Preheat your oven to 375°F (190°C).
Scrub the potatoes under running water and pat them completely dry.
Prick the potatoes 5-6 times all over with a fork. This allows steam to escape.
Rub each potato with olive oil and sprinkle generously with salt.
Place the potatoes directly on the middle oven rack and bake for 70-90 minutes, or until the skin is crispy and a fork pierces the center easily.
While the potatoes bake, prepare all your toppings and arrange them in separate bowls for serving.
Once the potatoes are cooked, carefully remove them from the oven.
Set up your "bar" with the hot potatoes and all the toppings.
Slice open the top of each potato lengthwise, fluff the inside with a fork, and let everyone build their masterpiece!
