An Easy Spicy Cucumber Salad

I’m a huge fan of quick pickling and tangy, fermented flavors – and this Quick Cucumber Kimchi is my latest obsession. Instead of the napa cabbage used in my quick kimchi recipe, cucumbers are the stars in this easy, spicy cucumber salad.

Eaten as both a condiment and a side dish, this kimchi variation is downright addictive. So I’m happy to know that it’s also good for you. Kimchi is full of probiotics, which means it’s great for your gut…plus it’s low in calories!

What is Kimchi?

Traditional kimchi is a Korean side made with fermented napa cabbage, Korean chili flakes, ginger, garlic, soy sauce, fish sauce, and other veggies. It often makes an appearance as a side dish on Korean tables – and is absolutely wonderful in kimchi fried rice!

Cucumber kimchi is a variation of the traditional recipe but is still very authentic. This is a quick cucumber kimchi, which doesn’t rely on a long fermentation process – so it’s technically a simple spicy cucumber salad.

Either way, it’s incredibly delicious and adds a tangy crunch to your plate!

What You’ll Need

Quick cucumber kimchi requires a couple items you might not already have in your pantry, but you can easily find them online or at most grocery stores’ Asian section.

  • Persian cucumbers – Persian cucumbers, or Lebanese cucumbers, are like a smaller version of English cucumbers. They have a thin skin and fewer, softer seeds. If you can’t find Persian cucumbers, English cucumbers are a fine substitute.
  • Salt – Kosher salt helps brine the cucumbers and gives them a bit of salty flavor.
  • Granulated sugar – Granulated sugar brings out the natural sweetness in the cucumbers.
  • Gochugaru – Gochugaru is Korean chili flakes– it adds a bit of spice and smoky flavor to the cucumber kimchi. I’m using Mother In Law’s brand but there are plenty of options online and in grocery stores.
  • Rice vinegar – Rice vinegar adds a bit of acidity to the kimchi and helps bring out the sweetness in the cucumbers.
  • Soy sauce – Soy sauce adds saltiness and umami flavor.
  • Sesame oil – Sesame oil adds a rich nutty flavor. I highly recommend using toasted sesame oil rather than regular sesame oil.
  • Fish sauce – Fish sauce adds that bit of funkiness that’s found in the traditional fermented flavor of kimchi. I really like this fish sauce.
  • Garlic – Garlic adds an earthy bite to the kimchi that pairs deliciously with cucumber and soy.
  • White onion – Onion is optional in this kimchi but it adds additional earthiness and allium flavor. I personally love cucumber kimchi with the added onion!

Basically, cucumber kimchi can be added to anything that needs a pop of fresh and tangy, slightly spicy flavor. Though I’m guilty of eating it straight from the jar myself!

How Long Will This Last?

Cucumber kimchi will keep well in the fridge for about a week. Just be sure to store it in a sealed, airtight container. (Mason jars are perfect!) Note that the cucumbers will continue to release moisture and can eventually become softer, which is why I recommend keeping this for just a week despite the fermentation. I definitely like this best while the cucumbers are still crunchy!
