What is Umami?
Miso is super healthy, but it’s also delicious because of it’s umami flavor. Umami is a term used to describe the fifth basic taste that is often referred to as savory or meaty. It adds depth and complexity to dishes, like in this miso soup. Umami-rich ingredients can enhance the flavors of other ingredients, creating a endless opportunities to create so many delicious dishes.
This taste is associated with foods that are rich in glutamate, an amino acid that naturally occurs in many foods. The discovery of umami is attributed to a Japanese chemist, Kikunae Ikeda, who identified the unique taste in dashi, a Japanese broth made from kombu seaweed and bonito flakes.
Consuming umami-rich foods can increase feelings of satiety, as well as enhance the absorption of certain nutrients.

What’s the History Behind Miso Soup?
Miso soup is a traditional Japanese dish that has been enjoyed for centuries. It is a simple yet flavorful soup made from a combination of miso paste, dashi stock, and various ingredients such as tofu, seaweed, and scallions. This delicious soup makes a great side or main dish, depending on what’s added to it.

The Components of a Vegan Miso Soup
The vegan dashi: Dashi is a stock made with kombu, which is dried kelp. This ingredient will infuse and create a deep and complex umami flavor.
You can prepare vegan dashi by placing a piece of kombu (which can be found in any Asian market) in cold water to steep overnight or simmer the kombu for about 20 minutes before serving. To release more of the flavor, cut slits on the sides before steeping it.

Miso: Miso is produced by fermenting soybeans with salt and a fungus called Aspergillus oryzae. During this fermentation process, the microorganisms break down the carbohydrates, proteins, and fats present in the soybeans into simpler compounds. During this time, the production of amino acids, vitamins, and minerals are created.
The fermentation process increases the availability of these amino acids, making them easier for the body to absorb and utilize. Additionally, miso contains antioxidants, a high content of probiotics, and is an excellent source of protein. It also contains calcium, iron, magnesium, and potassium, making it highly nutritious.
Miso tip! To retain the nutrients in miso or in any dish using miso, always add it at the very end of prep once it’s removed from the heat and never allow it to boil. This will degrade all of the nutritional benefits.
I absolutely love South River Miso brand, but can’t find it in the South Bay, so Miso Master has become my go-to brand here.
Dried shiitakes: This is going to add more umami and a deep earthy flavor to the dashi. Since the shitakes are dried, they are going to release an intense, concentrated flavor.
Optional Ingredients to Add to the Miso Soup
Mushrooms: If you love mushrooms, add any kind you like, and experiment with trying new ones. Some good choices are meaty maitakes, enoki, king oyster, oyster and shiitakes.
Noodles: Add ramen noodles, udon noodles or maifun noodles.
Vegetables: Use what you’ve got and what you like! I’ve used carrots and scallions here, but kale, cabbage, snap peas, or bamboo shoots would also be great additions.
This easy vegan miso soup can be served for a savory breakfast, lunch, light dinner or side.

Vegan Miso Soup
- Total Time: 30 minutes
- Yield: 2 servings
- Diet: Vegan
Description
This vegan miso soup is the kind of simple, cozy bowl that just feels good to make. A quick kombu-and-shiitake steep builds a surprisingly deep broth, and whisking in the miso at the end keeps everything warm and bright. Add tofu, scallions, or mushrooms and it turns into the easiest comfort meal.
Ingredients
For the vegan dashi
- 1 piece kombu (about 3X3 inches)
- 4–5 cups filtered water
- 4 dried shiitake caps
To finish the soup
- 1 tablespoon miso paste per cup of dashi (any kind you like)
- 1 teaspoon soy sauce
- 1 teaspoon toasted sesame oil
Optional add-ins
- wakame (a small pinch, as it rehydrates quickly)
- soft or firm tofu cubes
- mushrooms, any kind you like (shiitake, enoki, oyster)
- scallions, sliced
- spinach
Instructions
Prep the kombu
- Gently wipe the kombu with a damp cloth to clean it—do not rinse.
- Cut a few slits along the edges to help release more flavor.
Make the dashi
Hot Dashi (Option 1)
- Add 5 cups filtered water, kombu, and dried shiitakes to a medium saucepan.
- Bring to a gentle simmer over medium heat (do not boil). Steep for about 20 minutes.
- Skim off any froth that rises to the surface.
- Remove the kombu and shiitakes. (Slice the shiitakes and add to the soup later if you’d like.)
Cold Dashi (Option 2)
- Add 4 cups filtered water, kombu, and dried shiitakes to a container.
- Cover and refrigerate for 12 hours.
- Remove the kombu and shiitakes before using.
- Warm the cold dashi gently on the stovetop.
Instant Dashi (Option 3)
- Dissolve vegan dashi powder into hot water according to package instructions.
Add the miso and flavorings
- Remove the dashi from the heat and whisk in the miso, soy sauce, and toasted sesame oil.
Finish the Soup
- Ladle the vegan miso soup into bowls.
- Add a small pinch of wakame.
- Top off with any add-ins you like: such as tofu, mushrooms, scallions, and greens.
Notes
- Don’t boil the miso: Add it off the heat to keep the flavor bright and to protect its beneficial enzymes.
- Adjust the miso to taste: Start with 1 tablespoon per cup of dashi and add more if you want a stronger, saltier miso flavor.
- Store the broth separately: The kombu–shiitake dashi keeps for 3–4 days in the fridge. Reheat gently, then whisk in fresh miso before serving.
- Add wakame to each bowl: Wakame keeps hydrating as it sits, so add a small pinch per serving rather than to the whole pot.
- Use the rehydrated shiitakes: Slice the softened mushrooms and add them to the soup, or store them for 3–4 days for stir-fries or stock.
- Swap in vegan dashi powder: If you’re short on time, dashi powder makes a clean, savory broth in seconds.

Nice recipe, and good tip on not letting the miso paste get too hot. Thanks!
