor swaps
- Crunch and citrus: add thinly sliced radish or a bit of julienned carrot for color and texture.
- Creamy twist: fold in 2 tablespoons plain yogurt or a splash of tahini for a milder, creamier salad.
- Herb lift: stir in chopped cilantro or mint for a fresh finish.
- Vegan umami: use coconut aminos in place of soy for a different savory note.
- Extra crunch: top with crushed roasted peanuts or toasted pumpkin seeds for a crunchy finish.
Your questions answered
How long does this salad take to make?
Active prep is about 10 minutes. Allow 8 to 10 minutes for the cucumbers to sweat and at least 10 minutes of chilling after dressing, so plan roughly 30 minutes total from start to table.
Can I make this ahead of time?
You can make it a few hours ahead, but for best texture eat within 24 hours. If making more than 2 hours ahead, wait to add garlic and sesame seeds until just before serving to preserve flavor and crunch.
What can I use instead of gochugaru?
Use mild chili flakes for heat, or reduce quantity for less spice. Gochugaru has a fruity, slightly smoky flavor that is unique, so start small if you swap.
Will freezing ruin the salad?
Yes. Freezing breaks down cucumber cell walls and makes the salad mushy. Refrigerate and eat fresh instead.
Are there safe handling tips for cucumber salads?
Always use clean utensils and bowls. If you make the salad with garlic, keep it chilled and eat within 24 hours for best safety and quality. Discard if it smells off or the texture becomes slimy.
