Set the oven temperature to 425°F (220°C).
Cut peaches, sugar, flour, nutmeg, cinnamon, salt, and lemon juice in a big mixing basin.
Stir until the peaches are coated all the way. One pie crust should be rolled out and put into a pie dish.
Fill the pie crust with the peach filling. Put tiny bits of butter all over the filling.
Lay the second pie crust, rolled out, on top of the filling. To seal the pie, trim off any extra dough and crimp the edges.
Make indentations in the upper crust to release steam.
Optional: To get a golden finish, brush the upper crust with milk or egg wash. To prevent spills, put the pie on a baking sheet and bake it for 45 to 50 minutes, or until the crust is golden brown and the filling is bubbly.
Allow the pie to cool for at least 2 hours before serving to allow the filling to set.
