Pastry burning at edge

You can cover the edges of the dish in foil before they start burning. Probably about half way through the baking.

I would say if the edges are burning, you need to reduce the oven temperature.

I agree with GrannyLaine - it sounds like the oven is too hot. Either turn it down or try putting the quiche on a lower shelf.

Thanks everyone.

You should blind bake the pastry allow to cool add the filling then bake at around 150/160 depending on your oven.
I find a fan oven better than a static for pastry.
