Deliciously Easy Korean Cucumber Salad Recipe (Oi Muchim)

Table of Contents
Okay, so the korean cucumber salad recipe. Let me guess, you’re standing in front of your fridge, staring at that sad cucumber that’s about to go soft, thinking, “Is there any way to jazz this up?” Or maybe—something’s whispering for a fresh kick alongside dinner, but you want simple, not complicated. Good news… This dish (which honestly puts some fancy restaurant salads to shame) is a snap. If you love bright, bold flavors like in this quick and tasty easy pasta salad recipe with fresh veggies, Oi Muchim brings a whole new flavor story—right from your own kitchen.
Why this is the best Korean cucumber salad recipe
Now, I’m not exaggerating when I say this korean cucumber salad recipe is a total game-changer. As a person who can mess up boxed mac and cheese (don’t ask), I promise: this one’s almost impossible to mess up… even if you try.
It’s spicy, a bit sweet, and way more exciting than your average salad. What really gets me, though, is the crunch. You want crisp? Use Korean or Persian cucumbers if you can, but honestly—whatever’s in your crisper will work. Salt does its magic and pulls out the extra water, so you get that snap in every bite.
Other recipes sometimes go overboard on the sauce, drowning the poor cukes. Not this one. You’ll actually taste the vegetable! If you like food that gives you a wake-up call (in a good way), this is it.

A friend once called it “addictive and, uh, dangerous.” She wasn’t wrong.
How to make this easy Korean cucumber salad
Alright, real talk: this dish comes together in maybe 10 minutes—and half of that’s just slicing cucumbers and raiding your pantry.
You start by thinly slicing your cucumbers—don’t stress over perfect shapes. Give ’em a sprinkle of salt and let them sit for, say, five minutes. This isn’t some fancy technique—just salted so they stay crisp in the salad. (Don’t skip it tho.)
Rinse the salt off—nobody wants a salt lick for dinner—and squeeze gently. Toss the cucumbers in a bowl with gochugaru (that’s Korean chili flakes), minced garlic, a little soy sauce, splash of rice vinegar, sesame oil, and a pinch of sugar. Give it a good mix with your hands (feels oddly satisfying).
That’s it. You’re pretty much done. If you like it colder, pop it in the fridge. If you’re impatient like me, just eat it right away.
My aunt tells me it tastes best after an hour, but honestly, I can’t wait that long.
Ingredients for Korean cucumber salad

For this classic Oi Muchim, here’s what you want on hand. Most of it’s probably already lurking in your kitchen (except maybe the gochugaru, but a decent Asian market or online store’s got your back):
- 2 large cucumbers (English, Persian, or Korean cucumbers work best)
- 1 tsp salt (for drawing water out)
- 2-3 garlic cloves, minced
- 1½ tablespoon gochugaru (Korean chili flakes)
- 1 tbsp soy sauce
- 1 tbsp rice vinegar
- 1 tsp sugar (you can use honey)
- 2 tsp sesame oil
- 1 tbsp toasted sesame seeds
- Optional: sliced green onions for a little flair
If you have none of these—maybe a neighbor does. Or get creative! That’s what cooking is for, right?
Variations of Oi Muchim
This korean cucumber salad recipe is endlessly riffable, which makes it fun (and not annoying) to make often. I’ve tried tossing in thin-sliced onions, a little grated carrot, or even a few radish slices for extra bite. Folks who don’t do spicy? Just swap the gochugaru for a tiny drizzle of chili oil.
If you want an extra fresh taste, a squeeze of lemon or lime is epic. Oh, and my cousin loves adding shrimp for some extra protein—makes it nearly a full meal. For the vegan crowd (hey, that’s me half the week), skip the fish sauce some traditional recipes use. Honestly, I never miss it.
Want it less vinegary? Just use a touch less rice vinegar. It’s one of those recipes that gives you room to play—no need to measure to the last grain.
“I’ve eaten Oi Muchim all over Seoul, and this homemade version is shockingly close—maybe even better because I get to tweak it how I like,” says Alex L., a home cook who tried this recipe last summer.
Here’s what to serve spicy Korean marinated cucumbers with
This “side dish” (banchan!) just sneaks onto every table. Here’s how you can serve it up to make the whole meal sing:
- With hot steamy rice and grilled meats. BBQ night? It’s dreamy.
- Next to ramen, dumplings, or any noodle dish. That spicy, tangy flavor is the ultimate sidekick.
- Add a scoop to sandwiches or grain bowls! Instantly upgraded.
- Try it with other crisp salads, like a Mediterranean Chopped Salad Recipe if you want more veggie crunch.
This salad’s honestly the MVP at my summer cookouts—it’s always first to disappear.

Common Questions
Do I need Korean chili flakes or can I use regular ones?
You should use gochugaru for that classic flavor. But hey, if you only have regular chili flakes, go easy—they’re way spicier.
Can I make it ahead of time?
Totally. Make it a few hours before serving—it actually soaks up more flavor. Try not to let it sit overnight, though, or it might lose crunch.
Do I peel the cucumbers?
Nope! That skin gives the salad its signature crunch, unless the skin is super thick. Then you might want to take a little off.
Is this salad vegan?
As long as you use soy sauce (not fish sauce), absolutely! Swap honey for sugar if you want 100% plant-based.
How do I stop it turning soggy?
Salting the cucumbers first really helps. Also, eat it sooner, not later—easy fix!
