For the Mushroom Broth:

  • 1 oz dried porcini mushrooms (or shiitakes)
  • 3.5 tbsp white miso paste (non-gmo)
  • 5 cups hot water
  • 2-3 tbsp Tamari sauce or Coco Aminos (Optional, leave out for a low sodium diet)
  • 2 cloves garlic -grated
  • 1 tbsp fresh ginger root -grated

Add Ins:

  • 2 cups wild mushrooms
  • 2 cups baby spinach or (bok choy)
  • 1/3 cup fresh chives or scallions -chopped
  • 1/4 cup cilantro leaves -for garnish
  • 1 tsp red pepper flakes or fresh chili pepper to taste
  • 12 oz soba noodles


  • Place the dried porcini mushroom in a medium sized bowl and cover with the hot water. Allow it to sit for 30 minutes. Strain into a saucepan and reserve the mushrooms for another recipe or to add back into your noodle bowl when serving.
  • Bring the mushroom broth to a gentle simmer and stir in the wild mushrooms, garlic and ginger. Simmer for a couple of minute and remove from heat. 
  • In a separate bowl whisk together the miso paste with a ladle of the hot broth. Once incorporated add it to the pot with the soup together with the tamari or coco aminos.
  • Meanwhile cook the soba noodles in a separate pot until al dente. Mine take less than 4 minutes to be done just right. Drain and rinse well. (Do not cook the noodles in the mushroom broth as they contain lots of starches that will cloud the broth and throw off its flavor).
  • Divide the noodles between 4 bowls and top each with some of the baby spinach. Ladle the mushroom soup with the mushrooms on top and garnish with the cilantro, chives and chili pepper to taste. Serve hot.

  • Add Ins - thinly sliced vegetables, cubed tofu, edamame, blanched bok choy instead of spinach, nori or sprouts and go for udon or ramen noodles instead of the soba.
  • For an extra umami flavor make sure to add a strip of kombu when making the broth. The flavor is amazing!
