Essential Ingredients for a Deep, Authentic Flavor
The core of this soup lies in high-quality siraegi, savory doenjang, and the flavor-enhancing perilla seed powder. Prepare your ingredients carefully to achieve the perfect balance of taste.
Main and Secondary Ingredients
- Boiled Siraegi (Radish Greens): 300g (Make sure they are boiled until very tender. If the stems feel a bit tough, gently peeling the thin outer skin will yield a much softer texture.)
- Julienned Onion: 1/2 onion (Adds a subtle, natural sweetness to the broth.)
- Minced Green Onion: 1 stalk (Provides the refreshing foundational flavor of the soup.)
- Green and Red Chili Peppers: 1~2 peppers (If you prefer a spicy kick, substituting with Cheongyang chili peppers is highly recommended.)
- Rice Water (Ssal-tteu-mul): Approximately 3 Liters (Using the milky water from washing rice instead of plain water adds starch, making the broth significantly smoother, thicker, and more robust.)
The Golden Ratio Seasoning Paste
- Doenjang (Soybean Paste): 3 tablespoons (Since the saltiness of doenjang varies by household, mixing homemade doenjang with a commercial brand creates a more balanced flavor.)
- Gochujang (Red Chili Paste): 1 tablespoon (Cuts through the potential heaviness of doenjang and adds a beautiful, deep color.)
- Soup Soy Sauce (Guk-ganjang): 2 tablespoons (Fills in any missing umami and adjusts the overall saltiness.)
- Minced Garlic: 1 tablespoon (An indispensable aromatic in Korean cuisine.)
- Sugar: 1 teaspoon (This is the secret ingredient that perfectly neutralizes the characteristic bitterness and stale odor of the radish greens.)
- Perilla Seed Powder: 6 tablespoons total (Mix 5 tablespoons into the marinade, and reserve 1 tablespoon to sprinkle as a garnish at the end.)
- Perilla Oil: 2 tablespoons (Used for sautéing the siraegi to maximize its nutty aroma.)
- Black Pepper: A pinch (Just a few taps to refine the flavor profile.)
- Red Chili Powder (Gochugaru): 1/2 tablespoon (Used at the very end when you want to add a spicy, sharp charm.)

Step-by-Step Cooking Instructions
In soup making, heat control and the order of preparation are paramount. Follow these steps sequentially to extract the deepest possible flavors.
1. Prepping and Chopping the Ingredients
First, you need to prep the prepared siraegi and vegetables into bite-sized pieces. Squeeze the excess water from the tender-boiled siraegi lightly, and chop it roughly into 5cm (2-inch) lengths so it’s easy to eat with a spoon. Slice the onion thinly so its sweetness can easily infuse the broth, and finely chop the green onion to release its aroma. Slice the chili peppers diagonally and set them aside to add a spicy accent at the end.
2. Marinating the Siraegi (Crucial Step)
The secret to great siraegi dishes is ensuring the greens and the broth are harmoniously unified, rather than tasting separate. Prepare a large mixing bowl and add the chopped siraegi (300g), julienned onion, minced green onion, and minced garlic (1 tbsp). Next, add the doenjang (3 tbsp), gochujang (1 tbsp), soup soy sauce (2 tbsp), sugar (1 tsp), and the star ingredient, perilla seed powder (5 tbsp). Use your hands to mix and knead everything together firmly.
- Cooking Tip: Adding a small amount of sugar neutralizes any grassy or earthy smells from the siraegi and elevates a subtle umami. Letting this mixture marinate for about 10 minutes allows the flavors to penetrate deeply into the fibers. However, since this is a long-simmering stew, you can proceed to cook immediately if you are short on time.
3. Sautéing with Perilla Oil for Nutty Aroma
Now, turn on the stove and place a heavy-bottomed pot over the heat. Drizzle the perilla oil (2 tbsp) into the pot and pour in the fully marinated siraegi. To prevent the seasoning from sticking and burning at the bottom, add just 1 cup of the prepared rice water (or broth) first. Sauté over medium heat until the siraegi becomes noticeably softer and relaxed. As you sauté, the rich nuttiness of the perilla oil and the fermented aroma of the doenjang will combine, filling your kitchen with a mouth-watering fragrance.
4. Pouring the Broth and Simmering Patiently
Once the siraegi is coated in oil and well-sautéed, pour all the remaining rice water (about 3 Liters) into the pot. Siraegi soup is not a quick-boil dish; the longer you simmer it, the more the sweet and deep essences are extracted from the ingredients, which is why starting with a generous amount of liquid is essential.
Initially, bring it to a rolling boil over high heat. Once the entire pot is bubbling, cover it with a lid and reduce the heat to medium-low. Allow it to simmer patiently for at least 30 minutes until the siraegi becomes completely mushy, tender, and melt-in-your-mouth soft.
5. Final Seasoning and Plating
After simmering with care for a long time, the volume of the broth will have reduced perfectly, and its color will have deepened into a rich brown. If you fish out a piece of siraegi and it dissolves softly in your mouth, the soup is practically done.
At this stage, add the diagonally sliced chili peppers to introduce a refreshing, spicy kick. Taste the broth overall and adjust any lacking seasoning with a sprinkle of salt or soup soy sauce. Since the saltiness of doenjang varies in every home, it is vital to check the final seasoning before turning off the heat.

Chef's Tips to Enjoy It 200% More
While this carefully crafted Radish Greens and Perilla Seed Soybean Paste Soup is flawless on its own, adding a few details when serving can make it feel like a premium restaurant meal.
The Collaboration of Spice and Nutty Richness
After ladling a generous serving into an individual soup bowl, try adding half a tablespoon of red chili powder and the remaining 1 tablespoon of perilla seed powder as a garnish on top. When you stir it at the dining table, the intense nuttiness of the perilla seeds and the pleasant heat of the chili powder spread out, making every single bite a moment of admiration.
The Magic of Broth: Using Beef Bone Broth (Sagol)
As guided in the recipe, using pure rice water creates a wonderfully clean and savory taste. However, if you desire a heavier, rich meat-based flavor profile, try replacing half of the rice water with commercial beef bone broth (sagol) or rich bone broth sold at local butchers. This will result in a premium soybean paste soup with exceptional body and depth.
