Miso soup, or misoshiru, is one of the most essential dishes in Japanese cuisine.
Served with almost every meal, it is simple, healthy, and endlessly versatile.
Made with a savory dashi broth and miso paste, miso soup is more than food—it is part of Japan’s daily rhythm of life.
Dashi: The Flavor Base of Miso Soup
Miso soup always begins with dashi, the broth that defines Japanese cuisine.
Dashi is simple to make, yet it carries a unique taste called umami—the “fifth flavor” beyond sweet, salty, sour, and bitter.
Here are the main types:
Kombu Dashi (Kelp Broth)
-
Made by soaking or gently heating dried kelp (kombu).
-
Delivers a clean, subtle umami with a hint of ocean aroma.
-
Used in Buddhist vegetarian cooking (shojin ryori).
Katsuobushi Dashi (Bonito Flake Broth)
-
Made from dried, smoked bonito shavings.
-
Strong savory taste with a rich aroma.
-
Most common base for everyday miso soup.
Awase Dashi (Mixed Broth)
-
Combination of kombu and katsuobushi.
-
Balances the clean depth of kelp with the bold flavor of fish.
-
Considered the “standard” dashi in many households.
Niboshi Dashi (Dried Sardine Broth)
-
Made by simmering dried baby sardines.
-
Rich umami with a slightly bitter edge.
-
Popular in some regional soups, especially hearty countryside versions.
Shiitake Dashi
-
Made from dried shiitake mushrooms.
-
Earthy and mellow, adds depth without fish.
-
Often paired with kombu for a vegetarian-friendly option.
👉 This flexibility is why dashi is the backbone not only of miso soup, but of much of Japanese cuisine.
