Before you cook
Background Recipe story & origin
Miso soup (味噌汁, misoshiru) is fundamental to Japanese cuisine, served at virtually every meal including breakfast. The soup consists of dashi stock with dissolved miso paste and various additions. Miso, a fermented soybean paste, has been made in Japan for over 1,300 years. Different regions favor different miso types: white (shiro) miso is sweet and mild, common in Kyoto; red (aka) miso is salty and robust, popular in central Japan. The soup shows Japanese culinary philosophy: simple ingredients, pure flavors, proper technique. The critical rule is never boiling miso, which destroys both flavor and the beneficial probiotics from fermentation.
Before you start Equipment you'll need
- pot — Provides gentle heat for making soup with proper temperature control and even cooking
- fine mesh strainer — Provides smooth dissolution of miso paste without lumps for silky soup texture
Safety Safety & allergen notes
- Never boil miso; it kills beneficial bacteria and turns bitter.
- Add miso off heat or at bare simmer.

-
Use proper dashi.
Dashi provides the umami foundation; water makes flat soup

Make the soup
Bring dashi to a simmer in a pot. Add tofu and wakame, simmer gently 2 minutes. Remove from heat. Place miso in a fine mesh strainer, lower into pot, and whisk to dissolve miso into soup (or dissolve miso in a small amount of hot dashi first, then add to pot). Do not boil after adding miso.

Bowl and serve
Ladle into bowls, distributing tofu and wakame evenly. Top with sliced scallions. Serve immediately.
