01 - Preheat oven to 400°F (204°C). Prick potatoes with a fork and bake directly on the oven rack until tender, approximately 50 minutes.
02 - Remove baked potatoes from oven and allow to cool until safe to handle. Slice each potato in half lengthwise. Using a spoon, carefully scoop out most of the flesh, leaving a 1/4-inch border to maintain structure.
03 - Brush the hollowed potato skins with melted butter, season with salt and pepper. Arrange skins cut-side up on a baking tray. Bake for 10 minutes at 400°F (204°C) until lightly crisped.
04 - Sprinkle each skin with cheddar cheese and chopped bacon. Return tray to oven and bake for 5–6 minutes, until the cheese is bubbly and melted.
05 - Transfer skins to a platter. Top with sour cream and garnish with fresh chives before serving.
