What is Cucumber Kimchi?

Cucumber kimchi is a delicious Korean side dish, also known as oi kimchi. It’s very similar to korean cucumber salad, or oi muchim. When you think of traditional kimchi, you probably think of a tangy, spicy, and salty fermented side dish.

Comparatively, Korean cucumber kimchi tastes less tangy while still bringing the crunchy texture and salty, spicy flavor. Like kimchi, this recipe uses gochugaru (korean chili flakes) for spice.

But unlike kimchi, this recipe is not fermented. As the internet knows cucumber kimchi, it is a non-fermented, spicy cucumber salad. And trust me, it is delicious. This recipe makes a great side dish, or the perfect snack on a hot summer day.

What to Eat Cucumber Kimchi With

I’ll be honest with you, I eat it plain as a snack. It just doesn’t last for long in my house! But traditionally, it is served as a side dish, or in Korean, banchan. As a general rule of thumb, cucumber kimchi goes great with grilled meats and rice. It goes well with a number of Korean recipes, especially Korean BBQ. But here are some different ways to serve cucumber kimchi:

  • With Korean fried chicken
  • Alongside marinated beef short ribs (Galbi)
  • With stir-fried noodles
  • As a side to beef bulgogi
  • With plain rice and a fried egg
  • Alongside ramen
  • With fried rice, or your favorite rice bowl
  • As a side to korean stews (Jjigae)

But, there are no rules here! You can get creative with it, and experiment with your favorite main dishes.

What is Gochugaru?

Gochugaru is a type of Korean red pepper flakes that are used in traditional cucumber kimchi. Known for its mild to moderate heat level, gochugaru is slightly sweet and smoky. It serves as the foundation of the flavor profile for many dishes in Korean cuisine.

You can either buy gochugaru powder or gochugaru flakes. The powder is used for making homemade gochujang. For making kimchi or kimchi paste, the flakes are preferred.

Gochugaru Flakes vs. Red Chili Flakes

How does gochugaru compare to regular red chili flakes? Gochugaru has more depth of flavor and smokiness, a deeper color, and is slightly less spicy. It also has more of a flaky texture, and incorporates into the salad better than regular red chili flakes.

In a pinch, you can grind up some red chili flakes that you have on hand, and add smoked paprika to taste. But for the full effect, gochugaru will give you the best result!

FAQ’s about Cucumber Kimchi

Can cucumber kimchi go bad?

Yes, just like any perishable food, it can go bad. Store leftover cucumber kimchi in the fridge in an airtight container to make it last longer.

It can last for up to a week, depending on the freshness of ingredients used. But it is best eaten within the first 2-3 days.

What is cucumber kimchi?

Cucumber kimchi is a popular korean side dish. In Korean, it is called oi kimchi, and it is typically served with rice and grilled meats.

What does cucumber kimchi taste like?

The taste can vary based on the recipe used. Most commonly, it is garlicky, spicy, salty, and slightly sweet. Using crisp cucumbers gives a pleasantly crunchy texture.

Is cucumber kimchi healthy?

Yes! Of course, different people will have unique nutritional needs. But in my book, it’s a healthy cucumber salad. The fiber in this side salad feeds good bacteria in your gut! It contains both carbs and fats, but for a more balanced meal, it’s best paired with a source of protein. It is a side dish, after all.

Is cucumber kimchi fermented?

No, it is typically not fermented. It’s called ‘kimchi’ because it uses many of the traditional ingredients, like chili pepper flakes and garlic, and follows a similar preparation method. The fermentation process uses salt to create an environment where lactic acid bacteria thrive. So you’ll want to follow a recipe specific to fermentation to get the right amount of salt.

Some cucumber varieties, especially larger ones, can be more bitter. Try using Persian cucumbers for a milder taste. Cucumber seeds can also contribute to bitterness, so removing them can help reduce both bitterness and lectin content. Lastly, older or overripe cucumbers tend to be more bitter, so be sure to use fresh, firm cucumbers for the best flavor.

Yes, you can! You can substitute gochujang paste, red chili flakes mixed with smoked paprika, cayenne pepper mixed with smoked paprika, or even ancho chili powder in a pinch.

Notes

Substitutions: If you are out of rice vinegar, you can use apple cider vinegar, but use a little less since it has a stronger flavor.

Fridge life: Since this is a dressed salad, it tastes best fresh. I recommend eating this salad within the first day or two, but it can last in the fridge for up to a week.

Customizations: You know your taste buds better than anyone else, feel free to adjust the seasonings as needed! If you are sensitive to spice, start with half the amount of gochugaru. If you have a sweet tooth, up the sugar.
