Place strips of foil around the edges of the pie crust to prevent them from burning. Cut two or three 1-inch slits in the top of the crust as vents. Set the frozen peach pie on a baking sheet and place it on the oven’s center rack. Bake the pie at 425 degrees Fahrenheit for 15 minutes. Lower the heat to 350 degrees Fahrenheit for the rest of the baking process. Remove the foil strips from around the crust edges 15 minutes before the pie is fully baked.
