Korean cucumber salad is wonderfully crisp when freshly made, but it can quickly turn watery as the cucumbers release moisture and dilute the seasoning.
The key to this Oi Muchim (Korean Spicy Cucumber Salad) is soaking 4 Korean white cucumbers with coarse salt and starch syrup for exactly 20 minutes to draw out excess moisture. Instead of rinsing them afterward, squeeze the cucumbers thoroughly before seasoning them with anchovy fish sauce, maesil syrup, and vinegar. This helps the dressing stay concentrated while keeping the cucumbers firm and crunchy for longer.
The sweet, tangy, and spicy seasoning pairs with the fresh cucumber and Cheongyang chili for a refreshing Korean side dish that goes especially well with rice or pork dishes.

✓ How to Make Korean Cucumber Salad
- Prepare and slice the cucumbers: Trim the bitter ends from all 4 Korean white cucumbers, then slice them into medium-thick rounds—not too thin and not too thick.
- Prepare the vegetables: Thinly slice 1/2 onion. Finely chop 5 stalks of green onion, then thinly slice 1 Cheongyang chili pepper and 1 red chili pepper on the diagonal.
- Salt the cucumbers with starch syrup: Place the sliced cucumbers in a bowl and add 15 ml (1 tbsp) coarse salt and 60 ml (4 tbsp) starch syrup. Toss thoroughly and let sit for 20 minutes. Turn the cucumbers once or twice during this time so they release moisture evenly.
- Squeeze out the moisture: After 20 minutes, do not rinse the cucumbers with water. Using your hands or a clean kitchen cloth, squeeze them very firmly to remove as much liquid as possible. Work in several batches so you can squeeze them thoroughly and maintain their firm, crunchy texture.
- Add the seasoning and toss: Add the onion, green onion, Cheongyang chili pepper, and red chili pepper to the squeezed cucumbers. Add 45 ml (3 tbsp) gochugaru, 15 ml (1 tbsp) anchovy fish sauce, 30 ml (2 tbsp) maesil syrup, 30 ml (2 tbsp) vinegar, 15 ml (1 tbsp) minced garlic, and 7.5 ml (1/2 tbsp) sugar. Toss everything together gently by hand until evenly coated.
- Finish with sesame oil and seeds: Once the seasoning is evenly distributed, add 15 ml (1 tbsp) sesame oil and 30 ml (2 tbsp) sesame seeds. Toss lightly to finish.
✓ Key Tips for Success
- Do not rinse after salting with starch syrup: Salting the cucumbers with both coarse salt and starch syrup draws out a substantial amount of moisture. If you rinse the cucumbers afterward, they can absorb water again and become watery. Skip the rinsing step and squeeze out the released liquid thoroughly to preserve the firm, crunchy texture.
- Remove as much moisture as possible: Four cucumbers contain a lot of water, so do not try to squeeze them all at once. Work in 3–4 smaller batches and squeeze firmly. If too much moisture remains, the dressing will slide off the cucumbers and become diluted as more liquid collects over time.
✓ Serving Tips
- Serve with pork belly or boiled pork: The sweet, tangy, spicy seasoning pairs especially well with rich grilled pork belly or mild Korean boiled pork (suyuk), adding a fresh contrast to the meat.
- Use as a bibimbap topping: Spoon plenty of the crunchy cucumber salad over warm rice, then add a fried egg and a small drizzle of sesame oil for an easy rice bowl.
✓ How to Choose a Good Cucumber
- Shape and thickness: Choose cucumbers that are relatively straight and have an even thickness from top to bottom.
- Firmness: Look for cucumbers with a glossy surface that feel firm rather than soft when held.
- Stem condition: Choose cucumbers with fresh green stems that are not wilted or dried out.

✓ Frequently Asked Questions (FAQ)
Q1. How long should I salt the cucumbers with coarse salt and starch syrup?
Let them sit for exactly 20 minutes. This is enough time to draw out plenty of moisture without making the cucumbers overly soft.
Q2. Why does a lot of liquid collect at the bottom after I season the cucumbers?
This usually happens when the salted cucumbers were not squeezed thoroughly enough or when they were rinsed with water after salting, allowing them to absorb moisture again.
Q3. Can I use sand lance fish sauce or tuna extract seasoning instead of anchovy fish sauce?
Yes. You can substitute the anchovy fish sauce with 15 ml (1 tbsp) sand lance fish sauce or tuna extract seasoning while still adding savory depth to the seasoning.
After salting the cucumbers with coarse salt and starch syrup for 20 minutes, I squeezed them thoroughly without rinsing before adding the seasoning. Even after sitting for a while, very little liquid collected at the bottom, and the cucumbers kept their pleasantly firm, crunchy texture. The savory depth of anchovy fish sauce paired naturally with the sweet-tangy maesil syrup and vinegar, complementing the fresh cucumber flavor.
I’m usually disappointed when cucumber salad becomes watery over time and the seasoning starts to taste diluted, but this method kept both the crunchy texture and concentrated seasoning much better. My family also enjoyed its fresh, clean flavor with warm rice and meat dishes.
If you want to make crisp Korean cucumber salad without excess water, salt the cucumbers with coarse salt and starch syrup for 20 minutes, do not rinse them afterward, and squeeze out the moisture as thoroughly as possible before seasoning. Give this method a try when you need a fresh Korean side dish or a tangy accompaniment for grilled pork belly or suyuk.
