Miso Soup Fundamentals
The soul of this soup is the dashi. If you start with a strong, clear broth, the rest follows easily. It is meant to be a light, restorative bowl that wakes up the palate.
Keep the heat low
Your miso paste contains active cultures; boiling it turns the broth grainy and dull. Always add it at the very end with the heat off.

What goes in.
- 4 cupswater
- 1 piece (3-inch)dried kombu (kelp)
- 1 cupkatsuobushi (dried bonito flakes)
- 3 tbspmiso paste (red, white, or mixed)
- 1/2 cupsilken tofu, cut into 1/2-inch cubes
- 2 tbspgreen onions, thinly sliced
Tempering the paste
Whisk your miso with a splash of warm dashi in a small bowl until smooth before adding it to the pot. This prevents clumps and ensures even seasoning.
The method.
Prepare the dashi
Place water and kombu in the saucepan over medium heat. Remove the kombu just before the water hits a boil; if you leave it in, the broth becomes slimy.
Steep the bonito
Add the bonito flakes to the water, let it bubble for 30 seconds, then remove from heat. Let it steep for 5 minutes until the flakes sink to the bottom.
Strain
Pour the broth through a fine-mesh strainer into a clean pot, discarding the solids.
Simmer the solids
Bring the strained dashi back to a gentle simmer. Add the tofu cubes and cook for 1 minute.
Finish
Turn off the heat. Temper your miso paste as described in the technique callout, whisk it into the broth, and garnish with sliced green onions immediately.
Other turns to take.
Wakame Miso
Add one teaspoon of dried wakame seaweed to the dashi while it simmers to add texture.
Root Vegetable Miso
Add paper-thin slices of daikon radish or carrot to the dashi first and simmer until tender before adding the tofu.
When it doesn't go to plan.
If you are short on time, high-quality dashi granules stirred into boiling water are a reliable substitute for homemade stock.
Taste your miso before adding it all; different brands vary significantly in salt content.
Serve in shallow bowls so the ingredients remain visible rather than sinking to the bottom.

Can I reheat leftover miso soup?
You can, but do it slowly on the lowest heat setting. If it bubbles, the flavor profile changes and the miso can separate.
Which miso should I use?
White miso is sweet and mild, red miso is pungent and salty. Start with a white or 'awase' (mixed) miso for the most versatile flavor.
