This quick chicken casserole is one i call on time and time again, for the simple reasons, it is not only quick it is also easy and so delicious. This is a basic quick chicken casserole recipe and from this, you can create any kind of chicken casserole you wish. Add different vegetables or herbs; sometimes i will add small pieces of bacon, the recipe is also lovely with a few white grapes added 10 minutes before the end of cooking, which is perhaps more french than british.
