Miso Soup with Onion and Potato

You may think that you must have tofu and/or wakame seaweed to make miso soup, but you can make it with just about anything you have at home.  If you have made miso soup before, the chances are that you still have plenty of dried bonito flakes to make dashi broth and some miso paste left in the fridge.  All you need is some onion and potato to make another authentic Japanese dish!

Onion and potato are pretty common ingredients for everyday miso soup in Japan, simply because everyone has them at home and it’s quite tasty.  You don’t need to make a trip to the Japanese market this time!

If you have never made miso soup before, please watch our video first.  For quick recap of making simple and delicious dashi broth, watch this video.

    This soup is absolutely fantastic. I made the dashi using guides from this site and another, sort of mixing the two methods together. Then I just followed this to the letter and it turned out so awesome. While the potato and onion was cooking I steamed broccoli over it since I just bought a 12 quart steamer pot. It worked wonderfully. I also had shrimp which had been steamed with Budweiser Black Crown beer. The soup though was really the highlight of the meal though.

    Thank you for posting all this and I can’t wait to get to the rest of the stuff on this site (waiting for the sake and hon-mirin to come UPS).

        It really is very handy and adds such wonderful types of flavor. I made a second batch of the soup, but this time I added celery and garlic clove finely diced since I had both on hand and wanted to use it up. I honestly think it came out even better than anticipated. It was more or less an experiment. I use my gut to decide how much of each to put in and I must have been on point because it was wonderful.

        I think I enjoy it more than my New England Clam Chowder and this is so much simpler to make.

    Hello I love your website! I was wondering if dashi amd hon dashi were the same thing? Can hon dashi be used for miso soup?

      Hondashi is instant powder dashi you can dissolve in hot water. Yes, you can use that for your miso soup, but it is easy to make real Dashi. We have Dashi and Ichiban Dashi recipes!

    Helo Yuko,

    I thought the “content” of Miso Soup are only tofu and wakame.
    NOW I know they are another stuff I can put on that Soup.
    TQ for sharing your detail and easy recipe.
