Preheat the oven to 350°F.
In a large bowl, whisk everything until well blended and smooth. Pour into the crust.
Bake for 50-60 minutes, until the filling is set but still just a little wobbly in the middle and the crust is golden. If the crust is browning too quickly, cover the pie lightly with a sheet of foil as it bakes. Cool completely in the pan on a wire rack.
Serve the pie at room temperature with whipped cream, sweetened with a little sugar or maple syrup.
