01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Pierce potatoes several times with a fork. Place directly on the oven rack and bake for 40 to 45 minutes until skins are crisp and potatoes are tender.
03 - While potatoes bake, cook bacon in a skillet over medium heat until crispy. Drain on paper towels and crumble once cooled.
04 - Remove potatoes from oven and allow to cool slightly. Slice each in half lengthwise. Carefully scoop out most of the flesh, leaving about ¼ inch attached to skin.
05 - Brush both sides of potato skins with olive oil and season with salt and black pepper. Place skin-side down on baking sheet.
06 - Return skins to oven and bake for 10 minutes, flipping halfway through, until edges are golden and crisp.
07 - Fill each skin with shredded cheddar and crumbled bacon. Bake for an additional 3 to 4 minutes until cheese is melted and bubbly.
08 - Top filled potato skins with sliced green onions and a dollop of sour cream if desired. Serve immediately.
