Preheat your oven to 400°F (200°C).
Wash and scrub the russet potatoes thoroughly. Pat dry.
Prick each potato several times with a fork.
Rub each potato with olive oil and sprinkle with salt.
Bake the potatoes directly on the oven rack for about 45-60 minutes, or until fork-tender.
Let the potatoes cool slightly before slicing them in half lengthwise.
Scoop out the flesh from the inside of each half, leaving a thin layer of potato.
Brush the inside and outside of the potato skins with olive oil and season with salt and pepper.
Place the potato skins on a baking sheet and return them to the oven for about 10-15 minutes until crisp.
Remove from the oven, and fill each potato skin with shredded cheese, crumbled bacon, and green onions.
Return the loaded skins to the oven for an additional 5-10 minutes until the cheese is melted and bubbly.
Serve hot topped with a dollop of sour cream and extra green onions if desired.
