- 1 tsp salt
- 1.5 tsp soy sauce
- 1 tsp minced garlic
- 3 tbsp rice vinegar

How to Make Korean Cucumber Salad:
Step-by-Step Instructions:
Step 1: Prepare the Cucumbers Wash and slice the cucumbers into thin rounds, approximately 1/8-inch thick. If using regular cucumbers, you may want to peel them partially in strips for a decorative look, or leave the skin on for extra nutrition and crunch.
Step 2: Salt the Cucumbers Place the sliced cucumbers in a large bowl and sprinkle with salt. Toss well to ensure all pieces are coated. Let them sit for 10-15 minutes to draw out excess moisture.
Step 3: Drain and Rinse After the cucumbers have released their water, drain them in a colander and rinse thoroughly under cold water to remove excess salt. Pat dry with paper towels or gently squeeze the cucumbers to remove as much water as possible.
Step 4: Make the Dressing In a small bowl, whisk together soy sauce, minced garlic, rice vinegar, chili oil, sugar, and sesame oil until the sugar is completely dissolved.
Step 5: Combine and Serve Return the drained cucumbers to the large bowl and pour the dressing over them. Toss well to coat evenly. Garnish with sesame seeds and diced green onions if desired. Serve immediately for the best texture and flavor.
Helpful Tips:
- Choose the right cucumbers: Mini cucumbers or Persian cucumbers work best as they have fewer seeds and a crispier texture. If using regular cucumbers, remove the seeds for better results.
- Don’t skip the salting step: This crucial step removes excess water from the cucumbers, preventing the salad from becoming watery and ensuring the dressing adheres properly.
- Adjust the heat: Start with less chili oil if you’re sensitive to spice, or add Korean gochugaru (red pepper flakes) for authentic flavor.
- Fresh is best: This salad is best enjoyed fresh but can be refrigerated for up to 2 days.

Frequently Asked Questions:
Q: Can I make this salad ahead of time? A: While this Ultimate Korean Cucumber Salad is best enjoyed fresh, you can prepare it up to 2 hours in advance. However, the longer it sits, the more water the cucumbers will release, potentially diluting the flavors.
Q: What can I substitute for chili oil? A: You can use Korean gochugaru (red pepper flakes), sriracha, or even a pinch of cayenne pepper mixed with a little vegetable oil.
Q: Is this salad spicy? A: The spice level is adjustable. With 2-3 teaspoons of chili oil, it has a moderate heat level. Reduce the amount for a milder version or increase for more heat.
Q: Can I use English cucumbers? A: Yes, but be sure to remove the seeds and extra moisture. English cucumbers tend to be more watery than mini cucumbers.
