Eating miso soup is more than just a meal. It’s a cozy sensory experience that should feel comforting and like coming home. This version of miso soup is simple and can be kept that way, or built up with noodles, mushrooms and vegetables. It’s packed with umami, making it deeply flavorful and complex.

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.
