How to Make Spicy Korean Smashed Cucumber Salad

  1. Smash the cucumbers:
    Wash and trim the ends. Use the flat side of a knife or rolling pin to smash cucumbers until slightly cracked. Slice into bite-sized chunks.
  2. Salt & drain:
    Place cucumbers in a bowl with 1 tsp kosher salt. Let sit for 10 minutes, then drain excess liquid. This helps improve texture and flavor.
  3. Make the dressing:
    In a small bowl, combine rice vinegar, soy sauce, sesame oil, garlic, sugar, and gochugaru. Stir well to combine.
  4. Toss it together:
    Add the drained cucumbers to the dressing and toss to coat evenly.
  5. Finish with sesame & green onion:
    Sprinkle with toasted sesame seeds and sliced green onion. Serve immediately or chill for 15–30 minutes for deeper flavor.

What to Serve With It

This dish makes a perfect side to anything grilled, spicy, or saucy. Try it with:

  • Korean BBQ (bulgogi, galbi)
  • Bibimbap or rice bowls
  • Kimchi fried rice
  • Korean fried chicken
  • Grilled tofu or salmon
  • Cold soba noodles

Tips for Success

  • Smash gently — you want cracked texture, not mush
  • Salt and drain to prevent watery salad
  • Use gochugaru, not regular chili flakes, for authentic flavor

Frequently Asked Questions

What kind of cucumbers work best?
Persian or mini cucumbers are ideal — thin-skinned and crunchy. Avoid waxy-skinned cucumbers unless peeled.

What if I don’t have gochugaru?
You can substitute with crushed red pepper flakes, but reduce the amount and note it will be spicier and less smoky.

Can I make this ahead?
Yes! It’s great made 1–2 hours ahead and kept chilled. Just don’t add sesame seeds until ready to serve.

Is this salad spicy?
Yes, but you can adjust the heat easily by lowering the amount of gochugaru.
