The Roots of Korean Cucumber Salad
Korean side dishes, known as banchan, are integral to Korean meals. Among these, cucumber salads have a special place due to their crunch, refreshing taste, and ability to balance spicy or fatty dishes. Traditionally, Korean cucumber salads are lightly fermented or marinated with soy sauce, garlic, and red pepper flakes (gochugaru), giving them a unique flavor that’s both tangy and savory.
The use of gochugaru is particularly significant—it’s a Korean red pepper flake with a slightly fruity and smoky flavor, much different from standard chili flakes. Combined with sesame oil and vinegar, it transforms ordinary cucumbers into a flavor-packed dish that’s refreshing yet bold.

Step-by-Step Instructions for the Perfect Salad
Step 1: Slice the Cucumbers
Wash and thinly slice cucumbers into 1/4-inch rounds. Place in a large mixing bowl. Uniform slicing ensures even flavor absorption.
Step 2: Add the Aromatics
Thinly slice the white onion, chop green onions, and mince fresh garlic. Add to the cucumber bowl.
Step 3: Prepare the Dressing
In a small bowl, whisk together soy sauce, rice vinegar, sugar, gochugaru, sesame oil, sesame seeds, and a pinch of salt until well combined. The balance of sweet, salty, tangy, and spicy flavors is key here.
Step 4: Combine and Toss
Pour the dressing over the cucumbers and onions. Toss thoroughly using clean hands or tongs, ensuring every piece is coated.
Step 5: Let It Rest
Allow the salad to rest for 5–10 minutes for flavors to meld. Serve chilled or at room temperature.
Pro Tip: Resist the urge to pre-mix too early—cucumbers can release water, diluting the dressing.
