01 - Set the oven to 425°F and line a baking sheet with aluminum foil.
02 - Prick each potato several times with a fork. Rub them evenly with olive oil and sprinkle with kosher salt.
03 - Arrange the potatoes on the prepared sheet and bake for 50 to 60 minutes, until the skin is crisp and a fork pierces easily.
04 - Remove from oven and allow to cool slightly. Slice each potato lengthwise and gently squeeze ends to open. Fluff the interior with a fork.
05 - Place a small pat of unsalted butter inside each potato.
06 - Sprinkle shredded cheddar over each potato and return to the oven for 3 to 5 minutes until melted.
07 - Top with crumbled bacon, a dollop of sour cream, chopped chives, and freshly ground black pepper. Serve immediately.
