Preheat oven to 425°F (220°C). Place one pie crust into a 9-inch glass pie plate, pressing it firmly against the sides and bottom.
In a large bowl, combine the sliced apples, granulated sugar, flour, cinnamon, salt, nutmeg, and lemon juice. Toss gently to coat the apples evenly.
Pour the apple mixture into the crust-lined pie plate, mounding it slightly in the center.
Place the second crust over the apple filling. Fold and tuck the excess top crust under the edge of the bottom crust, pressing them together to seal. Flute the edges as desired.
Cut several small slits in the top crust to allow steam to escape during baking.
Bake the pie for 40 to 45 minutes, or until the crust is golden brown and the apples are tender. To prevent excessive browning, cover the edge of the crust with 2- to 3-inch-wide strips of foil after the first 15 to 20 minutes of baking.
Once done, remove the pie from the oven and place it on a cooling rack. Allow it to cool for at least 2 hours before serving to let the filling set properly.
