01 - Preheat oven to 400°F. Rub potatoes with olive oil and sprinkle with salt. Prick each potato several times with a fork. Place directly on oven rack and bake for 50–60 minutes until skins are crisp and a knife slides easily into the center.
02 - While potatoes bake, combine shredded chicken, sour cream, milk, cheddar cheese, bacon, green onions, butter, garlic powder, smoked paprika, black pepper, and salt in a large bowl. Mix thoroughly until well incorporated.
03 - When cool enough to handle, cut potatoes in half lengthwise. Carefully scoop out flesh with a spoon, leaving 1/4-inch thick shells intact.
04 - Add scooped potato flesh to chicken mixture. Mash and mix until completely combined and creamy. Taste and adjust seasoning as needed.
05 - Spoon filling back into potato shells, mounding slightly. Top each with additional shredded cheddar cheese.
06 - Place stuffed potatoes on baking sheet and bake at 400°F for 15–20 minutes until cheese is melted and golden. Remove from oven, sprinkle with parsley, and serve hot.
