Bring the pie crusts up to room temperature, and preheat the oven to 375 degrees.

Press one pie crust round into a 9 inch pie plate.

Mix the apple slices, sugar, flour and cinnamon in a medium sized bowl.

Pile the apple mixture into the pie crust. The apples will mound above the level of the pie crust, but they’ll shrink as they cook.

Put the top crust over the apples and pinch the pie crusts together to form a decorative crust. You may have to trim some excess pastry dough. Cut slits in the top of the pie crust to let the steam escape.

Cover the edges of the pie with foil and bake at 375 degrees for 25 minutes. Remove the foil and bake for an additional 25-30 minutes.
