Wow--baked butternut squash!
So I just discovered baked butternut squash...a little oil and cinnamon go a long way. I often bake sweet potatos this way...are there any other squash varieties or veggies/roots that are this easy and delicious?
If you roast some garlic and maybe and onion along with that butternut, and then puree the lot, you'll have a great soup. So much easier than peeling and cubing raw butternut.
Try other flavours - orange/lemon zest, curry. Epicurious has some nice suggestions.
You can try roasting carrots similarily. They shrink quite a bit, but a bit of oil and brown sugar make them delicious. Just keep an eye on them, as they don't take that long, and you don't want the sugar to burn them black. And beets, of course, are lovely too.
Oven roasted onions are great as well. take red onions, make a cross in the top, and smoosh some herbed butter into the gap. mmmm...
