1 tablespoon grated ginger
4 cups vegetable broth
1/4 cup white miso paste, or more to taste
To finish
Drizzle of toasted sesame oil

Heat oil in heavy large saucepan over medium heat. Add carrots, onion and garlic sauté until onion is translucent, about 10 minutes. Add broth and ginger. Cover and simmer until carrots are tender when pierced, stirring occasionally, about 30 minutes.
