The first time I made this, I ate half the bowl standing at the fridge with a fork. No regrets, no shame.
Cold crunchy cucumbers, smoky heat from the gochugaru, sesame seeds doing their nutty thing, a little tang from the rice vinegar to keep it bright?? Ten minutes. SEVEN ingredients. And it goes with literally anything you’re making for dinner tonight.
What Is Gochugaru?
- KOREAN RED PEPPER FLAKES ground from sun-dried chilis into coarse, smoky bits with fruity undertones!
- NOT THE SAME as cayenne or crushed red pepper (those lack gochugaru’s signature sweetness and texture)
- SNAG A BAG at Asian markets, well-stocked supermarkets, or online retailers
- HEAT VARIES WILDLY by brand…. start with less, taste, then adjust!
- LASTS MONTHS in a sealed jar kept away from direct sunlight
- NO REAL SUBSTITUTE exists, but gochujang paste can pinch-hit (use way less, it’s thicker!)
Persian vs. English Cucumbers
Persian cucumbers are the BEST pick here… they’re small, seedless, and have thin skin that you DO NOT need to peel. Just chop and toss. Their lower water content means your dressing won’t get diluted after marinating!
English cucumbers work as a backup, but they’re longer, slightly more watery, and have bigger seeds you’ll want to scoop out. Cut them into 1/2 inch pieces to match the recipe. If using English, salt the pieces first, let them sit for 5 minutes, then drain the liquid…. this prevents a soggy salad situation.
Whatever you do, skip the standard waxy cucumbers. Thick skins, giant seeds, watery flesh… NOT what you want soaking up sesame oil and gochugaru. *shudders*
How to Keep Cucumbers Crispy
Crispy cucumbers are non-negotiable. Here’s how to nail it every time.
- Cut cucumbers RIGHT before dressing. Once sliced, moisture loss and oxidation start fast (think minutes, not hours).
- Skip the pre-salting. Salt pulls water out and turns them limp before the dressing even hits.
- Dress no earlier than 10 minutes before serving. Vinegar breaks down the cucumber’s structure the longer it sits.
- Keep them CHILLED until you eat. Cold equals firm, room temp equals soggy.
- Toss gently. Aggressive mixing bruises the flesh and releases trapped water.
Make It Your Own: Easy Swaps
- Persian cucumbers swap for English or mini cukes. Regular works too…. scoop the watery seeds out first.
- Gochugaru becomes red pepper flakes (loses smoky depth). Chili powder in a REAL pinch.
- Soy sauce becomes tamari or coconut aminos. Cut added salt if coconut aminos.
- Swap rice vinegar for apple cider vinegar or fresh lime (different flavor, still tasty).
- Granulated sugar swaps for honey or maple syrup. Dissolve the same way!
How Long Does It Keep?
Eat it FRESH….that’s when those cucumbers are snappy, the dressing hits right, and everything feels ALIVE! The flavors haven’t fully soaked into the cucumbers yet, and that crunch is PEAK.
Stash leftovers in an airtight container in the fridge and you’ve got roughly 2 to 3 days before things slide. The cucumbers release water over time (totally normal), softening up and diluting the dressing, so drain off the excess and give it a quick toss before serving.
DO NOT freeze this. Cucumbers become waterlogged mush once thawed and nobody wants that texture, plus the dressing separates weirdly.
If you’re meal prepping, keep the dressing SEPARATE from the cucumbers until you’re ready to eat. Your future self will THANK YOU, especially on a busy weeknight when you need a side FAST.

Ingredients
- 4 persian cucumbers, chopped into 1/2 inch pieces
- 1 tbsp korean chili flakes (gochugaru)
- 1 tbsp sesame seeds
- 3 tsp soy sauce
- 1/2 tsp sesame oil
- 1 tsp rice vinegar
- 1/2 tsp granulated sugar
Step 1: Whisk the Marinade
- 1 tbsp Korean chili flakes (gochugaru)
- 3 tsp soy sauce
- 1/2 tsp sesame oil
- 1 tbsp sesame seeds
- 1 tsp rice vinegar
- 1/2 tsp granulated sugar
In a medium-sized bowl, whisk together the gochugaru, soy sauce, sesame oil, sesame seeds, rice vinegar, and granulated sugar until well combined.
Make sure the sugar is dissolved, and the mixture is uniform in texture.
Step 2: Coat the Cucumber Slices
- 4 Persian cucumbers, chopped into 1/2 inch pieces
Add the chopped cucumbers to the bowl with the dressing.
Toss well to ensure the cucumbers are evenly coated with the mixture.
This is when all those flavors start absorbing into the cucumbers—if you want a little more heat or tang, feel free to adjust the seasoning to your taste.
I sometimes add sliced green onions at this point for an extra layer of flavor, if I have them on hand.
Step 3: Chill and Absorb Flavors
Allow the cucumber salad to marinate in the refrigerator or at room temperature for about 10 minutes.
This gives the cucumbers time to soak up all the delicious flavors before serving.
Enjoy your refreshing, spicy cucumber salad!
