Salads
This Japanese cucumber salad recipe with mirin transforms simple cucumbers into delicate, crisp ribbons bathed in a bright sweet-tangy dressing. The secret lies in blanching the cucumbers just enough to soften them slightly while preserving their signature crunch—no soggy salads here.
I developed this recipe after discovering how a proper balance of mirin, rice vinegar, and sugar could elevate humble cucumbers into a dish worthy of any bento box.
The technique is straightforward but precise: thinly slice cucumbers into ribbons (no peeling needed), blanch them briefly in boiling water, then shock in ice water to lock in their crisp texture.
The dressing combines mirin for sweetness, rice vinegar for acidity, and a touch of sesame oil for depth—all mixed until perfectly balanced. This isn't just a side dish; it's a flavor experience that bridges traditional Japanese techniques with modern adaptability.
What you'll end up with is a salad that's visually stunning—pale green ribbons against a glossy dressing—and packed with contrasting textures: crisp cucumbers, toasty sesame seeds, and a subtle heat from optional chili flakes. The dressing clings to each ribbon, creating bites that are both refreshing and satisfying.
It's the kind of dish that works as a light lunch, side for grilled fish, or elegant addition to a summer spread.
Ready in just 20 minutes, this recipe delivers restaurant-quality results with minimal effort. The key is patience—letting the dressing sit with the cucumbers for at least 10 minutes allows flavors to meld perfectly.
Serve immediately for that signature crunch, or chill for up to 4 hours if you prefer a more integrated texture. Here's everything you need to make it.
Ingredients for japanese cucumber salad recipe mirin
Transform simple cucumbers into delicate ribbons with these precise ingredients for crisp, restaurant-quality Japanese salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Japanese Cucumbers 🥒 | 2 lb | Thinly sliced into ribbons |
| Mirin 🍶 | ¼ cup | High-quality, sweet rice wine |
| Rice Vinegar 🍶 | ¼ cup | Seasoned preferred for depth |
| Granulated Sugar 🍚 | 2 tbsp | Adjust for sweetness preference |
| Toasted Sesame Oil 🫒 | 1 tbsp | For nutty aroma |
| Toasted Sesame Seeds 🌾 | 1 tbsp | Lightly toasted for crunch |
| Red Chili Flakes 🌶️ | ½ tsp | Optional for subtle heat |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Ice Water 💧 | 1 cup | For blanching shock |
The cucumbers are the star, so choose Japanese long cucumbers if available—they're less seedy and slice beautifully into ribbons. Most Asian grocery stores carry them, but regular cucumbers work in a pinch (just remove seeds). For the mirin, Hakkaisan or Itoham brands deliver authentic flavor—avoid cheap imitations. The rice vinegar should be seasoned (like Kikkoman) for that subtle umami kick. Toast your sesame seeds in a dry pan for 30 seconds until fragrant—that nutty aroma makes all the difference.
No mirin? Substitute 2 tbsp sugar plus 1 tbsp water to mimic sweetness, though you'll lose some depth. For vinegar, apple cider vinegar works but lacks the delicate acidity of rice vinegar. Skip the sesame oil? Light olive oil is a neutral swap, though it won't toast like sesame. The chili flakes are optional but worth it for that subtle heat. Pro tip: If your cucumbers are extra watery, pat them dry before slicing—no soggy salad here.
Blanched cucumbers keep their crisp texture best when served immediately, but they'll last 2-3 hours in the fridge if stored in a sealed container with dressing. The dressing itself stays fresh for 5 days in the fridge—make extra for quick lunches. For best results, let the salad sit 10 minutes before serving so flavors meld. The sesame seeds should be toasted fresh each time for maximum crunch—microwave 20 seconds if you're short on time.

Step-by-step instructions for Japanese cucumber salad
Here's how to create crisp, refreshing cucumber ribbons with a perfectly balanced dressing.
Prepare the Japanese Cucumbers
Start by thoroughly washing the 2 lb Japanese cucumbers under cold running water to remove any dirt or residue. Using a sharp mandoline or vegetable peeler, slice the cucumbers into thin ribbons—about ⅛-inch thick. I like to work in batches to keep the process efficient while maintaining consistency in thickness.
Place the sliced cucumbers in a large bowl and sprinkle evenly with the 0.5 tsp salt. Toss gently to distribute the salt, then let them sit for 10 minutes. This step draws out excess moisture, which is crucial for achieving crisp ribbons that won't turn soggy. After the waiting period, drain any accumulated liquid and pat the cucumbers dry with paper towels.
Blanch the Cucumber Ribbons
Bring the 1 cup ice water to a gentle simmer in a medium saucepan. Working in batches to avoid overcrowding, add the prepared cucumber ribbons to the simmering water. Let them cook for exactly 30 seconds—this brief blanching preserves their crisp texture while softening slightly for better flavor absorption.
Immediately drain the cucumbers in a colander and transfer them to a large bowl filled with fresh ice water for 1 minute. This ice bath shocks the cucumbers, halting the cooking process and locking in their crispness. Drain thoroughly once more and set aside on a clean kitchen towel to dry completely. This step is essential for achieving that signature crunch.
Create the Sweet-Tangy Dressing
In a small bowl, whisk together the 0.25 cup mirin, 0.25 cup rice vinegar, and 2 tbsp granulated sugar until the sugar dissolves completely. This combination creates a harmonious balance of sweetness and acidity that complements the cucumbers perfectly. Taste the mixture and adjust the sugar to your preference—you want it to be slightly sweet but not cloying.
Next, stir in the 1 tbsp toasted sesame oil and 0.5 tsp red chili flakes (if using). The sesame oil adds a rich, nutty depth, while the chili flakes introduce a subtle warmth that enhances the overall flavor profile. Mix well to ensure all ingredients are fully incorporated and the dressing is smooth.
Combine and Finish the Salad
Add the blanched cucumber ribbons to the dressing and toss gently to coat evenly. Let the salad marinate for 10 minutes at room temperature, allowing the flavors to meld together. This resting period ensures that the dressing fully infuses the cucumbers, creating a cohesive and delicious dish.
Just before serving, sprinkle the salad with 1 tbsp toasted sesame seeds for added texture and visual appeal. Toss lightly to distribute the seeds evenly. Serve immediately while the cucumbers are still crisp and the dressing is vibrant. This salad pairs beautifully with grilled meats, sushi, or as a refreshing side dish on its own.
Pro Tips For Making Japanese Cucumber Salad Recipe Mirin
- CHILL THE CUCUMBERS: Toss them in ice water for 10 minutes first—this firms up the flesh and cuts down on the bitterness that sneaks into overripe slices. I learned this the hard way after serving a salad that tasted like a science experiment gone wrong.
- USE COLD SESAME OIL: Warm toasted sesame oil loses its nutty punch fast, so add it last—right before serving—when everything’s already chilled. That way, you get the full aroma without it turning into a sad, flat afterthought.
- MEASURE THE MIRIN: Skip the eyeballing—mirin’s sweetness is potent, and too much turns your salad into dessert. Use 2 tablespoons for every 2 cups of cucumber slices, then adjust sugar to taste. (Yes, even if the recipe says otherwise.)
- DRAIN WELL AFTER SLICING: Pat the cucumbers dry after cutting, or your dressing will pool like a sad little lake instead of clinging to the slices. A clean kitchen towel or paper towels work—just don’t skip it, or you’ll end up with soggy, flavorless mush.
Flavor customization for this dish
Sweetness Levels
Mirin is the star of this dressing, but you can adjust sweetness to taste. For a milder version, reduce sugar to 1 tbsp and increase mirin to ⅓ cup—this keeps the dressing bright and less cloying.
If you prefer extra sweetness, add 1 tsp honey or 1 tsp maple syrup to the dressing for a deeper caramel note.
I’ve found that Hakkaisan mirin (with its lower sugar content) works best for balance, but if using cheaper mirin substitutes, you’ll need to add 1 extra tbsp sugar to compensate. 🍯
Acidity Adjustments
The rice vinegar provides the tangy backbone, but you can tweak it based on preference. For a sharper bite, add 1 tsp extra rice vinegar or ½ tsp lemon juice—this cuts through the sweetness beautifully.
If the acidity feels too strong, balance it with ½ tsp sugar or a splash of water (1 tsp) to dilute slightly. For a fermented twist, swap 2 tbsp rice vinegar for 1 tbsp unseasoned rice vinegar and 1 tbsp apple cider vinegar—this adds complexity. 🍋
Heat Variations
Chili flakes add subtle warmth, but you can customize the heat level. For mild heat, reduce to ¼ tsp or use ½ tsp gochugaru (Korean chili flakes) for a smoother spice.
For bold heat, add ½ tsp finely chopped fresh chili (like serrano) or 1 tsp sriracha to the dressing. If you love smoky heat, toast the chili flakes in a dry pan for 30 seconds before adding—they’ll release a deeper, toasty aroma. 🌶️
Herb Infusions
Fresh herbs elevate this salad with bright, aromatic notes. For a classic touch, add 1 tbsp finely chopped mint or cilantro—both pair beautifully with the dressing. For an earthy depth, try 1 tsp chopped shiso leaves (common in Japanese cuisine) or 1 tsp chopped dill.
If using herbs, add them just before serving to preserve their freshness and vibrant color. Pro tip: Lightly bruise the herbs by chopping them finely and letting them sit for 2 minutes before adding—they’ll release more flavor. 🌿
Umami Boosters
To deepen the dressing’s complexity, incorporate umami-rich ingredients. A dash of soy sauce (½ tsp) or 1 tsp fish sauce (for non-vegetarian versions) adds savory depth. For a vegan option, use 1 tsp mushroom powder or 1 tsp nutritional yeast.
Another trick? Toast ½ tsp white sesame seeds in the pan with the chili flakes—they’ll add a nutty, toasty umami punch. These tweaks make the salad even more satisfying. 🍜
Texture Contrasts
Crunch is key, but you can play with textures for extra dimension. For creamy contrast, fold in ¼ cup crumbled soft tofu or avocado slices just before serving. For crunchy contrast, add 2 tbsp toasted panko crumbs or crushed peanuts—both add a satisfying bite.
If you love chewy textures, try 1 tbsp finely chopped nori strips for a seaweed twist. These additions keep every bite exciting. 🥜

Frequently asked questions
Why do we blanch the cucumbers instead of eating them raw?
Blanching removes excess moisture and softens the cucumbers just enough to absorb the dressing beautifully while keeping them crisp. This technique prevents a watery salad and creates those signature delicate ribbons that stay firm. The brief 30-second boil followed by ice water shock is key to maintaining texture.
Can I make this salad ahead of time?
Yes, but with a time limit! The dressing works best when mixed with cucumbers right before serving for maximum crunch. If prepping ahead, store the blanched cucumbers and dressing separately in the fridge for up to 4 hours. Combine just before eating to preserve texture. For longer storage, the dressing alone keeps for 5 days—just add fresh cucumbers when ready.
What's the best way to slice cucumbers for this recipe?
Use a sharp mandoline or vegetable peeler to create thin, even ribbons about ⅛-inch thick. For Japanese cucumbers, slice lengthwise to create long, elegant strands. Regular cucumbers work too—just remove seeds first. The key is consistency: uniform slices ensure even cooking and dressing absorption.
Is mirin essential, or can I substitute it?
Mirin adds that signature sweetness and depth, but you can substitute with 2 tbsp sugar + 1 tbsp water if needed. For better results, use 1 tbsp sugar + 1 tbsp dry white wine to mimic mirin's complexity. Just note that the flavor won't be identical—mirin's natural sweetness and slight acidity are hard to replicate perfectly.
How do I prevent the salad from getting soggy?
Three key steps:
- Pat cucumbers completely dry after blanching,
- Store components separately if making ahead, and
- Serve immediately after tossing. Avoid adding dressing too early—wait until 10 minutes before serving to maintain that perfect crunch. The ice water shock during blanching also helps lock in crispness.
