A crisp, spicy, sesame-dressed side dish you can make in 15 minutes with cucumbers straight from the garden.
1. Ingredients
• 3–4 Korean or Persian cucumbers (about 400 g) — English cucumber works too, halve lengthwise and scoop out seeds first.
• 1 tbsp gochugaru (Korean red pepper flakes) · 1 tbsp toasted sesame oil · 1 tbsp soy sauce · 1 tsp rice vinegar · 1 tsp sugar · 1 clove garlic, minced · 1 tsp toasted sesame seeds · ½ tsp fine salt (for salting step).
Optional: thinly sliced green onion, a pinch of MSG for extra umami, or a splash of fish sauce instead of soy sauce for deeper flavour.
2. Step-by-Step Method
Step 1: Slice cucumbers into 3 mm coins or diagonal half-moons. Toss with ½ tsp salt in a colander and let sit 10 minutes — this draws out excess water so the dressing clings instead of pooling. Gently squeeze out liquid, but don’t rinse.
Step 2: While cucumbers drain, whisk together gochugaru, sesame oil, soy sauce, rice vinegar, sugar, and garlic in a mixing bowl until the sugar dissolves.
Step 3: Add drained cucumbers to the dressing and toss gently with your hands or tongs until evenly coated. Sprinkle with sesame seeds and green onion. Serve immediately for maximum crunch, or chill 15 minutes for deeper flavour.
3. Substitutions & Variations
No gochugaru? Use ½ tbsp mild paprika + ¼ tsp cayenne for similar colour and gentle heat. For soy-free, swap soy sauce for coconut aminos. Rice vinegar can be replaced with apple cider vinegar (use slightly less — it’s sharper).
For a non-spicy version kids enjoy, skip the gochugaru entirely and add an extra teaspoon of sesame oil and a pinch of sugar. You can also add shredded carrot or thinly sliced radish for colour and crunch.
4. Serving Ideas
This salad is a classic Korean banchan (side dish). Serve it alongside steamed rice, grilled bulgogi, or fried chicken for a refreshing contrast. It also pairs beautifully with bibimbap, kimbap, or any noodle soup.
For a quick weeknight bowl, top jasmine rice with this cucumber salad, a fried egg, and a drizzle of gochujang mayo. It transforms plain rice into something exciting in minutes.
5. Storage & Make-Ahead Tips
This salad is best eaten within 2 hours of dressing for peak crunch. If you need to prep ahead, salt and drain the cucumbers up to 4 hours in advance and store covered in the fridge — then toss with dressing just before serving.
Leftovers keep 1 day in the fridge but will soften. They’re still tasty — just different in texture. Never freeze this salad; cucumbers turn mushy once thawed.
6. Tips for the Best Texture
The salting step is non-negotiable — it removes just enough moisture so cucumbers stay snappy instead of watery. Don’t skip it, and don’t over-salt. Ten minutes is the sweet spot.
Use Korean or Persian cucumbers if possible — they have thin skin, tiny seeds, and a natural crunch that English cucumbers can’t match. If using English cucumber, halve it, scoop out the seedy centre, and slice into half-moons.
Frequently Asked Questions
Can I use regular cucumbers for this recipe?
Yes — use English or Japanese cucumbers. Avoid thick-skinned slicing cucumbers as they hold too much water. If you must use them, peel, halve, deseed, and extend the salting time to 15 minutes.
How spicy is this korean cucumber salad?
With 1 tbsp gochugaru it’s mildly spicy — a gentle warmth most adults enjoy. Reduce to 1 tsp for very mild heat, or increase to 1½ tbsp if you like more kick.
What is gochugaru and where can I buy it?
Gochugaru is coarsely ground Korean red pepper flakes — smoky, slightly sweet, and moderately hot. Find it at Asian grocery stores or online. Look for sun-dried (태양초) for the best flavour.
Can I make this salad ahead of time?
Prep the cucumbers (salt and drain) up to 4 hours ahead. Toss with dressing no more than 15–30 minutes before serving for the crispest result. Dressed leftovers are fine next day but softer.
