Tangy and spicy Korean cucumber salad is the kind of side dish that wakes up your whole table with just a handful of ingredients and bright flavors. It is quick enough for a weeknight meal and always delivers the crunch and kick you crave with Korean barbecue or even a simple bowl of rice.
The first time I made this salad I remember how the dressing’s scent filled my kitchen I reached over the bowl for a taste test and ended up eating half the cucumbers before dinner even started
Ingredients
- Medium cucumbers: Choose ones that are firm and free of blemishes This makes the salad extra crisp and refreshing
- Salt: Draws out water and helps ensure the cucumbers keep their crunch
- Rice vinegar: Brings gentle acidity Balance is best when using unseasoned rice vinegar for a clean tang
- Soy sauce: Adds umami depth Look for a good quality naturally brewed bottle
- Gochugaru (Korean red pepper flakes): Provide signature heat and vibrant color For authentic flavor use coarse gochugaru not fine powder
- Sugar: Balances the acidity and heat Use white sugar or try a touch of honey for a twist
- Garlic, minced: Gives a deep aromatic kick Freshly minced makes a big difference in the final taste
- Sesame oil: Toasted brings nutty fragrance and rounds out all flavors Choose a dark aromatic bottle for best results
- Sesame seeds: Add crunch and a toasty note Lightly toast them before adding for extra flavor
- Green onions, sliced: Fresh bite and a pop of color Use the firmest brightest green you can find
Step-by-Step Instructions
- Prepare the Cucumbers:
- Sprinkle the sliced cucumbers with salt in a large bowl and toss thoroughly Let them sit untouched for ten to fifteen minutes The salt will start to pull out excess water so the salad does not get soggy
- Make the Dressing:
- Whisk together the rice vinegar soy sauce gochugaru sugar minced garlic and sesame oil in a separate bowl Keep whisking until the sugar is completely dissolved and the dressing looks creamy
- Combine:
- Gently squeeze the cucumbers with your hands or a clean towel to remove as much moisture as possible Add them to the bowl with the dressing and toss until every slice glistens and is coated in the seasoning
- Garnish:
- Scatter sesame seeds and sliced green onions over the top just before serving for extra crunch and brightness
- Chill:
- Place the salad in the fridge for at least fifteen minutes This helps the flavors mingle so every bite is perfectly tangy and spicy

Ever since I discovered how to balance the right level of spice and vinegar my family never lets this salad sit for long We love the green onion topping for a burst of sharpness that ties it all together
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to two days The salt will continue to draw moisture so it is best consumed within a day for optimal crunch If excess liquid accumulates simply drain before serving
Ingredient Substitutions
If you do not have gochugaru try a mix of crushed red pepper and a pinch of smoked paprika For extra tang use apple cider vinegar instead of rice vinegar If cucumbers are thin skinned you can skip peeling
Serving Suggestions
Serve alongside grilled meats or with a bowl of steamed rice It is a wonderful palate cleanser between spicy or fried dishes Try folding it into lettuce wraps or as a topping for burgers and hot dogs for a twist
