"This is a staple potato recipe in my family that all love!! Some recipes call for added oil or the butter, but keep in mind, the cheese has a lot of oil so that's usually plenty!! Soooo very tasty and yummy!! This is a good alternative when you're tired of mashed potatoes, stuffing or others!! To get a crispy topping, take the foil off towards the end of baking! To make it more like a cutted square casserole per serving, add an egg to stiffen it up like you would lasagna. Definitely try this if you've never had these!!"
