Authentic Dashi Miso Soup

Miso soup made the right way — with a proper kombu and katsuobushi dashi that gives the broth a depth no instant stock can match, finished with silken tofu, wakame, and a whisked spoonful of white miso.

20 min4 servings

Ingredients

  • For the dashi: 1 L cold water, 15 g dried kombu, 20 g katsuobushi (bonito flakes)
  • For the soup: 3 tbsp white (shiro) miso paste, 200 g silken tofu, cut into 1.5 cm cubes, 10 g dried wakame seaweed, 2 spring onions, thinly sliced
  • Optional additions: shiitake mushrooms, clams, enoki mushrooms
Authentic Dashi Miso Soup

Instructions

  1. 1

    Make the dashi: place the kombu in the cold water and leave to soak for 30 minutes. This cold infusion extracts the clean, oceanic umami without bitterness.

  2. 2

    Place the pot over medium heat. Just before the water reaches a boil (small bubbles will appear at the edges), remove the kombu. Do not boil it — boiling makes the dashi bitter.

  3. 3

    Bring the dashi to a full boil. Add the katsuobushi, remove from heat immediately, and steep for 3 minutes. Strain through a fine sieve lined with a paper towel. The dashi should be a clear, pale amber.

  4. 4

    Soak the dried wakame in cold water for 5 minutes until rehydrated. Drain and squeeze gently.

  5. 5

    Return the dashi to a gentle simmer. Add the tofu cubes and wakame and warm through for 2 minutes. Do not boil after adding the miso.

  6. 6

    Place the miso paste in a small bowl. Ladle a little hot dashi over it and whisk until completely smooth. This prevents lumps. Pour the dissolved miso back into the pot and stir gently.

  7. 7

    Taste — the soup should be savoury, clean, and deeply umami. Add more miso if needed, but never boil after adding it as this destroys the flavour. Ladle into warm bowls and top with spring onions. Serve immediately.
