Preheat your oven to 400°F.
Wash and scrub the potatoes thoroughly, then dry them with a towel.
Pierce each potato several times with a fork, then rub them with olive oil and sprinkle with salt.
Place the potatoes directly on the oven rack and bake for 45-60 minutes, or until they are tender when pierced with a fork.
Once baked, remove the potatoes from the oven and let them cool for about 10 minutes.
Cut each potato in half lengthwise and scoop out some of the flesh, leaving about 1/4 inch of potato on the skin.
Brush the insides of the potato skins with olive oil and season with black pepper and garlic powder.
Place the skins back on a baking sheet and sprinkle with cheddar cheese and crumbled bacon.
Return the loaded skins to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Remove from the oven and top with sour cream and chopped green onions before serving.
