01 - Heat olive oil in a large pot over medium heat. Add the diced onions and cook for 3 to 4 minutes until they become translucent and softened.
02 - Add the minced garlic and grated ginger to the pot. Sauté for about 1 minute until fragrant, stirring frequently to prevent burning.
03 - Stir in the sliced carrots and cook for an additional 2 minutes, allowing them to lightly soften and absorb the aromatic flavors.
04 - Pour in the vegetable broth and bring the mixture to a boil. Once boiling, reduce the heat to low and simmer for 18 to 20 minutes until the carrots are fork-tender.
05 - Remove the pot from heat. Using an immersion blender, puree the soup directly in the pot until completely smooth. Alternatively, transfer in batches to a standard blender and blend until silky.
06 - In a small bowl, dissolve the white miso paste by whisking it with a ladleful of hot soup. Pour the dissolved miso mixture back into the pot and stir in the soy sauce. Season with salt and pepper to taste.
07 - Warm the soup gently over low heat if needed, but do not bring to a boil after adding the miso, as high heat diminishes its probiotic benefits and flavor.
08 - Ladle the soup into serving bowls. Top with thinly sliced scallions and a sprinkle of toasted sesame seeds for a beautiful finishing touch.
