Ingredients You Need

Here is what you need for a classic Korean cucumber salad, also called oi muchim:

Cucumbers
- 2 long English cucumbers or 4–5 small Persian cucumbers
- These stay crisp and have thin skin, so you skip peeling.
- If you only have regular slicing cucumbers, peel them, scoop out the seeds, and slice them a bit thicker.
Salt
- 1 to 1½ teaspoons kosher salt
- You use this to draw out extra water from the cucumbers and season them.
- Use less if you use fine table salt, since it tastes saltier.
Garlic
- 2–3 cloves fresh garlic, minced very fine
- Jarred minced garlic works in a pinch, but fresh garlic gives sharper flavor.
Green onion
- 2 green onions, thinly sliced
- You can swap in a little finely sliced red onion if needed, but green onion tastes more traditional.
Gochugaru (Korean red pepper flakes)
- 1 to 2 tablespoons gochugaru
- This ingredient gives the salad its signature color and gentle smoky heat.
- Do not swap it with Italian red pepper flakes, since those taste much hotter and sharper.
- If you cannot find gochugaru, use a mix of sweet paprika and a tiny pinch of chili flakes, and expect a different flavor.
Soy sauce
- 1 tablespoon soy sauce
- Use regular or low sodium, and adjust salt to taste.
- For gluten free, use tamari.
Rice vinegar
- 1½ to 2 tablespoons unseasoned rice vinegar
- Seasoned rice vinegar already contains sugar and salt, so reduce the sugar and salt a bit if you use it.
Sugar
- 1 to 2 teaspoons granulated sugar or honey
- This balances the heat and acidity without making the salad taste dessert-like.
Sesame oil
- 1 tablespoon toasted sesame oil
- This adds nutty aroma and that classic Korean side dish vibe.
- Use a Korean or Japanese brand if possible, since those usually taste richer.
Sesame seeds
- 1 to 2 teaspoons toasted sesame seeds
- White or a mix of white and black both work.
- You can toast raw seeds in a dry skillet over low heat for a few minutes until fragrant.
Optional add-ins
- A small carrot, cut into thin matchsticks, for extra crunch and color
- A few strips of red bell pepper for sweetness
- A tiny drizzle of fish sauce for deeper umami, if you enjoy that flavor

Equipment list

You do not need fancy gear for this salad, just:

Sharp chef’s knife or mandoline for thin, even slices
Cutting board
Medium mixing bowl for salting cucumbers
Large mixing bowl for tossing the salad
Colander or fine mesh strainer
Tongs or clean hands for mixing

Tips & Mistakes

Slice cucumbers evenly so they soften at the same rate and keep a nice crunch.
Salt the cucumbers long enough to pull out water, about 10 to 15 minutes, so the salad does not turn watery.
Do not skip rinsing off extra salt, or the salad may taste too salty and harsh.
Squeeze the cucumbers gently after rinsing, since hard squeezing can crush them and make them limp.
Taste the dressing before you add cucumbers, then adjust heat, sweetness, and acidity to your preference.
Use gochugaru, not regular chili flakes, since regular flakes can overpower the salad and burn your mouth.
Add sesame oil at the end and do not cook it, since heat can dull its nutty flavor.
Chill the salad for at least 10 minutes if you have time, so the flavors settle and the cucumbers soak up the seasoning.
Eat the salad within a day or two, because the cucumbers soften more each day in the fridge.
Stir gently before serving, since the dressing can settle at the bottom of the bowl.

How to Make Easy Korean Cucumber Salad Recipe

Step 1: Slice and salt the cucumbers

Wash the cucumbers and pat them dry. Slice them into thin rounds, about ⅛ to ¼ inch thick, and place them in a medium bowl. Sprinkle the salt over the slices and toss well so every piece gets a little salt.

Let the cucumbers sit for 10 to 15 minutes at room temperature. They will release a good amount of water and soften slightly while they stay crisp in the center.

Step 2: Rinse and squeeze

Pour the cucumbers into a colander and rinse quickly under cold water to remove extra salt. Taste one slice to check the salt level, and rinse again if it tastes too salty. Gently squeeze small handfuls of cucumber over the sink to press out excess water, then place them in a large mixing bowl.

Do not crush them into a pulp, since you want them to keep some structure. Set the bowl aside while you mix the seasoning.

Step 3: Mix the seasoning sauce

In a small bowl, combine minced garlic, sliced green onion, gochugaru, soy sauce, rice vinegar, sugar, and sesame oil. Stir until the sugar dissolves and the mixture looks uniform and glossy. Taste the sauce and adjust it: add more sugar for sweetness, more vinegar for tang, or more gochugaru for heat.

If you use fish sauce, add a small splash now and stir again. The sauce should taste slightly stronger than you like, because the cucumbers will dilute it a bit.

Step 4: Toss everything together

Pour the seasoning sauce over the cucumbers in the large bowl. Add sesame seeds and any optional vegetables like carrot matchsticks or bell pepper strips. Toss gently with tongs or clean hands until every cucumber slice looks coated with the red seasoning.

Taste again and tweak the flavor if needed. Add a pinch of salt, a little more vinegar, or a sprinkle of sugar until it hits your sweet spot.

Step 5: Chill briefly and serve

You can serve the salad right away, and it will taste fresh and crunchy. If you have time, cover the bowl and chill it in the fridge for 10 to 20 minutes. The cucumbers will soak up more flavor and the garlic will mellow a bit.

Give the salad a quick stir before serving, then sprinkle a few extra sesame seeds on top for a nice finish. I also like to add a few extra green onion slices for color.

Variations I've Tried

I sometimes add thinly sliced radish for extra peppery crunch, which pairs nicely with the spicy dressing. A handful of shredded carrot adds sweetness and color, and kids usually go for that version. When I want more protein, I toss in some cubed firm tofu that I pat dry first, so it soaks up the dressing.

I also enjoy a less spicy version with half the gochugaru and a little extra sugar, which works well for spice-sensitive friends. On hot days, I add a spoonful of grated ginger to the dressing for a bright, cooling kick that wakes up the whole bowl.

How to Serve Easy Korean Cucumber Salad Recipe

Serve this Easy Korean Cucumber Salad Recipe as a banchan side dish with steamed rice and grilled meat, or next to a simple pan of sautéed chicken or tofu. It also tastes great tucked into a rice bowl with fried eggs, kimchi, and some roasted vegetables. I like to pile it on top of cold noodles or ramen for a crunchy, spicy contrast.

You can also bring it to potlucks or picnics as a fresh, bold alternative to heavy mayo salads. Just keep it chilled in a cooler, and stir it again before everyone digs in.

How to store

Fridge: Store leftovers in an airtight container in the refrigerator for up to 2 days; the cucumbers will soften more each day but still taste good.
Freezer: Skip freezing this salad, since cucumbers turn mushy and watery after thawing.
Best serving method from fridge: Serve it cold straight from the fridge, or let it sit at room temperature for 5 to 10 minutes to take off the chill.
Reheating: Do not reheat this salad, since heat will wilt the cucumbers; treat it as a cold or cool side dish only.
