Potatoes Au Gratin are one of my ultimate comfort foods! As soon as summer wanes, and the weather finally cools down, this is the recipe I want bubbling away in my oven. If you’re a regular reader of my blog, you know I love potatoes. Scalloped Potatoes and Potatoes Au Gratin are some of all-time of my favorite foods!

While these two yummy potato dishes have some similarities, the finished dishes are uniquely different.The difference between scalloped potatoes and Potatoes Au Gratin is that, firstly, scalloped potatoes are generally cut thicker than the potatoes used in au gratin. The second difference is that the Potatoes Au Gratin has Gruyere cheese added to them. This makes them even more ooey gooey delicious. The third difference is that they’re made with cream rather than whole milk. Lastly, they’re seasoned a bit differently. They have just a bit of grated nutmeg in them, which compliments and enhances the richness of the cream and Gruyere cheese.

Recipe Notes For Potatoes Au Gratin:

Mandoline: This recipe is a snap to make if you slice the potatoes with a mandoline or food processor. Both tools create thin, evenly sliced potatoes to help give this dish it’s signature texture.

Heat Up The Cream 1st: In this dish, it’s important to heat up the cream in a saucepan on the cooktop before it’s added to the potatoes. Please don’t skip this step!

Prep The Dish: Before you add the potatoes to the buttered baking dish, pour a thin layer of cream into the bottom of the baking dish, so the bottom layer of potatoes will cook well and soak up the delicious goodness of the rich cream, like all the other layers.

Mixing It Right: After warming the cream and adding the seasonings I mix the potatoes and cream together in a large bowl, mixing it all well with, with my well-washed hands, then separating the potato slices a bit with my fingers so they get coated more evenly with the cream mixture.

To Layer Or Not: Some other recipes for Potatoes Au Gratin suggest layering the potatoes, cheese and cream mixture, kind of like a lasagne. I think that process complicates this recipe unnecessarily. As long as you separate most of the potato slices, and get them coated with the cream mixture, there’s no need to layer the dish.

Yes Please With The Cheese: This recipe also calls for all the cheese to be placed on the top of the potatoes. This forms a perfectly delectable, lovely browned crust that is absolutely to-die-for! If the topping browns too quickly, loosely tent the top with aluminum foil.
