Instructions

  1. Step 1: Rinse 1 cup dry green lentils under cold water until clear. Heat 2 tbsp olive oil in a large pot over medium heat. Add 1 diced medium onion, 1 large diced carrot, 2 diced celery stalks, and 3 minced garlic cloves; sauté for 5-6 minutes until vegetables soften and become fragrant.
  2. Step 2: Stir in 1 tsp ground cumin and 1/2 tsp smoked paprika; cook for 1 minute until spices release their aroma.
  3. Step 3: Add rinsed lentils and 4 cups vegetable broth to the pot. Bring to a boil, then reduce heat to low and simmer uncovered for 25-30 minutes until lentils are tender.
  4. Step 4: Stir in 4 cups fresh spinach leaves and cook for another 3 minutes until wilted.
  5. Step 5: Season with 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp lemon juice. Adjust seasoning to taste and serve warm with crusty bread or over rice.
