Miso soup is a savory, cloudy Japanese broth made from fermented soybean paste (miso) dissolved in dashi stock, often containing small cubes of silken tofu and seaweed. It has a deeply umami, salty, and slightly sweet flavor with a light, watery texture punctuated by soft tofu. Nutritionally, it's a low-calorie, plant-based source of protein and probiotics from fermentation.

↓ Full nutritionPeople love it for its comforting, umami-rich warmth that serves as a perfect starter or light meal, and its deep roots in Japanese cuisine and culture, symbolizing simplicity and nourishment.
It can be high in sodium, which may be a concern for those with high blood pressure, and miso contains soy, a common allergen. To counteract, use low-sodium miso, add extra water to dilute, and pair it with unsalted sides like plain rice or steamed vegetables.
Traditional miso soup is never boiled after adding the miso paste, as high heat kills the beneficial probiotics and alters the delicate flavor.

Is miso soup vegan?
It can be, but traditional dashi stock often contains bonito (fish flakes). For a vegan version, use kombu (kelp) and shiitake mushroom dashi.
Can I reheat miso soup?
Yes, but gently. Avoid boiling it, especially after adding fresh miso paste, to preserve its probiotic benefits and nuanced flavor.
What is the white stuff in miso soup?
The cloudy white substance is the miso paste itself, which is a fermented mixture of soybeans, salt, and a koji culture (usually from rice or barley).
