A golden peach pie filled with sweet, juicy summer peaches is a Southern family dessert tradition. This fragrant, fresh pie is best enjoyed warm with a scoop of vanilla ice cream.
Preheat the oven to 425°F (220°C) and position a rack in the lower third for optimal heat distribution.
Toss sliced fresh peaches with granulated sugar, flour, lemon juice, salt, and ground cinnamon in a large bowl until evenly coated.
Line a 9-inch pie dish with one prepared crust, pressing gently so it fits snugly, then pour in the peach filling and dot the top with unsalted butter.
Cover with the second pie crust, crimping edges firmly and cutting several vents in the top to allow steam to escape; brush with milk or beaten egg if desired for extra color.
Bake for 20 minutes at 425°F, then reduce heat to 350°F and bake an additional 30–35 minutes until the crust is golden and the filling is bubbling; cool for at least 1 hour before serving for best texture.
