Preheat the Oven: Preheat your oven to 375°F (190°C).
Prepare the Filling: In a large bowl, combine sliced peaches and lemon juice. In a separate bowl, mix together sugar, flour, and cinnamon. Gently toss the flour mixture with the peaches until well coated.
Assemble the Pie: Roll out the pie crust and place it in a 9-inch pie pan. Pour the peach filling into the crust, spreading it evenly. Fold the edges of the crust over the filling, leaving some peaches exposed.
Brush and Sprinkle: Brush the crust edges with half-and-half and sprinkle sugar over the top.
Bake: Bake in the preheated oven for 55 minutes, or until the crust is golden brown and the filling is bubbly.
Cool and Serve: Remove from the oven and let it cool for a bit before slicing. Serve warm, ideally with a scoop of vanilla ice cream.
