If you make this dish for Thanksgiving or Christmas, you can roast the potatoes in advance. You can assemble the dish the night before and refrigerate it until the next day when you bake it, or you can bake it the day before and then reheat it in the oven. Note: These roasted sweet potatoes are not crisp, but they are not mushy either. The orange juice gives them flavor and enough moisture to still have texture but also melt in your mouth.
