This easy potatoes au gratin recipe is the perfect side dish for any meal. Something the cheese lovers will enjoy and a great dish to bring to the party.
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.
Potatoes Au Gratin FAQs
I like a starchy potato such as a russet potato. However, you might also like a waxy potato like a red potato because it holds its shape better.
Yes, we really love sharp cheddar cheese but you could try Gruyere or Swiss. You could even mix a few together or add a little extra Parmesan, blue, or feta in to add even more flavor.
Yes, many people use heavy cream in their recipe. However, I don't think it is necessary and the roux makes the sauce nice and creamy.
This yummy potato casserole dish is a crusty, cheesy, and creamy side dish that will surely get devoured by everyone who tries it. In fact, you might just want to make two because it tastes just as good days later.
