1Combine all brine ingredients. Put into a gallon size freezer bag with chicken. Put in fridge( turning occasionally) until you want to cook it. The first time I marinated it for 24 hours. This time is 48 hours.
2Preheat oven to 400. Peel & slice potatoes about 1/4 inch thick. Rinse & pat dry chicken, remove skin if desired.Put chicken in one side of 13x9 baking pan, after seasoning with garlic salt & Italian seasoning both sides. Layer potatoes with butter slices, seasonings& cheese in other side. Add butter slices on chicken also when you get to the last layer of potatoes. Put Parmesan cheese over all.
3Cover with foil, and bake for 45 min.
4Uncover and bake 15 min. To brown top.
(May use chicken breasts also. If using boneless chicken, reduce heat to 375.)
