For 4 servings
- prep · ~5 min
Soak the wakame.
Place dried wakame in a small bowl of cold water and let it soak for 5 minutes until rehydrated and tender. Drain and set aside.
- boil · ~8 min
Make the kombu dashi.
Add 4 cups of water and the kombu piece to a medium saucepan. Place over medium heat and slowly bring to just below a boil. As soon as small bubbles appear around the edges, remove the kombu with tongs — do not let it boil.
TIPBoiling kombu makes the broth slimy and bitter. Pull it out the moment you see bubbles forming. - boil · ~2 min
Add bonito flakes and finish dashi.
Bring the kombu-infused water to a full boil. Add the bonito flakes all at once, then immediately turn off the heat. Let the flakes steep undisturbed for 2 minutes.
TIPDon't stir the bonito flakes — stirring makes the broth cloudy. Let them sink naturally. - prep · ~1 min
Strain the dashi.
Place a fine mesh strainer over a clean bowl. Pour the broth through the strainer to catch the bonito flakes. Return the clear dashi to the saucepan. Discard the spent flakes.
- simmer · ~2 min
Warm the tofu in the broth.
Place the saucepan with strained dashi over low heat. Gently add the cubed silken tofu and let it warm through for 2 minutes. The broth should be hot but not simmering.
TIPNever boil miso soup after adding miso. High heat destroys the delicate flavor and beneficial probiotics. - mix · ~1 min
Dissolve the miso paste.
Turn off the heat. Place the miso paste in a ladle, dip it into the hot broth, and whisk the miso with chopsticks inside the ladle until completely dissolved. Stir the dissolved miso back into the soup.
TIPDissolving miso in a ladle first prevents lumps and ensures even distribution. - assemble · ~1 min
Add wakame and finish.
Stir the rehydrated wakame into the soup. Taste and adjust with a pinch of salt if needed. Ladle into serving bowls immediately.
- garnish · ~1 min
Garnish with green onions and serve.
Top each bowl generously with sliced green onions. Serve hot as a starter or alongside rice for a light meal.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a fine-mesh strainer lined with cheesecloth for an extra-clear dashi broth.
- 2Cut the silken tofu gently with a wet knife to prevent sticking and crumbling.
- 3Rehydrate the wakame until just tender – oversoaking makes it mushy and flavorless.
- 4Always remove the kombu before the water boils to avoid a slimy, bitter broth.
- 5Never reheat leftover miso soup in the microwave; the miso's aroma will degrade.
- 6For the cleanest miso dissolution, whisk the paste in the ladle until no streaks remain before stirring in.
