Ingredients
  

  • 3 tablespoons olive oil plus more for drizzling
  • 1 large onion, chopped
  • 2 garlic cloves, minced
  • 1 tablespoon tomato paste
  • 1 teaspoon ground cumin
  • Salt and black pepper to taste
  • pinch chili powder or ground cayenne plus more to taste
  • 1 quart chicken or vegetable broth
  • 1 cup red lentils
  • 1 large carrot peeled and diced
  • 1/2 lemon juice more to taste
  • 3 tablespoons chopped fresh cilantro

Method
 

  1. Heat three tablespoons of oil in a large pot over high heat until shimmering. Add the onion and garlic and sauté for about four minutes, until golden.
  2. Add tomato paste, cumin, 1/4 teaspoon each of salt and black pepper, and the chili powder. Sauté for an additional 2 minutes.
  3. Add two cups of water, broth, lentils, and carrot to the pot. Bring the mixture to a simmer. Partially cover the pot, reduce the heat to medium-low, and simmer until the lentils are tender, approximately 30 minutes. Taste and season with salt as needed.
  4. Purée half the soup with an immersion blender, regular blender, or food processor. Return it to the pot, leaving the soup somewhat chunky.
  5. Reheat the soup if needed. Stir in lemon juice and cilantro. Serve drizzled with quality olive oil and lightly dusted with chili powder, if desired.

Notes

Ingredient Swap: I love using sweet potato instead of carrot sometimes for a slightly sweeter, heartier soup, and it cooks in the same amount of time.
Storage Secret: This soup thickens beautifully overnight in the fridge.
I always thin it with a splash of broth or water when reheating for the perfect consistency.
Make-
Ahead Tip: You can cook the soup completely, let it cool, and store it for up to 3 days before adding the final lemon juice and cilantro.
Stir those in just before serving to keep their flavors bright.
Common Mistake: Don't skip sautéing the tomato paste and spices with the onions.
I learned this builds a much deeper, richer flavor base that makes the whole soup sing.
Serving Suggestion: A drizzle of good olive oil and a sprinkle of chili powder on top isn't just for looks.
It adds a wonderful layer of fragrance and a little heat that I think really finishes the bowl.
Equipment Note: If you don't have an immersion blender, carefully blend a portion in a regular blender.
I always remove the center lid cap and cover the hole with a folded kitchen towel to let steam escape safely and avoid a soup explosion.
Personal Touch: I sometimes stir in a big handful of fresh spinach right at the end, just until wilted.
It adds a lovely color and makes it feel even more nourishing.
