Heat the dashi or water in a pot over medium heat until it is warm but not boiling.

Add your chosen ingredients, such as tofu, green onion, or wakame seaweed, to the pot.

Simmer gently for a few minutes until the ingredients are heated through.
Turn off the heat to prevent boiling, which can affect the flavor of the miso.
Dissolve the miso paste in a ladle or small bowl with some of the hot dashi, then stir it back into the pot.
Taste and adjust the seasoning as needed.
Always dissolve miso paste separately before adding it to the soup to ensure even distribution.
Avoid boiling the soup after adding miso, as it can alter the flavor and reduce its nutritional benefits.
Experiment with different types of miso, such as white, yellow, or red, to discover your preferred flavor profile.
What is dashi, and can I substitute it?
Dashi is a Japanese soup stock made from ingredients like kombu (kelp) and bonito flakes. If you don’t have dashi, you can use plain water, but the flavor will be less authentic.
How do I store leftover miso soup?
Store leftover miso soup in an airtight container in the refrigerator for up to 2 days. Reheat gently without boiling.
Can I make miso soup vegan?
Yes, use kombu-based dashi and avoid adding non-vegan ingredients like bonito flakes or fish-based dashi.
What are some other ingredients I can add to miso soup?
You can add mushrooms, spinach, carrots, daikon radish, or even clams for variety.
How do I know how much miso to use?
As a general rule, use 1 tablespoon of miso for every 200 mL of dashi or water. Adjust to taste based on the saltiness of your miso.
