Cooking Steps
Preheat oven to 425º.
On a baking sheet lined with aluminum foil, prick sweet potatoes all over with a fork. Rub the outsides with a small amount of olive oil if you intend to eat the skins.
Bake until tender, 45 to 50 minutes.
Let the potatoes cool, then cut the tops off with a knife and brush the tops with a dollop of butter.
Season with kosher salt and ground black pepper before serving.
