This was our potato side dish we had with the Sunday roast chicken, I halved the recipe but not the onion amount, it worked.It made a nice change to our regular roast potatoes, richer but a real treat and will make this again! Thanks for posting.

This is a really great recipe, easy to make and a different twist on regular au gratin potatoes. We loved it. I did half the recipe and it still makes quite a large dish. Thanks for the recipe.

This was tasty and went together quickly using my mandoline slicer. I used 1% milk instead of 1/2 and 1/2. Thanks for posting!
