Korean Cucumber Salad Recipe (with Video)

Korean Cucumber Salad Recipe: Korean Cucumber Salad, also known as “Oi Muchim” in Korean, is a refreshing and spicy side dish that’s loved for its crunchy texture and zesty flavor. It’s typically made with thinly sliced cucumbers that are marinated in a mixture of gochugaru (Korean red pepper flakes), garlic, vinegar, and sesame oil. It’s incredibly simple to make, yet bursting with flavor that dances on your taste buds. Whether you’re a Korean food enthusiast or just looking for a quick and healthy snack, this salad is an absolute must-try.

This salad is categorized under “banchan” — the variety of small side dishes served along with cooked rice in Korean cuisine. It’s not only popular in Korean households but also a staple offering at Korean BBQ restaurants. Unlike Western salads that may require multiple types of greens and a complex dressing, Oi Muchim stands out for its minimalist approach and bold flavors.

Why It’s So Popular?

The popularity of Korean Cucumber Salad comes down to its unique combination of simplicity, flavor, and health benefits. For one, cucumbers are naturally hydrating and low in calories, making them a great option for weight-conscious eaters. Secondly, the seasoning mix — especially with ingredients like garlic, sesame oil, and gochugaru — delivers a punch of umami and spice that’s addictively delicious.

Additionally, this dish is versatile. It can be served as an appetizer, a side dish, or even a light snack. And because it’s so easy to make, it’s a favorite among busy home cooks. The vibrant red color from the gochugaru, combined with the fresh green of cucumbers, makes it visually appealing too — perfect for brightening up any dining table.

Ingredients You’ll Need

Fresh Ingredients for Maximum Flavor

To make a traditional Korean Cucumber Salad, you don’t need a long shopping list. Most ingredients can be found in your pantry or a local Asian grocery store. Here’s what you’ll need:

  • 2 to 3 Korean cucumbers (or English cucumbers if unavailable)
  • 1 teaspoon salt
  • 1 tablespoon Korean red pepper flakes (gochugaru)
  • 2 cloves garlic, minced
  • 1 tablespoon soy sauce
  • 1 tablespoon rice vinegar
  • 1 teaspoon sugar
  • 1 tablespoon sesame oil
  • 1 teaspoon toasted sesame seeds
  • 1 green onion, finely chopped

Each of these ingredients plays a vital role in delivering the perfect balance of salty, spicy, tangy, and savory. Gochugaru, for instance, gives it that unmistakable Korean flavor and a mild heat that’s not overpowering. If you can’t find Korean cucumbers, opt for English cucumbers as they have fewer seeds and a tender skin that doesn’t need peeling.

Optional Add-ins and Variations

If you’re in the mood to experiment, there are a few optional ingredients you can add to customize your salad:

  • Julienned carrots – for extra crunch and color
  • Thinly sliced onions – adds a sharp bite
  • Chili oil – for an extra layer of spiciness
  • Fish sauce – for deeper umami
  • Fresh herbs like cilantro or mint – to give it a twist

Feel free to adjust the spice level according to your taste. Some like it fiery hot, while others may prefer a milder version. That’s the beauty of homemade salads — you’re in complete control!

Step-by-Step Preparation Guide

Step 1 – Wash and Slice the Cucumbers

First things first: give your cucumbers a good rinse under cold water. You don’t need to peel them, especially if you’re using Korean or English cucumbers, which have thin, delicate skin. Pat them dry with a paper towel.

Slice the cucumbers into thin rounds or half-moons, depending on your preference. If you’re serving them as a snack or side dish, half-moons give a bit more bite. The key here is consistency — make sure the slices are uniform to ensure even salting and seasoning.

Now that your cucumbers are sliced and ready, it’s time to prep them for seasoning.

Step 2 – Salt and Drain the Cucumbers

Place the sliced cucumbers in a large mixing bowl and sprinkle them with about a teaspoon of salt. This step might seem simple, but it’s crucial. Salting the cucumbers draws out excess moisture, which helps maintain their crunch once they’re dressed with the marinade.

Let the cucumbers sit for about 15–20 minutes. You’ll notice they start to sweat — that’s a good thing! After that, gently squeeze out the excess water using your hands or a clean kitchen towel. Don’t over-squeeze them into mush; just press enough to remove the moisture.

This step ensures your salad won’t turn watery later, and the cucumbers will better absorb all the flavors from the dressing.

Step 3 – Prepare the Seasoning Mix

Now that your cucumbers are prepped and ready, it’s time to craft the flavorful seasoning that gives this salad its signature taste. In a mixing bowl, combine the following ingredients:

  • 1 tablespoon Korean red pepper flakes (gochugaru)
  • 2 cloves garlic, minced
  • 1 tablespoon soy sauce
  • 1 tablespoon rice vinegar
  • 1 teaspoon sugar
  • 1 tablespoon sesame oil
  • 1 teaspoon toasted sesame seeds
  • 1 green onion, finely chopped

This combination of ingredients creates a harmonious blend of spicy, savory, tangy, and nutty flavors. The gochugaru provides a gentle heat and vibrant red color, while the garlic adds a pungent kick. Soy sauce and rice vinegar balance each other out with their salty and acidic notes, and the sugar introduces a subtle sweetness. Sesame oil imparts a rich, toasty aroma, and the sesame seeds contribute a delightful crunch. The green onion adds a fresh, slightly sharp flavor that ties everything together.

Whisk these ingredients together until the sugar dissolves and the mixture is well combined. This seasoning mix is the heart of the Korean cucumber salad, infusing the cucumbers with bold and refreshing flavors.

Step 4 – Mix Everything Together

With your cucumbers drained and your seasoning mix prepared, it’s time to bring everything together. Place the cucumbers into a large mixing bowl and pour the seasoning mix over them. Using clean hands or a pair of tongs, gently toss the cucumbers until they are evenly coated with the seasoning.

Be careful not to overmix or apply too much pressure, as cucumbers are delicate and can become mushy if handled roughly. The goal is to ensure that each slice is well-coated with the flavorful seasoning without compromising their crisp texture.

Once mixed, let the salad sit for about 10 to 15 minutes. This resting period allows the cucumbers to absorb the flavors of the seasoning, enhancing the overall taste of the dish.

Step 5 – Chill and Serve

After the salad has marinated for a short while, it’s ready to be served. For an extra refreshing experience, you can chill the salad in the refrigerator for about 30 minutes before serving. This step is especially enjoyable during hot weather, as the cool, crisp cucumbers provide a delightful contrast to warm dishes.

Serve the Korean cucumber salad as a side dish alongside your favorite Korean meals, such as bulgogi, bibimbap, or grilled meats. It also pairs well with rice, noodles, or even as a standalone snack.

If you have leftovers, store them in an airtight container in the refrigerator. The salad is best enjoyed within 1 to 2 days, as the cucumbers may lose their crunch over time. Before serving leftovers, give the salad a gentle toss to redistribute the seasoning.

Pro Tips for the Perfect Salad

Choosing the Right Cucumbers

Selecting the appropriate type of cucumber is crucial for achieving the desired texture and flavor in your Korean cucumber salad. Here are some options to consider:

  • Korean cucumbers: These are the traditional choice for this salad. They are slender, have thin skin, and a crisp texture. If available, they are the ideal option.
  • English cucumbers: Also known as hothouse cucumbers, they have a mild flavor, thin skin, and minimal seeds, making them a suitable alternative.
  • Persian cucumbers: These small, seedless cucumbers are crisp and flavorful, making them another excellent choice.
  • Kirby cucumbers: Known for their firm texture, they hold up well in salads and are commonly used for pickling.

Avoid using cucumbers with thick skins and large seeds, as they may not provide the desired crunch and can introduce a bitter taste.

Balancing Flavor and Texture

Achieving the perfect balance of flavors and textures is key to a successful Korean cucumber salad. Here are some tips to help you master this dish:

  • Salt the cucumbers: As mentioned earlier, salting the cucumbers draws out excess moisture, preventing the salad from becoming watery and ensuring the cucumbers remain crisp.
  • Adjust the seasoning: Taste the seasoning mix before adding it to the cucumbers, and adjust the ingredients to suit your preferences. If you prefer a spicier salad, add more gochugaru. For a tangier flavor, increase the amount of rice vinegar.
  • Use fresh ingredients: Fresh garlic, green onions, and cucumbers will enhance the overall flavor of the salad.
  • Serve promptly: While the salad can be stored for a short period, it’s best enjoyed fresh to maintain the crisp texture of the cucumbers.

By paying attention to these details, you’ll create a Korean cucumber salad that’s both flavorful and refreshing.

Serving Suggestions and Storage

What to Pair It With?

Korean cucumber salad isn’t just a standalone superstar—it’s a versatile sidekick to a wide range of main dishes. Whether you’re whipping up a full Korean feast or just looking for a crisp, tangy side to balance out a rich entrée, this salad fits right in. Its cool crunch and spicy zing make it the perfect companion to meaty, savory dishes. Here are some great pairings:

  • Korean BBQ (Galbi or Bulgogi): The spiciness and acidity of the cucumber salad cut through the rich, smoky flavors of grilled beef or pork.
  • Bibimbap: This colorful rice bowl benefits from the fresh crunch and spice of the cucumber salad as a topping or side.
  • Grilled Chicken or Fish: The refreshing salad can act as a palate cleanser when served with grilled proteins.
  • Spicy Korean Fried Chicken: It balances the heat and grease of fried dishes with its light and cool profile.
  • Steamed Rice: Sometimes, all you need is this salad and a bowl of fluffy white rice for a satisfying, simple meal.

You can even use it as a filling in wraps or sandwiches, add it to lettuce wraps for extra texture, or serve it as a part of a banchan spread—a selection of Korean side dishes. Its bold flavor makes it an exciting addition to any plate.

How to Store It Right?

While Korean cucumber salad is best enjoyed fresh, it can be stored for later use with the right approach. Here’s how to do it properly:

  • Use an airtight container: This helps retain the flavors and keeps the salad from absorbing other odors in the fridge.
  • Refrigerate immediately: Store it in the fridge as soon as you’re done mixing it to preserve the texture and taste.
  • Consume within 1–2 days: While it might last longer, the cucumbers will start to lose their crunch and become soggy after a day or two.
  • Don’t freeze: Freezing will ruin the texture of the cucumbers and is not recommended.

Before serving the stored salad, give it a gentle stir to re-mix any separated liquid or seasoning. If needed, add a little more sesame oil or a pinch of salt to refresh the flavors.
