Why This Recipe Works (Quick Science)
The miso paste brings umami — that deep, savory flavor — because it’s fermented. Dashi is the base that gives miso soup its signature taste. Wakame expands and softens in water, and tofu soaks up the broth flavors. It’s light but still satisfying.
Common Mistakes
- Boiling the miso paste: High heat kills the good stuff in miso. Add it after turning off the heat.
- Using too much wakame: A little goes a long way! It expands a lot.
- Skipping the dashi: Miso soup without dashi just tastes flat.
- Not using soft tofu: Firm tofu doesn’t soak up flavor the same way.
What to Serve With
- Steamed rice
- Grilled salmon
- Japanese pickles
- Gyoza (dumplings)
- Edamame
FAQ
Can I use vegetable broth instead of dashi?
Yes, but it won’t taste quite as traditional. Dashi gives that authentic umami.
Is miso soup vegan?
Not usually, because dashi often contains fish. Use kombu dashi (kelp) for a vegan version.
Can I use firm tofu?
Yes, but soft or silken tofu has a better texture for soup.
Where do I find wakame?
Most Asian markets carry it. You can also buy it online.
Tools Needed
- Medium pot
- Wooden spoon or silicone spatula
- Sharp knife
- Cutting board
- Small bowls for ingredients
Substitutions and Variations
- No tofu? Use mushrooms instead
- No wakame? Try spinach or bok choy
- Spicy version: Add a touch of chili oil
- Richer flavor: Add a splash of soy sauce
Make Ahead Tips
- You can pre-slice the tofu and green onions and store them in the fridge
- Rehydrate the wakame ahead and store in water (change water before using)
- Don’t mix in the miso paste until you’re ready to eat — do it fresh
How to Make Miso Soup with Tofu and Seaweed
Step 1: Boil Water with Dashi
Pour 4 cups of water into a medium pot and add 1 teaspoon dashi granules. Bring to a gentle boil over medium heat.

Step 2: Add Wakame
Once the water is boiling, reduce to a simmer and stir in 2 tablespoons dried wakame seaweed. Let it simmer for 2–3 minutes until rehydrated and soft.

Step 3: Add Tofu
Gently add 1/2 block soft tofu (cut into small cubes) to the pot. Let it warm through for about 2 minutes. Don’t stir too much — tofu is delicate.

Step 4: Stir in Miso Paste
Turn off the heat. In a small bowl, dissolve 2 tablespoons miso paste with a few spoonfuls of the hot broth, then stir that mixture back into the pot. Stir gently until combined.

Step 5: Add Green Onions and Serve
Add 2 thinly sliced green onions. Give it a gentle stir. Ladle into bowls and serve hot.

Leftovers and Storage
- Store in an airtight container in the fridge for up to 2 days
- Reheat gently over low heat — don’t boil
- Don’t freeze — the tofu changes texture and miso can separate
