15 Minute Miso with Buckwheat Noodles and Sweet Potatoes

Sweet White Miso


When life gives you miso, you make soup. Not the classic simple version, something a little bit more complex, but worth while. For me lunch is better if there's soup involved, so whenever I eat out, I get super excited to see what's the soup of the day, especially if they serve it in sensible portions. Miso however usually stays the same, unless you give it a little twist at home. It's simple, really.

What Makes a Good Miso Soup?

To begin with, you need to have certain ingredients in your pantry, which you can later also use in different meals, so don't be afraid of buying a bigger pack of miso paste or buckwheat noodles. You can use miso paste for salad dressings, soups, tofu for stews or even vegan desserts. Buckwheat noodles can be stir fried or eaten cold in a salad.

Basic miso ingredients:

  • miso paste - fermented soy bean paste (I use sweet white miso for it's subtle flavour and that's what's normally used)
  • silken tofu (the soft kind)
  • seaweed, e.g. "wakame"
  • scallions (spring onions)
  • water

You can then add any extra ingredients if you wish, like I added GF buckwheat soba for a more filling version which is also gluten free. I also pan fried some thinly sliced sweet potatoes and a bit of carrot then finished off with black sesame seeds. Because I LOVE pretty.


Try specialised gourmet shops, asian supermarkets or simply a bigger supermarket. I usually get mine (in Lithuania) from "Assorti" Ogmios Miestas specialty food store.
