Prep Time: 15 Muns
Cook Time: 50 mins
Total: 65 Minutes
Servings: 4


1 1/2 pounds Yukon Gold potatoes, peeled, cut into 1/4 inch thick slices
1 large yellow onion, thinly sliced
2 tablespoons unsalted butter
2 teaspoons Herbes de Provence, or dried thyme
1/2 teaspoon white pepper
1/2 teaspoon nutmeg
1 cup (packed) grated Gruyere cheese (about 4 oz)
8 tablespoons (packed) freshly grated Parmesan cheese (about 2 oz)
2/3 cup half-and-half (half cream, half milk)


-Preheat oven to 400°F

-Boil the potatoes:
Boil the potatoes for 4 minutes in salted water (1 tablespoon of salt for 2 quarts of water). Drain and set aside.

-Sauté the onions, sprinkle with salt and herbs:
Heat the butter over medium-high heat in a large sauté pan and cook the onions, stirring occasionally, until they are softened, about 5 minutes.

-Sprinkle them with salt and the Herbes de Provence. Turn off the heat and set aside.

-Layer potatoes, cheeses, onions, nutmeg in baking dish, pour over with half and half:
Spread half of the sliced potatoes over the bottom of an 11x7-inch baking dish (Pyrex works well). Sprinkle well with salt and white pepper.

-Sprinkle with about a third of the Gruyere and Parmesan cheeses. Top with the onions, the nutmeg and another 1/3 of the cheeses.

-Layer the remaining sliced potatoes on top of the cheeses.

-Pour the half and half over everything. Sprinkle again with salt and pepper.

Sprinkle the remaining one-third of the cheeses over everything. (At this point you can make a day ahead, just cover and refrigerate until time to cook.)

Bake uncovered in 400°F oven until cream thickens and everything is nicely browned, about 25-30 minutes.
