Roasted Butternut Squash Soup

I have made many butternut squash soups in my day. This time I decided to try roasting the butternut squash instead of the way I usually cook it (by pealing and boiling it).

I started by cutting the butternut squash in half

then scooped out the seeds and dropped a little scoop of butter where the seeds used to be and laid fresh rosemary on each squash.
