This Asian cucumber salad has become my go-to refresher during hot summer months, offering the perfect balance of crunch, tanginess, and subtle heat that transforms ordinary cucumbers into something extraordinary.
I first made this salad for an impromptu backyard gathering and it disappeared within minutes. Now it's requested at every family barbecue and has become my signature contribution to potlucks.
Ingredients
- Cucumber: cucumber varieties like Persian, Japanese, or English work best as they have fewer seeds and thinner skins
- Salt: drawing out excess moisture ensures your salad stays crisp rather than watery
- Garlic: fresh minced cloves provide essential aromatic backbone to the dressing
- Apple cider vinegar: adds brightness with a subtle fruity note that balances the seasonings
- Sugar: don't skip this as it creates the perfect sweet-savory balance that makes this salad addictive
- Korean chili powder: authentic gochugaru offers vibrant color and moderate heat without overwhelming
- Chili oil: provides richness and a lingering warm sensation on the palate
- Sesame oil: just a small amount adds incredible nutty depth that defines Asian cuisine
- Sesame seeds: toasted seeds finish the dish with pleasant crunch and visual appeal
Step-by-Step Instructions
- Prepare the Cucumbers:
- Slice cucumbers into thin rounds or half-moons about ¼-inch thick. Consistent sizing ensures even flavor absorption. Toss with salt and refrigerate for exactly 15 minutes. This critical salting step draws out excess moisture, concentrates flavor, and creates the perfect crisp texture.
- Create the Dressing:
- Mix garlic, vinegar, sugar, chili powder, chili oil, and sesame oil in a small bowl. Stir until sugar fully dissolves, about 30 seconds. This careful blending ensures each cucumber piece will be coated in a perfectly balanced dressing without any gritty sugar crystals.
- Combine and Serve:
- Drain cucumbers thoroughly, patting dry with paper towels if needed. Toss with the dressing until every piece is evenly coated. Sprinkle with sesame seeds just before serving to maintain their texture. The dressing will continue to infuse the cucumbers with flavor as they sit.

The first time I served this salad to my mother-in-law, who grew up in South Korea, she asked for my recipe. That moment of cultural connection through food remains one of my proudest cooking achievements.
Texture Variations
Many Asian cucumber salads feature a smashed cucumber technique rather than neat slices. Try placing cucumber spears on a cutting board and gently crushing with the flat side of a knife before cutting into bite-sized pieces. These irregular surfaces create pockets that catch more dressing and deliver intensified flavor with each bite.
Heat Level Customization
The recipe as written delivers a pleasant mild to medium heat that most people enjoy. For a more fiery version, double the Korean chili powder and add a teaspoon of gochujang paste. To make it kid-friendly, reduce the chili powder to ¼ teaspoon and omit the chili oil altogether, replacing it with a touch more sesame oil.
Serving Suggestions
This cucumber salad shines when paired with rich, savory main dishes. Serve alongside grilled meats, particularly Korean BBQ, or with salmon teriyaki for a refreshing counterpoint. For a complete meal, offer it with steamed rice and your protein of choice. The cooling crispness of the cucumbers particularly complements spicy dishes, creating the perfect balance.
