3 tablespoons olive oil
1 large onion, chopped
2 cloves garlic, minced
1 tablespoon tomato paste
1 teaspoon ground cumin
1/4 teaspoon kosher salt, or to taste
1/4 teaspoon freshly ground black pepper
1/8 teaspoon chili powder, or to taste
1 (32 ounce) carton chicken broth
1 cup red lentils
1 large carrot, diced
2 tablespoons lemon juice, or to taste
3 tablespoons chopped fresh cilantro
4 teaspoons extra-virgin olive oil for drizzling
1 pinch chili powder
Heat 3 tablespoons of olive oil in a large pot over medium-high heat. Stir in the onion and garlic, and cook until the onion has turned golden brown, about 5 minutes. Stir in the tomato paste, cumin, kosher salt, black pepper, and 1/8 teaspoon of chili powder. Cook and stir 2 minutes more until the spices are fragrant.
Stir in the chicken broth, lentils, and carrot. Bring to a boil over high heat, then reduce the heat to medium-low, cover, and simmer until the lentils are soft, about 30 minutes.
Using an immersion blender, puree the soup in the cooking pot. If desired, you can just puree it for a minute or so, leaving it a little chunky.
Stir in the lemon juice and cilantro, then season to taste with salt. Drizzle with olive oil and a sprinkle of chili powder to serve.
