01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Pierce the potatoes several times with a fork. Bake directly on the oven rack for 40–50 minutes, or until tender.
03 - Let potatoes cool slightly, then cut each in half lengthwise. Carefully scoop out most of the flesh, leaving a 1/4-inch shell (reserve the scooped potato for another use).
04 - Increase oven heat to 425°F. Brush both sides of potato skins with olive oil and season with salt and pepper. Place skins cut side down on the baking sheet and bake for 10 minutes.
05 - Flip skins cut side up, sprinkle evenly with cheddar cheese and crumbled bacon. Return to oven for 5–7 minutes, until cheese is melted and bubbly.
06 - Remove from oven. Top each potato skin with a dollop of sour cream, green onions, and chives. Serve immediately.
