Reduce oven temperature to 375 degrees F (190 degrees C).

Step 4
Place 2 cups of squash in a food processor and process until smooth. Add brown sugar, eggs, cream, apple pie spice, salt, and butter; process until smooth.

Step 5
Pour squash mixture into pie crust. Bake until filling rises, about 1 hour.
