Ingredients
5 pounds sweet potatoes
Extra-virgin olive oil
4 tablespoons melted unsalted butter
1/4 teaspoon freshly grated nutmeg
Kosher salt and freshly ground pepper
Preparation
Using a fork, pierce sweet potatoes all over. Rub with oil; roast at 375 degrees until very soft, 1 to 1 1/2 hours. When they’re cool enough to handle, halve and scoop flesh into a bowl. Mash with butter, nutmeg, and salt and pepper.
