Preheat oven to 425°F (220°C).

Peel and slice the apples.

In a mixing bowl, combine apples, sugar, flour, cinnamon, nutmeg, and lemon juice.

Roll out one pie crust to fit the pie dish.

Place the apple mixture into the crust.

Dot the apple filling with pieces of butter.

Roll out the second pie crust and cover the filling.

Seal the edges of the crust by crimping.

Cut slits in the top crust for steam to escape.

Bake in the preheated oven for 15 minutes, then reduce the temperature to 350°F (175°C) and bake for an additional 30 minutes.

Let the pie cool for at least an hour before slicing.
