01 - Preheat oven to 400°F. Rub potatoes with olive oil and sprinkle with salt. Prick each potato several times with a fork.
02 - Place potatoes directly on oven rack and bake for 50-60 minutes until skins are crisp and a knife slides easily into the center. Let cool slightly.
03 - In a large bowl, combine shredded chicken, sour cream, milk, cheddar cheese, bacon (if using), green onions, butter, garlic powder, smoked paprika, black pepper, and salt. Mix well.
04 - Cut each cooled potato in half lengthwise. Using a spoon, carefully scoop out most of the flesh, leaving a 1/4-inch shell.
05 - Add scooped potato flesh to chicken filling mixture. Mash and mix until well combined and creamy. Adjust seasoning if needed.
06 - Spoon filling back into potato shells, mounding slightly. Top each with additional shredded cheddar cheese.
07 - Return stuffed potatoes to baking sheet and bake at 400°F for 15-20 minutes until cheese is melted and golden.
08 - Remove from oven, sprinkle with chopped parsley, and serve hot.
