📝 About This Recipe

Experience the soul-soothing essence of Japanese home cooking with this authentic Miso Soup, a cornerstone of the 'Ichiju Sansai' dining tradition. This dairy-free delicacy balances a deeply savory dashi broth with the delicate, velvet-like texture of silken tofu and the mineral richness of rehydrated wakame seaweed. It is a masterclass in balance, offering a warm, probiotic-rich embrace that is both light enough for an appetizer and satisfying enough for a breakfast staple.

🥗 Ingredients

The Dashi Base (Stock)

  • 4 cups Water (filtered water is preferred for the cleanest flavor)
  • 1 piece Kombu (dried kelp, approximately 4x4 inches; do not wash off the white powder)
  • 2 cups Katsuobushi (tightly packed dried bonito flakes)

The Body

  • 1 block Silken Tofu (approx. 12-14 oz, drained and cut into 1/2 inch cubes)
  • 2 tablespoons Dried Wakame Seaweed (will expand significantly when hydrated)

The Miso Paste

  • 2 tablespoons White Miso Paste (Shiro Miso) (for a sweeter, milder profile)
  • 1 tablespoon Red Miso Paste (Aka Miso) (for a deeper, fermented punch)

Garnish & Aromatics

  • 2 stalks Green Onions (finely sliced on a bias)
  • 1/2 teaspoon Toasted Sesame Oil (optional, for a nutty aroma)
  • 1 pinch Shichimi Togarashi (Japanese seven-spice powder for a hint of heat)

👨‍🍳 Instructions

  1. 1

    Place the dried wakame seaweed in a small bowl of room temperature water and let it soak for 5-10 minutes until soft and expanded; drain and set aside.

  2. 2

    Gently wipe the kombu with a damp cloth to remove grit, but leave the white crystalline powder (mannitol) as it provides intense umami.

  3. 3

    In a medium saucepan, combine the 4 cups of water and the kombu. Heat over medium-low heat until the water just begins to simmer.

  4. 4

    Just before the water reaches a rolling boil, remove the kombu with tongs. Allowing it to boil will make the broth bitter and slimy.

  5. 5

    Increase the heat to medium-high. Once boiling, add the katsuobushi (bonito flakes) and let it boil for exactly 30 seconds.

  6. 6

    Turn off the heat and let the flakes sink to the bottom of the pot, which takes about 2-3 minutes; this ensures maximum flavor extraction without clouding the dashi.

  7. 7

    Strain the dashi through a fine-mesh sieve lined with cheesecloth into a clean pot, discarding the solids. You should have a clear, golden-hued liquid.

  8. 8

    Bring the clear dashi back to a very gentle simmer over medium heat.

  9. 9

    Carefully add the cubed silken tofu and the rehydrated wakame to the pot. Simmer for 1-2 minutes just until the tofu is heated through.

  10. 10

    Place the white and red miso pastes into a small ladle or bowl. Ladle about 1/2 cup of the hot dashi into the miso.

  11. 11

    Whisk the miso and dashi together with a small whisk or chopsticks until completely smooth and no clumps remain.

  12. 12

    Turn off the heat entirely. Pour the dissolved miso mixture back into the pot and stir gently to combine.

  13. 13

    Ladle the soup into individual bowls, ensuring everyone gets a generous portion of tofu and seaweed.

  14. 14

    Top with freshly sliced green onions and a tiny drop of toasted sesame oil if desired.

💡 Chef's Tips

Never boil the soup after adding the miso paste, as high heat destroys the delicate aromatics and beneficial probiotics. For a vegan version, replace the katsuobushi with 2-3 dried shiitake mushrooms soaked in the water overnight with the kombu. Use a 'miso strainer' or a simple ladle-and-whisk technique to ensure the paste dissolves perfectly without leaving salty clumps. Mixing different types of miso (Awase) creates a more complex and professional-grade flavor profile than using just one type. Silken tofu is traditional for its mouthfeel, but firm tofu can be used if you prefer a heartier, more structural bite.

🍽️ Serving Suggestions

Serve alongside a bowl of fluffy steamed short-grain white rice for a traditional Japanese breakfast. Pair with a piece of Salted Grilled Salmon (Shaké Shioyaki) for a complete protein-rich meal. Enjoy as a light starter before a main course of Vegetable Tempura or Sushi. Serve with a side of Tsukemono (Japanese pickled vegetables) to provide a crunchy, acidic contrast to the savory soup. Accompany with a hot cup of Genmaicha (brown rice green tea) to enhance the toasted, earthy notes of the miso.
