Wash and dry potatoes. Pierce each one with the tines of a fork several times.
Bake in a 375° oven for 60 minutes.
Remove from oven and allow potatoes to cool enough to handle.
Cut each potato in half.
Using a spoon, scoop out the flesh, leaving about a ¼ inch with the skin.
Brush the inside of each potato half with olive oil.
Season with salt and pepper.
Flip over shells and brush skin with olive oil.
Season with salt.
Bake in the oven for 10 minutes.
Flip shells over and bake for another 10 minutes.
Remove from oven and fill each shell with crumbled bacon and a generous mound of shredded cheeses.
Return to the oven and bake for 15-20 minutes or until cheese is melted and bubbly.
Serve topped with a dollop of sour cream and garnish with freshly chopped scallions or chives.
