The Best Lentil Soup

Step 1

Heat the oil in a large heavy-bottom pot over medium-high heat. Add the carrot, onion, celery and 1 teaspoon salt and cook, stirring occasionally, until the vegetables are starting to caramelize and take on a dark brown color, 8 to 10 minutes (this step is important as it will add tons of flavor to your soup!).

Step 2

Stir in the tomato paste and garlic and cook, scraping up the brown bits, until the garlic is fragrant and slightly softened, 1 to 2 minutes. Add in the lentils, stock, 4 cups water, thyme, bay leaf, oregano, red pepper flakes, lemon zest, 2 teaspoons salt and a generous amount of black pepper and stir to combine. Bring to a boil then reduce the heat to low. Cover and cook until the lentils are softened with just a bit of bite, 25 to 30 minutes.

Step 3

Remove the bay leaf. Puree 2 1/2 cups of the soup in a blender until smooth then stir back into the pot. Stir in the lemon juice and parsley. Ladle into bowls and garnish with more parsley.
