Recipe at a Glance
- Servings: 2
- Prep time: 5 minutes
- Cook time: 10 minutes
- Total time: 15 minutes
- Difficulty: Easy
Ingredients

- 500 ml (2 cups) dashi stock
- 2 tablespoons miso paste, plus more to taste
- 100 g (3.5 oz) soft or medium-firm tofu, cut into small cubes
- 1 teaspoon dried wakame
- 1 green onion, thinly sliced
Ingredient Substitutions
- Dashi: Use instant dashi for convenience. Kombu dashi makes the soup vegetarian or vegan.
- Miso: White miso is mild and slightly sweet; yellow or awase miso gives a stronger everyday flavor.
- Wakame: Replace it with spinach, mushrooms, daikon, or another quick-cooking vegetable.
- Tofu: Medium-firm tofu is easiest for beginners because it holds its shape.
How to Make Miso Soup
1. Heat the Dashi
Pour the dashi into a small saucepan and warm it over medium heat. Bring it just to a gentle simmer, not a rolling boil.

2. Add Tofu and Wakame
Add the tofu cubes and dried wakame. Simmer gently for 2–3 minutes, until the wakame expands and the tofu is heated through.

3. Dissolve the Miso
Reduce the heat to low. Place the miso in a ladle or small strainer, add a little hot dashi, and stir until smooth before mixing it into the soup.

4. Finish Without Boiling
Turn off the heat as soon as the miso is incorporated. Add the green onion, taste, and add a little more miso if needed. Serve immediately.

Tips for First-Time Cooks
- Never boil the soup after adding miso; high heat dulls its aroma.
- Start with less miso because saltiness varies by brand.
- Dissolve miso separately to prevent lumps.
- Add delicate green onion after turning off the heat.
Common Problems
The soup is too salty
Add more unsalted dashi or hot water. Next time, begin with less miso and adjust after tasting.
The miso is lumpy
Use a small strainer or dissolve it in a ladle with hot dashi before adding it to the saucepan.
The tofu broke apart
Use medium-firm tofu and stir gently after adding it.
Storage and Reheating
Refrigerate in an airtight container for up to 2 days. Reheat gently and stop before boiling. The flavor and aroma are best immediately after cooking. Freezing is not recommended for tofu-based miso soup.
Frequently Asked Questions
Which miso is best for beginners?
White or awase miso is approachable and easy to balance. Taste before adding the full amount.
Is miso soup vegetarian?
Traditional dashi often contains bonito fish. Use kombu or shiitake dashi and check the miso label for a vegetarian or vegan version.
Can I add other vegetables?
Yes. Mushrooms, spinach, daikon, potato, cabbage, and aburaage are common additions. Cook firm vegetables in the dashi before adding miso.
Why This Miso Soup Recipe Works
The short ingredient list keeps each flavor clear, while dissolving the miso separately prevents lumps. Gentle heat protects the fresh aroma of the miso and keeps the tofu intact, making this a reliable first recipe for Japanese home cooking.
Serving Ideas
Serve miso soup alongside steamed rice, grilled fish, tamagoyaki, or a simple vegetable side dish. For breakfast, keep the flavors light; for dinner, add mushrooms, daikon, or potato to make the bowl more substantial without complicating the method.
