Carrot and Turmeric Soup with Za'atar Yogurt

Roasting carrots caramelizes their natural sugars and intensifies their flavor, resulting in a soup that’s rich and creamy, even though it doesn’t contain any dairy except for the yogurt in the garnish. For a vegan variation, after making the soup using vegetable broth, omit the yogurt mixture and simply garnish the soup with a bit of za’atar and cilantro.
