This easy mushroom miso soup is a simple and comforting bowl of goodness that's easy to make. Bursting with umami flavors and rich in nutrients, this recipe is perfect for a quick and satisfying meal.
Rinse the dried shiitake mushrooms, then put them in a small bowl with a cup of hot water. Allow them to soak for 20 minutes.
In a large pot, combine the re-hydrated mushrooms along with their soaking liquid, sliced portobello mushrooms, soy sauce, ginger, and sesame oil. Bring to a boil over medium heat. Reduce heat to medium low and simmer 15-20 minutes, or until mushrooms are tender.
In a small bowl, combine the miso paste with a scoop of the soup broth and mix until smooth.
Stir the miso paste into the soup. Allow the soup to come to a simmer, but don't boil.
Remove from heat and stir in the spinach.
Ladel into bowls and garnish with sesame seeds and shriracha, or sliced green onions.
Notes
Mushroom Stems: Shiitake stems are tough and woody, and should be removed before using them. However, most dried shiitake mushrooms have the stems already removed.
Rinse: Dried mushrooms should be thoroughly rinsed before soaking, to remove any debris. I use a colander.
Soak: Don't skip the rehydrating step. This mushroom miso soup comes together very quickly, but you do need plan for soaking the dried mushrooms for 15 minutes. And the soaking liquid adds a delicious extra layer of umami flavor to the soup.
Miso paste: It's important to stir in the miso paste at the end of cooking time. Never boil miso, because boiling will damage the aromatic notes and kill the probiotic properties.
Storage: Mushroom miso soup will keep, stored in an airtight container in the fridge, for up to three days. Reheat in the microwave or on the stovetop over low heat.
To Freeze: You can freeze this miso soup in a freezer safe container for up to two months. Defrost over night in the fridge.
