Apple Upside-Down Pie

Preheat oven to 400 degrees. Peel, core and cut each apple into 12 wedges. Place butter and brown sugar in an 8-in. baking pan. Place in oven until butter is melted. Stir mixture; return it to the oven for 6-7 minutes. Remove. Stir and spread evenly over bottom of pan. Arrange apples evenly over butter mixture. Unfold the puff pastry; place on top of apples. Holding pastry down and using a spatula, push the edges down between the apples and baking dish. With the tip of a knife, poke a hole in the center of pastry. Bake 40 to 45 minutes or until pastry is golden brown. Cool completely on a wire rack
