Do you like Potatoes au Gratin? Pretty fancy sounding French name for potatoes and cheese, right? My husband found a simple translation online for  “au gratin” which said that it simply means “cooked with a cover of cheese and bread crumbs mixed with butter”.

Well, I do not speak French, but I do know that I love this “comfort food” side dish! That description of au gratin fits this recipe perfectly! How can you go wrong with baked russet potatoes smothered in cheese sauce, and covered with a buttery bread crumb topping?

I found an old recipe recently that I had written down on an index card many years ago, made a few slight changes to the original, then made them for dinner. It is fairly straight forward to make, and was very delicious!

Here’s How To Make Au Gratin Potatoes:

Melt butter in a medium saucepan on medium low heat.  Stir in flour. Continue stirring; the mixture will clump up a bit (as seen in photo). Continue cooking for one minute, stirring often (this helps cook the “floury” taste out of it).

Cooking butter and flour to make a thickener for cheese sauce

Stir the milk, salt and pepper into butter mixture. Continue to cook on medium heat until mixture thickens considerably.  Add sharp cheddar cheese; stir until cheese has fully melted, and sauce is quite thick.

Peel, then slice potatoes into 1/8″ round slices.  If you have a mandoline, use that to get very thin slices (1/8″ is best!).  I have a mandoline, but used a knife to slice the potatoes to show how thin the potato slices should be (when using a knife try hard to get them 1/4″ or thinner), in case you don’t have one.

If the potatoes slices are too thick, it will take much longer to cook them until tender! The thinner the slices are, the better!

Spray a 2 quart sized baking dish with non-stick spray (bottom and sides).  Add the cheesy potatoes to the dish, and evenly spread to disperse. Set aside.

Create the buttery crumb topping by mixing together melted butter and soft breadcrumbs.

Bake potatoes in a preheated 400 degree oven for 60 minutes (covered with foil). Remove foil and continue baking for an additional 15 minutes, or until surface of potatoes is golden brown and cheese sauce is bubbly around the edges of dish.

When done baking, remove dish to a wire rack.  The cheese should be bubbling around the edges, and the potatoes should be fully cooked through and tender.

Season with additional salt and pepper, if desired, serve, and enjoy these au gratin potatoes!

We enjoyed the potatoes, served with grilled vegetables and my REALLY GOOD meatloaf. This meal was a tried and true meat and potatoes dinner, to be sure! Hope you will consider making this delicious side dish to compliment YOUR favorite meal!
