Ingredients

2 large sweet potatoes, 2 pounds, cut into 3/4-inch dice

6 tablespoons olive oil

1 medium onion, peeled and cut into 1/3-inch dice

2 tablespoons roughly chopped fresh flat-leaf parsley

Coarse salt and freshly ground pepper

Preparation

Bring a medium pot of salted water to a boil. Add sweet potatoes, and cook until they can be easily pierced with a fork but still offer some resistance, 3 to 4 minutes. Drain, and rinse under cold running water. Refrigerate until completely chilled, about 1 hour.

Heat 2 tablespoons olive oil in a large skillet over medium heat. Add onions, and saute, stirring occasionally, until onions are tender and golden brown, about 20 minutes. Transfer onions to a small bowl, and set aside.

Pour remaining 4 tablespoons olive oil into the skillet, and place over medium-high heat. Add potatoes, and cook, stirring occasionally, until golden brown, about 8 minutes. Add reserved onions, and cook 2 minutes. Toss in parsley, and adjust the seasoning to taste with salt and pepper. Serve immediately.
