I like to make this au gratin potatoes recipe any time of the year, but especially for holiday meals. This prepared potato gratin is layered with potato rounds, a sprinkle of garlic cloves, grated cheeses and a mix of cream and milk. The result is a rich flavor, the best texture and the very definition of comfort food.

This potato dish bakes up in about an hour and is absolute cheesy goodness. I serve this dish for Christmas dinner with a Honeybaked Ham or at Easter with lamb. You just can’t go wrong because everyone loves potatoes! The full instructions are on the recipe card below.

What goes well with au gratin potatoes with Gruyere?

This crowd pleaser is an easy and simple holiday dinner side dish. It’s also great for weeknight dinners alongside a pork tenderloin or steak off the grill, and the leftovers are just as delicious.

Can you reheat potatoes au gratin?

This dish is easy to reheat on the stove, in the oven or in the microwave. I will heat this slowly in the oven covered with foil as to not burn the already melted cheese on top. The microwave is easy for reheating single portions. About a minute will do.

What’s the difference between scalloped potatoes and potatoes au gratin?

The key ingredient that differentiates these two types of potato dishes is cheese. Scalloped potatoes consist of thin slices of potatoes baked with cream or milk while potatoes au gratin are layered with the best cheese. 

How to make this au gratin recipe with Gruyere

I prefer to use Yukon Gold potatoes sliced into thin discs that I have been pre-boiled for about 10 minutes. These are the best potatoes to use because they are buttery to begin with so this flavor is accentuated in this dish.

The mixture of cheddar and Gruyere cheeses melt beautifully together and complement these golden potatoes without being overpowering.

Milk or cream?

I like to use a combination of both. The cream adds richness to the dish while the milk balances the texture of the sauce. Just be sure to heat up the milk and cream in a small bowl ahead of time since you are using it on hot layers of potatoes.

Can I make these potatoes the night before?

The scalloped potatoes can be prepared ahead of time and stored in the fridge until ready to bake. 

Allow the dish to come to room temperature before putting the baking dish in the oven.
