I'm baking an acorn squash. How long should I bake it for? I'm baking an acorn squash. How long should it bake for and at what temperature? I also noticed on the spaghetti squash question that those are baked sliced face down. Should acorn squash bake face down too?
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.
