- Preheat the oven to gas 6, 200°C, fan 180°C. Heat the oil in a large frying pan and cook the onion, pepper, carrot, aubergine, and mushrooms, stirring occasionally for 10 mins, until softened. Add the beef and fry for 4-5 mins until browned, breaking up the bulk with a wooden spoon.
- Add the stock pot, chopped tomatoes, and passata; season. Simmer over a medium heat, stirring occasionally for 10-15 mins, until thickened.
- Beat the eggs with the ricotta, crème fraîche, 2 tbsp Parmesan, the nutmeg and a pinch of salt, until smooth.
- To assemble the lasagne, tip half the mince into the base of a 25cm x 30cm ovenproof dish, top with 2 sheets of lasagne then spread over half the ricotta mixture. Repeat with the remaining mince, lasagne sheets, and ricotta mix, then top with the tomato slices and bake for 20 mins.
- Remove from the oven and scatter over the remaining Parmesan. Tear the prosciutto and arrange on top around the tomatoes, bake for 20 mins, until bubbling. Leave to stand for 10 mins before serving.
Little help
Divide the lasagne up into portions and freeze for easy weekday meal planning.
Leftovers
Make a light lunchtime bite, or canapes, by mixing crème fraîche with a little mustard and lemon juice, spread on crackers and top with torn prosciutto. Season, or sprinkle with chopped parsley for extra flavour.
Freezing and defrosting guidelines
Once the dish has cooled completely, transfer it to an airtight, freezer-safe container, seal and freeze for up to 1-3 months. To serve, defrost thoroughly in the fridge overnight before reheating. Loosely cover with foil and bake until dish is thoroughly heated through. Reheat until piping hot.
