    If you're looking to serve something light and refreshing at a bbq, then this Korean cucumber salad is the one. Not only is it super easy to make, but the sweet tanginess and refreshing crunch also go very well with any type of grilled meat.

    Keep in mind that cucumbers are very watery, so if you do plan to take this cucumber salad to a party or event, there are a few extra steps required if you plan to make it ahead of time to prevent a lot of waterlogging.

    That being said, when I am looking to make a quick vegetable side, at home without much fuss, I will also make this to go with my lunches or dinners so this salad is pretty much great all year round.

    What is Korean Cucumber Salad (Oi Muchim)?

    Oi muchim (Korean Cucumber Salad) is a cucumber salad made with cucumbers, gochugaru, soy sauce, rice vinegar, sugar, garlic, and toasted sesame seed oil.

    Similar to sunomono which is a Japanese cucumber salad that doesn't have any spiciness or chili flakes in it, Korean cucumber salad is light and refreshing with a sweet and tangy flavor with a bit of spiciness from the gochugaru (Korean chili flakes).

    There are many versions of oi muchim recipes out there and some have gochujang in them. This cucumber salad is made without gochujang because I like it less spicy and more light.

    What Kind of Cucumbers To Use

    For the best tasting Cucumber salad, I like to use seedless cucumbers or cucumbers without a lot of seeds like the mini cucumbers or English\Persian cucumbers (which are almost the same thing).

    Try to avoid field cucumbers, they usually have a dark green thick skin and have very large seeds in the middle. That being said, you can still use them, but if you do, use a spoon to scrape out all the seeds and peel the cucumber before using it.

    Ingredients for Korean Cucumber Salad

    Ingredients for Korean cucumber salad (cucumber, gochugaru, green onion, soy sauce, sesame oil, toasted sesame seeds, sugar, rice vinegar and garlic)
    • Cucumber - For the best tasting Korean cucumber salad, my first choice of cucumber to use are mini cucumbers, then English\Persian cucumbers. Try to avoid using field cucumbers (the dark green thick-skinned cucumbers).
    • Green Onions - Raw onions can be very strong and spicy in salads, especially if you don't draw out the moisture with salt or soak them in water/acid for a long period of time. For this reason, I only use green onions/scallions in this salad. Green onions are much milder and still give that great oniony flavor without overpowering the salad.
    • Gochugaru (Korean chili flakes) - I only use gochugaru and do not use any gochujang in this cucumber salad because I wanted to keep it lighter and less spicy.
    • Soy Sauce/Sugar/Sesame Oil - These 3 ingredients are also a must for the cucumber salad dressing. You can substitute soy sauce with fish sauce but other than that I wouldn't change this trio.
    • Rice Vinegar - I like to use rice vinegar for the dressing because it is a milder vinegar, but if you don't have it you can substitute it with white vinegar.
    • Sesame Seeds - Sesame seeds must be toasted to get the best flavor for the salad. If you want to skip toasting it, you can buy the pre-toasted at Korean supermarkets.
    • Garlic - You definitely don't want to skip adding the garlic as it is the star of the recipe and brings the whole recipe together.

    How to Make Korean Cucumber Salad

    Preparation

    1. Cut both tips off the ends of the cucumbers and discard them.
    2. [English Cucumbers] Cut the cucumber in half length-wise and slice the cucumbers into ⅛-inch slices. They should look like thin half-moons.
    3. [Mini Cucumbers] Slice the cucumbers into ⅛-inch slices. They should look like round circles.
    4. Grate or finely mince the garlic and set it aside.
    5. Finely slice the green onions (including the whites, but discard the tips with the roots) and set them aside.
    6. Toast the sesame seeds until they are golden brown (unless you bought them pre-toasted) and set them aside to cool.

    Make the Korean Cucumber Dressing

    1. In a small bowl, mix together the gochugaru (Korean chili flakes), soy sauce, rice vinegar, sugar, toasted sesame oil, and garlic.

    Mix Everything Together

    1. In a larger bowl, mix together the cucumber, green onions, toasted sesame seeds, and the dressing until every cucumber slice is coated with the sauce.
    2. Serve immediately, or let it sit and marinate for 5-10 minutes before digging in!

    Tips

    • If you use cucumbers with a lot of seeds like garden or field cucumbers (the dark green cucumbers with thick skin), remove the seeds by scraping them out with a spoon before using them to prevent them from being waterlogged.
    • If you find your cucumber skins are very tough, you can also peel it the skins off but any low-seed cucumbers will have a nicer crunch to them if you keep the skins on.
    • Once the dressing draws out the water from the cucumbers, the extra sauce is delicious on plain white rice.

    Can I Make it Ahead of Time?

    Yes, you can make this ahead of time but it will require some extra steps to prevent it from being waterlogged.

    1. You will need to remove the seeds from the cucumber which has extra water in it. Use a spoon to scrape it out before slicing the cucumber.
    2. Sprinkle salt on the cut cucumbers for 15 minutes to draw out more of the water from the cucumber. Rinse off the salt and dry the cucumbers with a towel.
    3. Premake the dressing (add the green onions and sesame seeds in with the dressing) but don't put it on until you are ready to serve it.
    4. When you are ready to make it or bring it to an event, mix in the dressing and store it in a well-sealed container. With the excess moisture removed from the cucumber, it will last for 1 day in the fridge. It may still contain some excess water, but we removed it as much as we could.

    FAQs

    How Long Can I Store This?

    You can store Korean cucumber salad for 1-2 days but it is best eaten fresh because the salt will draw water will come out of the cucumber and make it watery the next day.

    If your cucumber salad becomes water the next day, you can make it flavorful again by mixing 1 teaspoon of gochujang into it.

    How Do You Make This Cucumber Salad Not Spicy?

    To make this Korean cucumber salad not spicy, put in a little less gochugaru than what is called for in the recipe.
