Ingredients You Need

Cucumbers

2 English cucumbers or 4 to 5 small Persian cucumbers
- English cucumbers give thin skin and fewer seeds.
- Persian cucumbers stay extra crunchy and work great for meal prep.
- Avoid thick, waxy standard cucumbers unless you peel and seed them.

Main Seasoning

1 ½ tablespoons soy sauce
- Use low sodium if you watch salt.
- Use tamari or coconut aminos for gluten free.
1 tablespoon rice vinegar
- Seasoned rice vinegar adds a touch more sweetness.
- Use apple cider vinegar in a pinch.
1 tablespoon sugar
- White sugar dissolves quickly.
- Use honey, agave, or maple syrup if you prefer.
1 tablespoon Korean red pepper flakes (gochugaru)
- Use fine or medium grind for best texture.
- Reduce to 1 to 2 teaspoons for mild heat.
- Do not swap with standard chili powder; it changes flavor completely.
1 teaspoon toasted sesame oil
- Use a good quality brand like Kadoya or Ottogi for deep nutty flavor.
- A little goes a long way, so measure it.
2 to 3 cloves garlic, very finely minced or grated
- Use a microplane for a smoother dressing.
- Garlic powder works in a pinch, but fresh tastes better.
1 to 2 green onions, thinly sliced
- Use both white and green parts for flavor and color.
1 teaspoon sesame seeds
- Toast them in a dry pan for 1 to 2 minutes until fragrant.
- White or black sesame seeds both work.
½ teaspoon kosher salt, plus more to taste
Freshly ground black pepper, a pinch

Optional Add Ins

1 teaspoon fish sauce for deeper umami
1 teaspoon finely minced ginger
1 teaspoon gochujang for a thicker, slightly sticky dressing
½ teaspoon sugar extra if you like a sweeter banchan style

Pantry Shortcuts

Use pre-minced garlic from a jar if you feel tired or rushed.
Use pre-toasted sesame seeds to skip a step.
Use seasoned rice vinegar and reduce the sugar slightly.

Equipment List

Cutting board and sharp knife
Medium mixing bowl
Small bowl for mixing dressing
Measuring spoons
Spoon or tongs for tossing
Colander or strainer if you salt and drain cucumbers

Quick Tips & substitutions

Slice cucumbers into thin rounds or half moons so the dressing coats each piece.
Salt the cucumber slices lightly and rest them 10 minutes, then squeeze gently to remove extra water for maximum crunch.
Use tamari or coconut aminos instead of soy sauce for gluten free.
Swap sugar with honey, agave, or a low carb sweetener like allulose or erythritol.
Reduce gochugaru to 1 teaspoon for mild heat or increase to 1 ½ tablespoons for spicy.
Skip fish sauce for vegan and rely on soy sauce or tamari for umami.
Add a splash of extra rice vinegar if you like a sharper, more pickled flavor.
Serve right away for the crunchiest texture or chill 10 to 15 minutes for deeper flavor.

How to Make Easy Korean Cucumber Salad Recipe

Step 1: Prep and Slice the Cucumbers

Wash cucumbers and pat them dry so they do not water down the dressing. Slice them into thin rounds about ⅛ to ¼ inch thick, or cut them in half lengthwise and slice into half moons. Place all cucumber slices in a mixing bowl.

Step 2: Salt and Drain for Extra Crunch

Sprinkle ½ teaspoon kosher salt over the cucumber slices and toss to coat. Let them sit for about 10 minutes on the counter so they release some water. After 10 minutes, squeeze the cucumbers gently with clean hands or press them in a strainer to remove excess liquid, then return them to the bowl.

Step 3: Mix the Dressing

In a small bowl, add soy sauce, rice vinegar, sugar, gochugaru, sesame oil, minced garlic, and a pinch of black pepper. Stir until the sugar dissolves and the mixture looks uniform. Taste a tiny bit and adjust salt, sugar, or gochugaru to match your heat and sweetness preference.

Step 4: Toss Cucumbers With Seasoning

Pour the dressing over the drained cucumber slices. Add sliced green onions and sesame seeds. Toss gently with a spoon or tongs until the cucumbers look evenly coated and glossy.

Step 5: Rest Briefly and Serve

Let the salad sit for 5 to 10 minutes so the cucumbers soak up the seasoning. Taste again and adjust with a splash of vinegar, a pinch of sugar, or a sprinkle of gochugaru if you want more kick. Transfer to a serving plate or small side dish bowls and sprinkle a few extra sesame seeds on top.

Recipe Variations

Gluten free: Use tamari or certified gluten free soy sauce and check your gochugaru label.
Vegan: Skip fish sauce and stick with soy sauce or tamari, and use sugar or maple syrup.
Low carb: Use a zero calorie sweetener like allulose, monk fruit, or erythritol instead of sugar.
Extra spicy: Add 1 teaspoon gochujang or a drizzle of Korean chili oil.
Mild version: Cut gochugaru down to 1 teaspoon and add a bit more sugar for balance.
Crunch boost: Add thinly sliced radish or carrots for extra color and texture.
Protein add in: Toss in chilled tofu cubes or sliced boiled egg on the side for a fuller meal.

Ways to Serve

Serve as a banchan side dish with steamed rice and grilled chicken or tofu.
Pack it in lunch boxes next to kimchi, roasted veggies, and rice.
Spoon it over cold noodles with extra sesame seeds for a quick summer meal.
Pair it with grilled fish and a simple salad for a light dinner.
Use it as a crunchy topping for grain bowls with quinoa, brown rice, or cauliflower rice.

Storage Success

Store leftover Korean cucumber salad in an airtight container in the fridge. Eat it within 2 to 3 days for the best crunch and flavor, since cucumbers soften as they sit. If the salad releases extra liquid, stir it and taste; add a pinch of salt, a splash of rice vinegar, or a sprinkle of gochugaru to refresh the flavor. Serve it chilled straight from the fridge or let it sit on the counter for 5 minutes to take the chill off.
