Heat the oil in a large pot over medium-high heat. Add the onions, carrots, thyme, 1 teaspoon salt, and ½ teaspoon pepper. Cook, stirring often, until the onions are tender, 10 to 12 minutes. Add the water and bring to a boil. Reduce heat and simmer, stirring occasionally, until the carrots are completely soft, 12 to 15 minutes.
Puree in a blender, in batches, until smooth. Stir in the carrot juice and vinegar. Store in an airtight container for up to 1 week. Reheat over a low flame.
Serve the soup warm, topped with herb yogurt or sour cream.
Tip: Not a carrot fan? Try the recipe with 4 pounds of peeled squash, cooked with 8 cups of chicken broth instead.
