Korean Cucumber Salad

The first time I had this salad was at a tiny Korean restaurant in LA where the owner kept bringing out little banchan plates until I literally had to ask her to stop. This bright red cucumber salad was the one I kept reaching for between bites of grilled pork. Now I make a double batch because my family treats it like a proper side dish, not just a palate cleanser.

My brother in law once accidentally used regular paprika instead of gochugaru and the salad turned into something sad and dusty. That mistake taught me that the specific chili flakes matter. Now I keep a dedicated jar in my spice cabinet just for this recipe because honestly, its become the one dish everyone requests at summer cookouts.

Ingredients

• 2 large English cucumbers or 4-5 Persian ones: English cucumbers have thinner skins and fewer seeds but Persian ones stay crunchier longer so pick based on when youre planning to serve it
• 2 green onions finely sliced: Use both the white and green parts because the whites add bite while the greens bring fresh onion flavor
• 1 ½ tablespoons gochugaru: Korean chili flakes have this smoky sweetness that regular red pepper flakes just cant replicate
• 1 tablespoon soy sauce: Tamari works perfectly here if you need gluten free and honestly I cant taste the difference
• 1 tablespoon rice vinegar: White vinegar is too harsh and apple cider is too fruity so stick with rice vinegar for that clean brightness
• 1 tablespoon toasted sesame oil: The toasted version is non negotiable because plain sesame oil is practically flavorless
• 1 teaspoon sugar: This balances the salt and heat without making the salad taste like dessert
• 1 teaspoon minced garlic: Fresh garlic is worth the extra prep time over jarred minced stuff which can taste metallic
• ½ teaspoon salt: This draws water out of the cucumbers so they soak up the dressing instead of getting watery
• 1 tablespoon toasted sesame seeds: Toast them yourself in a dry pan for 2 minutes because store bought ones never taste as fresh

Instructions

Salt the cucumbers:

Slice the cucumbers thin and toss them with salt in a bowl. Let them sit for exactly 5 minutes and youll see water pooling at the bottom which is exactly what you want.

Drain and squeeze:

Pour the cucumbers into a colander and gently press them with your hands to get rid of that excess liquid. Dont go crazy or youll bruise the cucumbers but firm pressure is fine.

Mix the sauce:

Whisk together the gochugaru soy sauce rice vinegar sesame oil sugar and garlic until the sugar completely disappears.

Combine everything:

Add the drained cucumbers and sliced green onions to the sauce bowl. Toss with your hands or tongs until every slice is coated in that bright red mixture.

Finish and serve:

Sprinkle the sesame seeds on top right before serving because they lose their crunch if they sit in the sauce too long.

Last summer I made this for a potluck and two people asked for the recipe before they even finished their first helping. One friend told me she puts it on tacos now which sounds weird until you actually try it and then it makes perfect sense.

Making It Ahead

Ive learned that this salad actually gets better after a few hours in the fridge. The flavors meld together and the cucumbers soak up more of that spicy sweet dressing. Just dont add the sesame seeds until right before you serve them or theyll get soft and unappealing.

Adjusting The Heat

Some days I want mild and other days I want to feel my lips tingle so I always taste the sauce before tossing it with the cucumbers. Start with one tablespoon of gochugaru and add more if you want more fire because you cant take it back once its in there.

Serving Ideas

This salad works with pretty much any Asian inspired dish but its also perfect alongside grilled meats or even tucked into a rice bowl. The cool crunch balances out hot dishes and the acidity cuts through rich fatty foods beautifully.

• Pile it onto bulgogi burgers for this insane fresh crunch factor
• Mix it into plain rice for a quick lunch that actually has flavor
• Top it onto grilled fish for a spicy fresh element you didnt know you needed

This recipe taught me that sometimes the simplest side dishes are the ones people remember most. I hope it becomes your go to for quick bright flavor whenever you need it.

Recipe FAQs

→ How long does Korean cucumber salad keep?

Best enjoyed fresh within the same day for maximum crunch. Can be refrigerated for up to 2 days, though cucumbers may release more water over time.

→ Can I make this less spicy?

Yes, reduce the gochugaru amount to ½ teaspoon or omit entirely for a milder version. You can also remove seeds from the cucumbers for less bitterness.

→ What type of cucumbers work best?

Persian cucumbers are ideal for their crunch and thinner skin. English cucumbers work well too—just peel if the skin is thick.

→ Is this dish gluten-free?

Yes, simply use tamari instead of regular soy sauce. All other ingredients are naturally gluten-free.

→ Why salt the cucumbers first?

Salting draws out excess water from the cucumbers, preventing the dressing from becoming diluted and keeping the vegetables crunchy.
