This Korean Cucumber Salad (oi muchim) recipe is so delicious! Spicy, crunchy, and full of flavor it is an Asian Cucumber Salad made with gochugaru, which is Korean red pepper flakes. It's quick to make and comes together in just a few minutes. Perfect to serve when entertaining, or great as a side or I love it as a snack!
This is my favorite Korean side dish. I tried it for the first time at Korean bbq in Seol, Korea and fell in love and knew I had to figure out how to make it at home. I tested this recipe over and over to try to get it as close as I could to what I ate in Korea.
This would go great as a side to our Asian Chopped Salad Chicken Wrap or even our Gluten Free Orange Chicken. We love to serve it when we're having fried rice, bibimbap, Korean bbq or bulgogi.

Ingredients
Below is a list of ingredients needed for this recipe. Follow our tips on each ingredient for best results.
- cucumbers - cucumbers are the highlight of this dish! I used an English cucumber. Other types of cucumber also work great, just make sure they are a variety without a lot of seeds or they will get mushy.
- soy sauce - soy sauce it used to add a little flavor and saltiness.
- rice vinegar - the rice vinegar adds the tanginess and is the main liquid for this sauce.
- gochugaru - the star of the show and adds the spice! It also adds a hint of smokiness and a slight hint of sweetness. There isn't a great substitution for gochugaru other than gochujang. See the "substitution" section below for some ideas.
- sugar - just a touch of sugar, gives it that added sweetness for that spicy/ slightly sweet flavor and really accents the other ingredients. When testing this recipe, I tried it without sugar and it wasn't the same. It definitely needs that subtle sweetness.
- minced garlic - the minced garlic adds a lot of flavor and pulls it all together for the perfect taste.
- green onions - for garnishing and add a little flavor and texture.
- sesame seeds - the sesame seeds also add a finishing flavor and texture wrapping it all up into one delicious dish.

How to Make Korean Cucumber Salad
Use these process shots to help get the results you are wanting. The pictures can help with texture and be a visual guide for best results.
1. Slice cucumbers into ⅛" slices. If making the "make ahead" version, place cucumbers in a sieve. Sprinkle 1 teaspoon salt over top and let sit for 30 minutes. Rinse with water then blot off the water with a tea towel or similar.
2. Pour the soy sauce, rice vinegar, sugar and minced garlic over the sliced cucumbers in a bowl. OR place in a small, separate bowl.
3. Pour the gochugaru over top and mix until well combined. OR add the gochugaru to the small bowl of spices and whisk together to combine. Then pour over the cucumbers and toss to combine.
4. Sprinkle green onions and sesame seeds over the top and serve!
Hint: If you're in a hurry, you don't have to mix the ingredients together in a bowl first. You can simply measure them over the cucumber and give it a good stir.
Substitutions
We love switching things up when we're in the kitchen. Try any of these variations and substitutions for something a little different.
- Cucumbers - you can use any type of cucumber desired, you just want about 250 - 300g of cucumber. You can use Persian, cucumber, pickling and more!
- Gochugaru - There isn't a good substitute for gochugaru, other than gochujang, which is gochugaru in paste form. If needed, you can use red pepper flakes instead. It isn't a great subsitute and you'll need a lot less. Start with ½ teaspoon then add to taste. While not a great substitute, it will still taste delicious. You can also try mixing some cayenne pepper with smoked paprika for a similar taste.
- Black Sesame Seeds - use black sesame seeds instead of white for a stronger sesame taste and a few more antioxidants.
- Sugar Free - make this sugar free by skipping the sugar. You'll miss that hint of sweetness that goes in its flavor profile, but it is still delicious.
Learn From Us
One time when testing this recipe, I made it around lunch time with the intent to serve it with dinner. I ate some with my lunch (every time I make it I have to make extra so I can snack on it, lol) and it was perfect. Dinner time rolled around and it was totally mushy. I did more research and figured out how to keep the cucumbers crunchy longer! See the "make ahead" below or in the recipe card.
Storing Cucumber Salad
Store in an airtight container in the refrigerator for up to 2 days. We recommend eating this fresh, but if storing or serving later, we recommend following our "make ahead" directions to keep the cucumbers from getting mushy.
Make Ahead
After slicing the cucumber, place in sieve or strainer and pour 1 teaspoon salt over top and let sit for 30 minutes. Rinse with water, then squeeze out any excess water. Finish the recipe as directed. This will keep the cucumbers crunchy.
