Preheat oven to 375 degrees F (190 degrees C; gas mark 5).
Remove one pie crust disk from the fridge, unwrap it, and place it on a work surface. Roll out the disk from the center outward, lifting crust slightly and rotating it 90 degrees after every few rolls. Lift and dust underside with flour every so often to prevent the pie crust from sticking. Roll dough out to be about 11 to 12 inches, and about ⅛" thick.
With your rolling pin, roll pie crust off the work surface to loosely wrap around the pin and carefully it roll out into the pie dish. Trim the edges to ½ inch beyond the lip of your pie dish, then turn the edge under to create the rim. Press the rim against the pan to form an even edge. Use scraps to fill in any tears, thin spots, or holes in the pie crust. Refrigerate the pie crust for 15 minutes to chill the fats.
Remove the crust from the fridge and cover the crust with a large piece of parchment paper. Fill the parchment paper with dried beans or pie weights, then cover the edges with strips of aluminum foil to prevent browning. Bake for 20 minutes.
Remove the parchment paper and pie weights and bake for 15 more minutes. This is pre-baking the crust so it won't be soggy once your apple pie is fully baked. Let it cool for 10-15 minutes.
Raise oven temperature to 425 degrees F (220 degrees C; gas mark 7).
While baked crust is cooling, roll out the second pie crust on a floured work surface.
Add the apple filling to the pie dish, making sure to compact the apples into the crust in the pie dish, as air pockets will cause a gap in between the apples and the top crust. Place the rolled out second crust over the top, then crimp the edges with your fingers to seal the top crust to the bottom.
Whisk the egg and cream together in a small bowl, then brush that egg wash over the crust. Sprinkle raw sugar over the crust as well. Using a sharp knife, cut some slits into the top crust to give the steam a place to escape. Disregard if you are doing a pattern.
Place pie on a baking sheet to ensure any bubbling filling doesn't burn onto your oven, then put in the oven on the middle shelf. Bake the pie for 15 minutes and check to see if the edges are browning faster than the rest of the crust. If so cover the edges with a crust protector or carefully cover the edges with a strip of aluminum foil.
Reduce heat back to 375 degrees F (190 degrees C; gas mark 5) and continue to bake for 40 minutes. The top should be golden brown and the filling bubbly.
Let apple pie cool completely (2-3 hours) before serving to let the filling set up. Serve with vanilla ice cream.
