How to Make Korean Radish Soup (Kongnamul Daikon Tang) Recipe
Step 1: Prepare the Radish
Start by peeling the Korean radish and slicing it very thinly, then cut those slices into triangle shapes. This not only makes the pieces perfect for quick cooking but also gives your soup a beautiful visual appeal. The thin radish pieces will absorb all the delicious broth flavors wonderfully.
Step 2: Sauté the Radish
Heat 2 teaspoons of sesame oil in a pot over medium-high heat, then add the diced radish. Sauté for about 2 to 3 minutes until it becomes slightly translucent and starts to smell deliciously toasted. This step helps deepen the radish’s flavor before adding liquid.
Step 3: Add Green Onions for Aroma
Toss in the sliced green onions and continue sautéing for a few more minutes. This releases their signature fragrance, layering more complexity into your soup’s base that is inviting and fresh.
Step 4: Build the Broth
Now drop in the kombu piece, dried shiitake mushroom, and minced garlic, then pour in your 6 cups of water or vegetable broth. These ingredients work together to create a broth full of umami and earthy notes that are nothing short of magic.
Step 5: Simmer Until Tender
Bring everything to a gentle boil, then reduce the heat so it simmers quietly. Let it cook for about 12 to 15 minutes until the radish turns tender yet retains a slight bite, perfect for that satisfying spoonful.
Step 6: Season Perfectly
Stir in 1 to 2 tablespoons of gluten-free soy sauce along with 1 teaspoon of salt, tasting as you go to ensure it suits your palate. Let the soup simmer for an additional 3 minutes to allow all the flavors to marry beautifully.
Step 7: Serve with Love
Ladle the hot soup into bowls and sprinkle with optional sesame seeds, extra white pepper, and sliced green onions. These finishing touches brighten the dish and add texture and color to your comforting bowl of Korean Radish Soup (Kongnamul Daikon Tang) Recipe.

Side Dishes
This soup pairs beautifully with steamed rice and a variety of Korean banchan (side dishes), such as kimchi, seasoned spinach, or spicy cucumber salad. These sides offer vibrant flavors and textures that round out the meal and keep it exciting.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Place leftover soup in an airtight container and store it in the refrigerator for up to 3 days. The flavors actually deepen beautifully overnight, making it perfect for enjoying the next day.
Freezing
This soup freezes well for up to 2 months. Be sure to cool it completely before transferring to a freezer-safe container. When you’re ready, thaw overnight in the fridge for the best texture and flavor retention.
Reheating
Reheat gently on the stove over medium-low heat, stirring occasionally until warm throughout. Adding a splash of water or broth can help refresh the consistency, as radish can sometimes soak up liquid during refrigeration.
FAQs
