01 - Preheat oven to 400°F. Pierce sweet potatoes several times with a fork. Arrange on a baking sheet and roast for 45–50 minutes until completely tender when pierced with a fork.
02 - While potatoes roast, combine shredded chicken and barbecue sauce in a saucepan over low heat. Stir continuously until warmed through and evenly coated.
03 - Remove roasted potatoes from oven and allow to cool for 2–3 minutes. Slice each potato lengthwise and gently fluff the interior flesh with a fork, creating space for the filling.
04 - Divide BBQ chicken mixture evenly among the sweet potatoes. Top each with a generous portion of shredded cheddar cheese. Return to oven for approximately 5 minutes or until cheese is fully melted and bubbly.
05 - Remove from oven. Garnish with sliced green onions, diced red onion, a dollop of sour cream, and fresh herbs. Serve immediately while hot.
