What You’ll Need

• 6–8 small Persian or Kirby cucumbers (or 3–4 small Korean cucumbers)
• 1 tablespoon kosher salt (for salting the cucumbers)
• 2–3 tablespoons gochugaru (Korean red pepper flakes; adjust to taste)
• 2 cloves garlic, finely minced
• 1 teaspoon fresh ginger, finely grated (optional but great)
• 2 green onions, thinly sliced
• 1 tablespoon fish sauce (or soy sauce for a vegetarian option)
• 1 tablespoon rice vinegar
• 1–2 teaspoons sugar or honey (to balance the heat)
• 1–2 teaspoons toasted sesame oil
• 1 tablespoon toasted sesame seeds
• Optional add-ins: 1 small carrot (julienned), 1/4 small onion (thinly sliced), chives, or perilla leaves

Step-by-Step Instructions

1. Prep the cucumbers: Wash and pat dry. Cut into 1/2-inch thick rounds or halve lengthwise and slice into half-moons. If the cucumbers are large, scoop out some seeds to keep things crisp.
2. Salt to draw out water: Toss cucumbers with 1 tablespoon kosher salt in a bowl.Let sit 15–20 minutes, tossing once. This step keeps them crunchy and helps them absorb flavor.
3. Rinse and dry: Rinse the cucumbers quickly under cold water to remove excess salt. Drain well and gently pat dry.You want them damp, not wet.
4. Make the seasoning: In a clean bowl, mix gochugaru, garlic, ginger, fish sauce, rice vinegar, sugar or honey, sesame oil, and sesame seeds. Adjust heat, salt, and sweetness to your liking.
5. Add aromatics: Stir in green onions and any optional add-ins like carrot or onion for extra crunch and color.
6. Toss to coat: Add cucumbers to the seasoning and gently toss until every piece is evenly coated. Taste and tweak seasoning more vinegar for brightness, more sugar for balance, or more gochugaru for heat.
7. Chill briefly (optional): For the best texture and flavor, chill 15–30 minutes.You can also eat it right away if you’re in a hurry.
8. Serve: Plate with an extra sprinkle of sesame seeds. It’s great alongside rice, grilled meats, noodles, or eggs.

Keeping It Fresh

FAQ

Is this fermented kimchi?

No. This is a quick kimchi meant to be eaten right away or within a few days. It has fresh, bright flavors rather than deep fermented tang.

Can I let it sit longer for more tang?

Yes, but keep it refrigerated. After a day or two, it will develop a slight tang as it sits, though cucumbers will soften over time.

What cucumbers work best?

Persian, Kirby, or Korean cucumbers are ideal because they’re small, firm, and not too seedy. If using larger cucumbers, scoop out the seeds to preserve crunch.

How spicy is it?

It’s medium by default. Start with 2 tablespoons of gochugaru and add more to taste. You can also mix in a pinch of sugar to soften the heat.

Can I make it ahead?

Absolutely. Make it the morning of or the day before serving. Store chilled, then toss before serving to redistribute the seasoning.

What if I don’t have fish sauce?

Use soy sauce or tamari and add a touch more garlic or a pinch of salt. A bit of miso whisked into the seasoning can also add savory depth.

Why is there liquid at the bottom?

Salt pulls water from the cucumbers, creating a seasoned brine. This is normal. Just stir before serving to coat everything evenly.

This quick cucumber kimchi brings bold flavor and satisfying crunch with minimal effort. It’s flexible, fast, and easy to love perfect for busy nights or brightening any meal. Keep a batch in the fridge, and you’ll always have a fresh, spicy side ready to go.
