Oi Sobagi, Cucumber Kimchi : A Refreshing, Healthy Korean Side Dish
In the sweltering heat of summer or during a clean-eating kick, Oi Sobagi—spicy stuffed cucumber kimchi—becomes one of the most refreshing and nutritious Korean side dishes you can make. Crisp cucumbers filled with a savory and slightly spicy vegetable mixture provide a delightful crunch and burst of flavor with every bite. For many Koreans, Oi Sobagi is more than just a side dish—it’s a seasonal favorite and a nostalgic flavor of home.
Why Cucumbers Are a Dieter’s Best Friend
Cucumbers are made up of more than 95% water, making them a hydrating and low-calorie food ideal for weight management. Just one medium cucumber contains only about 16 calories! They’re also rich in antioxidants like beta-carotene and flavonoids, which help fight inflammation and oxidative stress. Cucumbers support digestion, flush out toxins, and provide a satisfying crunch that curbs cravings.
From a skin-health perspective, the silica in cucumbers helps improve skin elasticity and hydration. Additionally, the high fiber content (especially in the skin) supports gut health, which plays a major role in immunity and metabolism.
Ingredients for Oi Sobagi, Cucumber Kimchi (4-6 servings)
- 6–8 Korean cucumbers (or small seedless cucumbers)
- 1 tablespoon salt
- 1 small carrot, julienned
- 1/4 Korean radish (mu), julienned
- 3 green onions, chopped
- 1 tablespoon garlic, minced
- 1 teaspoon ginger, grated
- 2 tablespoons Korean red pepper flakes (gochugaru)
- 1 tablespoon fish sauce (optional)
- 1 teaspoon sugar
- 1 tablespoon salted shrimp (saeujeot) or 1 more tablespoon fish sauce (optional)
- 1/2 cup chives or garlic chives (buchu), chopped
How to Make Oi Sobagi – Step-by-Step
- Prep the cucumbers: Wash and trim both ends. Make a deep cross cut (not all the way through) at the center of each cucumber so they can open like a flower.
- Salt them: Sprinkle salt on the cuts and surface of the cucumbers. Let them sit for about 30 minutes to soften and release excess water. Rinse and drain.
- Prepare the stuffing: In a bowl, combine radish, carrot, green onion, chives, garlic, ginger, gochugaru, fish sauce, sugar, and salted shrimp. Mix well and let it sit for 10 minutes to meld the flavors.
- Stuff the cucumbers: Gently open each cucumber and fill them with the spicy vegetable mixture.
- Ferment: Place them in an airtight container. Let sit at room temperature for 1 day, then refrigerate. They’re best after 1–2 days in the fridge.
