Ingredients

For the Soup

  • 1 medium-sized onion, chopped
  • 1 1/4 cups red lentils, picked over and rinsed
  • 3 cloves garlic, minced
  • 1 small potato, cut into 1-inch cubes
  • 1 large carrot, chopped (approximately 1/2 cup)
  • 8 cups vegetable stock or a combination of water and stock
  • 2 teaspoons salt
  • 1/2 teaspoon black pepper

Optional Toppings

  • 2 tablespoons Italian parsley, chopped
  • 1 cup croutons
  • Lemon wedges
  • 1 tbsp sumac
  • Pinch of Aleppo pepper, Urfa chili, or red pepper flakes

Optional Butter Drizzle

  • 4 tablespoons salted butter (half a stick)
  • 1/2 teaspoon cayenne pepper or Aleppo pepper

Instructions

  1. Prepare Ingredients: Chop the onion, garlic, potato, and carrot; rinse and pick over the red lentils to remove debris.
  2. Combine and Cook: In a medium heavy-bottom pot, add onion, red lentils, garlic, potato, carrot, and pour in 8 cups of vegetable stock. Bring to a boil over medium-high heat, then reduce to low and simmer for 10-15 minutes until lentils, potatoes, and carrots are fully softened. Check doneness by inserting a knife into the vegetables; it should slide in and out easily.
  3. Puree the Soup: Remove the pot from heat and blend the soup until smooth using an immersion blender directly in the pot or transfer in batches to a food processor or blender.
  4. Reheat: Return the pureed soup to the stove, bring it to a gentle boil again, then taste and adjust seasoning with salt and pepper as needed.
  5. Prepare Optional Butter Drizzle: In a small skillet over low heat, melt 4 tablespoons of salted butter, cooking until lightly browned. Stir in 1/2 teaspoon cayenne pepper or Aleppo pepper, then remove from heat.
  6. Serve: Ladle the hot soup into bowls, drizzle with the spiced browned butter if using, and garnish with chopped parsley, croutons, lemon wedges, and a sprinkle of sumac or red pepper flakes if desired. Serve immediately.

Notes

  • Adjust soup consistency by modifying the liquid quantity in half-cup increments for thicker or thinner texture.
  • Leftovers should be cooled to room temperature and stored in an airtight container in the refrigerator for up to 4 days.
  • To freeze, cool the soup to room temperature, place in airtight containers, and freeze for up to 2 months.
  • Thaw frozen soup in the refrigerator overnight and reheat gently on the stovetop before serving.
  • The butter drizzle enhances flavor and provides a traditional finishing touch but can be omitted for a lighter dish.
