This Chicken, Apple, and Cheese Casserole is outstanding! The combination of apples and Swiss cheese is lovely, and preparation is easy. Use Jonagold apples—or, any other variety firm enough to hold up when cooked.
Preheat the oven to 350 degrees F. Coat a 2-quart baking dish with 1 tablespoon of the butter.
Melt the remaining 4 tablespoons butter in a large heavy skillet over medium heat. Add the apples and onions and saute until the apples are tender, about 10 minutes. Spoon into the baking dish.
Rub the chicken with the salt and pepper and arrange over the apple-onion mixture. Combine the cheeses with the bread crumbs and thyme and sprinkle the mixture over the chicken. Drizzle the brandy over the cheese. Bake for 35 minutes or until the cheese is golden brown and the chicken is done.
