Heat your oven to 425°F and allow your chilled pie dough disks to soften slightly at room temperature, making them easier to roll out.
02 -
Create shallow cuts on the bottom of each peach, then carefully remove the skin. Cut peaches in half, discard the pits, and slice into half-inch thick pieces.
03 -
Combine sliced peaches with sugar, cornstarch, lemon juice, vanilla, and cinnamon in a large mixing bowl. Gently toss everything together and let it rest while you prepare the crust.
04 -
Roll one dough disk into a 13-inch circle, keeping it about ⅛-inch thick. Carefully transfer to your 9-inch deep-dish pie pan, allowing excess dough to drape over the edges.
05 -
Roll the second dough disk into an 11-inch circle, then cut into 1-inch wide strips. You'll need about 8 to 10 strips for a beautiful lattice pattern.
06 -
Spoon the peach mixture into the prepared bottom crust, creating an even layer. Scatter the cold butter cubes across the surface of the fruit.
07 -
Weave the dough strips over and under each other to form a classic lattice pattern. Trim both the lattice ends and bottom crust to leave a 1-inch overhang, then fold under and crimp the edges decoratively.
08 -
Whisk the egg with 1 tablespoon water to create an egg wash. Brush this over the lattice and crust edges, then sprinkle with coarse sugar for a golden finish.
09 -
Cover the pie edges loosely with aluminum foil and bake for 20 minutes at 425°F, then reduce temperature to 375°F for the remaining baking time.

Continue baking for 40-50 minutes more until the crust is golden brown and filling bubbles vigorously throughout. Cool completely on a wire rack for 4-5 hours before serving to allow the filling to set properly.
