Ingredients
- 1 lb Kirby or Persian Cucumbers (about 4-5 small cucumbers)
- 1 teaspoon Sea Salt
- 2 Green Onions, thinly sliced
- 2 cloves Garlic, minced
- 2 tablespoons Gochugaru (Korean chili flakes)
- 1 tablespoon Rice Vinegar
- 1 tablespoon Soy Sauce
- 2 teaspoons Toasted Sesame Oil
- 1 teaspoon Sugar
- 1 teaspoon Toasted Sesame Seeds
Step-by-Step Instructions
- Prep the Cucumbers: Wash the cucumbers thoroughly. Slice them into 1/4-inch thick rounds. Place the slices in a medium bowl and sprinkle with the sea salt. Toss gently to coat.
- Salt and Drain: Let the cucumbers sit for 10-15 minutes. The salt will draw out excess water. After 15 minutes, you will see a pool of liquid at the bottom of the bowl.
- Rinse and Dry: Drain the cucumbers and rinse them thoroughly under cold water to remove the excess salt. Gently squeeze the cucumbers with your hands or pat them dry with paper towels to remove as much moisture as possible.
- Make the Dressing: In the same bowl, combine the green onions, minced garlic, gochugaru, rice vinegar, soy sauce, sesame oil, and sugar.
- Toss to Combine: Add the drained and dried cucumber slices back to the bowl with the dressing. Add the toasted sesame seeds. Toss everything together until the cucumbers are evenly coated in the sauce.
- Serve: You can serve the salad immediately for the crunchiest texture, or let it marinate in the refrigerator for 30 minutes for the flavors to meld even more.
Tips & Variations
- Pro Tip: Don’t skip the salting step! It is the most important step for ensuring the cucumbers stay crisp and don’t water down the sauce.
- Cucumber Choice: Kirby or Persian cucumbers are best because they have thin skin and fewer seeds. If using a regular English cucumber, you may want to scoop out some of the seeds.
- Adjust the Spice: Gochugaru can vary in heat. Start with 1-2 tablespoons and add more if you like it extra spicy.
- Add Veggies: Add thinly sliced onion or shredded carrots for extra color and crunch.
Frequently Asked Questions (FAQ)
- How do I store Korean cucumber salad?
- Store leftovers in an airtight container in the refrigerator for up to 3 days. The cucumbers will soften slightly but will still be delicious.
- Can I make this ahead of time?
- It’s best served the day it’s made for maximum crunch. However, you can make it a few hours in advance and keep it chilled in the refrigerator.
- What is Gochugaru and is there a substitute?
- Gochugaru is a Korean chili powder with a vibrant red color and a smoky, fruity flavor. There isn’t a perfect substitute, but in a pinch, you could use a smaller amount of red pepper flakes, though the flavor and color will be different.
Serving Suggestions
