Story behind the soup
So, what inspired this soup? Honestly, it was pure curiosity.
For years, I’d heard about the wonders of dried shiitake mushrooms in traditional Chinese medicine and East Asia cooking. But only recently did I give them a real chance—and wow. They add a mushroom flavor and depth that turns a basic vegetable broth into something extraordinary.
There’s also a fun fact: umami is the "fifth taste" (after sweet, salty, sour, and bitter). The term itself was coined in Japan, thanks to research into kombu seaweed.
Fresh shiitake mushrooms are rich in umami flavors, which is why they’re a key player in Asian cuisine. So are ingredients like miso paste and sesame oil, which layer the soup with even more savory goodness.
Another standout is kabocha squash. Its deep orange color, sweet flavor, and meaty texture make it feel like a cross between sweet potato and pumpkin. If you haven’t tried it, you’re missing out.
Ingredients
Let’s talk about what you’ll need for this shiitake mushroom soup recipe.
These ingredients work together to create a delicious soup full of textures and umami flavors.
Dried shiitake mushrooms
These are the secret to your flavorful broth. In traditional Chinese medicine and East Asia, dried shiitake mushrooms are prized for their earthy richness and satisfying chew. Simmered with kombu, they create a deep, savory mushroom broth.
Kombu seaweed
Kombu is a dried seaweed that builds the base of your broth. It’s rich in glutamic acid, the compound behind umami flavors. Kombu transforms hot water into something nourishing and complex.
Fresh shiitake mushrooms
To go with the dried version, fresh mushrooms bring even more texture. These stay tender in soup and add woodsy depth.
Kabocha squash
This Japanese squash has a creamy texture and sweet flavor. Roasted with olive oil, fresh ginger, and a pinch of salt, it caramelizes beautifully and pairs well with bok choy and noodles.
Fresh ginger
Fresh ginger brings brightness and warmth. It mellows as it simmers and adds subtle heat to your flavorful broth.
Scallions / spring onion / green onions
Thinly sliced green onions (or spring onion) add color and zip. They’re sprinkled over the bowl at the end for extra crunch.
Red miso paste
Red miso paste is bold and fermented, perfect for this creamy mushroom soup. Stir it in at the end—off the heat—to preserve its flavor and nutrients.
Udon noodles
Thick, chewy udon noodles turn this into a satisfying noodle soup. They’re widely available and add body to the dish.
Mirin rice wine
This adds mild sweetness and balances the umami flavors. If you need a substitute, try rice vinegar with a little bit of sugar.
Baby bok choy
Bok choy adds crunch and freshness. It soaks up the broth while staying crisp.
Asian pear
Asian pear offers contrast—crisp, mild, and not too sweet. It holds its shape and adds dimension to your creamy mushroom soup.
Sesame oil
A drizzle of toasted sesame oil at the end ties everything together. It’s nutty, warm, and perfect with Asian cuisine.

Some items like dried shiitake mushrooms, kombu, and miso paste might not be in every grocery store.

Step-by-step instructions
1. Make the mushroom broth
Add kombu and dried shiitake mushrooms to hot water in a large soup pot. Simmer over medium heat for about an hour. Strain out the solids and save your flavorful broth.
2. Roast the squash
Preheat the oven to 375°F. Slice and prep your kabocha. Toss with olive oil, fresh ginger, and salt. Roast until golden.
3. Simmer the soup
Add minced ginger, fresh mushrooms, tamari or coconut aminos, and mirin to your broth. Simmer 10–15 minutes for deeper flavor.
4. Cook the noodles and veggies
Add udon noodles, bok choy, Asian pear, and green onions. Cook just until tender.
5. Finish with miso
Ladle out a bit of broth, mix in your miso paste, and return it to the pot (heat off). This keeps the miso fresh and flavorful.
6. Serve and garnish
Scoop everything into bowls. Add roasted squash, a swirl of sesame oil, and sliced spring onion or green onions for extra crunch.
Cooking Tips
- Use a paper towel to pat the squash dry for better caramelization.

- Simmer the mushroom broth gently for the best flavor.
Variations

- Use plant-based milk for creamier broth.
Storage
Store noodles and soup separately for best texture. Reheat over medium-high heat, adding hot water or broth if needed.

Shiitake Mushroom Miso Broth with Udon and Ginger Squash
Ingredients
- ½ ounce 15 grams kombu seaweed
- ½ ounce 15 grams dried shiitake mushrooms
- 6 cups water
- 1 ½ pound kabocha squash
- 1 tablespoon vegetable oil
- 3 tablespoons fresh ginger root, minced (portion 1 tablespoon, 2 tablespoons)
- 6 fresh shiitake mushrooms, sliced
- 3 tablespoons tamari
- 3 tablespoons mirin, Japanese cooking wine
- 8 ounces udon noodles
- 8 heads baby bok choy, sliced lengthwise
- half an Asian pear, sliced
- 4 scallions, sliced on the diagonal
- 3 tablespoons red miso
- sesame oil, for garnish
Instructions
- Make the stock. Bring water to a boil. Simmer kombu and dried shiitake mushrooms for about an hour. Strain out the vegetables and retain the stock.
- Meanwhile, prepare the squash. Preheat the oven to 375 degrees. Cut the kabocha in half. Use a large spoon to scoop out the seeds. Cut the skin off the squash using a large chef’s knife. Alternately, try using a peeler to remove the skin.
- Cut the squash into three-quarter inch thick slices. Toss the squash in a large bowl with the vegetable oil and 1 tablespoon of the ginger. Line up the squash on a baking tray lined with parchment. Bake for about 20 minutes until nicely browned, turning a few times to ensure even browning. Remove from the oven and set aside until needed.
- Simmer the broth for about 10–15 minutes with minced ginger, shiitake mushrooms, tamari, and mirin. Add udon noodles, baby bok choy, Asian pear, and scallions, and simmer for another 3–4 minutes.
- Remove about half a cup of broth from the stock and mix it with the red miso until it is a smooth paste. Turn the heat off the broth and stir in the miso.
To serve
- Serve in wide bowls and top with squash slices and a drizzle of sesame oil.
