Oh my my! This potato recipe is To Die For!! Took these to a holiday party & people went nuts!! Even my "loyal only to mashed potatoes" husband thought they were outstanding! A perfect combo of cheeses makes this very sinful, but oh so worth it!!!

This was superb.Very yummy.I only had cheddar cheese but I am sure the gruyere would be wonderful too. Very rich so I served it with ground turkey cooked with veg and onion-a sort of take on shepherds pie I suppose.
