Ingredients for japanese cucumber salad recipe mirin
Japanese restaurant-quality crunch meets umami harmony with these essential ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Japanese Cucumbers 🥒 | 2 whole | Seeded, sliced paper-thin |
| Mirin 🍶 | ¼ cup | Sweet cooking wine |
| Rice Vinegar 🍚 | ¼ cup | Unseasoned preferred |
| Soy Sauce 🥢 | 2 tbsp | Light or regular |
| Toasted Sesame Seeds 🌰 | 1 tbsp | Lightly toasted |
| Sesame Oil 🫒 | 1 tbsp | Light or dark |
| Granulated Sugar 🍚 | 1 tbsp | Adjust to taste |
| Green Onions 🌱 | 2 whole | Thinly sliced |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Fresh Ginger 🌿 | 1 tsp | Grated, optional |
The cucumbers are the foundation—Japanese long cucumbers (available at Asian markets) deliver the best texture, but regular cucumbers work in a pinch. Look for firm, unblemished specimens with vibrant green skin, as they hold up best during slicing. For the dressing, mirin is non-negotiable—it provides that signature sweetness and depth. San Jo brand is widely available in Asian grocery stores, but any quality mirin will do. The rice vinegar should be unseasoned to maintain precise flavor control. If you can't find it, substitute with apple cider vinegar but reduce the sugar slightly to balance the acidity.
Substitutions are flexible but require adjustments. No mirin? A blend of 1 tbsp sugar plus 1 tbsp water mimics its sweetness, though it lacks the complexity. Out of sesame oil? Avocado oil works but lacks the nutty aroma—use sparingly. No fresh ginger? A pinch of ground ginger (½ tsp) suffices, though it won't have the same fresh bite. For the cucumbers, salt them generously (½ tsp per pound) and let sit for 15 minutes to draw out excess moisture before draining. Skip the sugar? The mirin and soy sauce will still provide enough depth, but the dressing may taste sharper. Always taste as you go—this dish thrives on balance.
Prep ahead for maximum freshness: Slice the cucumbers and refrigerate for up to 2 hours before serving to enhance crispness. The dressing keeps for 5 days in the fridge, though it's best used within 3 days for optimal flavor. Store components separately—combine just before serving to maintain texture. For meal prep, portion the dressing and cucumbers in airtight containers, keeping them chilled until ready to assemble. The salad holds well for 3 days when properly stored, making it ideal for lunches or side dishes throughout the week.
Why You'll Love This Recipe
- No-Chop Nightmare: I swear by this one—just slice the cucumbers thinly (or buy pre-sliced if you’re really lazy), toss them in the dressing, and you’re done. The mirin and rice vinegar do all the flavor work while you’re scrolling through your phone.
- Umami Magic: That little splash of mirin? It’s the secret weapon. Sweet, tangy, and just salty enough from the soy sauce—it turns a simple cucumber into something dangerously addictive. Honestly, the first time I made it, I ate half the bowl before dinner.
- Picnic or Potluck Hero: This salad travels like a dream—no wilting, no spills, just crisp cucumbers that stay fresh for hours. Bring it to a BBQ, toss it in a bento box, or eat it straight from the fridge after a long day. It’s my go-to for any gathering where I don’t want to fuss.
- Budget Brightener: Japanese cucumbers might look fancy, but they’re cheaper than avocados and last longer in the fridge. A few tablespoons of mirin and soy sauce stretch to feed four, and the sesame seeds add crunch without breaking the bank. Leftovers? They keep for days—if they last that long.
Step-by-step instructions for Japanese cucumber salad with mirin
This refreshing salad balances crisp cucumbers with umami-rich mirin and aromatic sesame.
Prepare the Japanese Cucumbers
Begin by thoroughly washing the 2 whole Japanese cucumbers under cool water to remove any surface dirt. Using a sharp mandoline or thin vegetable slicer, slice them paper-thin—aim for slices so delicate they're nearly translucent. I like to stack the cucumbers and slice them all at once for perfect evenness.
Arrange the slices on a clean kitchen towel and sprinkle lightly with the 0.5 teaspoon kosher salt. Let them sit for 5 minutes while you prepare the dressing. This brief salting draws out excess moisture, preventing a watery salad. After 5 minutes, gently pat the cucumbers dry with another clean towel to remove any residual liquid.
Create the Umami Dressing
In a small bowl, combine the 0.25 cup mirin, 0.25 cup rice vinegar, 2 tablespoons soy sauce, and 1 tablespoon granulated sugar. Whisk vigorously for 30 seconds until the sugar fully dissolves and the mixture becomes smooth. The mirin will add natural sweetness while the rice vinegar provides bright acidity—this balance is essential for authentic flavor.
Add the 1 teaspoon freshly grated ginger and 1 tablespoon sesame oil to the dressing mixture. Stir well to incorporate the ginger's zesty aroma and the nutty richness of the sesame oil. Let the dressing sit for 2 minutes to allow the ginger to infuse its flavor into the mixture fully.
Assemble the Salad
Transfer the prepared cucumber slices to a large serving bowl. Thinly slice the 2 whole green onions and scatter them evenly over the cucumbers. Pour the dressing mixture over the cucumbers and green onions, using a silicone spatula to gently toss everything together. Be careful not to overmix—just enough to combine all ingredients without breaking the delicate cucumber slices.
This is where the magic happens: the acidity of the dressing will make the cucumbers slightly wilt, creating that perfect al dente texture we want. Let the salad sit for 10 minutes at room temperature before serving to allow the flavors to meld completely.
Finish and Serve
Sprinkle the 1 tablespoon toasted sesame seeds evenly over the salad just before serving. The seeds add a delightful crunch and visual contrast to the soft cucumbers. Taste the salad and adjust seasoning if needed—you might want to add a touch more sugar or soy sauce to achieve the perfect balance of sweet, salty, and umami flavors.
Serve immediately while the cucumbers still maintain their crisp texture. This salad pairs beautifully with grilled fish, sushi, or as a refreshing side to any Japanese-inspired meal. The combination of cool cucumbers and aromatic dressing creates a refreshing contrast that's perfect for warm weather or as a palate cleanser between rich dishes.
Pro Tips For Making Japanese Cucumber Salad Recipe Mirin
- CHILL THE CUCUMBERS FIRST: Japanese cucumbers are crisp but watery raw—cut them, then toss in ice water for 10 minutes before draining. This stops them from turning mushy when mixed with the dressing. (Yes, even if you're impatient like me, this makes a real difference.)
- USE COLD MIRIN DIRECTLY: Skip the warming step—just grab the bottle straight from the fridge and pour it in. The chilled mirin balances the acidity better, and you won’t accidentally overcook the cucumbers. (I learned this the hard way when my salad turned bland.)
- SAVE THE SOY SAUCE FOR LAST: Add soy sauce only after the cucumbers have soaked in the mirin and vinegar for 5 minutes. This keeps the dressing from turning dark and bitter too soon. (Your future self will thank you.)
- TOAST SESAME SEEDS IN A DRY PAN: Heat sesame seeds in a dry pan over medium-low for 2–3 minutes, stirring constantly, until they’re golden and smell nutty. No oil needed—just watch them like a hawk. (This isn’t the prettiest method, but it’s the tastiest.)
Make-ahead tips for this japanese cucumber salad recipe mirin
Prep Ahead Components
Slice the cucumbers and store them in an airtight container with a paper towel to absorb excess moisture. I like to refrigerate them for up to 2 hours before assembling—they develop that perfect crispness without turning soggy.
The dressing can be made 1 day in advance and kept in a sealed jar in the fridge. Just give it a quick stir before using to maintain its vibrant flavors. 🥒
Dressing Prep Tips
Measure out all dressing ingredients in advance and store them in a small mason jar with a tight-fitting lid. This keeps everything organized and ready to whisk together in seconds.
I often double the dressing recipe and freeze half in an ice cube tray—perfect for quick salads later in the week. Thaw overnight in the fridge before use. 🍶
Assembly Timing
Combine the cucumbers and dressing just before serving to preserve that ideal crisp-tender texture. If prepping for a meal, store components separately: cucumbers in one container, dressing in another.
When ready to serve, toss everything together and let it sit for 10 minutes at room temperature. This brief resting time allows flavors to meld beautifully. ✨
Portioning for Meals
Divide the salad into individual serving containers for easy grab-and-go lunches. I recommend using glass containers with snap lids—they maintain freshness better than plastic. Store the dressing separately and add it just before eating.
This keeps the cucumbers crisp for up to 3 days in the refrigerator. Perfect for busy weekdays! 📅
Freezing Options
While the cucumbers don't freeze well, you can freeze the dressing for up to 3 months. Store it in a freezer-safe bag, leaving 1 inch headspace for expansion.
Thaw overnight in the fridge and whisk to restore smoothness. For a quick version, freeze dressing in 1-tablespoon portions—ideal for single servings. 🧊
Garnish Freshness
Toast the sesame seeds just before serving to preserve their crispness. Store them in a small jar with a tight lid at room temperature.
The green onions can be prepped in advance and kept in the fridge for up to 5 days, stored in a sealed container with a damp paper towel to maintain freshness. 🌱

Frequently asked questions
Why does the recipe call for Japanese cucumbers instead of regular cucumbers?
Japanese cucumbers (also called Kyoto cucumbers) have thinner, more tender skin and fewer seeds, which creates that signature crisp texture. Regular cucumbers work in a pinch but may be slightly larger and less tender—slice them even thinner and salt them longer (10-15 minutes) to draw out extra moisture.
Can I make this salad without mirin? What's the best substitute?
Yes! For every 1 tablespoon of mirin, mix ½ tablespoon sugar with ½ tablespoon water to mimic its sweetness. However, mirin adds depth—try adding ½ teaspoon grated ginger or a pinch of MSG for extra umami if substituting.
How do I get the cucumbers extra crisp? They always turn soggy!
Salt the cucumbers generously (½ teaspoon per pound) and let them sit for 10-15 minutes in a colander. Pat them very dry with paper towels, then refrigerate for 1 hour before tossing with dressing. Store the salad in an airtight container with a paper towel to absorb any remaining moisture.
Is this salad spicy? Can I add chili flakes?
Not traditionally, but you can absolutely add a pinch of chili flakes or a dash of sriracha for heat! Start with ¼ teaspoon and adjust to taste. For a smoky twist, add ½ teaspoon toasted chili oil to the dressing before tossing.
How long does this salad keep? Can I make it ahead?
Store components separately: cucumbers (in an airtight container with paper towels) and dressing (in a sealed jar) for 3 days in the fridge. Combine just before serving to maintain crispness. The dressing alone lasts 5 days—freeze it in 1-tablespoon portions for quick salads later!
