Miso Soup

4 1/4 cups water
4 oz extra firm tofu, diced
.5 oz bonito flakes
2 2-inch squares kombu
1/4 cup miso paste* dissolved in an equal amount of water
3/4 cup baby bok choy or seaweed cut into manageable strips

At no point do you want the water/soup to come to a full boil. Watch your soup carefully. Simmer kombu in the water in a medium pot. Bring to almost a boil, the water should be rippling. Remove the kombu. Add the bonito flakes**, return it to a high simmer for 5 minutes, then skim out the bonito. You have just made the simple dashi (broth) that is the base of miso soup. Add the cubed tofu and greens. Simmer 5 minutes. Stir in the dissolved miso and evenly distribute it. Cook for 1 minute. Remove from heat, allow to cool for one minute then serve.

Optional: garnish with green onions or garlic chives.

Yield: 4-6 servings

*Normally we use Shiromiso or “white” miso, but this time I used Akamiso or “red” miso. They taste slightly different from each other but both are commonly used to make miso soup.
**Optional, add a few dehydrated shiitake mushrooms at this point and remove them when you skim out the bonito then add them back in when you add the miso.

My thoughts:

Miso soup is so simple I almost hesitated to post the recipe. However, I have gotten a lot of requests for a recipe for miso soup so the last time we got sushi, I made some homemade miso soup and actually measured out my ingredients so I could share it with you. I don’t do anything too radical but I do like to make my own simple broth (AKA dashi, which is a great base for a lot of Japanese cooking) instead of using instant dashi powder and I am of the “don’t let it boil” school of miso soup-making. I find a high simmer (think ripples, not bubbles) yields the best flavor.

Like I said, miso soup is easy to make but it does require a few very specific ingredients. I have had no problem finding miso paste (which, incidentally, keeps for months in the refrigerator if tightly sealed), bonito flakes, kombu (a variety of kelp, you need it for making sushi rice , so it is worth keeping on hand and also has a long shelf life) at pretty much any Asian market (even Safeway sells most of it) but finding good quality wakame seaweed is sometimes an issue. I frequently just use some other kind of green: baby bok choy, kai choy, tat soi etc instead. I also like to heat up any leftovers for breakfast the next day. It isn’t quite as tasty as it is freshly made but not bad.


  1. Mmm, I love Miso soup.

  2. If the kombu is a type of seaweed or nori as it appears to be from the linked page, you don’t need that to make sushi rice. You would need it to make the rolls though.

  3. Alright, the times I’ve made sushi rice (trust me it’s a lot haha) all we’ve used is the rice, water, sugar, rice wine vinegar, citrus slices, and salt. I’d never heard of kombu before and the Amazon page doesn’t say too much about it.

  4. Fi,
    No, it isn’t the same type of seaweed as you use to make the rolls. It is much thicker, has a different flavor and is often using in the making of sushi rice (although some leave it out, I always use it and and most Japanese recipes seem to call for it) and it always present in dashi.

  5. Fi:

    Here is a link to the wikipage for kombu that might give you some more info.

  6. oh yum! i’ve never made miso soup at home, but i’m happy to have a tried and true recipe!

  7. My Japanese grandmother told me that the reason why she doesn’t let the soup boil is because the boiling water will kill all of the probiotics that live in the miso. Miso is like yogurt, and has all kinds of good bacteria living in it. Maybe that’s what makes it taste so good!

  8. I’ve only ever made instant miso soup at home… now I feel like a schlub!

  9. Oh, now you’ve got me craving Japanese! I love the slightly salty tinge of Miso soup.

    I like my miso with EXTRA seaweed. Also, I like to add a little brown rice when I serve it so it’s more filling

  11. Oh, I am so glad you posted the recipe, as my miso cookbook is packed away in storage while we renovate our home. I ate macrobiotic for 1 year ages ago. It is the best I ever felt and looked. Dined on miso soup every morning. Fabulous!

  12. Where would you kind kombu and bonito flakes at, say, HEB?

  13. Sarah, I would have no idea where you could find these products at the HEB. That is something you need to ask the employees of that store about.
