01 - Preheat oven to 400°F. Rub potatoes with olive oil and sprinkle with 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 center. Allow to cool slightly for safe handling.
03 - While potatoes bake, combine shredded chicken, sour cream, milk, cheddar cheese, bacon (if using), green onions, butter, garlic powder, smoked paprika, black pepper, and salt in a large bowl. Mix thoroughly until all ingredients are well incorporated.
04 - Cut cooled potatoes in half lengthwise. Using a spoon, carefully scoop out most of the flesh while leaving a 1/4-inch shell intact to maintain structural integrity.
05 - Add scooped potato flesh to the chicken filling mixture. Mash and mix until completely combined and creamy. Taste and adjust seasoning if necessary.
06 - Spoon filling back into potato shells, creating a slight mound on each. Top each stuffed potato evenly 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 brown.
08 - Remove from oven, sprinkle with chopped fresh parsley, and serve immediately while hot.
