Bake 15 minutes.
Reduce oven to 350°F; continue baking 20 to 22 minutes or until knife inserted midway between center and edge of pie comes out clean.
When is it done? Like custard pies, pumpkin pie should be removed from the oven before the center is completely set. The center will jiggle slightly when dish is gently shaken. Filling will continue to "cook" after it's removed and center will firm up quickly. The knife test: Test for doneness with a thin-bladed knife. If knife is clean when pulled out, the custard is done. If any filling clings to the blade, bake a few minutes longer and test again.
