A Note from CJ
I love Korean sides (banchan)!

One of my favorite things about Korean cuisine is the banchan (side dishes) – that’s why I have so many recipes for them! I love Korean Bean Sprout Salad, Korean Braised Tofu, Korean Spinach Side Dish (or Spicy Korean Spinach Side Dish), Korean Braised Potatoes, Korean Stir Fried Fish Cakes and Korean Egg Roll!
Serve them with popular Korean BBQ dishes like Korean Short Ribs (LA Galbi), Beef Bulgogi, or Spicy Pork Bulgogi!

Ingredient Tips
Refer to the recipe card for the full list of ingredients and measurements!
- cucumbers: I recommend using a seedless cucumber like English or Persian cucumbers. If you can’t find a seedless cucumber, cut your cucumber lengthwise and before you begin slicing, scrape out the seeds in the middle with a spoon. I like slicing the cucumbers into 1/8″ thin discs (2-3mm) because they’re thin enough to soak up the dressing, while being thick enough to stay crunchy. Cut them to whatever thickness or even shape you prefer, like half moons, thicker round slices, or 2″ thin diagonal slices.
- gochugaru: Gochugaru is Korean red chili pepper flakes that are vibrant in color, smoky in flavor, and definitely on the spicy side. Adjust the amount used based on your own spice tolerance level.
How to Make Korean Cucumber Salad (Oi Muchim)
Slice, Salt, Drain, and Dry Cucumbers – Slice ends off of your cucumber then thinly slice them into 2-3 mm disks (I recommend carefully using a mandolin for even cuts). Add the cucumbers to a bowl, then mix together with salt and let them rest for 10 minutes. Drain out the excess water and taste for seasoning. If too salty for your tastes, rinse and pat them dry with a paper towel before continuing to step 3.
Marinate Cucumbers for 10 Minutes – In the same bowl with the drained and dried cucumbers, combine with soy sauce, gochugaru, sugar, sesame seeds, onion, scallion, grated garlic, and sesame oil. Mix the cucumbers and seasonings until well combined and the cucumbers turn a deep red color. Marinate the cucumbers for 10 minutes in the dressing before serving and enjoy!

PRO TIPS
CJ’s Recipe & Storage Tips
Remove excess moisture from the cucumbers so they stay crisp – otherwise your Korean Cucumber Salad will turn soggy and watery! Salting for 10 minutes and draining the cucumbers will make a huge difference in the end result! Make sure to taste the cucumbers after draining to see if they’re salty – if you think they are, rinse them with water and pat dry.
Store Korean Cucumber Salad (Oi Muchim) in an airtight container in the refrigerator for 2-3 days. The cucumbers will lose water as they sit, which can lead to the cucumbers turning soft and diluting the flavors of the seasoning. I like to eat mine within the first 1-2 days, as I prefer my cucumbers on the crunchier side.
