Oi Muchim is one of those dishes that looks simple but delivers a punch of flavor that elevates any meal. It’s served cold and pairs beautifully with grilled meats, rice, noodles, or Korean barbecue (samgyeopsal).

Ingredients

Main Ingredients

• 2 large cucumbers (preferably Korean or Persian cucumbers)
• 1 teaspoon salt
• 2 green onions, finely chopped

For the Spicy Dressing

• 1½ tablespoons gochugaru (Korean red pepper flakes)
• 1 tablespoon soy sauce
• 1 teaspoon rice vinegar
• 1 teaspoon sugar (or honey)
• 1 teaspoon minced garlic
• 1 teaspoon sesame oil
• 1 teaspoon toasted sesame seeds
• (Optional) ½ teaspoon gochujang (Korean chili paste) for extra heat

Step-by-Step Preparation Method

Step 1: Prepare the Cucumbers

1. Wash cucumbers and slice them into thin rounds (about ¼ inch thick).
2. Sprinkle salt evenly over the slices and toss gently.
3. Let sit for 10 minutes to draw out excess moisture.
4. After 10 minutes, gently squeeze out the water using your hands or paper towel. This step ensures the cucumbers stay crunchy, not soggy.

Step 2: Make the Spicy Dressing

1. In a medium bowl, combine gochugaru, soy sauce, rice vinegar, sugar, garlic, sesame oil, and sesame seeds.
2. Mix until the sugar dissolves and the dressing is well-blended.
3. Adjust to taste — add more vinegar for tang, more sugar for balance, or more gochugaru for spice.

Step 3: Toss Everything Together

1. Add the drained cucumber slices and chopped green onions into the bowl with the dressing.
2. Toss gently until all cucumbers are evenly coated with the spicy mixture.

Step 4: Rest and Serve

1. Let it rest for 5 minutes at room temperature to allow the flavors to develop.
2. Serve immediately or refrigerate for 15–20 minutes for a chilled version.

How to Serve

• Serve the Korean Spicy Cucumber Salad as a banchan (Korean side dish) alongside rice and main dishes like bulgogi, bibimbap, or kimchi fried rice.
• It’s also great with grilled meats, tofu, or noodle bowls.
• For presentation, sprinkle extra sesame seeds on top before serving.
• Serve chilled for maximum crunch and refreshment.

Recipe Tips

• Use firm cucumbers for best crunch (Korean, Persian, or English cucumbers work best).
• Salting step is crucial — it removes excess moisture so the cucumbers stay crisp.
• For extra heat, add a small amount of gochujang or Korean chili oil.
• If serving later, don’t mix too early — cucumbers will release water and dilute the flavor.
• Adjust seasoning to your liking — balance salt, spice, and tang based on preference.

Variations

1. Mild Version: Reduce gochugaru by half or skip gochujang.
2. Garlic-Lovers’ Version: Double the minced garlic for a stronger punch.
3. Sweet and Tangy: Add a little more vinegar and honey for a brighter flavor.
4. Cucumber-Carrot Mix: Add thin carrot ribbons for color and sweetness.
5. Tofu Salad Twist: Add cubed firm tofu to make it a protein-packed salad.
6. Sesame Crunch: Top with roasted peanuts or crushed roasted seaweed for texture.

Freezing and Storage Time

• Refrigerator: Store in an airtight container for up to 2 days.
  (Note: The salad will release some water over time but still tastes great!)
• Freezer: Not recommended — cucumbers lose texture when frozen.
• Make Ahead: Mix dressing and cucumbers separately, then combine just before serving for best crunch.

Special Equipment Needed

• Sharp knife or mandoline slicer
• Mixing bowl
• Measuring spoons
• Strainer or paper towel (for draining cucumbers)

FAQ

Q3: Can I make this less spicy?
Absolutely — reduce or omit gochugaru and gochujang, and increase sugar or vinegar slightly for balance.

Q4: How do I keep the cucumbers crunchy?
Salting and draining the cucumbers before mixing with the dressing helps retain their crisp texture.

Q5: Is Oi Muchim vegan?
Yes, it’s 100% vegan — no animal products are used.
