Preheat your oven to 350°F (175°C).
Scrub the potatoes thoroughly, rinse, and pat dry.
Pierce each potato several times with a fork.
Place the potatoes on a baking sheet.
Lightly drizzle with olive oil.
Sprinkle generously with kosher salt.
Bake for about 65–75 minutes, or until fork-tender with crispy skins.
While the potatoes bake, combine the chopped chicken and barbecue sauce in a medium saucepan.
Warm over low heat for about 8–10 minutes, stirring occasionally until heated through.
Add additional barbecue sauce if you prefer a saucier filling.
Remove the baked potatoes from the oven.
Slice each potato down the center and fluff the inside with a fork.
Spoon the hot BBQ Chicken Stuffed Baked Potatoes filling generously into each potato.
Top with shredded cheese, sour cream, and chopped chives if desired.
Serve immediately while hot.
