How to make porcini miso soup

Soak the dried porcini mushrooms in the hot water 20-30 minutes until softened.


Remove the mushrooms, slice if needed, and keep the soaking liquid for the broth.
In a pot, combine the porcini soaking liquid with the white miso paste, stirring until smooth.
Add the grated garlic, grated ginger, and soy sauce if using.
Bring the broth to a gentle simmer, then add the porcini mushrooms.
Cook the rice noodles or soba noodles separately, then divide them into bowls.
Add the baby spinach, chopped chives or scallions, and red pepper flakes or fresh chili to the broth. Cook briefly until the spinach just wilts.


Pour the hot porcini miso broth over the noodles and serve immediately.

Serving tip

This miso porcini noodle soup is best served hot, with extra chives, scallions, or chili on top for a fresh finish. For a deeper flavor, use a little extra porcini soaking liquid in the broth.
