This recipe is an internet find and the delicious flavor surpassed my expectations. Try to use potatoes of equal size if possible for best results.

I've made this recipe twice now for different company, and both times it was enjoyed by all. This one is a keeper. Thankyou FlemishMinx for posting.

Pretty good. I'm a true potato LOVER and I think it's missing something...with 'bulk'. (Like cheese?) Although that wouldn't help the "low-cal health factor". I guess I just expected a more HEARTY potato dish after reading the recipe. I also thought the bread crumbs seemed out of place in this recipe. Maybe if I just used less of them next time. (?) I may try it again with some adjustments.

This came out really nice and was very tasty. I had to cook it an additional 10 minutes because it wasn't very hot and bubbly after 20 minutes. For the mustard, I used recipe #70193. We eat alot of potatoes at our house, so I'm always looking for different ways of cooking them. Thanks!
