Step‑by‑Step Instructions for Japanese Cucumber Salad
Step 1: Prepare the Cucumbers
Begin by washing the cucumbers thoroughly under cool running water. You can choose to peel them if you prefer a milder flavor or texture. Once clean, slice the cucumbers thinly—about 1/8 inch—using a sharp knife, mandoline, or spiralizer. The aim is to achieve uniform slices for even marination, which will contribute to the refreshing taste of your Japanese Cucumber Salad.
Step 2: Salt the Cucumbers
In a medium bowl, place the cucumber slices and sprinkle them generously with salt. Gently toss the slices to ensure they are evenly coated. Let them sit for 10 to 15 minutes, allowing the salt to draw out excess moisture. You’ll notice the cucumbers will begin to soften slightly while exuding a glistening liquid, which is crucial for the salad’s texture and flavor.
Step 3: Drain the Cucumbers
After letting them sit, it’s time to drain the excess moisture from the cucumbers. You can do this by squeezing them gently in your hands or patting them dry with a clean kitchen towel or paper towels. This step ensures that your Japanese Cucumber Salad remains crisp and doesn’t become watery when adding the dressing.
Step 4: Mix the Dressing
In a separate bowl, combine rice wine vinegar, sugar, and soy sauce. Whisk the mixture until the sugar is fully dissolved, which should take about a minute. If you choose to use sesame oil for added depth, stir it in now. The dressing should be well-balanced, with a tangy and slightly sweet flavor that will beautifully complement the cucumbers in your salad.
Step 5: Combine and Toss
Add the drained cucumber slices into the bowl with the dressing, and use a spatula or tongs to gently toss everything together. Make sure every cucumber piece is evenly coated in the flavorful mixture. This step is essential for enhancing the overall taste and ensuring each bite of your Japanese Cucumber Salad is deliciously tangy.
Step 6: Garnish
If desired, sprinkle toasted sesame seeds over the salad for an extra nutty crunch. Additionally, you can add thinly sliced seaweed, such as wakame or nori, for an authentic Japanese touch. The garnishes not only enhance the presentation of the Japanese Cucumber Salad but also add a layer of flavor.
Step 7: Chill and Serve
For the best flavor experience, cover the bowl with plastic wrap and place it in the refrigerator for 15 to 20 minutes. This resting period allows the flavors to meld beautifully, making your salad even more refreshing. Once chilled, give it a light toss again and serve as a delightful side dish at your next meal!

Tips for the Best Japanese Cucumber Salad
-
Slice Evenly: The key to a great Japanese Cucumber Salad is uniform cucumber slices. This ensures that all pieces marinate well and maintain a consistent texture.
-
Don’t Rush the Salting: Allow cucumbers to sit with salt for 10-15 minutes to draw out excess moisture. This step is crucial for achieving that satisfying crunch and preventing a watery salad.
-
Use Fresh Ingredients: Opt for the freshest cucumbers available. Limp or overripe cucumbers can negatively affect both the texture and flavors of your salad.
-
Marinate for Flavor: After combining cucumbers with the dressing, keep the salad in the refrigerator for at least 20 minutes. This chilling time allows the flavors to meld seamlessly for a tastier dish.
-
Customize Wisely: Feel free to add sesame oil or seaweed for an authentic touch, but ensure these additions enhance the overall flavor without overpowering the refreshing essence of the Japanese Cucumber Salad.

Storage Tips for Japanese Cucumber Salad
Fridge: Store the salad in an airtight container for up to 2 days. Enjoy its refreshing crunch, but note that the cucumbers may lose some crispness over time.

Reheating: If you prefer your salad slightly warmed, allow it to sit at room temperature for a few minutes before serving. Avoid microwaving, as it may alter the texture and flavor.
Separation: If storing for later, keep the dressing separate until you’re ready to serve. This helps maintain the freshness of your Japanese Cucumber Salad.
Make Ahead Options

Japanese Cucumber Salad (Sunomono) Recipe FAQs
What type of cucumbers should I use for the salad?
Absolutely! Japanese or English cucumbers are your best bet as they have a crisp texture that holds up well in the salad. If those are unavailable, don’t hesitate to substitute Persian or Armenian cucumbers, which also provide a satisfying crunch. Just be sure they are fresh and firm to get that delightful bite!
How should I store leftover Japanese Cucumber Salad?
Definitely store your salad in an airtight container in the refrigerator for up to 2 days. While it remains tasty, be mindful that the cucumbers may lose some of their initial crunch. To keep it fresh longer, consider storing the dressing separately until you are ready to serve!
Can I freeze this Japanese Cucumber Salad?
I wouldn’t recommend it! Freezing this salad can lead to mushy cucumbers when thawed, which is not what you want for that refreshing bite. Enjoy it fresh right after making for the best flavor and texture!
What if my cucumbers are too soft or overripe for the salad?
Very! If you find that your cucumbers are overripe or too soft, they may not provide the crunch and freshness that’s essential to this salad. Instead, I recommend opting for fresher cucumbers. If they are only slightly soft, peel them and slice them into smaller pieces, but keep your eye out for any dark spots or blemishes—those are signs they’re past their prime.
Can I use sugar substitutes in the dressing for dietary needs?
Absolutely! You can easily swap regular sugar with a diabetic-friendly sugar substitute like stevia or erythritol. Just adjust the amount to taste, as these alternatives can be sweeter than regular sugar. Your Japanese Cucumber Salad will still maintain its delightful flavor while being suitable for various dietary considerations!
How can I enhance the flavor of my salad?
Very! If you’re looking to elevate the flavor profile, try adding a dash of sesame oil for a rich, nutty taste or include some thinly sliced seaweed (wakame or nori) for an authentic touch. Both options add depth without overpowering the fresh, crisp essence of the Japanese Cucumber Salad. Enjoy experimenting!
