First, preheat oven to 425ºF, and wash sweet potatoes.
Next, drizzle a 1/2 tablespoon of oil over each sweet potato. Make sure to coat the whole potato.
After you oil the potatoes, season with salt and pepper to taste.
Then, poke holes (with a fork or knife) all around the sweet potato, and wrap each potato in tin foil. Bake at 425ºF for 45-60 minutes, depending on the size of the sweet potatoes.
While the potatoes are cooking, choose which flavor variation(s) you would like, and prepare those ingredients. Set aside.
When the potatoes are done, make sure they are cooked all the way through by poking them with a fork. If there is no resistance, they are done.
Top with the flavor variation ingredients, and enjoy.
