01 - Preheat oven to 400°F. Rub potatoes with olive oil, sprinkle with salt, and prick several times with a fork. Place directly on oven rack and bake for 50-60 minutes until skins are crisp and tender throughout.
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 - Once potatoes are cool enough to handle, cut each in half lengthwise. Carefully scoop out most of the flesh with a spoon, leaving about 1/4-inch thick shells intact.
04 - Add scooped potato flesh to the chicken filling mixture. Mash and mix until completely combined and creamy. Taste and adjust seasoning if necessary.
05 - Spoon filling back into potato shells, mounding slightly above edges. Top each stuffed potato with additional shredded cheddar cheese.
06 - Return stuffed potatoes to a baking sheet and bake at 400°F for 15-20 minutes until cheese is melted and golden brown. Remove from oven, garnish with fresh parsley, and serve immediately.
