Step-by-Step Instructions
Step 1. Sautéing and Simmering the Soup Base
- Melt butter in a saucepan over medium-high heat. Add diced onion, a large pinch of salt, and tomato paste. Cook for 5-7 minutes until onions soften and tomato paste caramelizes.
- Add minced garlic, ground cumin, and a little cayenne pepper. Cook for 2 minutes.
- Add chicken or vegetable broth (or water). Stir and bring to a simmer.
- Add red lentils, diced celery, and diced carrot. Stir and reduce heat to medium-low. Simmer for 40 minutes, or until vegetables and lentils are tender.




Step 2. Preparing the Lemon Mint Yogurt
- Blanch mint leaves in simmering water, then quickly shock them in cold water. Squeeze out excess water and mash into a paste in a mortar and pestle with salt.
- Add lemon zest, lemon juice, and plain Greek yogurt to the mint paste. Mix well.


Step 3. Finishing the Soup
- Check the soup after about 35 minutes; lentils and vegetables should be very tender. Puree about half of the soup with an immersion blender for a creamier texture.
- Taste and adjust seasoning with salt.


Step 4. Serving the Soup
- Ladle soup into bowls. Garnish with a swirl of lemon-mint yogurt and a pinch of finely sliced mint.
