We love that this recipe replaces two-thirds of the butter with heart-healthy olive oil. We’d go a step further and swap out all or half of the cream for plain yogurt to further cut the fat and calorie count. – Editor

Cook: 1 hr 30 min

Yield: 4 servings

Level: Intermediate


2 tablespoons olive oil

1 tablespoon unsalted butter

3 Vidalia (or other sweet variety) onion, peeled, halved and thinly sliced on a mandoline

Salt and freshly ground black pepper

3 tablespoons finely chopped fresh sage leaves

6 large Idaho potatoes, peeled and sliced thinly on a mandoline

2 cups heavy cream [or replace the heavy cream with Whole Milk Plain Yogurt – Editor]


Preheat oven to 375 degrees F.

Heat oil and butter in a large saute pan over medium-high heat. Add the onions, season with salt and pepper and cook until caramelized, about 15 to 20 minutes. Remove from the heat and stir in the sage. Let cool slightly.

Make a layer of potato slices in a 10 by 10 by 2-inch casserole, season to taste with salt and pepper, spread 1/12 of the onion mixture over the potatoes and coat with 2 tablespoons of the cream.

Repeat each step to yield 12 layers. Press down gently on the layers, place the dish on a sheet pan and bake, covered for 25 minutes.

Remove cover and bake for another 20 to 25 minutes, or until the potatoes are tender and golden brown on top. Let rest 10 minutes before serving. Original recipe appears at Food Network.
