Sidle up to the table, split open a spud, and fill it with one of our four flavor combinations. Each topping combination is enough for four potatoes. If you've got a crowd to feed, bake more potatoes, and make more than one style of topping.
Preheat oven to 400 degrees. Prick potatoes all over with a fork, and rub them with oil. Place potatoes on a rimmed baking sheet; bake until easily pierced with the tip of a paring knife, 50 to 60 minutes.
Cut a deep cross in each potato; push ends together to open. Season with salt and pepper; add desired toppings.
