Gather all ingredients. Preheat the oven to 450 degrees F (220 degrees C).

Line the bottom and sides of a 9-inch pie plate with one pie crust. Lightly brush crust with egg to prevent dough from becoming soggy later. Set second crust aside.

Place peaches in a large bowl, sprinkle with lemon juice, and mix gently.

Mix together sugar, flour, cinnamon, nutmeg, and salt in a separate bowl. Pour over peaches and mix until combined.

Pour into pie crust and dot with butter.

Cover filling with remaining pie crust. Flute the edges to seal or use a fork dipped in egg to press them down.

Brush remaining egg on top, then cut several slits in the top crust to allow steam to escape.

Bake pie in the preheated oven for 10 minutes. Reduce the heat to 350 degrees F (175 degrees C) and bake until crust is brown and juice begins to bubble through the vents, 30 to 35 more minutes. If the edges brown too fast, cover them with strips of aluminum foil about halfway through baking.

Cool pie for 15 minutes before slicing. Enjoy!
