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
  • ¼ teaspoon salt, plus more to taste
  • ¼ teaspoon black pepper, plus more to taste
  • Pinch of chili powder or ground cayenne, plus more to taste
  • 1 quart chicken or vegetable broth
  • 2 cups water
  • 1 cup red lentils, rinsed and drained
  • 1 large carrot, peeled and diced
  • Juice of ½ lemon, plus more to taste
  • 3 tablespoons chopped fresh cilantro

Instructions

  1. Heat 3 tablespoons of olive oil in a large pot over high heat until hot and shimmering. Add the chopped onion and minced garlic. Sauté for approximately 4 minutes, stirring frequently, until the onion softens and turns golden.
  2. Stir in the tomato paste, ground cumin, ¼ teaspoon salt, ¼ teaspoon black pepper, and a pinch of chili powder or cayenne. Cook for another 2 minutes, stirring regularly to release the flavors of the spices.
  3. Pour in the chicken or vegetable broth and 2 cups of water. Add the rinsed red lentils and diced carrot. Stir well and bring the mixture to a gentle simmer.
  4. Partially cover the pot and reduce the heat to medium-low. Simmer for approximately 30 minutes, stirring occasionally, until the lentils and carrots are tender. Taste and adjust the salt if necessary.
  5. Using an immersion blender, carefully purée approximately half of the soup directly in the pot. Alternatively, transfer half of the soup to a regular blender, blend until smooth, and return it to the pot. The finished soup should be creamy but still slightly chunky.
  6. Reheat the soup over low heat if necessary. Stir in the fresh lemon juice and chopped cilantro. Taste and adjust the seasoning, adding more lemon juice, salt, or chili powder if desired.
  7. Ladle the warm soup into serving bowls. Finish with a drizzle of good-quality olive oil and a light sprinkle of chili powder, if desired. Serve immediately with crusty bread or warm pita.

Notes

  • Vegetarian and vegan option: Use vegetable broth instead of chicken broth to make the soup completely plant-based.
  • No soaking required: Red lentils cook quickly and do not need soaking. Rinse them thoroughly before cooking.
  • Adjust the consistency: If the soup becomes too thick, add a little warm water or broth until it reaches your preferred consistency.
  • Extra creamy texture: Blend the entire soup instead of just half for a completely smooth and velvety finish.
  • Spicy variation: Add extra cayenne pepper, crushed red pepper flakes, or a small spoonful of harissa paste for additional heat.
  • Coconut variation: Replace some of the broth with coconut milk for a richer, creamier soup.
  • Additional vegetables: Add celery, zucchini, spinach, or diced tomatoes for extra flavor and nutrition.
  • Serving suggestions: Serve with warm pita bread, crusty bread, a fresh green salad, or roasted vegetables.
  • Refrigeration: Store cooled soup in an airtight container in the refrigerator for up to 3–4 days.
  • Freezing: Freeze in airtight, freezer-safe containers for up to 3 months for the best quality.
  • Reheating: Warm on the stovetop over medium-low heat or in the microwave until thoroughly heated to 165°F (74°C). Add water or broth if needed.
  • Make ahead: The soup thickens as it sits and develops deeper flavors, making it excellent for meal preparation.
  • Nutrition values are approximate and calculated using vegetable broth, without optional olive oil drizzles or additional garnishes.
