Select the substitute based on your dish and desired texture or flavor profile.
Prep the mushrooms as needed: slice shiitake stems thin, soak dried shiitake, or add oyster mushrooms near the end of cooking.
Use the substitute in a 1:1 volume ratio to maitake mushrooms, or equal parts for mixed blends.
Adjust cooking time: shiitake and portobello need longer cooking, oyster mushrooms should be added last to maintain texture.
Taste and check texture to ensure the substitute complements your recipe as desired.
