Place frozen pie shell on a baking sheet and set aside.
In a medium bow, whisk together all other ingredients till smooth.
Pour the pumpkin filling into the shell. Carefully transfer the baking sheet to the oven and bake for 65 minutes.
The middle of the pie will still slightly jiggle when you remove it from the oven. If it appears to liquidly allow it to bake for an additional 5-10 minutes.
Remove pie from oven and allow to cool to room temperature before slicing.
