Spicy Summer Miso Soup

A show-stopper miso soup made with a spicy broth punched up with garlic, ginger and chile paste. To that you add cubed potatoes, chopped cabbage and summer produce like cherry tomatoes, basil, and corn.

Spicy Summer Miso Soup

I was paging through my notebook the other day, and stopped on a show-stopper miso soup I love. It's something I cook a few times every year. Frankly, I'm surprised it has taken this long to share the recipe, but here we are! The foundation of this soup is the broth. It is a *punch* of flavor built on garlic, ginger, scallions, toasted sesame oil, miso and fermented chile paste. The broth is made creamy with a finishing dollop of good tahini. Building the soup from there, I always add cubes of waxy potatoes and lots of chopped green cabbage. It's all finished off with cubes of tofu and a blitz of anything summery. Cherry tomatoes are cut into crescents, young yellow beans, sweet fresh corn, and slivered basil are all fair game. Those of you with gardens - raid them.

More About the Broth

The broth here is a riff on the Hot Sesame Miso Broth in Naoko Takei Moore and Kyle Connaughton's Donabe book. This broth was "inspired by the Japenese ramen dish tan tan men, which is derived from the Chinese dan dan mein, or dan dan noodles." You see it in the book served hot pot style with chicken meatballs. I jumped off the broth as a starting point and took the whole situation in a veg. direction, introducing the potatoes and cabbage and finishing with all things summery seasonal from there.

Let's talk Spicy - What is Tobanjan?

Tobanjan is the spicy component here. It's a feisty, salty, fermented bean paste that has become indispensable in my kitchen for its nuanced, layered heat - the love here is deep. I buy 3-4 little jars (above) at a time when I visit Tokyo Central in Orange County, Ca. You can also find it online - this is the brand Naoko stocks at her shop, Toiro Kitchen. Where I spend all my money on donabe - laugh/cry. Swap in another spicy paste or sauce if you don't want to go down the tobanjan rabbit hole - the soup will be different, but still delicious.

As the seasons progress you can, of course, adapt with other ingredients. That's the great thing here, a mushroom version is great later in the year. You can add some winter squash in with the potatoes, radicchio, etc. And in spring asparagus, fava beans, spring onions, and spring peas make an entirely different version. Have fun with it.

Spicy Summer Miso Soup

4.82 from 11 votes

I'm pretty casual with the finishing touches here. Use a good drizzle of whatever favorite olive oil you have and chop up any chives or scallions. Basically, what I'm saying is that once you have the broth made and the potatoes and cabbage in the pot, play around with whatever seasonal ingredients you have on hand to add.

  • 1 tablespoon toasted sesame oil
  • 1 tablespoon minced ginger
  • 2 tablespoons minced garlic
  • 8 scallions or ½ an onion, finely chopped
  • 1 tablespoon tobanjan (or other spicy paste – curry, etc.)
  • 5 cups water
  • 1 tablespoon miso (preferably red)
  • 1 tablespoon soy sauce
  • ---------
  • 2 cups waxy potatoes, cut into 1/2 – inch cubes
  • 2 cups chopped green cabbage
  • 1/4 cup good-quality tahini
  • add-ins: tiny tofu cubes, quartered cherry tomatoes, bite-sized segments of yellow beans, corn
  • topping ideas: lemon olive oil, slivered basil, more scallions, chives
  1. While the sesame oil is heating in a large pot, chop and smash the ginger and garlic into a paste. Sauté the paste along with the scallions (or onion) for a few minutes, until aromatic. Add the tobanjan and stir well for 30 seconds. Add a splash of the water along with the miso and soy sauce. Add the rest of the water and bring to a simmer. Taste and adjust with more soy sauce or more tobanjan if needed.

  2. Add the potatoes and simmer until just soft. Stir in the cabbage and any tofu, tomatoes, and other summer produce you're using. Allow to cook for a few minutes, and then stir in the tahini. Serve the soup topped with a drizzle of lemon oil, slivered basil, scallions and/or chopped chives.


Serves 4.

Hi Heidi: I made this last week- it was wonderful! I used shallots instead of the onion, white
miso and spicy red curry paste as I didn’t have tobanjan (and of course, now I know what it is!) This will be a year round soup for us. It’s a great base to pile on seasonal vegetables. Thanks!5 stars


    Thanks Chapulis – so happy you enjoyed it!

    Heidi Swanson

    Thanks Joyce!!
