Step 1: Prepare the pie dough. Chill for at least one hour or follow store-bought directions.
Step 2: Preheat oven to 400°F (204°C). Place a baking sheet inside while heating.
Step 3: Make the filling: mix apples, sugars, flour, spices, lemon juice, and zest until evenly coated.
Step 4: Roll out the bottom crust and fit it into a deep-dish pie plate.
Step 5: Add the apple filling evenly, leaving out excess juice.
Step 6: Roll out the top crust and place over the filling. Trim and crimp the edges.
Step 7: Cut 4 slits in the top crust to vent steam. Optional: make a lattice top.
Step 8: Brush with egg wash and sprinkle sanding sugar, if desired.
Step 9: Bake on the preheated sheet for 25 minutes. Shield crust edges if needed.
Step 10: Lower heat to 375°F and bake for 30–35 more minutes until golden and bubbling.
Step 11: Cool at room temperature for at least 3 hours before serving.
