Miso Shiitake Soba Soup
Prep time
Cook time
Total time
A simple homemade dashi is the base of this healing, warming miso soup. Tofu & soba noodles make it hearty enough for a full meal.
Recipe type: Soup, main dish
Serves: 2 as a main, 4 as a starter
For the dashi:
  • A piece of dried kombu, about 2x3 inches
  • 4 cups water
For the miso soup:
  • 4 cups dashi
  • ½ cup sliced shiitake mushrooms
  • 3-4 tablespoons white or shiro miso
  • 1 teaspoon grated ginger
  • ¼ cup chopped scallions
  • ½ cup tofu cubes (firm tofu)
  • 4 baby bok choy pieces, coarse stalks thinly sliced
  • 6 oz. soba noodles, cooked separately (see notes)
  • Optional: a few teaspoons soy sauce or tamari
Serve with:
  • Shichimi or a pinch of chile flakes (optional)
  • Sprinkling of bonito flakes (optional)
  • ponzu, on the side
  1. Make the dashi: gently rinse the kombu piece. Place it in a medium pot with 4 cups water. Gently simmer for 10 minutes. Don’t let it boil, or the kombu flavor will turn bitter. Once the kombu piece is soft, remove it and bring the water to a boil for just a few minutes.
  2. Reduce heat again and add in ½ cup more water. In a small bowl, stir the miso paste together with some of the hot dashi water (until it’s not clumpy), then stir to incorporate it into the soup broth.
  3. Add the ginger, scallions, and shiitakes, and gently simmer for about 10 minutes to cook the mushrooms (Note: If your soup is getting too thick add more water until it is a thinner consistency).
  4. In the last few minutes of cooking time, add the tofu and bok choy. Taste and adjust seasonings to your liking. Remove from heat once the bok choy is wilted but still has some bite. Add the cooked soba noodles.
  5. Top with shichimi and bonito flakes, (both optional), and serve with ponzu or extra soy sauce on the side.
Note: some miso pastes can be saltier than others, start by adding less and add more to taste. If you over-salt, add more water.

I used these Eden Soba noodles. I don't prefer the kind that's 100% buckwheat (it gets clumpy). If you're gluten-free, I recommend using King Soba's brown rice noodles Jovial's brown rice pasta or Tinkyada's brown rice noodles.
