01 - Preheat oven to 400°F. Rub each potato thoroughly with olive oil and sprinkle evenly with kosher salt. Pierce potatoes several times with a fork to allow steam to escape during baking.
02 - Place potatoes directly on center oven rack. Bake for 50 to 60 minutes until skins are crisp and fork-tender. Remove from oven and let cool until safe to handle.
03 - While potatoes bake, combine shredded chicken, sour cream, milk, 1/4 cup cheddar cheese, bacon, green onions, butter, garlic powder, smoked paprika, black pepper, and salt in large bowl. Mix thoroughly until fully incorporated.
04 - Cut cooled potatoes in half lengthwise. Using a spoon, carefully scoop out flesh leaving approximately 1/4-inch thick shells intact. Set shells aside on baking sheet.
05 - Add scooped potato flesh to chicken mixture. Mash with potato masher until smooth and creamy throughout. Taste and adjust seasoning if necessary.
06 - Spoon filling mixture back into potato shells, mounding slightly above edges. Top each stuffed potato evenly with remaining 1/4 cup cheddar cheese.
07 - Return baking sheet to 400°F oven. Bake for 15 to 20 minutes until cheese is fully melted and golden brown on top.
08 - Remove from oven. Sprinkle generously with fresh chopped parsley and serve immediately while hot.
