Korean Cucumber Salad (오이무침) - Easy Banchan

Korean cucumber salad is one of the most popular Korean side dishes (banchan) served ahead of the main course.

The bright and refreshing taste goes well with BBQ meat, seafood, or rice dishes. You can also pair the Korean pickled cucumber with Kalbi, Pork tenderloin stir fry, and many more Asian entrees. 

Unlike Kimchi, this Korean cucumber salad doesn't require a fermentation process. You just need to mix the cucumber with the sauce ingredients and it can be served immediately.

Ingredients for Korean Pickled Cucumber

To make this Korean cucumber side dish, you'll need:

• cucumber. I used Persian cucumbers from Trader Joe's.
• rice wine vinegar. It's less acidic and sweeter than white distilled vinegar.
• sesame oil. It adds a delicious flavor and aroma to pickled cucumber.
• sugar and salt.  I used both sugar and salt to balance the tartness of the vinegar. 
• Korean red pepper flakes. Korean red pepper flakes are made of dried peppers that are chopped to a size between flakes and powder. Gochugaro has a mildly spicy taste, smoky flavor, and vibrant red color. It's also a little fruity.  You can find Korean red pepper flakes (aka Gochugaru) at any Asian grocery store, Vons, Ralph's, or online at Amazon.
• green onion. This is an optional ingredient.

If you can't find Gochugaru in your area, you can substitute it with other red pepper flakes (such as chipotle powder).

Please keep in mind that other red pepper flakes are probably spicier than Gochugaru. For that reason, you may need to use less of it and chop the red pepper flakes until they get powdery.

The Best Types of Cucumbers to Use for Korean Spicy Cucumber Salad 

Seedless and thin-skinned cucumbers are perfect for Korean Spicy Cucumber Salad. 

You can use medium-to-small-sized cucumbers, such as Kirby, Persian cucumber (aka Cocktail cucumber), or even long ones like English cucumbers. 

In this recipe, I used my favorite, which is Persian cucumbers. If your cucumber has a lot of seeds, you can remove the seeds beforehand to make the salad less watery.

Salting Cucumbers - The Secret to Keep Cucumbers from Getting Too Watery

The most important step in making your cucumber salad extra crunchy is that you have to salt the cucumbers to draw out as much liquid as possible.

This salting process is not complicated and can be done in minutes while you're preparing the other ingredients.

How to Make Korean Cucumber Salad

1. Prepare the Cucumber

• Rinse, dry, and slice the cucumber into ¼-inch rounds.

2. Salting the Cucumber 

• In a bowl, combine chopped cucumber with salt, then transfer it to a colander. Let the mixture sit for 30 minutes. 
• Rinse the cucumber with cold water to get rid of any excess salt so the salad won't be too salty. 
• Gently pat the cucumber dry with paper towels or clean kitchen towels to remove any excess water before mixing the sauce in. Don't squeeze the cucumbers as they are delicate!

2. Make the Dressing

• Mix all of the ingredients for the sauce until it's well combined. 

3. Season the Cucumber 

• Place the cucumber in a bowl, then pour in the sauce. Gently toss to combine.

How Long Do Korean Cucumbers Last in the Fridge?

You can keep the leftover cucumber salad in an airtight container.

Properly stored, it can last up to 3 days in the refrigerator. Any longer than that the cucumber will start losing its crispiness and freshness.
