Spicy Cucumber Salad, also known as Oi Muchim, is a popular Korean side dish that's perfect for the summer. This refreshing salad features a delightful combination of fresh cucumbers, onions, garlic chives, and a spicy, tangy dressing. In just a few simple steps, you'll have a flavorful, zesty side dish that pairs well with a variety of meals. So let's get cooking!
This delicious Korean Spicy Cucumber Salad pairs perfectly with grilled meats like Korean BBQ, or as a refreshing side dish for rice dishes and noodle bowls. Its tangy, spicy flavor also complements fish and tofu dishes.
If you can't find gochugaru (Korean red pepper flakes), you can substitute it with regular red pepper flakes or a mix of paprika and cayenne pepper for a similar spicy kick.
This recipe serves 4, with approximately 150 grams per serving.
How long does this Korean Spicy Cucumber Salad last in the fridge? This salad is best enjoyed fresh, but it can last up to 2 days in the refrigerator. Store in an airtight container to maintain freshness.
Can I make this salad ahead of time? Yes! In fact, letting the salad sit for a few hours in the fridge allows the flavors to meld and intensify.
Is this salad gluten-free? This recipe is gluten-free as written, but always double-check the ingredients to ensure they don't contain hidden gluten.
How do I adjust the spiciness of the salad? You can control the spiciness by adjusting the amount of gochugaru or substituting it with a milder chili pepper.

Refreshing and flavorful! I’ll double the batch next time because it disappears so fast.

Great summer salad. Next time I’ll reduce the gochugaru slightly—was a bit spicy for my kids!

Reminds me of my mom’s Oi Muchim. Simple and authentic. I did use Korean cucumber for extra crunch.
