Spicy Korean marinated cucumbers! (Oi Muchim!) We LOVE to keep these handy in the fridge. This Korean pickled cucumber salad is best served with your favorite meats and vegetables (my choice is Hanger Steak in Lettuce Wraps! Soaked and salted cucumbers are tossed with gochugaru and vinegar. They taste SO good and the perfect crunch and the perfect side dish.

What are Korean pickles?

These marinated cucumbers (also can be called cucumber kimchi and Oi Muchim) are an extremely popular Korean side dish (type of cucumber pickles), also called Banchan. Banchan means “side dish” in Korean, traditionally there are many different Banchan served in traditional Korean food like cabbage kimchi, pickled radishes and more!

Whenever I’m eating at a Korean bbq restaurant, I will always re-order the cucumber kimchi – the perfect bite and refreshing crunch, and the most delicious recipe. Additionally, sometimes I’ll even just have over rice with a fried egg/soft boiled egg and some seaweed, delicious!

Ingredients you need for your spicy Korean cucumber salad

  • Persian cucumbers: Kirby cucumbers and English cucumbers will do, but I definitely prefer Persian or Japanese cucumbers for this!
  • kosher salt
  • scallions/green onions
  • clove of garlic
  • *Gochugaru (Korean chili flakes, Korean red pepper flakes) or red pepper chili powder, chili flakes work too
  • sesame seeds
  • rice vinegar
  • sugar
  • sesame oil
  • Fish sauce and soy sauce (optional) we are omitting in this recipe, but feel free to add a few dashes to the pickling mixture if you prefer!

What is Gochugaru?

Gochugaru is a Korean red pepper flake. I recommend the finer flakes for this recipe, but you can use course if you prefer. If you can’t access these flakes, red pepper/chili flakes work as well.
