Silken Tofu Miso Soup with Soft Mushrooms

An ultra-gentle, savory miso broth with silky tofu and tender mushrooms—light for lunch, but satisfying with high-protein comfort in every spoonful.

Ingredients

• 600 g silken tofu (2 blocks), cut into large soft cubes
• 200 g mushrooms (shiitake, cremini, or button), thinly sliced
• 4 cups (1 L) water
• 2 tsp dashi powder *(or use 4 cups low-sodium chicken broth as the base instead of water)*
• 4 tbsp white or yellow miso paste
• 2 tbsp soy sauce (or tamari)
• 2 tsp toasted sesame oil
• 2 green onions, thinly sliced (optional)

Method

• 1

  Step 1: Make the gentle broth

  In a medium saucepan, bring the water and dashi powder to a bare simmer over medium heat (small bubbles, not a rolling boil), about 3 minutes.

  Step 2: Soften the mushrooms

  Add mushrooms and simmer gently until very tender and silky-soft, 5–6 minutes. Keep the heat low so the broth stays clear and calm.

  Step 3: Warm the tofu (don’t boil)

  Slide in the silken tofu cubes. Nudge them gently with a spoon so they don’t break. Warm through at a bare simmer for 2 minutes.

  Step 4: Dissolve the miso properly

  Turn the heat to low (no bubbling). Scoop about 1/2 cup of hot broth into a bowl, whisk in the miso until smooth, then pour it back into the pot. *(This prevents graininess and preserves miso’s delicate flavor.)*

  Step 5: Season and finish

  Stir in soy sauce and sesame oil. Taste and adjust with a little more miso or soy if needed. Ladle into bowls and top with green onion if using.

Tips

• **Best mushrooms for “soft”**: Button/cremini get very tender quickly; shiitake adds deeper flavor—slice thin so they soften fast.
• **Don’t boil after adding miso**: High heat dulls miso flavor; keep it just warm with tiny wisps of steam.
• **Protein boost without heaviness**: Use the full 600 g tofu as written—this keeps the texture soft while meeting the high-protein target.
• **To serve**: Great as-is for a light lunch; if you have it, add a small side of plain rice (soft, not fried) for extra comfort.
