Umami Magical Mushroom Tofu Soup
Another rainy spring day here in the PNW. As I always say, April, May, and June bring July and August flowers. I made this soup with my own homemade dashi broth, inspired by my favorite restaurant, Nuka, on Maui in Hawaii.
This low-acid umami mushroom miso soup is a delightful blend of earthy mushrooms and rich miso, offering a savory and satisfying flavor profile. The miso base not only enhances the umami taste but also provides beneficial probiotics, which support gut health. Delicious!

Umami Magical Mushroom Tofu Soup
Yield: 2
Ingredients
- 4 cups water
- Kombu, about 4 to 6 inches
- 1 cup firm tofu, small cubes
- 1 cup sliced shiitake mushrooms
- 2 tablespoons miso paste (white)
- 2 sheets nori seaweed, sliced into strips
- Salt, to taste
- Cooked rice or rice noodles, for serving
- Optional toppings: sesame seeds
Instructions
- Combine kombu with water, simmer for 30 mins, then add bonito flakes, simmer for 10 mins, and strain. Alternatively, follow package instructions for instant dashi.
- In a pot, bring the dashi stock to a gentle simmer over medium heat.
- Once the stock is simmering, add cubed tofu and sliced shiitake mushrooms. Cook for 5-6 minutes until mushrooms are tender and tofu is heated through.
- In a small bowl, dissolve miso paste in a ladleful of the hot dashi stock, stirring until fully incorporated.
- Pour the dissolved miso paste into the soup pot, stirring gently to combine. Avoid boiling the soup after adding miso to preserve its flavor.
- Taste the soup and adjust seasoning with salt if necessary. Keep in mind that miso paste adds saltiness to the soup.
- Just before serving, add sliced nori seaweed to the soup and stir gently to distribute evenly.
