Ingredients

4 pounds Yukon Gold potatoes, peeled and cut into 1 1/2-inch chunks 

Kosher salt and freshly ground pepper 

6 tablespoons rendered duck fat or extra-virgin olive oil 

3 dried bay leaves 

2 sprigs rosemary 

Preparation

Preheat oven to 450 degrees. In a large pot, cover potatoes with 2 inches of water and bring to a boil. Season generously with salt and cook until potatoes are just tender, about 5 minutes. Drain and toss several times in a colander. (Potatoes should break apart slightly.)

Add duck fat and herbs to roasting pan or a rimmed baking sheet; heat in oven until herbs are sizzling slightly, about 5 minutes. Add potatoes and toss with a spoon until evenly coated. Roast, flipping once, until golden and crisp, about 35 minutes. Season with salt and pepper; serve immediately.
