Authentic Miso Soup
A comforting, umami-rich Japanese classic that brings the warmth of a traditional kitchen to your table in minutes.
Ingredients
- •4 cups water
- •1 piece (4-inch) dried kombu (kelp)
- •1/2 cup katsuobushi (dried bonito flakes) OR 1 tablespoon dashi powder
- •3 tablespoons white or yellow miso paste
- •1/2 block silken tofu, cut into 1/2-inch cubes
- •2 tablespoons thinly sliced green onions
- •1 teaspoon dried wakame seaweed
Instructions
- 1
Place the water and dried kombu in a medium pot and let it soak for 15 minutes to rehydrate.
- 2
Place the pot over medium heat and bring to a gentle simmer. Remove the kombu just before the water reaches a boil to prevent bitterness.
- 3
Add the katsuobushi flakes, turn off the heat, and let them steep for 5 minutes. If using dashi powder, simply stir it into the hot water now.
- 4
Strain the broth through a fine-mesh sieve into a clean pot, discarding the solids.
- 5
Add the dried wakame to the broth and simmer for 2 minutes until rehydrated, then add the tofu cubes and heat gently for another minute.
- 6
Place the miso paste into a small ladle or bowl, add a little bit of the hot broth, and whisk until smooth to prevent clumps.
- 7
Pour the miso mixture back into the pot, stir gently to combine, and remove from heat immediately to preserve the delicate miso flavor.
- 8
Ladle the soup into bowls and garnish with the sliced green onions.
💡 Chef tips
- Never boil the soup after adding the miso paste, as high heat destroys the beneficial probiotics and alters the delicate fermented flavor.
- For a vegetarian version, omit the bonito flakes and use a kombu-only dashi or a shiitake mushroom-based dashi.
- You can store leftover broth in the refrigerator for up to 3 days, but add the miso paste fresh each time you reheat a serving.
✅ How it should turn out
The finished soup should be clear and aromatic with a savory, salty-sweet depth, featuring tender tofu cubes and soft seaweed that melt in your mouth.
