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