What Is Korean Cucumber Salad Made Of?
Traditional Korean cucumber salad is made of cucumbers, green onions, garlic, and sesame oil. It is a straightforward side dish that allows you to use any kind of crunchy cucumber. The most common one used to make the dish is the crunchy Korean Oi (‘cucumber’ in Hangul). However, other versions, such as Kirby, Persian, Japanese, and English cucumbers, would make a delicious substitute.

The side dish is often seasoned with a host of seasonings. Among them are vinegar, soy sauce, sugar, salt, sesame seeds, and chilli powder or chilli flakes. Heavier seasoned Oi Muchim pairs well with rich meals such as Korean barbecue. On the other hand, the lighter seasoned version is more suitable for lighter meals such as noodles and rice.
The traditional Oi Muchim is often served spicy with the incorporation of chilli powder or chilli flakes. Local cooks typically use their trusty Gochugaru and Gochujang for this. But if your palate is not used to the spice prevalent in most Korean dishes, you can opt-out of the chilli powder and flakes. No worries, our version of Korean cucumber salad is not spicy!
What Does Korean Cucumber Salad Taste Like?

Korean Cucumber Salad Calories
This flavourful dish packs 60 calories per serving, making it one of the healthiest things you can eat. It also makes a great Korean snack if you’re looking for a healthy alternative to your usual chips.
Oi Muchim Ingredients (Non-Spicy)
The ingredients required to make this non-spicy vegan Korean cucumber salad are:
- Cucumbers
- Green onions
- Sesame oil
- Rice vinegar
- Soy sauce
- Sesame seeds
- Salt
- Sugar
Any kind of cucumber will work for this dish. However, try to get your hands on Korean Oi for an authentic, crunchy Korean cucumber salad. They are light-coloured, slender, and have bumps on their thin skin. You can find them at an Asian supermarket. Avoid getting cucumbers that contain a lot of seeds because it may result in your Oi Muchim being soggy.

Any type of sesame oil would work, but we recommend getting Korean sesame oil. It has a slightly different taste and aroma as compared to Chinese sesame oil. It is also lighter in colour and flavour, making it highly appropriate for salads.
We recommend using rice vinegar to maintain the authenticity of the recipe. However, you may also go for distilled or white vinegar as a substitute. We use rice vinegar as it is slightly sweet and less tangy compared to white vinegar. White vinegar is more acidic, so it has a harsher flavour.
Soy sauce will add extra flavouring, especially when you're making a non-spicy version of the salad. You can also substitute soy sauce with coconut aminos or tamari sauce.
Apart from seasoning, salt and sugar are required to draw out moisture from the cucumbers. This will make your vegetables crunchier!
Additional Steps For Smashed Korean Cucumber Salad
Smashing cucumbers is a classic Chinese technique. The process helps crack the skin, release the seeds, and split the flesh into appealing, craggy pieces. Moreover, it also increases the surface area, so more seasoning is absorbed into the green vegetables. A Korean crushed cucumber salad will need some marination time to absorb all the flavours.
For preparing a smashed Korean cucumber salad, you can do it in two different ways:
Method 1: Using a whole uncut cucumber
The cucumber is smashed as a whole and later cut into small pieces. To do so:
- Place the cucumber on a flat surface and pound it with the flat side of a big knife. Alternatively, you can use any flat object like a meat pounder.
- Then, cut into small pieces of 1 to 1 ½ inches.
Pro tip: Wrap the vegetable in a plastic bag. This can avoid splatters and keep your workspace clean.
Method 2: Pre-cut the cucumbers before smashing
Most cucumbers can be pretty thick, especially the Japanese ones. This can make smacking them whole quite tricky. Hence, using this method, they are pre-cut before smashing.
Via this method,
- You can cut the cucumber into two halves and later slice it into pieces. Alternatively, you can also cut them into long pieces of about 1½ to 2 inches beforehand.
- After cutting, place it cut-side down on a flat surface and smash it.
- Repeat until each piece is smashed and transfer them to a bowl.

How To Make Korean Cucumber Salad Spicy
To make it spicy, you will need to add some spice seasoning to the Korean cucumber salad. Here are some ingredients that you can use to make your salad spicy:
Chilli flakes
The easiest method of making any of your food spicy is to sprinkle some chilli flakes over it. And this also applies to Oi Muchim! Just like how you would sprinkle chilli flakes on your pasta or pizza, simply do the same for your salad.
Gochujang
Gochujang is a paste that is very common in Korean cuisine. It is used in many K-foods, including the famous Tteokbeokki. Traditional food makers prepare Gochujang from red chilli peppers, rice, fermented soya beans, and salt. You can adjust the level of spiciness depending on the amount of chilli paste you incorporate into your salad.

Gochugaru
Gochugaru is a chilli powder that is pretty similar to chilli flakes. The powder is coarsely ground and made from deseeded sun-dried peppers.

While Gochugaru is hot, it does have some sweet and smoky flavour notes. The spiciness level will also depend on the method used to dry the peppers. The heat level of Gochugaru lies between 1500 and 10,000 Scoville units.
To prepare the spicy Korean cucumber salad recipe, just add a teaspoon of Gochujang to your salad. Similar to Gochugaru, you can also adjust the level of spiciness by increasing or decreasing the amount you use.
Paprika and Cayenne pepper
There is no other spice that can imitate the flavour of Gochugaru. However, if you don't have Korean chilli paste or flakes, go for paprika and cayenne pepper! Mixing paprika with cayenne pepper can be an excellent substitute for Gochugaru.
Other spices
Apart from the ingredients above, you can use any other kind of substitute that you like. You can use other spices such as Aleppo chilli flakes and chipotle powder.
Oi Muchim may seem very similar to Oi Kimchi, which is Cucumber Kimchi. However, the two are very different from one another. For one, kimchi is a fermented pickled dish. Oi Kimchi is a dish which incorporates many other vegetables, such as carrots, radishes, and cabbage. And, of course, the kimchi sauce makes all the difference.

How To Make Keto Korean Cucumber Salad
To make a keto Korean cucumber salad, you need to cut down on the sugar. However, if you still need some sweet flavouring, you can use one of the sweeteners mentioned below. They are low-carb sugars that will give you sweetness without calories.
- Sucralose
- Stevia
- Xylitol
- Erythritol
- Yacon syrup
- Monk Fruit Sweetener
How Long Does A Korean Cucumber Salad Last?
It typically lasts for about four days. If you're planning to store it for longer, the salad needs to be refrigerated in an air-tight container.

Korean Cucumber Salad Recipe (Not Spicy)
Ingredients
- 1 sliced cucumber (cut into slices 1 or 1 ½ inches)
- 3-4 pcs chopped green onions
- 1 tablespoon sesame oil
- 2 tbsps vinegar
- 1 tablespoon soy sauce
- 1 tablespoon sugar
- ¼ tablespoon sesame seeds
- 1 pinch salt
Instructions
- Slice the cucumber into thin slices and place them in a bowl. Each slice should be around 1 to 1 ½ inch.
- Add the soy sauce, vinegar, and sugar in a separate bowl. Mix well before pouring the soy vinegar into the bowl of cucumbers.
- Then, add ½ teaspoon of sesame seeds, a tablespoon of sesame oil, and chopped onions. Mix the ingredients and taste. You may add salt for more seasoning.
- Serve immediately for a fresh salad. Alternatively, let it sit for about 10-15 minutes before serving for the vegetables to absorb the dressing. You may also refrigerate it for 30 minutes before serving it for a cold Korean cucumber salad.
Notes
- The recipe shared here emulates the non-spicy version, which is suitable for those who do not enjoy spicy foods. If you prefer it spicier, you may add some Gochugaru or chilli flakes. If you do not have any gochugaru, you can also substitute it with gochujang. You can use the same amount of the red pepper paste as a substitute. Please note that gochujang may add a more earthy flavour to your final dish.
- You can add chopped or minced garlic for extra flavour. Adding garlic gives it an extra sharp taste, which some folks may like.
- Although the traditional dish uses sliced cucumbers, you could try smashing them for extra texture. For a crushed Korean cucumber salad recipe, refer to the additional smashing methods in the above sections.
- You can refrigerate the salad for a couple of days and serve it cold. Then, simply freshen it up with freshly chopped green onions and sesame seeds.
