Crispy Cheesy Potato Skins

8 russet potatoes (about 5 lb.), washed
Olive oil for rubbing
1/2 cup butter, melted 
Sea salt and black pepper
8 oz shredded sharp Cheddar cheese
1 pound bacon, cooked, drained, chopped
1 bunch green onions, sliced
Sour cream 

1. Heat oven to 400°F. Poke potatoes all over with a sharp knife and rub with oil.
2. Place potatoes on a rimmed baking sheet and place in oven. Roast until soft, 60-75 minutes. Let cool.
3. Heat broiler to high. Cut potatoes in half and scoop out the flesh, leaving about a ¼ inch of potato. (Save the scooped out potato for another use.) Brush insides of potatoes with melted butter and season with salt and pepper; return to rack. Broil until crisp and flesh is golden, about 5-7 minutes.
4. Sprinkle cheese and bacon evenly among the potatoes. Place under the broiler until cheese is melted, about 2 minutes. Serve topped with sour cream, green onions, and black pepper.
