Spicy & Crunchy Korean Cucumber Salad (Oi Muchim)

If you've ever been to a Korean BBQ restaurant, you know that the side dishes (banchan) absolutely steal the show. My personal favorite has always been the cucumber salad, known as Oi Muchim. It hits literally every flavor profile you could ever want—it's incredibly savory, a little sweet, perfectly tangy, and has just the right amount of kick.

The best part about this recipe? It takes under 10 minutes to make from start to finish. There's no cooking required, making it the absolute perfect side dish for a hot summer day, a busy weeknight dinner, or your next backyard barbecue. For maximum crunch, I highly recommend using Persian or English cucumbers, as they have thinner skins and fewer seeds than standard slicing cucumbers!

What You'll Need

The Vegetables:

  • English or Persian Cucumbers: 1 large English cucumber or 4-5 mini Persian cucumbers, thinly sliced into rounds.

  • Green Onions (Scallions): 2 stalks, finely chopped (both the green and white parts).

The Spicy & Tangy Dressing:

  • Gochugaru (Korean Red Pepper Flakes): 1 to 2 tablespoons, depending on your spice tolerance. (Do not substitute with standard Western chili flakes; they are too spicy and lack the smoky sweetness!)

  • Rice Vinegar: 2 tablespoons for that essential zesty tang.

  • Soy Sauce: 1 tablespoon for savory umami flavor.

  • Toasted Sesame Oil: 1 tablespoon to give it a rich, nutty finish.

  • Sugar (or Honey): 1 teaspoon to balance out the heat and the acid.

  • Fresh Garlic: 2 cloves, minced.

  • Toasted Sesame Seeds: 1 tablespoon for extra crunch and presentation.

  • Salt: Just a pinch, to taste.

How to Make It

  1. Prep the Cucumbers: Wash your cucumbers thoroughly and slice them into thin rounds (about 1/8 to 1/4 inch thick). Place the sliced cucumbers into a large mixing bowl.

  2. Mix the Dressing Ingredients: Right on top of the cucumbers, add your minced garlic, chopped green onions, Gochugaru, rice vinegar, soy sauce, sesame oil, sugar, and toasted sesame seeds.

  3. Toss Gently: Using a spoon or clean hands (gloves are recommended if you are mixing by hand so the chili doesn't burn your skin!), gently toss everything together until every single cucumber slice is beautifully coated in the red dressing.

  4. Taste and Adjust: Give a cucumber slice a taste. Want it sweeter? Add a pinch more sugar. Need it saltier? Add a tiny splash of soy sauce or a pinch of salt.

  5. Serve: You can serve this immediately for the ultimate fresh crunch! If you prefer softer cucumbers with a more marinated flavor, cover the bowl and pop it in the fridge for about 15–30 minutes before serving.
