01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Scrub the potatoes thoroughly and pat dry. Pierce each potato several times with a fork.
03 - Rub potatoes with 1 tablespoon olive oil and sprinkle with ¼ teaspoon salt. Place directly on the oven rack. Bake for 40–45 minutes, or until potatoes are tender and skins are crisp.
04 - Meanwhile, cook the beef bacon in a skillet over medium heat until crispy, about 6–8 minutes. Transfer to a paper towel-lined plate.
05 - Remove the potatoes from the oven. Let cool slightly for about 10 minutes until safe to handle.
06 - Slice each potato in half lengthwise. Using a spoon, carefully scoop out most of the flesh, leaving a ¼-inch border.
07 - Brush the inside and outside of each skin with the remaining olive oil. Season with pepper and a pinch of salt. Place skins cut side up on the baking sheet.
08 - Return to the oven and bake for 7–10 minutes until the edges are golden brown.
09 - Sprinkle cheddar cheese evenly inside each skin. Top with crispy beef bacon.
10 - Return to the oven for 3–4 minutes until the cheese is melted and bubbly.
11 - Remove from oven. Top each potato skin with a dollop of sour cream, sliced scallions, and chives if desired. Serve warm.
