Whisk all the ingredients together in a large bowl and pour into the prepared, cooled pie crust.
Lightly tent the pie with tinfoil so the crust doesn't further brown and place into the oven. Bake until the center just has a little jiggle, and a knife inserted an inch from the crust comes out clean, about 45-50 minutes. Turn the oven off, crack the oven door and let the pumpkin pie sit inside for 30 minutes.
After 30 minutes, let the pie cool on the counter COMPLETELY for 2 hours, then refrigerate for at least 1 hour. *
Serve with sugar free whipped cream (if desired) and DEVOUR!
*The pie CAN be served at room temperature, but the crust is a little flakier and better if its refrigerated and served right from the refrigerator.PIE CRUST RECIPE
