For Garnishing

How to Make Japanese Cucumber Salad
-
Prepare the Cucumbers: Wash and thinly slice the cucumbers using a knife or mandoline. Place them in a bowl, sprinkle with salt, and massage gently to release moisture. Let them sit for about 10 minutes, then squeeze and drain.
-
Make the Dressing: In a separate bowl, whisk together the rice vinegar, sugar, soy sauce, mirin, and sesame oil until the sugar dissolves. This will create a smooth and flavorful dressing.
-
Combine: Add the drained cucumbers to the dressing, tossing gently to ensure an even coating. If you’re using wakame seaweed, fold it in carefully at this stage.
-
Chill & Serve: Refrigerate the salad for 5–10 minutes to enhance flavor. Before serving, garnish with sesame seeds and a sprinkle of red chili flakes for an added kick.
Optional: Drizzle with a bit of chili oil for an extra layer of heat!

Make Ahead Options
These Japanese cucumber salad (Sunomono) options are a lifesaver for busy home cooks! You can prepare the cucumbers and dressing separately up to 24 hours in advance to save time on hectic weeknights. Simply slice the cucumbers and salt them to draw out moisture, allowing them to rest for about 10 minutes before draining. For the dressing, whisk together rice vinegar, sugar, soy sauce, mirin, and sesame oil until sugar is dissolved and store it in the refrigerator. Just before serving, combine the cucumbers with the dressing, chill for 5-10 minutes, and garnish with sesame seeds and chili flakes to maintain that delightful crunch and vibrant flavor. Enjoy restaurant-quality results with minimal effort!
How to Store and Freeze Japanese Cucumber Salad
Fridge: Store any leftover Japanese cucumber salad in an airtight container for up to 24 hours. This helps maintain its crispness and flavor, but it’s best enjoyed fresh.
Freezer: Freezing is not recommended as it will compromise the texture of the cucumbers, making them soggy once thawed.
Reheating: If you happen to have any salad left (which is rare!), simply let it come to room temperature or chill again slightly before serving. Avoid reheating in a microwave or stoving, as that will ruin the freshness!
Serving Tip: Serve chilled for maximum refreshment and enjoyment, particularly on warm days.

Japanese Cucumber Salad Recipe FAQs
What cucumbers should I use for the best results?
Absolutely! For optimal crunch and hydration, I recommend using Japanese cucumbers or Persian cucumbers. They are thinner-skinned and provide a delightful snap. If those aren’t accessible, regular cucumbers can be a substitute, though the texture won’t be quite as crisp.
How should I store leftover Japanese cucumber salad?
You can store any leftovers in an airtight container in the refrigerator for up to 24 hours. However, I suggest consuming it fresh for the best flavor and crunch. After that timeframe, the cucumbers begin to release moisture, resulting in a less enjoyable salad.
Can I freeze Japanese cucumber salad?
I advise against freezing this salad. Freezing will alter the texture of the cucumbers, making them mushy once thawed. Sunomono is best enjoyed fresh, so try to make just enough for your meal!
What if I find my salad too salty or watery after draining?
If you notice your salad is too salty, you can balance it out by adding more fresh cucumbers or increasing the dressing quantity. To remedy a watery salad, ensure you properly salt and drain the cucumbers—let them sit for 10 minutes, then gently squeeze out the moisture before mixing with the dressing.
Are there any dietary considerations for Japanese cucumber salad?
Yes, Japanese cucumber salad is naturally gluten-free—just opt for gluten-free soy sauce, like tamari. If you have allergies, be cautious with the sesame oil and sesame seeds. For vegan options, this recipe is already vegan-friendly, ensuring everyone can enjoy its refreshing taste!
How can I customize the flavors?
The beauty of Sunomono lies in its versatility! You can add a pinch of red chili flakes for a spicy kick, or some rehydrated wakame seaweed for a traditional touch. For a fresh taste, I often incorporate herbs like cilantro or mint, which truly elevate the flavor profile.
