This traditional Japanese miso soup brings restaurant-quality comfort to your home with silky tofu, umami-rich dashi broth, and tender wakame seaweed. Simple yet deeply satisfying, this centuries-old recipe transforms just a handful of ingredients into pure liquid comfort that's perfect as an appetizer or light meal.
Make the dashi by bringing water to a boil with kombu and katsuobushi for 5 minutes.
Strain the dashi and return the clear broth to the pot.
In a small bowl, whisk miso paste with a few tablespoons of hot dashi until smooth.
Add cubed tofu and wakame seaweed to the dashi and simmer gently for 2-3 minutes.
Remove the pot from heat and slowly stir in the miso mixture.
Serve immediately, garnished with sliced green onions.
Notes
Never boil the soup after adding miso paste as it destroys beneficial probiotics and can make the soup grainyKombu can be reused 2-3 times for making dashi - store it in the refrigerator between usesFor vegetarian version, omit katsuobushi and use dried shiitake mushrooms for umami depthSoft or silken tofu works best as it won't break apart during cookingWakame should be rehydrated for only a few minutes as it expands considerablyStore leftover miso paste in the refrigerator for up to 1 year after openingFresh miso soup is best served immediately but can be gently reheated without boiling
