Roll out the pastry, line a 23 cm tart tin, prick the base and chill 15 minutes.
Blind-bake the shell at 190 C for 15 minutes, then remove the weights.
Fry the bacon and onion until golden and spread over the pastry base with the grated cheese.
Whisk the eggs, cream, milk, nutmeg, salt and pepper into a smooth custard.
Pour the custard into the shell over the filling.
Bake at 180 C for about 30 minutes until the centre is just set and the top is golden.
Cool 10 minutes so it firms up, then slice and serve warm.
