Prep time: 15 min
Cooking time: 35 min
  • Step 1

    Heat a little olive oil in a medium saucepan over a medium heat. Add the onion and garlic, and cook for 8-10 minutes or until soft and translucent. Stir in the celery, carrot, parsnip, and celeriac, and cook for a couple of minutes. Season with salt and pepper.
  • Step 2

    Add the bay leaf, herbs, oregano, passata, and tomato purée. Mix well and cook for 2 minutes. Cover with the vegetable stock, and gently cook until the vegetables start to soften. If necessary, top up with more stock or water as they cook.
  • Step 3

    Drain the lentils, add them to the saucepan, and simmer for 5 minutes. Add the cavolo nero and cook gently for 2 minutes, then turn off the heat.
  • Step 4

    Keep aside some of the cheese for garnishing, and add the rest to the saucepan, mixing well. Taste and adjust the seasoning if needed, and add a squeeze of lemon to taste.
  • Step 5

    Ladle the soup into two serving bowls and garnish with a sprinkle of grated cheese. This soup pairs beautifully with a hunk of rustic bread.
