Make a slit in the top of each sweet potato. Top with 1 tablespoon of butter and season with the salt and pepper.
Prick your sweet potatoes each 2-3 time with a fork, then place them directly on the oven rack in the middle of the oven, above the rack with the foil. Turn the oven on to 425. Bake for 45 minutes for sweet potatoes/yams that are 2-3 inches in diameter. For sweet potatoes that are up to 4 inches in diameter, bake for an hour. For super large sweet potatoes, bake for an hour and 15 minutes. After the time has elapsed, don't open the oven but turn it off. Let the sweet potatoes sit in the oven for at least 30 minutes but up to an hour.
