Instructions

  1. Step 1: Dice 4 ounces pancetta into small cubes and heat 2 tablespoons olive oil in a large Dutch oven over medium heat. Cook pancetta for 5-6 minutes until crispy and golden, then remove with a slotted spoon and set aside.
  2. Step 2: Finely dice 2 medium carrots, 2 celery stalks, and 1 medium yellow onion. Mince 3 garlic cloves. Add vegetables to the pancetta fat in the pot and sauté for 8-10 minutes until softened and fragrant.
  3. Step 3: Rinse 1 cup green lentils under cold water and add them to the pot along with 6 cups chicken broth, 1 teaspoon dried thyme, 1 bay leaf, and 1/4 teaspoon crushed red pepper flakes. Bring to a boil, then reduce heat and simmer uncovered for 35-40 minutes until lentils are tender.
  4. Step 4: Remove the bay leaf. Stir in the reserved pancetta, season soup with salt and black pepper to taste, and sprinkle 1/2 cup freshly grated Parmesan cheese. Stir until cheese melts slightly.
  5. Step 5: Serve hot, garnished with 2 tablespoons chopped fresh parsley.
