Ingredients You Need

Cucumbers

2 English cucumbers or 4–5 small Persian cucumbers
- English cucumbers bring fewer seeds and a thin skin, so you skip peeling.
- Persian cucumbers stay extra crunchy and work great if you like smaller slices.
- Use regular cucumbers in a pinch, but peel thick skin and scoop out large seeds.

Aromatics and Flavor Base

2–3 cloves garlic, minced
2 green onions, thinly sliced
1–2 teaspoons grated fresh ginger (optional, but adds a nice zing)

I like Korean garlic, which tastes a bit sharper, but any fresh garlic works. Use the white and light green parts of the green onions in the salad and save the dark green tops for garnish.

Seasoning Sauce

1½ tablespoons Korean red pepper flakes (gochugaru), mild or hot
1½ tablespoons soy sauce (use low sodium if you watch salt)
1 tablespoon rice vinegar (unseasoned)
1 tablespoon toasted sesame oil
1–2 teaspoons sugar, honey, or agave
½ teaspoon kosher salt, plus more to taste
1 teaspoon toasted sesame seeds, plus extra for garnish

Use gochugaru specifically, not regular chili powder or crushed red pepper. Gochugaru gives that classic Korean flavor and a deep red color without harsh bitterness. If you need gluten free, use tamari instead of soy sauce and check labels on gochugaru and vinegar.

Optional Add‑Ins

½ small carrot, julienned, for extra crunch and color
¼ small red onion, thinly sliced, for more bite
1 teaspoon fish sauce, for extra umami if you like stronger flavor
Pinch of MSG, if you enjoy that restaurant-style savory depth

Equipment List

Cutting board and sharp chef’s knife
Medium mixing bowl
Small bowl for sauce
Spoon or spatula
Colander or fine mesh strainer
Paper towels or clean kitchen towel

You do not need a stove, oven, or fancy gadgets. A sharp knife and a good playlist handle most of the work.

Tips & Mistakes

Slice cucumbers evenly so they salt and season at the same rate.
Salt cucumbers lightly and let them sit 10–15 minutes, then squeeze out extra water so the salad stays crunchy, not watery.
Do not skip the sugar or sweetener; a small amount balances the heat and salt.
Taste the gochugaru before you add a lot, because some brands run hotter than others.
Mix the sauce separately, then add it to the cucumbers so you adjust flavor easily.
Add sesame oil at the end and avoid drowning the salad; a little goes a long way.
Chill the salad at least 10 minutes before serving so flavors meld and cucumbers stay crisp.
Eat it within a day or two; longer storage softens the cucumbers and dulls the flavor.

How to Make Easy Korean Cucumber Salad Recipe

Step 1: Prep and Salt the Cucumbers

Wash cucumbers and pat them dry. Slice them into thin rounds, about ⅛ to ¼ inch thick, or cut into half moons if the cucumbers feel large. Place slices in a bowl, sprinkle with ½ teaspoon kosher salt, and toss well.

Let the cucumbers sit 10–15 minutes while they release water. Transfer them to a colander, gently squeeze out extra moisture with your hands, then pat dry with paper towels. This step keeps the Easy Korean Cucumber Salad Recipe crisp and flavorful.

Step 2: Mix the Seasoning Sauce

In a small bowl, add soy sauce, rice vinegar, gochugaru, sugar or honey, minced garlic, grated ginger if using, and toasted sesame oil. Stir until the sugar dissolves and the mixture looks smooth and slightly thick. Taste and adjust: add more sugar for sweetness, more vinegar for tang, or more gochugaru for heat.

Drop in the sesame seeds and stir again. The sauce should taste a little stronger than you want the final salad, because the cucumbers will dilute it slightly.

Step 3: Combine and Toss

Place the salted, dried cucumber slices in a clean mixing bowl. Add green onions and any optional veggies like carrot or red onion. Pour the seasoning sauce over the cucumbers.

Toss gently but thoroughly so every slice gets coated. Taste a piece and adjust with a pinch more salt, a splash of soy sauce, or a dash of vinegar if needed.

Step 4: Chill and Serve

Cover the bowl and chill the salad for 10–20 minutes. This short rest lets the cucumbers soak up the flavors while staying crunchy. Give everything a quick toss again before serving and sprinkle extra sesame seeds and green onion on top.

If you like more heat, add a small pinch of gochugaru right before serving for a fresh pop of color and spice. I often do this when I serve it to spice lovers at the table.

Variations I've Tried

Less spicy version: Cut the gochugaru down to 1 teaspoon and add more sesame seeds and a touch more sugar. Kids usually devour this version without complaint.
Extra spicy version: Add a teaspoon of gochujang to the sauce and thin it with a splash of water. This version clings to the cucumbers and hits with deeper heat.
Garlic bomb version: Use 4–5 cloves of garlic and skip ginger. This one works best if everyone eats it so no one can complain.
Crunch party version: Add thin slices of radish and carrot along with the cucumbers. The bowl looks colorful and works nicely on a potluck table.
Low sodium version: Use low sodium soy sauce, reduce added salt, and lean on vinegar, garlic, and sesame oil for flavor. Taste as you go so you still get a bold Easy Korean Cucumber Salad Recipe.

How to Serve Easy Korean Cucumber Salad Recipe

Serve this Easy Korean Cucumber Salad Recipe as a banchan alongside grilled chicken, beef, tofu, or salmon. Spoon it over hot steamed rice for a quick lunch that tastes refreshing and light. Pack it into lunch boxes with leftover protein and some kimchi for a fast meal. It also works as a crunchy topping for noodle bowls or lettuce wraps.

How to store

Store leftovers in an airtight container in the fridge for up to 2 days; the cucumbers soften slightly but still taste great.
Stir the salad before serving again, since the sauce can settle at the bottom.
Skip the freezer, because cucumbers turn mushy and lose their crunch after thawing.
Eat straight from the fridge or let it sit at room temperature 5–10 minutes; no reheating needed.
