Creamy Potatoes Au Gratin

My family is a meat and potatoes kind of bunch so I make several different kinds of Au Gratin potatoes. I think my personal favorite is my Creamy Potatoes Au Gratin because it’s so cheesy! The sauce is velvety and thick and it coats every bite of the potatoes. Just thinking about it nearly makes me weak in the knees!

Creamy Potaotes Au Gratin is a rich, delicious side dish your family will love!

I like to make this dish extra rich so I use part milk and part half-and-half for the sauce. And, of course, there’s plenty of cheddar cheese! Mr. Comfortable really likes the crunchy breadcrumb topping so I always add that. The truth is we all love that topping!

Making Creamy Potatoes Au Gratin takes a few steps but it’s absolutely worth it! First I preheat the oven to 400 degrees. Then I slice up 5 or 6 nice size russet potatoes. I layer about half of them in a buttered 1 1/2 quart casserole dish. I season them with 1/4 teaspoon salt and 1/4 teaspoon pepper.

Potatoes layered with thick, creamy cheese sauce make Creamy Potatoes Au Gratin extra special!

In a medium saucepan over medium heat I melt 4 1/2 tablespoons of butter.

I add the flour and a half teaspoon of the salt to the butter and whisk it for one minute over the medium heat.

Next I slowly pour the half-and-half and milk (which I’ve combined) into the flour mixture. I stir this frequently while it thickens. This takes several minutes.

Once the milk mixture has thickened I add the cheese all at once. I stir this until the cheese has melted.

The thick, rich cheese sauce is what makes Creamy Potatoes Au Gratin so delicious!

I pour half the cheese sauce over the potatoes in the casserole dish then top the cheese with the remaining potato slices. The rest of the cheese sauce goes on top of the second layer of potatoes.

The casserole gets covered with foil and it goes into the oven for an hour and a half or until the potatoes are tender.

I melt the remaining 2 tablespoons of butter and combine them with a cup of Panko breadcrumbs making sure the breadcrumbs are well combined with the butter. The breadcrumbs get spread over the top of the casserole and I return it to the oven for 5 -10 minutes; until the breadcrumbs are toasty and golden.

To give the sauce a bit of time to set I allow the dish to rest for about 5 minutes. This is the part I have trouble with since I want to dive right into that cheesy, creamy deliciousness!

We love Creamy Potatoes Au Gratin with ham but it really works well with just about any meat!
