Asian Cucumber Salad is a cool, crunchy side dish tossed with rice vinegar, soy sauce, toasted sesame oil, garlic, and a touch of chili. The cucumbers stay crisp while absorbing a balanced dressing that tastes tangy, savory, lightly sweet, and nutty.
Salting the sliced cucumbers for 20 minutes draws out excess water before the dressing is added. This simple step keeps the salad from becoming diluted and gives it a firmer, more refreshing texture.
Why This Recipe Works
- Salting the cucumbers removes excess moisture, helping the dressing cling instead of collecting as a watery pool.
- Persian cucumbers have thin skins and small seeds, so they stay crisp without peeling or seeding.
- Rice vinegar supplies clean acidity without overpowering the fresh cucumber flavor.
- Soy sauce, sesame oil, and garlic create a savory dressing with depth despite the short ingredient list.
- Adding sesame seeds and green onions after draining the cucumbers preserves their texture and fresh flavor.

- 1/4 cup (60 ml) unseasoned rice vinegar
- 2 tablespoons (30 ml) reduced-sodium soy sauce
- 1 tablespoon (15 ml) toasted sesame oil
- 1 tablespoon (12 g) granulated sugar
- 2 garlic cloves, finely grated or minced
- 1 teaspoon (5 ml) chili crisp or chili oil

For Finishing
- 3 green onions, thinly sliced
- 1 tablespoon (9 g) toasted sesame seeds

Ingredient Notes and Substitutions
- Persian cucumbers: Persian cucumbers have tender skins, few seeds, and a crisp texture. English cucumber can be substituted in the same weight; slice it into thin half-moons if it is especially large. Standard slicing cucumbers can also be used, but peel thick skins and remove large seeds to prevent a watery salad.
- Rice vinegar: Unseasoned rice vinegar provides mild, clean acidity. Apple cider vinegar can replace it in the same quantity, but the salad will have a sharper, fruitier flavor. Avoid seasoned rice vinegar unless the sugar and soy sauce are reduced, since seasoned vinegar already contains added sugar and salt.
- Soy sauce: Soy sauce adds salt and savory flavor to the dressing. Tamari can replace it in the same quantity for a wheat-free version, provided the other packaged ingredients also meet that requirement. Coconut aminos may be used, but the dressing will taste sweeter and less salty.
- Toasted sesame oil: Toasted sesame oil supplies concentrated nutty flavor. Use it as a seasoning rather than the main oil. There is no close substitute, though a small amount of neutral oil can be used if necessary; the salad will lose much of its characteristic sesame flavor.
- Chili crisp: Chili crisp adds heat, oil, and savory flavor. Plain chili oil can replace it in the same quantity for a smoother dressing. For a mild salad, omit it and the optional red pepper flakes.
Step-by-Step Instructions
Step 1: Slice the cucumbers
Cut the Persian cucumbers into rounds approximately 1/4 inch (6 mm) thick. Keep the slices as even as possible so they soften and absorb the dressing at the same rate.
Step 2: Salt the cucumbers
Place the sliced cucumbers in a large colander set over a bowl or sink. Sprinkle with the salt and toss thoroughly. Let them stand for 20 minutes. Moisture should begin collecting beneath the colander.
Step 3: Make the dressing
While the cucumbers drain, whisk together the rice vinegar, soy sauce, toasted sesame oil, sugar, garlic, chili crisp, and optional red pepper flakes in a small bowl. Continue whisking until most of the sugar dissolves.
Step 4: Dry the cucumbers
Shake the colander well to remove released liquid. Spread the cucumbers on a clean kitchen towel or several layers of paper towels and blot gently. They should feel cool and slightly flexible but not wet.
Step 5: Dress the salad
Transfer the dried cucumbers to a large mixing bowl. Pour the dressing over them and toss until every slice looks lightly coated.
Step 6: Add the finishing ingredients
Add the sliced green onions, toasted sesame seeds, and cilantro, if using. Toss gently so the onions and sesame seeds are distributed without breaking the cucumber slices.
Step 7: Rest briefly
Let the salad stand for 5 minutes before serving. This gives the cucumbers time to absorb some of the dressing while remaining crisp.
Step 8: Taste and serve
Toss the salad once more and taste it. If it seems too sharp, add a small pinch of sugar. If it needs more acidity, add a teaspoon of rice vinegar. Serve chilled or at cool room temperature.
Storage, Freezing, and Make-Ahead Instructions
- Store Asian Cucumber Salad in an airtight container in the refrigerator for up to 2 days. The cucumbers will gradually soften and release more liquid, so stir the salad before serving and drain off excess dressing if necessary.
- For make-ahead preparation, slice and salt the cucumbers up to 4 hours in advance. Dry them well and refrigerate them separately from the dressing. Combine the cucumbers, dressing, green onions, sesame seeds, and optional cilantro shortly before serving.
- Freezing is not recommended because thawed cucumbers become soft and watery.
FAQ
Can I make Asian Cucumber Salad ahead of time?
Yes. For the best crunch, prepare the cucumbers and dressing separately, then combine them up to 2 hours before serving.
Why is my cucumber salad watery?
The cucumbers may not have been salted long enough or dried thoroughly after draining. Salt them for the full 20 minutes and blot away surface moisture before adding the dressing.
Can I use regular cucumbers?
Yes. Peel any thick or waxy skin, cut the cucumber in half lengthwise, and scrape out large seeds before slicing. Regular cucumbers tend to release more water than Persian cucumbers.
How can I make the salad less spicy?
Omit the chili crisp and red pepper flakes. The salad will still have plenty of flavor from the garlic, soy sauce, rice vinegar, and sesame oil.
Can I add other vegetables?
Yes. Thinly sliced radishes or shredded carrots work well. Keep additions to about 1 cup total so the dressing still coats the salad evenly.
