Creating BBQ Chicken Stuffed Potatoes is straightforward. Follow these steps to ensure your potatoes are perfectly cooked and filled:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).

2. Prepare the Potatoes: Scrub the russet potatoes thoroughly and dry them with a towel. Prick each potato several times with a fork to allow steam to escape while baking.

3. Season the Potatoes: Brush each potato lightly with olive oil. Sprinkle with salt and pepper to taste.

4. Bake the Potatoes: Place the prepared potatoes on a baking sheet and bake in the preheated oven for 45-55 minutes, or until they are tender when pierced with a fork.

5. Cook the Chicken: If you are not using pre-cooked chicken, cook the chicken breast in a skillet over medium heat until fully cooked. Shred the chicken using two forks.

6. Mix the Filling: In a mixing bowl, combine the shredded chicken with BBQ sauce. Stir until the chicken is well-coated.

7. Prepare to Stuff: Once the potatoes are baked and cool enough to handle, cut a slit down the center of each potato. Gently fluff the insides with a fork to create space for the filling.

8. Stuff the Potatoes: Spoon the BBQ chicken mixture into each potato, filling them generously.

9. Top with Cheese: Sprinkle the shredded cheese evenly over the tops of the stuffed potatoes.

10. Return to Oven: Place the stuffed potatoes back in the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.

11. Add Final Touches: Once out of the oven, add a dollop of sour cream and a sprinkle of chopped green onions to each potato for added flavor.
