Ingredients You’ll Need

- 2 tablespoons rice vinegar: Adds that signature tangy and slightly sweet flavor that brightens the dish.
- 1 tablespoon sugar: Balances acidity and enhances the overall flavor profile.
- 1 teaspoon soy sauce: Brings mild umami depth and a subtle saltiness.
- 1 teaspoon sesame oil: Infuses the salad with a toasty, nutty aroma that elevates every bite.
- 1 teaspoon sesame seeds: Adds a delightful crunch and visual appeal as a garnish.

How to Make Japanese Cucumber Salad Recipe
Step 1: Prepare the Cucumbers
Start by washing your Japanese cucumbers thoroughly to remove any dirt or residue. Slice them thinly, about 1/8 inch thick; using a mandoline slicer here ensures consistent, delicate slices that soak up the dressing evenly.
Step 2: Salt and Drain
Place the sliced cucumbers in a bowl and sprinkle them with 1 teaspoon of salt. Toss well so every slice is coated. Let this sit for 10 minutes to draw out excess water, which helps keep the salad from becoming soggy and intensifies the cucumber’s crispness.
Step 3: Rinse and Squeeze
After resting, rinse the salted cucumbers under cold water to wash away the extra salt. Drain them thoroughly and gently squeeze out any lingering water using your hands or a clean kitchen towel. This step is key to preventing watery dressing and maintaining that perfect crunch.
Step 4: Whisk the Dressing
In a small bowl, whisk together rice vinegar, sugar, soy sauce, sesame oil, and if you like a bit of heat, red pepper flakes. This quick mix combines sweet, savory, and nutty notes that make this Japanese Cucumber Salad Recipe uniquely addictive.
Step 5: Combine and Toss
Add the drained cucumber slices to the dressing bowl. Toss everything gently, making sure each cucumber slice is evenly coated but still intact—this helps keep the texture vibrant.
Step 6: Chill
Refrigerate the salad for at least 15 minutes; this resting time allows the flavors to meld beautifully and the salad to cool, enhancing its refreshing quality.
Step 7: Garnish and Serve
Before serving, sprinkle sesame seeds and chopped green onion over the salad for added texture, flavor, and a pop of color. These small touches bring the dish to life visually and taste-wise.

Garnishes
Simple garnishes like toasted sesame seeds and finely chopped green onions add that final crunchy bite and a burst of fresh color. You can also experiment with a sprinkle of toasted nori flakes or thinly sliced chili for an extra layer of flavor.
Side Dishes
This salad is an outstanding companion to grilled meats, especially teriyaki chicken or salmon, and pairs beautifully with rice bowls or even sushi. Its lightness and acidity help balance heavier dishes, making it a perfect side that refreshes the palate.
Creative Ways to Present
For a fun twist, try serving this Japanese Cucumber Salad in small glass jars or mini bowls for individual portions during gatherings. Another idea is layering it on top of chilled soba noodles or alongside avocado slices for a bright, textural contrast that will wow your guests.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store the salad in an airtight container in the refrigerator. It stays fresh and crunchy for up to 2 days, although it’s best enjoyed the same day for peak texture.
Freezing
This Japanese Cucumber Salad Recipe is not suitable for freezing since cucumbers have a high water content that can become mushy after thawing.
Reheating
There’s no need to reheat this salad. It’s designed to be enjoyed cold, so just serve it straight from the fridge for maximum refreshment.
FAQs
Can I use regular cucumbers instead of Japanese cucumbers?
Yes, you can, but Japanese cucumbers tend to be thinner and less bitter with fewer seeds, which makes the salad extra crisp and less watery. If using regular cucumbers, consider peeling and deseeding them for the best results.
Is the salad spicy if I add red pepper flakes?
The red pepper flakes add a gentle warmth without overwhelming the delicate flavors. It’s a subtle heat that balances the sweetness and acidity nicely, but you can always adjust or omit them based on your heat tolerance.
Can I make this Japanese Cucumber Salad Recipe vegan?
Absolutely! This recipe is naturally vegan as all ingredients are plant-based, making it a perfect fresh and healthy option for vegan diets.
How long does it take to make this salad?
This salad comes together quickly with about 15 minutes of prep and no cooking time. Including chilling time for best flavor, plan for around 30 minutes total from start to finish.
What can I substitute for rice vinegar?
If you don’t have rice vinegar, you can use white wine vinegar or apple cider vinegar in a pinch. Just use slightly less and add a pinch of sugar to keep the balance of flavors right.
