Equipment

  • 5–6 quart Dutch oven or heavy soup pot with lid
  • Wooden spoon
  • Immersion blender

Ingredients

  • 3 tablespoons extra-virgin olive oil divided (1 tbsp for sauté, 2 tbsp to finish)
  • 1 medium yellow onion small diced
  • 2 medium carrots small diced
  • 2 celery ribs small diced
  • 1 tablespoon tomato paste no-salt-added, if available
  • 4 garlic cloves minced
  • 2 teaspoons ground cumin
  • 1 teaspoon dried oregano
  • 1 teaspoon ground coriander
  • ½ teaspoon smoked paprika sweet or mild
  • 1 bay leaf
  • ½ teaspoon fine sea salt plus freshly ground black pepper to taste
  • 1 28-ounce can no-salt-added fire-roasted diced tomatoes
  • 7 cups no-salt-added vegetable broth
  • cups dry brown or green lentils rinsed
  • 4 large kale leaves stems removed, leaves thinly sliced
  • 1 large lemon juiced (about 3 tablespoons), plus extra wedges for serving
  • 2 tablespoons chopped flat-leaf parsley optional
  • Pinch Aleppo pepper optional

Instructions

  • Warm & Soften : Heat 1 tablespoon olive oil in a Dutch oven over medium heat. Add onion, carrots, and celery with a pinch of salt and pepper. Cook, stirring, until the onion turns translucent and the vegetables soften slightly, 6 to 7 minutes. If the pot looks dry, add a splash of water instead of more oil.
  • Toast & Bloom : Stir in tomato paste and garlic; cook until the paste deepens in color, 1 minute. Sprinkle in cumin, oregano, coriander, smoked paprika, and add the bay leaf. Toast the spices until aromatic, 60 to 90 seconds.
  • Deglaze : Pour in a small splash of broth and scrape up any browned bits.
  • Simmer to Tender : Add the remaining broth, diced tomatoes, and lentils. Bring to a simmer, then reduce heat to low and partially cover. Cook, stirring once or twice, until the lentils are tender but still hold their shape, 22 to 25 minutes.
  • Spot-Blend for Body : Remove the bay leaf. Using an immersion blender, blend in one corner of the pot for 5 to 10 seconds to slightly thicken while keeping most lentils intact.
  • Green Finish : Stir in the kale and simmer until just wilted and bright, 2 to 3 minutes. Off the heat, add lemon juice. Taste and season with black pepper and a small additional pinch of salt only if needed.
  • Serve : Ladle about 1½ cups into bowls. Drizzle the remaining 2 tablespoons olive oil evenly over portions, then finish with parsley and a tiny pinch of Aleppo pepper, if using. Serve with lemon wedges.

Notes

Serving & Storage: Keeps up to 5 days refrigerated in an airtight container or up to 3 months frozen. The soup thickens as it rests; loosen with hot water or additional no-salt-added broth when reheating.
