How to Make Japanese Cucumber Sunomono Easily

How to Make Japanese Cucumber Sunomono

Step 1: Prepare the Cucumbers

Begin by washing the cucumbers thoroughly. Use a mandoline, sharp knife, or vegetable peeler to slice the cucumbers as thinly as possible for the ideal texture. Lightly salt the slices and let them sit for 10-15 minutes to draw out excess water, ensuring your sunomono stays crunchy rather than watery.

Step 2: Make the Dressing

While the cucumbers rest, combine rice vinegar, sugar, soy sauce, and a pinch of salt in a small bowl. Stir until the sugar dissolves completely, forming a smooth, balanced dressing with a hint of sweetness and tang.

Step 3: Drain and Mix

After the cucumbers have released their water, gently squeeze the excess liquid out using your hands or a clean kitchen towel. Transfer the cucumbers to a mixing bowl and pour the dressing over them. Toss lightly to coat every slice evenly without mashing them.

Step 4: Add Optional Ingredients

If you’re using sesame seeds or wakame, sprinkle them in now. Toasting the sesame seeds beforehand intensifies their nutty aroma, and soaked wakame adds wonderful contrast and flavor.

Step 5: Chill and Serve

Refrigerate the salad for at least 15 minutes before serving. Chilling allows the flavors to meld together and enhances the refreshing qualities of this simple yet flavorful dish.

Pro Tips for Making Japanese Cucumber Sunomono

  • Choose fresh cucumbers: Fresher cucumbers provide better crunch and flavor, so avoid those with soft spots or wrinkled skin.
  • Slice cucumbers thinly: Thin slices absorb the dressing more effectively and create the classic delicate texture.
  • Salt properly: Salting helps remove excess moisture without making the cucumbers soggy when drained well.
  • Balance flavors: Adjust vinegar, sugar, and soy sauce quantities gradually to suit your taste preferences.
  • Chill before serving: Refrigeration deepens flavors and makes the salad extra refreshing.

How to Serve Japanese Cucumber Sunomono

Garnishes

Lightly toasted sesame seeds add a beautiful nutty flavor and subtle crunch, finishing the dish with an authentic touch. You can also sprinkle finely shredded nori or thin strips of fresh herbs like shiso or cilantro for a pop of color and aroma.

Side Dishes

Japanese Cucumber Sunomono pairs brilliantly with grilled fish, sushi, tempura, or teriyaki dishes. It serves as a palate cleanser and balances rich, oily foods with its crisp, acidic notes.

Creative Ways to Present

Serve this salad in small, decorative bowls or layered in clear glass cups for an elegant presentation. For a party, consider scooping it into cucumber cups or topping it with microgreens for an Instagram-worthy appetizer.

Make Ahead and Storage

Storing Leftovers

Store leftover Japanese Cucumber Sunomono in an airtight container in the refrigerator. It is best consumed within 1-2 days to maintain its fresh texture and vibrant flavor, as cucumbers tend to soften over time.

Freezing

Freezing is not recommended for this dish because cucumbers contain high water content, which becomes mushy and loses the characteristic crunch upon thawing.

Reheating

This salad is meant to be enjoyed cold and does not require reheating. Simply take it out of the fridge a few minutes before serving if preferred slightly less chilled.
