Quick & Spicy: Korean Cucumber Salad in 30 Mins in 2025

You’re not alone if you’ve ever sat at a Korean restaurant and instantly fallen in love with those small, flavorful side dishes (a.k.a. banchan).

One of the standout stars is the spicy Korean Cucumber Salad, which features crisp, cool cucumbers bathed in a tangy, garlicky, sesame-infused dressing. That packs a gentle (or fiery!) punch.

This salad isn’t just refreshing, it’s a palate cleanser, a flavor booster, and an absolute must for Korean BBQ, rice bowls, or even just snacking out of the fridge.

So, what if I told you you could whip up this restaurant-style salad in under 30 minutes with ingredients you probably already have?

Let’s follow the easy step-by-step method to make this delicious Korean cucumber salad at home.

What Is Korean Cucumber Salad?

Korean Cucumber Salad, also known as Oi Muchim (오이무침), is a classic Korean side dish served cold and bursting with bold flavor. It’s commonly found as part of a Korean banchan spread, the small, flavorful side dishes that come out before or alongside your main meal.

This salad is all about balance. Imagine crunchy cucumbers soaked in a spicy, tangy, garlicky dressing that dances between sweet and savory. The heat comes from Korean chili flakes (gochugaru), vinegar brings the tang, and sesame oil adds nutty depth.

What makes it so special? It’s crisp, refreshing, and addictive, all at once. You can think of it as Korea’s answer to a punchy pickle salad, only faster to make and way more flavorful.

It’s perfect with grilled meats, rice bowls, or even on its own. Whether you’re already a fan of Korean cuisine or just dipping your toe into it, this cucumber salad is one of the easiest (and most satisfying) dishes to make at home.

Ingredients You’ll Need

Let’s go ingredient by ingredient, just like the video explained. You don’t need anything fancy, just a few pantry staples and a trip to your nearest Korean market (or the international aisle).

💡 Tip: You can find gochugaru at any Korean grocery store or online. It’s inexpensive and well worth having in your pantry.

Everything in this recipe works together to create a delicious balance of texture and flavor. Once you try it, you’ll see why this humble little salad is a beloved staple in Korean homes and restaurants.

Step-by-Step Guide to Making Korean Cucumber Salad (Oi Muchim)

Simple, quick, and flavorful – here’s how to make it perfectly every time.

Step 1: Partially Peel the Cucumbers

Let’s start with the cucumbers. You don’t want to peel the whole thing, but you don’t want to leave the skin completely intact.

So what’s the trick? Stripe peeling and it’s easier than it sounds.

Grab a vegetable peeler and make long strokes every other strip down the cucumber. The goal is to alternate peeled and unpeeled stripes like a zebra pattern.

Why? The cucumber skin has great texture and nutrients, but leaving it fully intact can make the salad too chewy. This striped peeling gives you the best of both worlds — crunchy texture with a softer bite.

💡 Use Persian or English cucumbers for best results. They have thin skin and tiny seeds, perfect for this salad.

Step 2: Slice Into Chunks

Once your cucumbers are beautifully striped, rinse them under cold water. Then, it’s time to chop them up.

You want the cucumbers to hold their shape, so slice them into thick coins or large chunks. Think “snackable” pieces—not too thin like pickles, but not so thick that they feel clunky.

Aim for pieces that are about 1/2 inch thick. When salted, these chunks will soften slightly but stay satisfyingly crisp in the final dish.

📏 Using English cucumbers? You’ll need about 2 large ones. For Persian cucumbers, use 7–8 small ones.

Step 3: Salt and Rest (The Secret Crunch Maker)

Here’s where the magic begins. You must salt the cucumbers and let them sit to get that signature Korean restaurant crunch.

Here’s how to do it:

• Place all your cucumber chunks into a big mixing bowl.
• Sprinkle a generous tablespoon of salt over them.
• Toss everything so the salt coats each piece evenly.

What’s happening here? The salt draws out excess water from the cucumbers through osmosis. This intensifies the cucumber flavor and keeps your salad from becoming a watery mess.

Let the salted cucumbers rest for 20 to 30 minutes at room temperature.

Don’t worry if they look overly salty, you’ll rinse them later.

🧂 Even if you over-salt, it’s okay! You’ll be washing off the salt in the next step.

Step 4: Rinse and Drain

Time to clean things up.

By now, your cucumbers should be looking a little wilted, not in a bad way. They’ll feel softer and slightly bendable, which means the salt did its job.

Do this:

1. Dump the cucumbers into a colander in your sink.
2. Rinse thoroughly with cold water, washing off all the salt.
3. Please give them a light squeeze or toss to remove any lingering water.
4. Let them sit in the colander for a few minutes to drain completely.

Once drained, taste a cucumber. It should be lightly salty. If it’s too salty, rinse again. Don’t worry if there’s no saltiness; the dressing will handle that.

💦 This step is crucial. Skipping the rinse will make your salad too salty and soggy.

Step 5: Mix the Flavor Bomb Dressing

While your cucumbers are resting or draining, whip up the show-stealing dressing.

You’ll need a small bowl and measuring spoons, or if you’re like me, your favorite long-handled spoon that happens to work.

Here’s the flavorful lineup:

• 1.5 tablespoons white vinegar – for that zingy tang.
• 1.5 tablespoons soy sauce – adds umami depth.
• 1.5 tablespoons sesame oil – nutty and aromatic.
• 2 tablespoons gochugaru (Korean chili flakes) – adds flavor and stunning red color.
• 2 cloves garlic, finely minced – packs in punchy heat.
• 1 teaspoon sugar – to balance everything out.

Whisk all this together until you get a bright red, slightly thick, spicy dressing that smells incredible.

Want to crank up the heat? The optional super-hot chili flakes are here. Mix them in now or wait until you portion the salad and add them to individual servings.

🌶️ Making it for a mixed crowd? Keep the dressing base mild and let spicy lovers add their heat.

Step 6: Toss It All Together

Now comes the fun part: assembling the salad.

Grab a clean mixing bowl and throw in:

• Your rinsed and drained cucumber chunks
• Thinly sliced onion (about 1 stalk — green or yellow, your choice)

Pour the spicy dressing over the top.

It’s a beautiful mess of red, green, and glossy sesame oil. Now, glove up if you’re sensitive to spice and mix everything well. Use your hands or tongs to coat every cucumber piece in that flavorful marinade gently.

🔥 Be sure everything is coated evenly. The chili flakes give this dish its iconic color and flavor.

Let it sit for 10 minutes after mixing so the cucumbers soak in all the flavor.

Step 7: Garnish Like a Pro

You’re almost there. Just a few finishing touches to take your salad from good to gourmet:

• Sprinkle with toasted sesame seeds for extra crunch and visual appeal.
• Drizzle with a little extra sesame oil if you like it nuttier.

And just like that, you’ve made a restaurant-worthy Korean cucumber salad at home!

🎉 Bright, bold, and full of life — this dish looks and tastes amazing.

Pro Tips for Korean Cucumber Salad Success

Want your Korean cucumber salad to taste restaurant-quality every time? Here are some tried-and-true tips from the kitchen:

✅ Use Fresh, Firm Cucumbers

Soft or overripe cucumbers make a mushy salad. Stick to firm, crisp cucumbers, such as Persian or English cucumbers.

🥒 Avoid large seeds or watery varieties unless you deseed them first.

🧂 Salt Generously – Then Rinse Well

Don’t be afraid to use a lot of salt in the resting stage; it’s essential for drawing out excess moisture. But rinse thoroughly, or your salad could turn out overly salty.

💡 TaTastefter rinsing, you want a subtle saltiness, not an overload.

⏳ Let the Salad Sit Before Serving

Once you mix everything, let the salad rest for 10–15 minutes. This gives the cucumbers time to absorb the dressing and develop deeper flavor.

🕒 It’s even better after chilling for 30 minutes.
