  • 1 tablespoon olive oil
  • 4 medium carrots, peeled and chopped (about 1 ½ cups)
  • 1 large sweet onion, chopped
  • 2 cloves garlic, minced
  • ¼ teaspoon crushed red pepper flakes (more or less to taste)
  • 2 teaspoons fresh thyme leaves (or ½ teaspoon dried)
  • 4 cups vegetable broth
  • 1 cup water
  • cup dry red lentils, rinsed
  • cup dry green or Puy lentils, rinsed
  • 1 (6-ounce) can tomato paste
  • 1 tablespoon brown sugar
  • 1 tablespoon white vinegar
  • ½ teaspoon garam masala
  • 1 teaspoon fresh ground black pepper
  • 3 cups kale leaves, stems removed, cut into bite size pieces
  • 2 tablespoons minced fresh parsley


  • Pour the olive oil in a large Dutch oven or soup pot. Heat on medium-high until the oil is shimmering. Add the carrots and onion. Sauté for 5 minutes, or until the vegetables are crisp-tender. Add the garlic, crushed red pepper and thyme leaves. Sauté until the garlic is fragrant, about 1 minute.
  • Add the vegetable broth, water and lentils to the pot. Bring to a boil. Reduce the heat, cover and simmer for 25 to 30 minutes.
  • Add all remaining ingredients: tomato paste, brown sugar, vinegar, garam masala, pepper, kale and parsley. Return the soup to a boil, then reduce the heat and cook, uncovered, for 10 minutes or until the kale is wilted.
  • Serve with a dash of hot sauce, if desired. Garnish with parsley.


We like the spark of heat from the crushed red pepper. If you don't care for the warmth, start with 1/8 teaspoon or omit.
Use low-sodium vegetable broth, if desired. Also you can use salt-free or low-sodium tomato paste in this recipe. Check the seasoning to ensure you don't need a little salt.
