Frequently Asked Questions About Potato au gratin
What is Potato au gratin?
Potato au gratin is a baked dish of thinly sliced potatoes layered with cream or milk and usually cheese. The top browns in the oven while the potatoes soften, making it a rich side dish often served with meat or vegetables.
What is the difference between Potato au gratin and scalloped potatoes?
Potato au gratin typically has cheese and a browned topping, while scalloped potatoes are often made with a creamy sauce without cheese. The names overlap in some recipes, so checking the ingredients is the clearest way to tell them apart.
How do you make Potato au gratin?
Slice peeled potatoes thinly and arrange them in a buttered baking dish with cream or milk, seasoning, and cheese. Bake until the potatoes are tender and the top is golden, then let the dish rest briefly so it holds together when served.
Which potatoes are best for Potato au gratin?
Starchy or all-purpose potatoes work well for Potato au gratin because they soften during baking and help thicken the creamy layers. Waxy potatoes hold their shape more firmly, so choose them if you prefer distinct slices rather than a softer, cohesive texture.
Why does the sauce split in Potato au gratin?
The sauce in Potato au gratin can split if it gets too hot or boils aggressively, especially when made with high-fat dairy. Bake it steadily rather than at excessive heat, and use full-fat cream or milk for a more stable, rich sauce.
Can Potato au gratin be made ahead?
Yes, you can assemble Potato au gratin ahead and refrigerate it before baking. Keep the potato slices covered with the cream mixture to limit browning, and bake it soon after preparation; a chilled dish may need extra time in the oven.
Can you freeze Potato au gratin?
Yes, Potato au gratin can be frozen, although the cream sauce may separate and the potatoes can become softer after thawing. Freeze it in airtight portions, thaw it in the refrigerator, and reheat it in the oven until hot throughout.
How long do leftovers of Potato au gratin keep?
Leftover Potato au gratin keeps in the refrigerator for about three to four days when cooled promptly and stored in a covered container. Discard it if it has been left at room temperature for too long, and reheat only the portion you plan to eat.
How do you reheat Potato au gratin without drying it out?
Reheat Potato au gratin in the oven with the dish covered to retain moisture. Remove the cover near the end if you want to crisp the top again. A microwave works for a quick serving, but it can make the layers softer.
What should you serve with Potato au gratin?
Serve Potato au gratin with a crisp green salad, roasted vegetables, or simply prepared meat or fish. Its creamy richness pairs especially well with bright, acidic sides such as a vinaigrette-dressed salad.

What is Potato au gratin?
Potato au gratin is a baked dish of thinly sliced potatoes layered with cream or a milk-based sauce, often with cheese, then cooked until tender beneath a browned top. It is associated with French cooking, though versions vary from kitchen to kitchen and may use different seasonings or amounts of cheese.
The contrast between its soft, creamy centre and golden crust makes it a comforting side for roast meat or poultry, or a substantial vegetarian centrepiece with salad. Potatoes provide most of its carbohydrates, while the creamy additions make it richer and more filling than plain baked potatoes. For a lighter version, use some milk in place of cream and serve it with a crisp, lightly dressed salad.
