Looking for a healthy, velvety-smooth, and intensely flavorful Korean side dish that you can whip up in minutes? If so, this recipe is a must-try. This innovative dish was featured on South Korea’s premier celebrity cooking show, KBS “Funstaurant” (Shin-sang-chul-si Pyeon-seu-to-rang), developed by the multitalented country singer and culinary genius Lee Chan-won. Known as the ultimate “rice thief” (bap-doduk), this Soft Tofu Jjabagi turns delicate silken tofu into a mouth-watering masterpiece using a special home-brewed flavored soy sauce.
Silken tofu (sundubu) is usually associated with piping-hot stews, but this dish serves it cold, bathed in a rich, sweet, and deeply aromatic soy sauce. Packed with healthy protein, extremely low in calories, and ridiculously simple to prepare, it is the perfect quick side dish for busy weeknights or a light, refreshing meal.

- Sugar: 4 tbsp
- Cheongju (Korean refined rice wine, or substitute with Mirin/Sake): 7 tbsp
- Corn Syrup (or Starch Syrup/Water-yeot): 2 tbsp

Step-by-Step Cooking Instructions
Step 1: Brew Chantto’s Special Flavored Soy Sauce
- In a small saucepan, combine 10 tablespoons of Jin soy sauce, 4 tablespoons of sugar, 7 tablespoons of Cheongju (or mirin), 2 tablespoons of corn syrup, and 10 tablespoons of water.
- Add the cut green onion stalk and 6 to 10 whole peeled garlic cloves.
- Bring the mixture to a boil over medium-high heat. Let it boil rapidly for exactly 5 minutes to draw out the deep umami sweetness from the aromatics and cook off the alcohol.
- Turn off the heat and let the sauce cool completely.
- Strain the mixture through a fine sieve to remove the green onion and garlic, leaving behind a perfectly smooth, rich, and glossy flavored soy sauce.
Step 2: Prep the Fresh Aromatics
- Finely mince the half onion and half handful of chives.
- Slice the green Cheongyang chili and red chili into very thin, delicate rings.
Step 3: Arrange the Silken Tofu (No Crushing!)
- Take your 3 packs of silken tofu and slice the packaging open. Gently slide the whole, intact tofu logs into a shallow airtight container side-by-side.
- Pro-Tip: Keeping the silken tofu completely whole and uncrushed is a key step! It preserves the beautiful, smooth texture and prevents it from turning soggy.
- Generously pile the minced onions, fresh chives, and sliced red and green chilies directly on top of the silken tofu logs.
Step 4: Dress and Chill
- Slowly pour the completely cooled flavored soy sauce over the tofu and vegetables, showering them evenly. The sauce should pool around the tofu, submerging the base beautifully (jjabagi style).
- Cover the container and refrigerate.
The Legendary Butter & Tofu Rice Bowl (How to Serve)
While you can dig in immediately, this dish enters a league of its own after 1 to 2 days of cold fermentation in the fridge. During this time, the silken tofu naturally expels excess water, becoming noticeably firmer, colder, and more velvety, while fully absorbing the rich sweet-savory flavor of the sauce.
To experience this dish like a true Korean culinary expert:
- Scoop a steaming bowl of fresh white rice.
- Drop one slice of butter into the hot rice and let it melt.
- Spoon a generous portion of the firm, cold silken tofu, fresh vegetables, and savory soy glaze right on top.
- Gently mix everything together. The buttery richness combines with the cold, sweet-savory tofu to create an incredibly smooth, comforting, and unforgettable bit
