Ingredients You Need

Cucumbers

2 English cucumbers, thinly sliced
- English cucumbers stay crisp and have fewer seeds.
- Use Persian cucumbers as a great swap.
- If you only have standard cucumbers, peel them and scoop out large seeds.

Seasoning and flavor

1 to 1½ tablespoons Korean red pepper flakes (gochugaru)
- Use coarse gochugaru for the best texture.
- Reduce to 1 teaspoon for mild heat or increase for extra spice.
1½ tablespoons soy sauce
- Use low sodium if you watch salt.
- Use tamari or coconut aminos for a gluten free version.
1 tablespoon rice vinegar
- Unseasoned rice vinegar gives better control over salt and sugar.
- White vinegar works in a pinch but tastes sharper.
1 tablespoon sugar
- Use white sugar for clean flavor.
- Swap with honey or maple syrup if you prefer.
1 teaspoon kosher salt, plus more to taste
2 to 3 cloves garlic, very finely minced or grated
1 teaspoon toasted sesame oil
1 tablespoon toasted sesame seeds
2 green onions, thinly sliced

Pantry shortcuts and brand notes

Use pre-minced garlic from a jar when you feel tired; just drain extra liquid.
Use pre-toasted sesame seeds to save time.
Choose a good quality Korean gochugaru; brands like Chung Jung One or Wang give reliable flavor and color.

Equipment list

Quick Tips & substitutions

Slice cucumbers thinly and evenly so they absorb flavor at the same rate.
Salt the cucumbers first, then drain, to pull out extra water and keep the salad crisp.
Use tamari instead of soy sauce to keep the salad gluten free.
Swap sugar with honey or maple syrup for a more rounded sweetness.
Use less gochugaru for kids or spice sensitive guests, then sprinkle extra on your own serving.
Add a splash more rice vinegar if you like a sharper, tangier bite.
Use Persian cucumbers when you want extra crunch and fewer seeds.
Mix the dressing in a separate bowl so you can taste and adjust before it hits the cucumbers.
Toss gently so the cucumber slices stay intact and do not bruise.
Chill the salad at least 10 minutes so flavors settle and deepen.

How to Make Easy Korean Cucumber Salad Recipe

Step 1: Slice and salt the cucumbers

Wash the cucumbers and pat them dry. Slice them into thin rounds, about ⅛ inch thick. Place the slices in a bowl, sprinkle with 1 teaspoon kosher salt, and toss to coat evenly.

Let the salted cucumbers sit for 10 to 15 minutes. This step pulls out excess moisture and keeps the salad crunchy instead of watery. After resting, drain the cucumbers in a colander and gently squeeze by hand to remove extra liquid.

Step 2: Mix the dressing

In a small bowl, add gochugaru, soy sauce, rice vinegar, sugar, minced garlic, and toasted sesame oil. Stir until the sugar dissolves and the mixture looks smooth and glossy. Taste a tiny bit and adjust salt, sugar, or vinegar to match your preference.

Step 3: Toss everything together

Place the drained cucumbers back into a clean mixing bowl. Add the dressing, green onions, and sesame seeds. Toss gently with chopsticks or tongs until every slice looks coated with the spicy mixture.

Step 4: Chill and serve

Let the salad rest in the fridge for at least 10 minutes so the flavors sink into the cucumbers. Taste again before serving and adjust with a pinch of salt or a splash of vinegar if needed. Serve cold or slightly chilled.

Recipe Variations

Gluten free: Use tamari or coconut aminos instead of soy sauce.
Vegan: The base recipe already stays vegan; just keep your sugar choice vegan friendly if that matters to you.
Low carb: Swap sugar with a granular zero calorie sweetener that measures like sugar.
Extra crunchy: Add thinly sliced radish or carrot for more texture.
Nutty twist: Sprinkle crushed roasted peanuts or cashews on top before serving.
Extra spicy: Add a little gochujang along with the gochugaru for deeper heat and body.
Mild version: Cut the gochugaru in half and add more sesame seeds for flavor without strong heat.
Protein boost: Toss in chilled tofu cubes or sliced boiled egg on the side for a light meal.

Ways to Serve Easy Korean Cucumber Salad Recipe

Serve as a banchan side dish with Korean barbecue style meats and steamed rice.
Add to rice bowls with bulgogi, grilled chicken, or tofu for crunch and heat.
Pile inside lettuce wraps with rice and protein for a fresh bite.
Use as a topping for cold noodles or simple ramen to add brightness.
Serve alongside grilled fish or roasted vegetables for contrast.
Snack straight from the fridge when you crave something spicy and crunchy.

Storage Success

Store leftover Korean cucumber salad in an airtight container in the fridge. The cucumbers keep good texture for about 2 days, though they soften a bit after the first day. Stir before serving again, since some liquid collects at the bottom. If the flavor tastes mild after chilling, add a pinch of salt, a sprinkle of gochugaru, or a few drops of rice vinegar to wake it up.
