Whisk together the egg and water, then brush over the top crust.
Bake for 40–50 minutes, or until the crust is golden brown and the filling is bubbling. If the edges brown too quickly, cover them loosely with foil.
Cool for at least 1 hour before slicing.
If using the glaze, whisk together the powdered sugar, milk, and vanilla until smooth. Drizzle over the cooled pie.
Tips
A mix of tart and sweet apples creates the best flavor and texture.
Let the pie cool before cutting so the filling has time to set.
Serve warm or at room temperature with vanilla ice cream or whipped cream.
Leftovers can be covered and stored at room temperature for up to 2 days or refrigerated for up to 5 days.
