Potato gratin is one of those dishes that is simple to make, but the results are fantastic and so rewarding. A perfect gratin has a crispy top but is thick, rich, and creamy. The potatoes are soft but still intact, and the whole dish has a decadent cheesy flavor.

This recipe is loosely based on Orlando Murrin's recipe in "A Table in the Tarn: Living, Eating, and Cooking in Rural France." It's a classic French recipe with thinly sliced potatoes and garlic-infused cream, along with gooey Gruyère and brie cheeses. The best potatoes for a gratin are floury types such as King Edward or Maris Piper, which are more widely available in places such as the U.K., Ireland, and Canada, but you can use any potato that's recommended for mashing. Russet potatoes will work in this recipe.
Some potato gratin recipes call for soaking potatoes prior to assembling the gratin, but that's not necessary here. Instead, the recipe comes together in a straightforward manner, with the thin slices simmering in milk and cream until it thickens a bit. Serve the gratin with beef such as London broil or even a simply roasted chicken for a classic meal.
"This recipe is the epitome of potato gratin from scratch. While it does take time to prep the potatoes and other ingredients, it was taxing, but worth the effort. While the recommended cheeses are a bit pricier than some other options, the combination of Gruyère and brie makes this dish great." —Colleen Graham
2 pounds (1 kilogram) potatoes, such as King Edward, Maris Piper, or Idaho russets
1 cup (235 milliliters) whole milk
1 cup (235 milliliters) heavy whipping cream
2 cloves garlic, lightly crushed, divided
Kosher salt, to taste
1 dash freshly ground pepper, plus more for seasoning
1 dash freshly grated nutmeg
1/2 cup (125 grams) grated Gruyère cheese
2 tablespoons plus 1 teaspoon unsalted butter, divided
1/2 cup (125 grams) brie
Steps to Make It
Gather the ingredients. Preheat the oven to 350 F (175 C/Gas Mark 4).
Peel, rinse, and dry the potatoes and slice as thinly as possible (a mandoline is good for this, but a sharp knife works too).
In a large saucepan, place the potatoes, milk, cream, 1 of the crushed garlic cloves, salt to taste, a dash of pepper, and a dash of nutmeg or mace.
Bring to a very gentle boil over medium-low heat and simmer for 10 minutes until the cream thickens.
Remove from the heat and add the grated Gruyère. Stir until the cheese has melted.
Generously grease a 1 1/2 to 2-quart baking dish with 1 teaspoon of the butter, then rub the dish all over with the remaining lightly crushed clove of garlic.
Pour the potato mixture into the dish, using a spoon to gently move the potatoes in the cream mixture to make sure they are all covered.
Finely slice the brie into long strips and lay across the top of the gratin. Dot the surface with the remaining 2 tablespoons butter. Season with salt and pepper.
Bake for about 40 minutes or until the top is bubbly and golden brown and the potatoes are soft when pierced with a knife. If the top is browning too quickly before the potatoes are cooked, cover with aluminum foil. Serve immediately. Enjoy.
- Another way to serve the gratin is to allow it to go cold and then cut it into rounds. Place the rounds on a greased baking sheet and reheat in a 350 F oven for approximately 10 minutes.
- You can slice the potatoes ahead of time to help prep the dish. Simply keep them in a bowl full of ice-cold water in the fridge and then pat them dry before using them in the recipe. They'll be fine up to 24 hours ahead of time.
- The gratin can be made ahead of time. Cool it to room temperature and refrigerate for up to two days. To reheat, remove from the fridge to room temperature for 30 minutes while the oven heats to 350 F, to prevent a cold dish from cracking in a hot oven. Once the oven is heated, cover the gratin with aluminum foil and reheat for about 20 minutes or until warm and bubbly.
- Try this dish with a dash of mace rather than nutmeg.
- Switch from Gruyère to aged cheddar cheese.
How to Store and Freeze Potato Gratin
- Leftovers should keep for three to four days. Remove from the fridge, let it come to room temperature, and then reheat in a 350 F oven.
- You can also freeze potato gratin. Wrap the dish tightly in foil and freeze for up to six months. Remove and bake from frozen at 350 F until heated through, about 30 minutes.
What Does "Gratin" Mean?
Often called "au gratin," this is a French term that refers to a dish topped with butter and either cheese or breadcrumbs, or both. When either baked or broiled, the top becomes brown and crispy. While potatoes are the most common base for gratin dishes, other vegetables and even seafood are found in gratin recipes as well.
What's the Difference Between Potato Gratin and Scalloped Potatoes?
Both of these consist of thinly sliced starchy potatoes layered in a casserole dish with cream and then baked in the oven. A gratin, however, contains cheese and scalloped potatoes typically do not.
