A warm broth with miso paste, tofu, egg, and spring onion — a light Japanese soup low in calories and carbohydrates that works beautifully as a first course.
Miso soup is a cornerstone of the Japanese table: a warm broth brought to life with fermented soybean paste and tofu.
Very light and low in calories yet rich in plant-based protein, it is served as the start of a meal or alongside rice.
Heat the water with the broth and dashi powder until warm but not vigorously boiling. Add the sea vegetables if using, and let them rehydrate. Dashi provides the characteristic depth of umami flavour.
Ladle a little hot broth into a small bowl and dissolve the miso paste in it until smooth, then return it to the pot. Dissolving it separately prevents clumping in the soup.
Gently add the silken tofu cubes so they do not break apart, and let them warm through. Tofu boosts the plant-based protein content.
Pour the beaten egg in slowly while stirring gently, so it forms delicate ribbons in the broth. Gentle stirring creates those beautiful egg threads.
Remove the pot from the heat before boiling so the miso retains its flavour. Garnish the soup with spring onion and serve hot. A light, soothing Japanese soup.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.
* Percent Daily Values are based on a 2,000-calorie diet per FDA food-label reference values — your daily needs may be higher or lower. Values are derived from the recipe's ingredients via the USDA database.
The most common problems when preparing Japanese Miso Soup, and how to fix them:
Too little oil or a cold pan. Heat the pan and add enough oil before the ingredients, and do not crowd the pan.
Heat too low or cooked too long. Stir over high heat for a short time to keep the vegetables crisp and bright.
Not enough salt or seasoning. Season generously and taste, then add a fresh herb or a squeeze of lemon to lift all the flavours.
Three days in an airtight container after cooling. Reheat thoroughly before serving.
One to two months in individual portions. Thaw in the refrigerator before reheating.
Prep and chop the ingredients in advance and refrigerate; assembly and cooking takes only minutes at serving time.
Over low heat with a splash of water, or in a moderate oven until hot. Do not leave cooked food out of the refrigerator for more than two hours [2].

Do not boil the miso or it will lose its flavour and beneficial bacteria. Dissolve it separately to prevent clumping. Miso is high in sodium so use it in moderation, and tofu adds plant protein with very few calories.
