I did the same, then sprinkled cinnamon on the top of the squash just before baking. I baked covered, in a pan with about 1/2 inch of water, for one hour. They were fabulous; you could easily serve this "vegetable" as a dessert!
We were surprised by the super almost Maple syrup flavor of the squash. It was a fairly large squah so took apprx 1 hour at 375F coverrd in foil uncovered the last 15 minutes-Thanks OOlala for a neat recipe
