Is Miso Soup Vegan: 5 Benefits, Ingredients and More

Is Miso Soup Vegan?

Miso soup is a very popular traditional Japanese soup that is made of a base stock, miso paste, and various other ingredients that vary depending on the recipe. Miso soup has become more popular in Western countries too, although many people have adopted a plant-based or vegan diet. As such, you may wonder whether miso soup suits a diet that excludes animal foods.


The name miso soup originated from the name of its primary ingredient called miso paste. Miso paste is a salty and flavorful Japanese condiment that is derived from fermented soybeans. To make the miso paste, soybeans are properly mixed with salt and a mold called koji. It may also include barley, rye, rice, and other grains.

The base or primary ingredient in miso soup is dashi, which is one of the important families of Japanese stocks. Some miso soups are made with katsuobushi dashi, which is a stock containing katsuobushi, or bonito flakes. These non-vegan flakes are made of smoked skipjack tuna.

Niboshi dashi is another popular type of miso soup that uses dried Japanese anchovies instead of tuna in its stock. As such, it’s likewise not vegan. Some Americans and Europeans make their own versions of miso soup by dissolving miso in chicken or fish stock, neither of which are vegan.

Note: Following a pescatarian diet, some types of miso soup do not potentially fit into the diet. But if the miso soup is prepared without using chicken stock or contains fish-derived ingredients, then it is a vegan diet.

Another type of miso soup is called Kombu, which is made with kombu dashi, a stock derived from kelp, a type of seaweed. Other types of miso soup may also contain other animal-derived ingredients. For example, some versions may include shrimp, clams, or pork (called tonjiru, which means pork soup in Japanese).

Note: Miso paste is generally considered vegan. However, the same may not hold true for miso soup.


Miso soup is incredibly nutritious and it’s linked to a variety of health benefits, which includes:

1. Miso soup helps with better digestion and a stronger immune system because the traditional Japanese condiment used in making it consists of a thick paste made from soybeans that have been fermented with salt and a koji starter. The starter usually contains the Aspergillus oryzae fungus.

2. The popular Japanese miso paste can be used to make sauces, spreads, and soup stocks, or to pickle vegetables and meat.

3. The varieties made from soybeans are considered to be sources of complete protein because they contain all the essential amino acids needed for human health.

4. The fermentation process used to produce miso makes it easier for the body to absorb the nutrients it contains.

5. The fermentation process in miso soup also promotes the growth of probiotics, beneficial bacteria that provide a wide array of health benefits. A. oryzae is the main probiotic strain found in miso. 

The food’s flavor is generally described as a combination of salty and umami (savory), and its color can vary between white, yellow, red, or brown, depending on variety.
