I'm baking an acorn squash. How long should I bake it for?
To roast acorn squash, set your oven to 350 and roast for about 30-35 minutes.  I normally roast cut side up, unless I am using some kind of sauce to go with it.  I find that the squash cooks to a more even color than when you place it directly against a metal pan which can develop diffrent temps across the surface.

You can also baste with some butter as long as it is face up, which is pretty good.
