I made this potatoes au gratin recipe from Pioneer Woman (love her!). I did make several changes, I eliminated all of the butter, used fat-free half and half instead of the heavy cream and the milk, I added 1 tsp of dried rosemary, and I doubled the cooking time without the lid. These were ok, but not as good as I'd hoped for. However, with the butter and the heavy cream I'm sure they would be wonderful. Next time I might incorporate a little of the butter in the dish to add a little more flavor.
