This vegan miso soup uses kombu and shiitake dashi for rich, umami flavor - no bonito flakes needed. Easy, authentic, and ready in 15 minutes.
Rehydrate wakame
Add dried wakame to a bowl of cold water. Soak about 5 minutes, then rinse, squeeze out excess water, and cut into small pieces. Set aside.
Make the broth
Traditionally, kombu and shiitake are soaked in cold water for several hours before gently heating for the best flavor. For a quicker version, bring dried shiitake in water to a boil, reduce heat to simmer, add kombu, and continue to simmer for 10 minutes.
Prep add-ins
While the broth simmers, cube the soft tofu and finely slice the green onion.
Strain the dashi
Turn off the heat. Use tongs to remove the kombu and shiitake from the pot. (You can slice the mushrooms and add them back if you like.)
Add tofu and wakame
Stir in the tofu cubes and the rehydrated wakame. Let them warm through in the hot broth for about a minute.
Dissolve miso
Using a small fine-mesh strainer (or a ladle), dissolve the miso paste into the hot broth until smooth and fully incorporated.
Season
Add a small splash of Yondu (or low-sodium soy sauce/tamari) to season to taste.
Serve
Ladle into bowls and garnish with sliced green onion.
