  1. Heat the oil in a large non-stick pan and cook the onion, garlic, carrot and celery for 5 minutes until soft, but not coloured.
  2. Add the mince and pancetta or bacon and cook until brown for 10-15 minutes, breaking down any meaty chunks with the back of a wooden spoon.
  3. Add the wine, tomato purée, nutmeg, tomatoes and water. Season and bring to the boil. Reduce the heat, cover and cook for 1 hour, stirring occasionally. Remove the lid and continue to cook uncovered for a further 30 minutes.
  4. 10 minutes before the end of the ragu cooking time prepare the Parmesan sauce. Heat the crème fraîche, Parmesan and herbs in a small pan for 3-4 minutes under a moderate heat. Season to taste.
  5. Meanwhile, cook the lasagne sheets according to the packet instructions or for 3-4 minutes in a large pan of boiling salted water, keeping the sheets separate. Drain the sheets in a colander.
  6. Assemble the lasagne on warmed plates. Start with a lasagne sheet, a few rocket sprigs, the ragu sauce and the Parmesan sauce. Repeat with two further layers of lasagne, rocket leaves and ragu sauce. Finish with 1-2 tablespoonfuls of the Parmesan sauce and garnish with extra freshly grated Parmesan.
  7. Serve immediately.
