What is your favorite summer kimchi? Oi sobagi (오이소박이), stuffed cucumber kimchi, is a summer favorite in Korea. It’s crisp, crunchy and deliciously refreshing! Oi means cucumber, and sobagi means it’s stuffed with a seasoning mix. This oi sobagi recipe was originally posted in August 2012. I’ve updated it here with minor changes to the recipe and new photos.  

What type of cucumbers to use

Needless to say, oi sobagi is best made in the summer when cucumbers are in their peak season. I usually make it with Korean cucumbers whenever I can find them. They are long and slender with thin whitish/pale green skin. The flesh is thick, but less seedy than other cucumbers. I love how crisp, juicy, and sweet they are!

When Korean cucumbers are not available, Kirby (aka pickling) cucumbers are the next best thing to use. Always look for cucumbers that are firm and slender.

How to make oi sobagi

As is the case with most kimchi varieties, you’ll need to salt the cucumbers first. I use boiling hot salted water. Don’t worry, the hot water won’t cook the cucumbers. This is the method traditionally used for Korean pickled cucumbers, called oiji, to keep the cucumbers crisp and crunchy for a long time.

Then, make a pocket in the middle by making slits to create 4 cucumber spears that are held together at the end. Traditionally, both ends are left intact, which I prefer. Some people cut straight through one end, only keeping the other end intact. The latter will be easier, if that’s what you want.

I make slits after the cucumbers are salted so as not to lose the flavor in the water during the salting process. However, the salting process will go faster if you cut them before salting.

For the stuffing, buchu (garlic chives) is classic. I also added some Korean radish in this recipe, but you can substitute with onions or simply use more garlic chives. If you can’t find garlic chives, you can use scallions instead.

This cucumber kimchi can be eaten right away but will taste better after a day or two in the fridge. This is a quick kimchi not intended for several weeks of storage.

Hope you get a chance to make this easy and refreshing summer kimchi before the summer is over! It will be excellent with your Korean BBQ!

  • Add 6 cups of water with 1/2 cup of salt in a medium size pot. Bring it to a boil. Turn the heat off. Pour the boiling water over the cucumbers in a bowl. Keep the cucumbers submerged by weighing them down with a bowl or plate. Let it sit until the cucumbers are bendable, about an hour or two, depending on your cucumbers and salt.

  • Drain the cucumbers. Holding the top end of the cucumber on the cutting board, run a small knife through the middle lengthwise. Leave 1/2 inch uncut at both ends. Turn the cucumber and make another cut through the middle lengthwise to make a cross cut, again leaving 1/2 inch uncut at both ends.  Repeat with all the cucumbers.

  • Gently open each slit and insert about a teaspoonful or two of the stuffing. Be sure to fill all 4 slits of each cucumber. Repeat until all the cucumbers are stuffed. Place them in a jar or an airtight container. Leave it out at room temperature for a day. Then, store in the fridge.
