Yup. I was kind of surprised myself. With the foil on top, it wasn't even brown on top at all until I took the foil off.

By the way, just by dumb luck, I ended up layering the sweet potatoes on the very top of the casserole, which made the top look prettier than if the regular potatoes had gone on top. Next time I think I would put a lot more cheese on top and I would put in some minced onion. I actually didn't really taste the rosemary in the crust.
