Bake in preheated oven for 35 to 40 minutes, or until knife inserted into centre of quiche comes out clean. If necessary, cover edge of pastry with foil while baking to prevent burning or overbrowning. Let stand for 10 minutes before serving.
This is about the best quiche recipe I've tried - The base stayed nice and crispy while the filling was moist and tasty, without being too liquid. Looked great, tasted great. Only quibble - I like my filling to have a bit of fresh basil or thyme, but that's easily taken care of.
I am a big fan of quiche becuse of its simplicity and wonderful flavours and have tried many recipes. This one includes too much liquid (we should reduce the amount of milk) which requires a longer cooking time and also to bake the pastry crust before hand or it would turn soggy. So much milk also makes it taste bland.
