Ingredients & Substitutions
Cucumbers:
- 4 cucumbers – Persian or Korean cucumbers work best for their thin skin and crisp texture. English cucumbers are a good backup—just peel off some of the thicker skin if desired.
- 1 tsp salt – Helps draw out water so the cucumbers stay crunchy.
For the Sauce:
- 1 tbsp rice vinegar – Apple cider vinegar can work in a pinch, though rice vinegar gives the best flavor.
- 1 tsp red chili flakes – Korean gochugaru is traditional, but you can use standard chili flakes or even a pinch of cayenne.
- 1 tsp sugar – Balances the heat and tang. Honey or agave can be swapped in.
- 1 tsp sesame oil – Adds a nutty depth. Use toasted sesame oil for the best flavor.
- 1 garlic clove, finely minced – Fresh is best, but ¼ tsp garlic powder works if needed.
- 1 tsp toasted sesame seeds – Add crunch and nuttiness. You can skip or replace with crushed peanuts for a twist.
To Serve:
- Chopped green onion – Optional but highly recommended for freshness and flavor.
Tips for Making Korean Cucumber Salad
- Smash, Don’t Slice: Lightly smashing cucumbers helps them soak up the sauce while keeping their crisp bite.
- Don’t Skip the Salt Step: It makes a huge difference in texture by removing excess water.
- Adjust Heat Level: Use more or less chili flakes depending on your spice preference.
- Serve Fresh: This salad is best enjoyed within a few hours while the cucumbers are still crisp.
FAQs About Korean Cucumber Salad
Can I make this ahead of time?
You can prep the cucumbers and sauce separately ahead of time, then toss together right before serving for maximum crunch.
How long does it last in the fridge?
It’s best eaten fresh, but it can last up to 1 day in the fridge. Beyond that, the cucumbers may soften.
Can I make it non-spicy?
Yes! Simply skip the chili flakes or use a mild chili powder for flavor without the heat.
What can I serve it with?
Korean cucumber salad pairs beautifully with grilled meats, Korean BBQ, rice bowls, or even as a refreshing side to fried chicken.
Is this toddler-friendly?
If your child isn’t sensitive to spice, you can tone down the chili or omit it completely for a kid-friendly cucumber salad.
