Side Dishes
This Japanese cucumber salad with mirin delivers the perfect balance of refreshing crunch and sweet-tart flavors that elevate any meal.
The secret lies in the mirin, which transforms simple cucumbers into a vibrant dish with layers of umami and brightness that complement grilled fish, sushi, or even a simple bowl of rice.
I developed this recipe after discovering how mirin's natural sweetness and acidity create harmony with the crisp cucumber and delicate sesame notes.
The preparation is straightforward yet precise: thinly slicing the cucumbers creates the signature crisp texture, while a quick soak removes excess moisture for an ideal bite.
The dressing combines mirin, rice vinegar, and a touch of sugar to create a light, glossy coating that enhances the cucumbers' natural freshness without overpowering them. Sesame seeds and chili flakes add contrasting textures and subtle heat, making every bite both satisfying and balanced.
What makes this salad truly special is its versatility—serve it as a refreshing side to sushi or grilled dishes, or enjoy it as a light, satisfying meal on its own. The dressing clings beautifully to the cucumber slices, creating a dish that's as visually appealing as it is delicious.
With minimal ingredients and just 15 minutes of active prep time, this recipe proves that simple ingredients can deliver restaurant-quality results.
The key to success is freshness—using crisp cucumbers and freshly ground sesame seeds ensures the best texture and flavor. For an extra touch of elegance, arrange the salad on a chilled platter before serving, allowing the colors to pop against the white plate.
This dish is perfect for summer gatherings, light lunches, or as a palate cleanser between rich courses. Let's get started!
Ingredients for japanese cucumber salad recipe mirin
Bright, crisp cucumbers meet sweet-tart mirin magic—just 11 ingredients for a dish that feels restaurant-fresh.
| Ingredient | Amount | Notes |
|---|---|---|
| Japanese Cucumbers 🥒 | 2 whole | Thinly sliced lengthwise, seeds removed |
| Mirin 🍶 | ¼ cup | High-quality, unsweetened preferred |
| Rice Vinegar 🍶 | ¼ cup | Seasoned preferred for extra flavor |
| Granulated Sugar 🍯 | 1 tbsp | Or substitute with honey |
| Toasted Sesame Seeds 🌰 | 1 tbsp | Freshly toasted for best flavor |
| Red Chili Flakes 🌶️ | ½ tsp | Adjust for heat preference |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| Ice Water ❄️ | 1 cup | For quick cucumber soak |

| Green Onion 🧅 | 2 whole | Thinly sliced, for garnish |
| Sesame Oil 🫒 | 1 tsp | Toasted sesame oil preferred |
The cucumbers are everything here. Japanese cucumbers are ideal—they're long, crisp, and seedless, but any firm cucumber works in a pinch. Look for ones that are bright green and heavy for their size at Trader Joe's or Whole Foods. If you can't find Japanese cucumbers, English cucumbers or Persian cucumbers are great substitutes. Slice them thinly with a sharp knife—about 1/8-inch thick—and soak in ice water for 10 minutes to remove excess moisture before draining. Trust me, this step makes all the difference in texture!
Mirin is non-negotiable for that signature sweet-tart balance, but no mirin? Substitute with 1/4 cup rice vinegar plus 1 tbsp honey. The sugar can be swapped for maple syrup or agave if you're avoiding refined sugar. For extra depth, add a pinch of Diamond Crystal kosher salt—it dissolves better than table salt. The sesame seeds should be toasted in a dry pan until golden for maximum flavor. If you can't find toasted sesame seeds, toast regular sesame seeds yourself—it takes 2 minutes and changes the game. Skip the ginger if you're sensitive to its sharpness, but it adds a lovely warmth that pairs perfectly with the cucumbers.
This salad keeps beautifully for 3-4 days in an airtight container in the fridge, though the texture softens slightly after day 2. For the best experience, serve it chilled—15 minutes in the fridge before eating lets the flavors meld. Garnish with green onions right before serving so they stay fresh and vibrant. The dressing can be made up to 3 days ahead and stored separately, but toss it with the cucumbers just before serving to keep everything crisp. It's perfect for meal prep—just portion into containers and grab as needed!

Step-by-step instructions for Japanese cucumber salad with mirin
Here's how to create this refreshing dish with perfect balance and texture every time.
Prepare the Cucumbers
Slice the 2 whole Japanese cucumbers lengthwise into thin strips, about ¼-inch thick. I like to use a sharp chef's knife and make even cuts for consistent texture. Remove the seeds by scraping them out with your fingernail or a spoon—this prevents a bitter taste and ensures each bite is crisp and refreshing.
Transfer the sliced cucumbers to a large bowl. Pour the 1 cup ice water over them and let them soak for 10 minutes. This step removes excess moisture and prevents the salad from becoming watery. After soaking, drain the cucumbers thoroughly using a colander, shaking gently to remove all excess water. Pat them dry with paper towels if needed—the drier they are, the crunchier your salad will be.
Create the Dressing
In a small bowl, whisk together the 0.25 cup mirin, 0.25 cup rice vinegar, and 1 tbsp granulated sugar until the sugar dissolves completely. This creates a sweet-tart base that perfectly complements the cucumbers. I always use seasoned rice vinegar for that extra umami depth—it makes a noticeable difference in the final flavor.
Add the 0.5 tsp salt, 0.5 tsp red chili flakes, and 1 tsp finely grated fresh ginger to the dressing mixture. Stir well to combine. The ginger adds a subtle warmth that pairs beautifully with the cool cucumbers, while the chili flakes give it just a hint of spice. Taste the dressing now—it should be balanced between sweet, tangy, and slightly spicy.
Combine and Marinate
Pour the dressing over the drained cucumber slices in the large bowl. Using clean hands or a spatula, gently toss everything together until the cucumbers are evenly coated. I find that tossing by hand gives the best texture—it prevents crushing the cucumbers while ensuring even distribution of the dressing.
Cover the bowl and let the salad marinate in the refrigerator for at least 30 minutes, or up to 2 hours for maximum flavor development. This resting time allows the cucumbers to absorb the dressing and soften just enough to enhance their natural sweetness without losing their crunch. The longer it marinates, the more pronounced the flavors become.
Garnish and Serve
Before serving, thinly slice the 2 whole green onions and sprinkle them evenly over the cucumber salad. Drizzle with the 1 tsp sesame oil and sprinkle the 1 tbsp toasted sesame seeds on top. The sesame oil adds a rich, nutty depth while the toasted seeds provide a satisfying crunch that contrasts beautifully with the soft cucumbers.
Gently toss the salad one final time just before serving to distribute the garnishes evenly. Serve immediately while still chilled for the perfect refreshing bite. This salad pairs wonderfully with grilled meats, sushi, or as a light standalone dish—especially on hot days when you crave something crisp and cooling.
Pro Tips For Making Japanese Cucumber Salad Recipe Mirin
- CHILL THE CUCUMBERS FIRST: Toss them in ice water for 10 minutes before slicing—this firms up the flesh and keeps it crisp longer. I learned this after serving a salad that turned soggy halfway through the meal.
- SALT THE CUCUMBERS BEFORE DRESSING: Sprinkle ½ teaspoon of salt over the sliced cucumbers and let sit for 5 minutes. Rinse and drain well—this removes excess water and makes the dressing cling better. Skipping this step means a watery, unbalanced salad.
- USE WARM MIRIN: Heat the mirin slightly (just until it steams) before mixing with vinegar and sugar. Warmth helps the sugar dissolve faster and blends the flavors more smoothly. Cold mirin can leave grainy bits—trust me, it’s noticeable.
- TOAST SESAME SEEDS LOW AND SLOW: Cook sesame seeds in a dry pan over medium-low heat, stirring constantly, until they’re golden—not brown. High heat burns them fast, and they turn bitter. A minute or two is all it takes, but watch them like a hawk.
Dietary considerations for this recipe
Vegetarian-Friendly Base
This Japanese cucumber salad is naturally vegetarian and packed with plant-based protein from sesame seeds—about 3 grams per tablespoon. The cucumbers provide hydration and fiber, while the mirin and rice vinegar dressing delivers a refreshing acidity that balances the meal perfectly.
It's an excellent side for veggie-centric meals or a light lunch on its own. 🥒
Gluten-Free Adaptations
All ingredients in this recipe are inherently gluten-free, but always double-check your mirin label—some brands contain wheat. I recommend Matsuhisa mirin or Kikkoman mirin, both certified gluten-free.
For extra safety, use tamari instead of regular soy sauce if you're sensitive to cross-contamination. The salad remains completely safe and delicious with these adjustments.
Low-Carb Options
This dish is naturally low-carb with only 5 grams of carbs per serving (without added sugar). Skip the granulated sugar entirely and rely on the natural sweetness of the mirin and cucumbers.
For even fewer carbs, omit the green onions—though they add minimal carbs and great flavor. The salad remains perfectly refreshing while fitting into keto or low-carb diets.
Allergen Considerations
Sesame is the primary allergen here, so if you're sensitive, simply omit the sesame seeds and sesame oil. The dish still maintains its refreshing qualities without these components.
For nut allergies, ensure your mirin is nut-free—some brands process in facilities with tree nuts. Always check labels when substituting ingredients to maintain safety.
Dietary Flexibility
This salad works beautifully in multiple dietary plans. For vegans, it's already plant-based—just ensure your mirin is vegan (some contain fish derivatives). For those watching calories, the dressing contains only about 15 calories per tablespoon, making it a guilt-free addition.
The crisp texture and bright flavors satisfy without overpowering other dishes in your meal.
Seasonal Adjustments
In summer, this salad is a cooling staple—serve it chilled as a refreshing starter. For winter, add ½ tsp grated daikon radish to the dressing for extra depth and a slight peppery kick. The mirin's sweetness helps balance any added heat or bitterness, keeping the dish versatile year-round. 🌿

Frequently asked questions
Can I use regular cucumbers instead of Japanese cucumbers?
Yes, you can! While Japanese cucumbers are seedless and extra crisp, English or Persian cucumbers work well too. Just be sure to remove all seeds and soak them in ice water for 10 minutes to remove excess moisture. The texture will be slightly different but still delicious.
What if I don't have mirin?
No problem! Mix ¼ cup rice vinegar with 1 tbsp honey or sugar for a similar sweet-tart balance. The flavor won't be identical, but it'll still taste amazing. For extra depth, add a pinch of soy sauce or fish sauce if you're not vegetarian.
How long can I store this salad before serving?
This salad keeps well in an airtight container in the fridge for 3-4 days, though texture softens slightly after day 2. For best results, marinate for 30 minutes before serving to let flavors meld. Store dressing separately if prepping ahead—toss just before eating to maintain crispness.
Can I make this salad spicier?
Increase the red chili flakes to 1 tsp or add ½ tsp sriracha to the dressing. For heat lovers, try 1 tsp gochujang (Korean chili paste) mixed with the mirin. Balance with extra sugar if needed—mirin's sweetness helps tame the spice.
What's the best way to serve this salad?
This refreshing dish pairs perfectly with grilled fish, sushi, or rice bowls. For a complete meal, serve with steamed rice and miso soup. Chill the salad for 15 minutes before serving to enhance flavors. Garnish with extra sesame seeds and green onions right before eating for maximum freshness.
