Lasagna Bolognese

Bolognese sauce: cut pork and beef into cubes and the pancetta into thin strands. Chop the carrots, celery and onion. In a pan, brown the meat in olive oil. Do it in batches so as not to overload the pan. Drain the excess fat and set aside. In the same pan, add the chopped vegetables until soft. Add the thyme, rosemary and wine. Let wine reduce to a quarter, then return the meat, tomatoes and enough water to cover the meat. Cook over a very low heat or inside the oven at 150C, lid on, for around 2h30min. The sauce is ready when it’s thick and the meat is falling apart. Béchamel sauce: mix the soft butter and flour to form a paste and chill. Heat the milk in a saucepan and add the butter+flour. Stir until melted, boil until thickened and season. Cook the lasagna sheets according to the manufacturer’s instructions and assemble:in a greased ovenproof dish, line at least 3 layers of noodles, bolognese sauce, béchamel and sprinkle each with parmesan. Bake until golden in a 200C/375F oven.
