Step 1

Toast cumin seeds in a large pot over medium-high, stirring often, until fragrant, about 1 minute. Remove from pot. Heat oil in pot. Add carrots and shallots; cook, stirring often, until shallots are very tender, about 6 minutes. Stir in ginger, turmeric, and toasted cumin. Cook, stirring constantly, until fragrant, about 30 seconds. Stir in broth and lentils; bring to a boil. Reduce heat to medium-low and simmer until carrots and lentils are tender, about 20 minutes.

Step 2

Blend carrot mixture in a blender, in batches if necessary, taking care when blending hot liquids. (Or use an immersion blender directly in pot.) Return pureed soup to pot. Stir in coconut milk, 1 cup water, salt, and pepper. Top with cilantro.
