Peel and dice the parsley roots, potatoes and carrots. Heat the oil and sauté the diced vegetables a little. Deglaze with vegetable stock and add milk. Cook the vegetables until soft in 10-15 minutes. Purée finely with the hand blender and season with salt and pepper. Fill into plates and garnish with grated carrot.
Tip: You can also add a few croutons, fried bacon cubes or 2 fried prawns to the soup.
