This was incredibly good! I made this exactly as posted, except I halved the recipe and cooked it in a 9-inch-square pan. I used my mandolin to slice the onions and potatoes really thin. I did not use the bread crumb topping either, but did sprinkle some parsley on the potatoes for color. The potatoes smelled heavenly, they were so tender and delicious! I think this would be wonderful for a holiday dinner, or any meal that you want to spruce up. Thanks for sharing this keeper! Made for Spring PAC 2011.
