Preheat the oven to 400°F (200°C).
Wash and dry the russet potatoes thoroughly, then poke holes in each one with a fork.
Rub the potatoes with olive oil and season generously with salt and pepper.
Place the potatoes directly on the oven rack and bake for 45 minutes to 1 hour, until tender.
Remove the potatoes from the oven and let them cool for about 10 minutes.
Cut each potato in half lengthwise and scoop out a small portion of the flesh, leaving about 1/4 inch of potato on the skin.
Brush the insides of the potato skins with more olive oil and sprinkle again with salt and pepper.
Return the potato skins to the oven for an additional 10-15 minutes, until crispy.
Fill each potato skin with cheddar cheese, bacon, and green onions, then return them to the oven for 5-7 minutes until the cheese is melted.
Remove from the oven and let cool for a few minutes before adding a dollop of sour cream on top and serving.
