Cool and crisp with a bright tangy flavor this Japanese cucumber salad is my trusted secret side for hot days or anytime I want something fast and refreshing It is light enough for summer lunches yet full of that umami punch that keeps your chopsticks coming back
I first threw this together one night when I had only a few things left in my fridge It became an immediate favorite for its fresh crunch and simplicity
Ingredients
- Japanese or Persian cucumbers: These varieties are extra crisp with thin skins and minimal seeds Look for ones that feel firm and heavy for their size
- Salt: Draws out moisture to give perfect crunch and helps flavors soak in Use a fine sea salt for even distribution
- Rice vinegar: Gives signature brightness Choose unseasoned rice vinegar for a clean flavor
- Granulated sugar: Adds a gentle sweetness balancing the acidity of the vinegar Use fresh sugar for smooth dissolving
- Soy sauce: Delivers depth and that undeniable umami A low sodium soy sauce lets you better control saltiness
- Sesame seeds: Finish with these for subtle nutty flavor Toast them lightly for extra aroma
Instructions
- Prepare the Cucumbers:
- Slice Japanese or Persian cucumbers as thinly as possible Either use a sharp knife or a mandoline for best results This allows the salad to absorb dressing fully and gives an even crunch
- Salt and Rest:
- Sprinkle the sliced cucumbers with salt and toss well with your hands Let them stand in a large bowl for 10 minutes The salt will draw out excess water helping the cucumbers become extra crisp and making space for the dressing to soak in
- Mix the Dressing:
- Combine rice vinegar granulated sugar and soy sauce in a small bowl Whisk vigorously until the sugar dissolves completely You want a smooth mixture so every bite is even
- Drain and Squeeze Cucumbers:
- Gather the salted cucumbers and transfer them to a colander Let the liquid drain off then use both hands to gently but firmly squeeze as much remaining water as you can out of the cucumber slices This step is crucial so your salad is never watery
- Combine and Marinate:
- Return the drained and squeezed cucumbers to their bowl Pour the rice vinegar dressing over and toss gently with your hands or a spoon Make sure every cucumber slice is coated Allow the salad to marinate at room temperature for 10 minutes
- Finish and Serve:
- Sprinkle the salad generously with toasted sesame seeds Serve right away for the best snap and freshness or chill it for later eatings Both ways are delicious

My favorite part is watching how sesame seeds instantly bring the whole salad to life Once I made this for a family picnic and my niece loved it so much she insisted on sprinkling her own seeds on every portion

Store this salad in an airtight container in the refrigerator It will stay bright and crisp for up to three days though the sesame seeds are best added just before serving If storing for more than a day give it a gentle toss before enjoying to redistribute any collected dressing
Ingredient Substitutions
