Basic Miso Soup Recipe

You would be hard-pressed to find a Japanese restaurant that does not have a Miso Soup somewhere on the menu, and any aficionado of Japanese cuisine will have tried it at one time or another.

Strictly speaking, a miso soup could be any soup given an umami boost with the addition of the Japanese fermented soy-bean paste known as ‘Miso’ but generally, the soup base is the rich sea-stock called Dashi, and typically only two or three other ingredients are included. The version pictured above simply includes a little Tofu, along with Scallions and Wakame seaweed.

Ingredient Notes

The soup base, or stock, is usually a Basic Dashi. In some cases, and in many Japanese homes, a bouillon powder, or ‘Instant Dashi’, may be used, but if you wish to prepare a Basic Miso Soup properly from scratch, you may follow the procedure set down in my Introduction to Dashi. For a Vegan, or vegetarian version, you can omit the use of Katsuobushi, and instead prepare a simple Kombu Dashi.

Miso comes in a variety of shades of color, with corresponding differences in taste, as well as saltiness. The lightest, sometimes referred to as ‘White Miso’, or ‘Shiro Miso’ is typically preferred for Miso Soup, and that is what is used here. The basic rule of thumb for a miso soup is about 3 tablespoons for every 4 cups of stock. I am just making enough for two people here and you may wish to double the recipe.

The Wakame Seaweed called for below can be fairly easily purchased in Asian grocery stores and comes packaged in dried strands which are easily reconstituted with just a few minutes soaking in water. If you prefer, you could easily replace this with julienne shreds of Spinach, or other leafy greens (although tougher ones should be blanched first).

The Method

Add the Dashi to a pot along with the white parts of the scallion and the tofu cubes. Bring it to a gentle simmer but do not allow it to boil as this will diminish the more delicate flavors of the dashi.

Put the miso in a small bowl and then scoop a small ladle full of the dashi over it and mix well before adding the contents back into the main pot. It is advisable to use this method as it is easier to mix the miso into the liquid this way. Again, do not allow the contents of the pot to boil.

Add the Wakame and allow everything to heat through gently. Finally, transfer to individual soup bowls and garnish with the green parts of the scallion.
