How to Make It
- Thinly slice the cucumbers using a knife or spiralizer. Please place them in a bowl and toss with salt. Let sit for 10 minutes to draw out excess moisture.

Tips for the Best Korean Banchan Experience
- Slice your cucumbers evenly for a consistent crunch.
- Use chili oil with chili flakes for extra color and depth.
- Letting the salad rest helps the flavors meld beautifully.
- Mini cucumbers or Persian cucumbers work best for a delicate texture, but regular ones are fine in a pinch.
Behind the Banchan: A Personal Bite
The first time I had Korean cucumber salad, it was nestled beside a bubbling pot of kimchi stew at a tiny Korean diner. I thought it would be the underdog on the plate, but it stole the show. I’ve been hooked ever since. Now, I keep a jar in the fridge to pair with grilled chicken or to snack on straight from the bowl. It’s the kind of dish that quietly becomes a staple.
What to Serve with Korean Cucumber Salad
This Korean banchan plays well with everything from Korean BBQ and fried rice to baked salmon or simple noodle dishes. It adds a cool, crunchy contrast to rich or spicy mains. Pair it with bibimbap, bulgogi, or even a Western-style grilled cheese for a fusion twist. Trust me—it works!
How to Store Leftovers
Store the salad in an airtight container in the refrigerator for up to 3 days. The cucumbers will soften slightly, but the flavor will deepen. Stir before serving to redistribute the dressing.
FAQs About Korean Cucumber Salad
Can I make this ahead of time?
Yes! In fact, it tastes even better after sitting in the fridge for an hour.
What kind of cucumbers work best?
Mini or Persian cucumbers have a great crunch, but English or standard cucumbers work too—just peel and de-seed if needed.
Is this very spicy?
You control the heat! Start with 2 tsp of chili oil and adjust from there.
Can I make this without chili oil?
Absolutely. Substitute with sesame oil and a pinch of red pepper flakes or go completely mild for a refreshing version.
