When I wrote about my favorite baked butternut recipe (which is in the oven again right now...) I complained about what a pain in the rump it is to slice the skin of the squash, well, I was complaining also to my aunt and she came through with a tip! Well, apparently it came from grandma first - the wisdom of the ages.
Auntie said to put the whole squash in the oven on low heat like 250 for a few minutes until it warms up and then cut it up. Worked like a charm! Butternut sans frustration!
