Steps
Before you start
- Have a colander ready to drain the cucumbers
- Mince the garlic and thinly slice the green onions before you begin
- If using raw sesame seeds, toast them in a dry skillet over medium heat for 1–2 minutes until fragrant
Prepare the cucumbers
- Rinse 4 medium cucumbers under cool running water and pat dry.
- If using long English cucumbers, cut in half lengthwise, then slice into ½-inch (1.25 cm) thick half-moons.
- If using smaller Kirby or pickling cucumbers, slice into ½-inch (1.25 cm) rounds or batons.
- You should have about 6 cups of sliced cucumber.

Ready when: Cucumbers are evenly sliced
Tip: If your cucumbers are very large or have large seeded centers, scoop out some seeds with a spoon before slicing to prevent the salad from becoming too watery.
Salt and drain cucumbers
- Place the sliced cucumbers in a colander set over a bowl or sink.
- Sprinkle with ½ tsp (3g) kosher salt and gently toss to distribute evenly.
- Let sit undisturbed for 10–15 minutes.
- The salt draws out excess moisture and softens the cucumbers slightly, improving their texture.

Ready when: Liquid has pooled at the bottom of the colander
Tip: Don't skip this step—it removes water and prevents a diluted, soggy salad.
Whisk the dressing
- In a medium bowl, combine 2.5 tbsp (40g) gochujang, 2 tbsp (30ml) soy sauce, 1 tbsp (15ml) rice vinegar, 1 tbsp (15ml) toasted sesame oil, 1 tsp (5g) sugar, and 3 cloves minced garlic.
- Whisk vigorously until the gochujang breaks down completely and the mixture is smooth with no lumps.
- Taste and adjust: add more sugar if too spicy or salty, more soy sauce for depth, or a splash of water to thin if needed.

Ready when: Dressing is smooth and well blended with no lumps of gochujang visible
Tip: Whisk the gochujang hard so it fully incorporates; lumpy dressing won't coat the cucumbers evenly and will be unpleasant to eat.
Rinse and pat cucumbers dry
- If the drained cucumbers taste overly salty, rinse them quickly under cool running water and drain well.
- Pat them gently (don't squeeze hard) with paper towels or a clean kitchen towel to remove excess moisture without breaking the slices.

Ready when: Cucumbers are damp but not dripping wet
Tip: A gentle pat is sufficient; aggressive squeezing damages the delicate cucumber slices.
Toss cucumbers with dressing
- Transfer the drained cucumbers to a large bowl.
- Pour the prepared gochujang dressing over them and gently toss with a spoon or rubber spatula, using a folding motion to coat every piece evenly without breaking them.

Ready when: All cucumber pieces are evenly coated with the glossy red-brown dressing
Chill until flavors meld
- Cover the bowl with plastic wrap or a lid and refrigerate for at least 15–20 minutes.
- This allows the flavors to marry and the cucumbers to absorb the dressing while remaining crisp.
- The salad may also be served at room temperature if you prefer it immediately, though chilling enhances the flavors.

Garnish and serve
- Just before serving, scatter 2.5 tbsp (22g) toasted sesame seeds evenly over the salad.
- Sprinkle the 3 sliced green onion stalks on top, using the white and light green parts.
- You can gently toss once or twice to combine, or leave some garnish on top for visual presentation.
- Serve chilled or at room temperature.

Tip: Add the sesame seeds and green onions just before serving so they stay crisp and don't soften from prolonged contact with the dressing.
Good to know
Tips
- Toast your own sesame seeds in a dry skillet over medium heat for 1–2 minutes if they are not already toasted—this brings out their nutty, complex flavor and makes a noticeable difference.
- The salting step (step 2) is crucial: it removes excess water from the cucumbers and prevents the finished salad from becoming soggy and diluted as it sits.
- If the dressing tastes too strong, spicy, or salty, whisk in a tablespoon of water or rice vinegar to mellow and balance the flavors.
- This salad is best eaten within a few hours of assembly. Over time, the cucumbers continue to release water and soften. If you have leftovers, drain excess liquid before serving the next day.
Make ahead
Yes. Prepare the salad through step 6 (chill) up to 4 hours ahead and refrigerate. Add the toasted sesame seeds and fresh green onion garnish just before serving so they retain their crunch. If the salad has released significant liquid, drain some of it off before serving.
Storage & reheating
Refrigerator: Up to 2 days, though best eaten on the first day for optimal crunch and flavor. If the salad has released excess liquid, drain it before serving. Room temperature: Best served within 1 hour; not recommended for more than 2 hours as the cucumbers will continue to soften and release water. Freezer: Not suitable for this salad.
Substitutions
- English cucumbers (or Kirby cucumbers) → Kirby cucumbers, Persian cucumbers, or pickling cucumbers. These varieties are slightly crunchier and will hold their texture longer; they are often smaller, so you may need 5–6 of them.
- gochujang (Korean red chili paste) → 2 tbsp gochugaru (Korean red chili flakes) mixed with 1 tbsp honey and 1 tbsp soy sauce, or 2–2.5 tbsp sriracha thinned with 1 tbsp lime juice. The flavor profile will differ—gochujang has a deeper, sweeter fermented note. Sriracha is spicier and more vinegary. Adjust to your taste preference.
- sesame oil, toasted → Neutral oil such as grapeseed, sunflower, or vegetable oil. This changes the flavor noticeably, as sesame oil adds a distinctive nutty richness. The salad will taste fresher and less aromatic without it.
- rice vinegar → Apple cider vinegar or distilled white vinegar (use 1.5 tsp instead of 1 tbsp, as these are more acidic). Rice vinegar is milder and more traditional. Other vinegars will make the dressing more sharp and tangy.
