Korean Cucumber Salad

The first time I had this salad was at a tiny Korean BBQ spot in Los Angeles where the server kept refilling these small banchan plates. Every time I took a bite of that crunchy, spicy cucumber, I had to pause between conversations. It was the kind of refreshing thing that cuts through rich grilled meat like nothing else.

Last summer I made a huge batch for a potluck and people kept asking where I bought it. Someone actually thought I drove an hour to Koreatown just for the side dishes. That moment when you realize something this simple can impress a whole roomfull of people pretty great.

Ingredients

• 2 large English cucumbers (or 4-5 Persian cucumbers), thinly sliced: English cucumbers have thinner skin and fewer seeds, which means more crunch and less water in your final salad
• 2 green onions, finely sliced: These add a fresh, mild onion flavor that balances the heat
• 1 ½ tablespoons gochugaru (Korean red chili flakes): This is non-negotiable for authentic flavor, regular red pepper flakes are too bitter and sharp
• 1 tablespoon soy sauce: Use tamari if you need to keep it gluten-free, the flavor difference is minimal
• 1 tablespoon rice vinegar: Adds just enough brightness without being too acidic like white vinegar would be
• 1 tablespoon toasted sesame oil: The toasting matters, raw sesame oil lacks that deep nutty aroma
• 1 teaspoon sugar: Helps balance the salt and heat, plus it helps the dressing cling to the cucumbers
• 1 teaspoon minced garlic: Fresh is best here, jarred garlic can have a weird aftertaste in raw preparations
• ½ teaspoon salt: This is for drawing water out of the cucumbers first, not for seasoning the final dish
• 1 tablespoon toasted sesame seeds: Toast them yourself in a dry pan for 30 seconds, the flavor difference is huge

Instructions

Salt the cucumbers:

Place the sliced cucumbers in a bowl and sprinkle with salt, then toss well and let sit for 5 minutes to draw out excess water so the dressing does not get watered down later.

Drain and squeeze:

Drain the cucumbers and gently squeeze out any remaining liquid with your hands, being careful not to crush them completely.

Mix the dressing:

In a large mixing bowl, combine gochugaru, soy sauce, rice vinegar, sesame oil, sugar, and minced garlic, then stir until sugar is completely dissolved.

Combine everything:

Add the drained cucumbers and green onions to the bowl with the dressing, then toss everything together until every piece is evenly coated.

Finish and serve:

Transfer to a serving dish and sprinkle with toasted sesame seeds, serving immediately while the cucumbers still have that satisfying crunch.

Save

My friend who claims she hates spicy food ate three helpings of this at dinner once. She kept saying it was not that spicy but she was definitely sweating a little. Sometimes the best recipes are the ones that surprise people.

Making It Your Own

You can dial the heat up or down by adjusting the gochugaru, but do not go below one tablespoon or you lose that signature Korean flavor profile. If you want some sweetness, shredded carrot or even a tiny bit of grated apple works beautifully.

Storage Secrets

This salad is best eaten the same day because cucumbers release water over time. If you must refrigerate it, eat it within two days and give it a quick drain before serving because there will be liquid at the bottom of the container.

Serving Ideas

This salad pairs perfectly with grilled meats, rice bowls, or even just as a refreshing snack on its own. The cool crunch balances out any spicy or rich main dish.

• Try it topped over a bowl of warm rice with a fried egg
• Serve alongside kalbi or bulgogi for an authentic Korean BBQ experience
• Use it as a refreshing contrast to heavier fried foods

Save

Keep a jar of gochugaru in your pantry once you find a good brand, it will become your secret weapon for adding that Korean flavor spark to so many dishes beyond just this salad.

Recipe Questions & Answers

→ How long does Korean cucumber salad stay fresh?

Best enjoyed immediately for maximum crunch, but can be refrigerated for up to 2 days. The cucumbers may release more liquid over time.

→ What is gochugaru?

Gochugaru are Korean red chili flakes with a smoky, slightly sweet flavor. They're essential for authentic Korean seasoning and provide moderate heat.

→ Can I make this less spicy?

Reduce the amount of gochugaru to adjust heat level. Start with ½ teaspoon and taste before adding more.

→ Why salt the cucumbers first?

Salting draws out excess water from the cucumbers, preventing the dressing from becoming diluted and maintaining a satisfying crunch.

→ What type of cucumbers work best?

Persian cucumbers provide the best crunch, but English cucumbers work well too. Both have thin skins and minimal seeds.
