A Spring Ritual, Written in My DNA
Every spring, my mom would make this cubed cucumber kimchi and something in my DNA still remembers it. The moment the season turns, I find myself craving it before I even realize why. One bowl of rice, this kimchi, nothing else. That was enough. That was everything.

What Is Cubed Cucumber Kimchi?
Cubed cucumber kimchi is called oi kkakdugi (오이 깍두기) in Korean. The word kkakdugi refers specifically to a cube-cut style of kimchi, most famously made with radish. Applied to cucumber, it creates a lighter, faster version that captures the same bold kimchi flavor in a fraction of the time. This is a distinctly different dish from regular oi kimchi, which is usually made with sliced or stuffed cucumbers. The cube cut is what makes this korean cucumber side dish so special, each piece stays crispy and juicy.

Oi Kkakdugi vs. Oi Kimchi: What’s the Difference?
Both are cucumber kimchi but the cut changes everything. Regular oi kimchi is typically made with half-moon slices, coins and cylinder shapes stuffed with vegetables, called oi sobagi. Cubed cucumber kimchi is different. You cut it chunky, toss it in the paste, and you’re done. No careful slicing, no stuffing, no fuss, just bold, crispy, juicy bites. It’s honestly the easiest kimchi recipe you can make with cucumber.
Why This Quick Kimchi Recipe Skips Long Fermentation
This is a quick cucumber kimchi you can serve the same day. While traditional napa cabbage kimchi ferments for weeks or even months, cucumber kimchi is meant to be eaten fresh and this cubed cucumber kimchi is at its absolute best within two days.

Why This Korean Cucumber Side Dish Is a Wellness Win
Cucumber is 95% water, naturally low in calories, and rich in vitamin K and C. Its high water content also makes it one of the best foods for skin hydration. Combined with gochugaru, which contains capsaicin, linked to metabolism and circulation support, and maesil cheong (Korean green plum syrup, a traditional digestive aid), it’s easy to see why this cubed cucumber kimchi earns its place as a wellness banchan.
The anchovy fish sauce adds umami while providing naturally occurring amino acids. The garlic adds a prebiotic boost. Every ingredient in this quick kimchi recipe has a reason to be there.

For the Kimchi Paste
Optional Toppings



Substitutions
- Maesil cheong: A small drizzle of honey plus a few drops of lemon juice works.
- Anchovy fish sauce: Any fish sauce you have or soy sauce as a vegan swap.
- Green onion → Buchu (garlic chives) : Green onion is the substitute here. The original recipe calls for Buchu (garlic chives), which is harder to find outside Korea. If you can get your hands on it, use buchu, cut into 2–3 cm lengths.

How to Make Cubed Cucumber Kimchi
Step 1. Wash and Prep the Cucumber
Wash the cucumbe. If it has prickles, scrub the skin with coarse salt or scrape with a knife. Cut off both ends.
Step 2. Cut Into Cubes and Salt
Divide the cucumber into 3 equal sections. Halve each section lengthwise and scoop out the seeds with a spoon. Cut each half into bite-sized cubes, roughly 2 cm (¾ inch). Add to a bowl, toss with coarse sea salt and sugar, and set aside for 20 minutes.


Step 3. Prep the Aromatics While You Wait
Finely slice the green onion and mince the garlic. Because we’re using green onion in place of Buchu, cutting it small is key.


Step 4. Coat With Gochugaru First
Drain and discard the liquid the cucumber has released. Do not rinse. Transfer the cubes to a mixing bowl. Add the gochugaru first and toss until every cube is evenly coated.
Step 5. Add Seasonings and Fold In Green Onion
Add the minced garlic, maesil cheong, and anchovy fish sauce. Toss everything together until well combined. Finally, add the sliced green onion and fold in gently.


Step 6. Finish and Serve
Scatter sesame seeds and sliced red chili on top. Serve immediately for maximum crunch, or leave it at room temperature for 2 hours before refrigerating. The flavors settle and deepen beautifully overnight.
