Hash Brown Egg Casserole with Ham and Cheddar

Hash brown egg casserole combines a potato base with a soft egg filling and pockets of ham and cheese. Browning the potatoes first gives the base more flavour than adding wet thawed shreds directly to the dish. Mushrooms need their moisture cooked away for the same reason. The finished centre should hold when cut, with no raw egg pooling at the slice. Resting for ten minutes makes cleaner portions and gives the cheese time to settle.
