Yield
Serves 4 generous portions
Difficulty Level
Easy – Perfect for all home cooks, no specialized equipment needed
Ingredients
- 4 cups cold dashi broth (kombu and bonito-based)
- 3 tablespoons white miso paste (shiro miso)
- 1/2 cup firm tofu, cut into 1/2-inch cubes
- 2 tablespoons chopped green onions (scallions)
- 1/4 cup wakame seaweed, soaked and drained
- 1 small cucumber, peeled and julienned

- Optional: thinly sliced shiso leaves or microgreens for freshness
Instructions
- Prepare the dashi broth: Start with cold dashi to preserve the subtle flavors and ensure the soup remains refreshing. You can use homemade dashi or a high-quality instant powder dissolved in cold water.
- Dissolve miso paste: In a medium bowl, take a few tablespoons of cold dashi broth and whisk in the white miso paste until smooth and lump-free.This prevents clumping and ensures even distribution of that signature umami.
- Combine broth and miso: Gently stir the miso mixture back into the remaining cold dashi broth. Avoid vigorous stirring to preserve the delicate flavors and prevent oxidation.
- Add tofu and wakame: Carefully fold in the cubed tofu and hydrated wakame seaweed. Thes ingredients contribute to the texture contrast and keep the soup light and nutrient-rich.
- Incorporate fresh vegetables: Add the julienned cucumber and chopped green onions for a refreshing crunch and bright flavor balance against the creamy miso base.
- Chill: refrigerate the soup for at least 30 minutes before serving, allowing the flavors to meld and the soup to reach an invigorating cold temperature.
- Garnish and serve: just before serving, sprinkle toasted sesame seeds and optional shiso leaves or microgreens on top for visual appeal and layered flavor.
Chef’s Notes
- Cold Miso Safety: Use pasteurized miso paste and keep the soup refrigerated to prevent bacterial growth. Cold miso soup holds best consumed within 24 hours.
- Flavor Variation: Try substituting white miso with red miso for a deeper, more robust flavor, but be mindful this can intensify the saltiness when chilled.

- Vegetarian/Vegan Option: Use kombu dashi without bonito flakes, and verify miso paste is vegan-friendly to suit dietary preferences.
