Preheat the oven to 200ºC / 400ºF / Gas Mark 6, 15 minutes before cooking. Cook the beef and
pancetta in a large saucepan for 10 minutes, stirring to break up any lumps. Add the onion, celery
and mushrooms and cook for 4 minutes, or until softened slightly. Stir in the garlic and 1
tablespoon of the flour, then cook for 1 minute. Stir in the stock, herbs and tomato puree. Season
to taste with salt and pepper. Bring to the boil, then cover, reduce the heat and simmer for 45
minutes.
Meanwhile, melt the butter in a small saucepan and stir in the remaining flour, mustard powder
and nutmeg, until well blended. Cook for 2 minutes. Remove from the heat and gradually blend in the
milk until smooth. Return to the heat and bring to the boil, stirring, until thickened. Gradually
stir in half the Parmesan and Cheddar cheeses until melted. Season to taste.
Spoon half the meat mixture into the base of a large oven proof dish. Top with a single layer of
pasta. Spread over half the sauce and scatter with half the cheese. Repeat layers finishing with
cheese. Bake in the preheated oven for 30 minutes, or until the pasta is cooked and the top is
golden brown and bubbly. Serve immediately with crusty bread and a green salad.
