This pumpkin pie will take around 50 to 60 minutes to bake, you should start checking it at around 45 minutes to be sure that it doesn't over bake. I test my pumpkin pie by giving it a little wiggle, it should not move at the edges but have a very slight jiggle in the middle, similar to a baked cheesecake. It should be set on top, but take it out of the oven when you still have that little wobble in the center as it will continue to cook as it cools. You can also insert a knife near the center, and if it comes out clean it's ready. This will leave a mark in the pie, but it's easily covered with some whipped cream. You can over bake pumpkin pies, cracks may appear on the surface, small bubbles may appear and the filling will start to pull away from the pastry case. If you see any of these signs, take it out of the oven straight away.
