If you are talking about substituting butternut or acorn squash of the pumpkin, you can use any recipe for a pumpkin pie that you like. If you are cooking the squash yourself, just make sure that you mash it up real well or puree it in a blender or food processor.

A lot of folks like the recipe on the back of the Libby's canned pumpkin. But your pie made from freshly cooked squash is going to taste way better than canned pumpkin! I would use 2 cups of your cooked and pureed squash. One ounce is not going to make a whole lot of difference.
