Miso Soup
A gentle, nourishing bowl of dashi broth enriched with savory miso paste, silky tofu, and ribbons of wakame seaweed. This is the everyday Japanese soup that comes together in minutes once your dashi is ready.

Method
Soak the kombu: Place the kombu in a medium saucepan with the 4 cups of water and let it soak for 10 minutes if you have time. This gentle soak begins drawing out the kombu's deep, savory flavor for your dashi.
Heat the kombu slowly: Set the pan over medium-low heat and warm the water gradually, aiming to reach a bare simmer over about 10 minutes. Slow heating extracts the most umami without turning the broth bitter.
Remove the kombu: Just before the water reaches a boil, lift out the kombu and discard it (or save it for another use). Boiling the kombu makes the dashi slimy and bitter, so timing here matters.
Add the bonito: Bring the liquid to a brief boil, then turn off the heat and immediately add the bonito flakes. Let them steep undisturbed for 5 minutes as they sink and infuse the broth with smoky depth.
Strain the dashi: Pour the broth through a fine-mesh strainer set over a clean pot, gently pressing the bonito flakes to release the last of the liquid. You now have classic awase dashi, the backbone of the soup.
Rehydrate the wakame: While the dashi steeps, place the dried wakame in a small bowl of cool water for about 5 minutes until it softens and expands. Drain it well and set it aside.
Warm the tofu and mushrooms: Return the strained dashi to a gentle simmer over medium heat, then slide in the cubed tofu, the mushrooms, and the sliced aburaage if using. Let them heat through for 2 to 3 minutes, keeping the broth below a hard boil so the tofu stays intact.
Dissolve the miso: Place the miso paste in a small ladle or bowl, add a few spoonfuls of the hot dashi, and whisk until completely smooth. Dissolving it separately prevents lumps in the finished soup.
Add the miso to the pot: Lower the heat so the broth is no longer simmering, then stir the dissolved miso into the pot. Never let the soup boil after adding miso, because boiling dulls its flavor and aroma.
Add the wakame: Stir in the drained wakame and let everything warm together for about 1 minute. Taste and add a little more miso if you prefer a stronger flavor.
Serve: Ladle the soup into bowls, distributing the tofu and wakame evenly. Top each bowl with sliced scallions and serve hot right away.
Chef's tips
- Never boil the soup after adding miso; keep it just below a simmer to preserve the paste's fragrant, savory character.
- For a fast shortcut, replace the kombu and bonito with 1 teaspoon of dashi powder dissolved in the water, though homemade dashi tastes noticeably cleaner.
- White (shiro) miso is milder and slightly sweet while red (aka) miso is bolder and saltier, so start with less and adjust to your taste.
Cooking times vary by equipment -- cook to temperature and to taste.
