Buttermilk Blue Cheese Potatoes Au Gratin

Submitted by Kittencalrecipezazz

"If there is only one potato recipe you want to try, then this one has to it! it is an amazing potato dish, that will have you drooling at the table lol! This is a killer potato recipe, and one you should not pass up. Although the original recipe does not state to par-boil the potatoes, I always do this for a layered potato dish, it cooks in a much lesser time. You can use one (10-ounce) package of frozen broccoli pieces that have been steamed, in place of fresh, I have even made this dish without using the broccoli and pimento for garnish, it is still a "killer"! Make sure your buttermilk is at room temperature before using for the recipe. This buttermilk blue cheese sauce recipe can be used for a number of other recipes also."
