I love this cucumber sunomono recipe because it’s so fresh and light, perfect for a quick snack or a side dish. It’s one of those dishes that feels simple but tastes really special, especially on warm days. I can’t wait for you to try it and see how the flavors come together!
Some ingredients like rice vinegar and toasted sesame seeds might not be in every kitchen, but you can find them easily at most supermarkets. Rice vinegar is a mild vinegar made from fermented rice, often found in the Asian foods aisle. Toasted sesame seeds add a nice nutty crunch and can usually be found near other seeds or spices.

Ingredients For Cucumber Sunomono Recipe
Cucumbers: Fresh and crisp, cucumbers are the main ingredient and give this dish its cool, crunchy texture.
Salt: Used to draw out excess water from the cucumbers, making them more flavorful and less watery.
Rice vinegar: A mild vinegar that adds a tangy and slightly sweet taste, essential for the dressing.
Sugar: Balances the vinegar’s acidity with a touch of sweetness.
Soy sauce: Adds a salty, savory depth to the dressing.
Toasted sesame seeds: Sprinkled on top for a nutty flavor and a little crunch.
Technique Tip for This Recipe
One of the most helpful steps in this Cucumber Sunomono Recipe is letting the cucumbers sit with the salt for a few minutes. Here’s how to do it right:
- After you thinly slice the cucumbers, sprinkle the salt evenly over them.
- Give the cucumbers a gentle toss so the salt spreads out and touches all the slices.
- Let them rest for about 5 minutes. During this time, the salt draws out extra water from the cucumbers.
- After the wait, you’ll notice some liquid at the bottom of the bowl. Drain that off before adding the vinegar mixture.
Why does this step matter? When you let the salt pull water out, the cucumbers become crunchier and don’t make your dish watery. It also helps the flavors soak in better, so your sunomono tastes fresh and bright instead of soggy.
I remember the first time I skipped this step because I was in a hurry. The cucumbers ended up swimming in liquid, and the texture was all wrong. Now, I always make sure to give the salt time to work its magic. If you want to save time, you can slice the cucumbers ahead and let them sit in the fridge with the salt while you prepare the other ingredients. It’s a little trick that makes the whole dish better without extra effort.
So, don’t rush this part—it’s a simple move that really makes your Cucumber Sunomono taste just right!

How to Store or Freeze This Dish
To keep your cucumber sunomono fresh and crisp, store it in an airtight container. This will help maintain its delightful crunch and prevent any unwanted flavors from mingling.
Place the container in the refrigerator. The cool environment will preserve the cucumbers and keep the vinegar mixture tasting vibrant and tangy.
For optimal freshness, enjoy your cucumber sunomono within 2-3 days. The longer it sits, the more the cucumbers will absorb the dressing, potentially losing some of their crispness.
If you wish to prepare the dish ahead of time, consider storing the cucumbers and the vinegar mixture separately. Combine them just before serving to ensure the cucumbers remain as crunchy as possible.
Freezing is not recommended for cucumber sunomono. The freezing process can alter the texture of the cucumbers, making them mushy and less appealing when thawed.
If you find yourself with an abundance of cucumbers, consider using them in other fresh dishes or pickling them separately for a different culinary adventure.
Always use a clean utensil when serving to avoid introducing any bacteria that could spoil your delightful cucumber sunomono.
How to Reheat Leftovers
Gently warm the cucumber sunomono by placing it in a heatproof bowl over a pot of simmering water. This indirect heat method will help maintain the crispness of the cucumbers while slightly warming the dish.
Use a microwave with caution. Place the cucumber sunomono in a microwave-safe dish, cover it with a damp paper towel, and heat on low power for 10-15 seconds. This method is quick but can make the cucumbers a bit softer.
If you prefer a room temperature option, simply remove the cucumber sunomono from the refrigerator and let it sit on the counter for about 15-20 minutes. This allows the flavors to meld without altering the texture too much.
For a refreshing twist, serve the cucumber sunomono cold, straight from the fridge. The crisp, chilled cucumbers can be quite delightful, especially on a warm day.
