Using a rubber spatula, transfer the filling to the prepared pie plate.

Bake until the center appears set and a toothpick inserted in it comes out just a little moist and free of batter, about 75 minutes. Check the pie after 45 minutes and loosely tent the edges with strips of foil if they seem to be getting too dark.

Cool the pie 2 hours on a cooling rack, then cover with plastic wrap and refrigerate 2 hours before slicing and serving.
