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 knife slides easily into center. Remove and let cool until safe to handle.
03 - In 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 thoroughly until well incorporated.
04 - Cut cooled potatoes in half lengthwise. Using spoon, carefully scoop out flesh leaving 1/4-inch thick shell intact. Reserve scooped potato flesh.
05 - Add scooped potato flesh to chicken mixture. Mash and stir until completely blended and creamy. Taste and adjust seasoning as needed.
06 - Spoon filling mixture back into potato shells, mounding slightly above edges. Top each stuffed half 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 generously with chopped fresh parsley, and serve immediately while hot.
