Ok, so today I was craving some miso soup and I wanted to add some noodles to it to make it more of a full lunch for today.

I also decided to look at some vegan options for you vegans out there because normally there’s dashi in miso soup and I found a way to create some vegan dashi to add to the miso soup.

  • Mason jar or another container for the dashi


Vegan dashi

  • 4 dried shiitake mushrooms
  • 1 sheet kombu
  • 2 cups water

Miso soup

  • 1 bundle ramen noodles
  • 2 tbsp miso paste
  • 1 stalk green onions
  • 1 hand dried wakame


Vegan dashi cold brew

  • Let’s first make the vegan dashi: you’ll need two cups of water, four dried shiitake mushrooms, and one long piece of kombu seaweed.
    This is enough for around four people, four servings of soup but making less than this will be hard to soak the kombu in.

  • Now soak the mushrooms and seaweed in water for 30 minutes in a jar or a bowl. I use a mason jar for this.
    You can soak them for 12 hours in the fridge for more flavorful results. I definitely recommend doing that.
  • After the dashi has had time to soak, open the jar and pinch the mushrooms to get all of their flavors out then remove the mushrooms and the seaweed from the water and throw them away or use them in another recipe or in this case in this miso soup.
    Pinch the shiitake mushrooms to release flavors
  • Now strain your stock by pouring the liquid through a fine strainer and remove any pieces of debris you see floating in it with a spoon now keep this stock in the fridge for no more than three days.

Miso soup

  • Ok, now in the meantime let’s cook some water and then boil our ramen noodles in it. Just follow the package. It’s usually around eight minutes or so, and while that’s boiling we can also start making our miso soup base.
    Just put the dashi broth on in a small pan and then add the shiitake mushrooms to it.
  • You want to boil them for a few minutes then, when it’s boiling, you can also add your miso paste to it.
    So now you have a nice miso dashi base broth. Just stir it a little so all the miso gets absorbed in the water then just let it stand for a few minutes.
    Give it some time to boil for a few minutes then scoop out the shiitake mushrooms, they’re done and you can cut them later.
    Add miso to the broth
  • Now let’s cut the green onion into small pieces. You can add those to the bowl, then add in your dried wakame seaweed, some noodles (they can be cold), and then you just pour over your hot miso soup.
    Then cut your mushrooms and add one or two to your bowl and give it a little stir, and there’s your soup!

Ok, so that’s it. I hope that you’ll enjoy it as much as I did making it and of course, eating it for my lunch.

I also have another recipe for you. It’s even easier to make miso soup with a pre-packaged miso base and pre-packaged miso ingredients and all of the dried ingredients that you’ll need.
