Potatoes and cheese. Who wouldn't love a dish like this one? I make my recipe with raw potatoes so technically this is more of a gratin dauphinoise. Still, it does have a nice cheesy crust indicative of a gratin and a creamy base.

Thinly sliced potatoes are a must especially since they are not pre-cooked. You can buy a cheap mandoline slicer for this. I think it's worth the small investment.

My sauce is made up of a roux to start with equal parts of butter and flour cooked first. Whole milk is added to the roux to make a sauce similar to my tuna noodle casserole dish.

However, this one goes a step further adding grated sharp cheddar cheese and a little salt and pepper to create a delicious creamy cheese sauce.

Two layers of potatoes and the cheese sauce are spread in a buttered casserole dish.

More cheese is added on top.

It comes out nice and crusty on the sides and crispy on top.
