01 - Preheat oven to 400°F. Rub potatoes thoroughly with olive oil and sprinkle with kosher salt. Prick each potato several times with a fork to allow steam to escape during baking.
02 - Place potatoes directly on oven rack and bake for 50–60 minutes until skins are crisp and a knife slides easily into the centers. Remove and let cool until safe to handle.
03 - 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 uniform.
04 - Cut cooled potatoes in half lengthwise. Carefully scoop out flesh with a spoon, leaving approximately 1/4-inch thick shells intact.
05 - Add scooped potato flesh to the chicken mixture. Mash and stir until completely incorporated and smooth throughout. Adjust seasoning to taste if necessary.
06 - Spoon filling generously back into potato shells, creating a slight mound on top of each. Sprinkle additional shredded cheddar cheese evenly over filling.
07 - Transfer stuffed potatoes to a baking sheet. Bake at 400°F for 15–20 minutes until cheese is fully melted and lightly golden on top.
08 - Remove from oven and sprinkle with chopped fresh parsley. Serve immediately while hot.
