Ole Lady asked about how I roast butternut squash. Here is my method.
I line a large sheet pan with parchment and pre-heat the oven to 375F.
I wash the squash. I cut off the bottom, so that I have a flat place to start cutting. I use a Kuhn-Rikon knife that was marketed for cutting pumpkins. It has jack-o-lantern cut outs on the knife, which is not what helps it cut, and which actually makes cleaning it more difficult, as I need to get squash threads out of the cut-outs. What makes it great for this use is the wide, sawtooth blunt tip blade. It goes through the thick skins of pumpkin and butternut squashes very well.
I cut it in half lengthwise. Then I use a grapefruit spoon to scoop out the seeds and pulp. There is a lot less than in a pumpkin--just down at the bottom--so this goes fast.
I then put the squash cut-side down onto the parchment-lined baking sheet. I roast it at 375F for an hour, or longer, until I can push down on the skin and know that the interior is soft.
I remove it from the oven, and turn the squash over. I let them cool a bit, then I scoop out the squash and run it in the food processor.
I hope that helps! Butternut squash is now one of my favorites.
