Why You’ll Love Japanese Cucumber Salad
This Japanese Cucumber Salad is the epitome of simplicity and freshness. It’s not only quick and easy but also incredibly healthy.

Ingredients for Japanese Cucumber Salad
• Japanese Cucumbers: The primary ingredient, these cucumbers are thin-skinned and have a mild flavor, which is ideal for the salad. If Japanese cucumbers aren’t available, Persian or English cucumbers can be used as a substitute.
• Soy Sauce: The soy sauce adds a savory depth of flavor to the dressing. Tamari can be used as a gluten-free alternative.
• Rice Vinegar: This ingredient provides the tanginess that balances the sweetness of the sugar, adding a refreshing zing to the salad.
• Sugar: A small amount of sugar is used to counteract the acidity of the vinegar, giving the salad a subtle sweetness. Honey or a sugar-free substitute can be used as alternatives.
• Toasted Sesame Oil (optional): Adds a slightly nutty flavor, enhancing the overall taste of the salad.
Alternative Ingredient Suggestions
If you’re looking for alternative options, you can try the following:
• For a gluten-free option, use tamari in place of soy sauce.
• To make it Paleo, swap the soy sauce and sugar with coconut aminos, which will add a naturally sweet flavor without the need for additional sweeteners.
• If you’re avoiding sugar, consider using stevia or monk fruit as a sugar substitute for a healthier twist.
Step-by-Step Instructions for Making Japanese Cucumber Salad
- Start by slicing the cucumbers as thin as possible, between ¼ to ⅛ inch thick. The thinner the slices, the better the texture.
- Sprinkle ¼ teaspoon of salt over the cucumbers and let them sit for about 10 minutes. This will help draw out excess moisture.
- After 10 minutes, rinse the cucumbers with cold water and drain them well. Wrap the cucumbers in a clean dish towel or paper towel and gently squeeze out the moisture.
- In a large bowl, combine the remaining salt, soy sauce, rice vinegar, sugar, and sesame oil. Mix until the sugar dissolves and the ingredients are well combined.
- Add the cucumbers to the bowl and toss to coat evenly with the dressing. Let the salad chill for about 15 minutes before serving to allow the cucumbers to absorb the flavors.

Tips & Tricks for Perfect Japanese Cucumber Salad
• Be sure to squeeze out as much moisture as possible from the cucumbers. This helps prevent the salad from becoming watery and ensures the cucumbers stay crisp.
• If you want the flavors to meld even more, prepare the salad ahead of time and let it chill in the refrigerator overnight.
• Adjust the sweetness and saltiness to your taste. If you prefer a less salty salad, reduce the amount of soy sauce.
• For extra crunch, you can sprinkle sesame seeds on top before serving.
Pairing Ideas and Variations
This Japanese Cucumber Salad pairs perfectly with a variety of dishes, including grilled meats, fish, and tofu. It’s a great side dish for a light meal or as part of a larger spread for a gathering. Here are a few pairing suggestions:
• Serve it with grilled salmon or tuna for a light and healthy dinner.

• For a vegan option, serve it alongside a tofu and broccoli stir-fry.
If you want to spice things up, add a small amount of chili flakes or sliced chili peppers to the dressing for a kick. Alternatively, make it a more substantial dish by adding cooked shrimp or sliced avocado.
Making It Ahead and Storing Leftovers
This salad is incredibly easy to prepare in advance. Once made, it can be stored in an airtight container in the refrigerator for up to 5 days. Over time, the cucumbers will lose some of their crispness, but the flavors will continue to develop and enhance.
