This is my absolute favorite way to eat sweet potato!
Preheat oven to 425° F.
Peel potatoes and cut into uniform size chunks.
Melt the butter, pour a thin layer of butter into a large baking dish and spread the potatoes out in the dish. Then brush the potatoes with butter so that they are coated.
Sprinkle with salt.
Roast potatoes for 30-45 minutes.
