It is possible to make pumpkin pie with almost any type of squash—and butternut squash might be one of the best options. It is not too watery, and once pureed it doesn’t show any grainy or fibrous texture, making it very similar to canned pumpkin puree.  To prepare homemade puree, keep in mind that you need to bake the halves or quarters of the butternut squash beforehand, carefully removing the seeds and stringy segments.
