Toss apples with sugar, flour, lemon juice, spices and salt.
Make pie crust bottom by rolling out half the pie dough into a 12” circle. Gently drape the dough into a 9” pie plate. Transfer apples into the bottom pie crust. Roll out the remaining dough and lay it on top of the apples. Seal and crimp the edges.
Brush the top crust with beaten egg and sprinkle with coarse sugar, if desired. Use a sharp knife to slice a few small incisions for steam vents in the top of the pie. Transfer pie to freezer until firm.
Meanwhile, preheat a baking sheet on the bottom rack of the oven at 500ºF for 30 minutes.
Reduce oven temperature to 425ºF and bake the pie on top of the preheated baking sheet for 25 minute. Reduce temperature again to 350ºF and bake for 30-40 minutes more, until the filling is bubbling in the centre vents.
*Cover the pie with aluminum foil or parchment paper if at any point during baking the crust is getting too dark.
