Add the other pie crust to the top and crimp the pie closed.

Beat the egg and add the water to make an egg wash. Using a pastry brush, apply a coat of egg wash to the top crust. Make a few slits in the dough to allow the steam to escape while cooking.
1 Egg, 2 tsp Water
Place the leftover thanksgiving pie on a foil-lined baking sheet and place it into the oven.
Bake for 40-45 minutes until the crust is a nice golden brown.
Remove the pie from the oven and allow it to cool for at least 15-20 minutes before slicing.
Serve and enjoy!
