In a large pot, on medium/low heat, add the olive oil, onions, garlic, carrots, sweet potato, salt and pepper. Saute for about 7-8 minutes.
Then add in the ginger, turmeric, white miso, 3 cups of broth (start with 3 cups and add more later if you want a thinner consistency), coconut milk, and a little more salt and pepper. Cover and cook on medium heat for about 20 minutes or until the veggies are soft.
Transfer everything into a blender (you may have to do it in batches) and blend until smooth. If it's too thick, you can add more coconut milk or broth if needed. Adjust seasoning as needed and enjoy.
