This spicy Korean cucumber salad, also known as oi muchim, is a quick and easy banchan side dish made with thinly sliced cucumbers. It’s bold, crunchy, and perfect for serving cold alongside rice bowls, grilled mains, or as part of a Korean-inspired meal.
Place two chopsticks or skewers on either side of each cucumber. Use a sharp knife to make thin vertical cuts along the cucumber, stopping at the chopsticks to avoid slicing all the way through. Then flip the cucumber and repeat the cuts at a diagonal angle to create an accordion effect.
Sprinkle cucumbers with salt and let them sit for 10 minutes to release excess moisture. Drain the cucumber and transfer it to a bowl. Fan the cucumbers to open up the layers.
In a small bowl, whisk together soy sauce, chili oil, sugar, sesame oil, garlic, and rice vinegar until the sugar dissolves.
Pour the dressing over the accordion cucumbers. Toss gently, making sure it gets between the slices. Garnish with sesame seeds and serve immediately or chill for later.
Notes
Use thin-skinned cucumbers for the best texture and flavor. Persian or English cucumbers work great for Asian cucumber recipes.
Salting is key. Don’t skip it. This step prevents the salad from becoming watery and helps concentrate flavor.
Chili oil brings a deeper, smokier heat compared to traditional gochugaru. If you want to use gochugaru instead, swap the oil for 1-2 teaspoons of flakes.
Taste the dressing before tossing and adjust for heat or sweetness.
