Preheat your oven to 400°F and line a large baking sheet with parchment paper, placing a wire rack on top for maximum airflow.
Pat the chicken wings extremely dry with paper towels to ensure the skin becomes golden and crispy during the roasting process.
In a large bowl, whisk together the avocado oil, smoked paprika, garlic powder, onion powder, cayenne pepper, sea salt, and black pepper.
Add the wings to the bowl and toss thoroughly until every wing is evenly coated in the aromatic spice blend.
Arrange the wings in a single layer on the wire rack and bake for 35-40 minutes, flipping halfway through, until they reach a deep mahogany color.
Transfer the hot wings to a clean bowl, pour over the sugar-free BBQ sauce, and toss gently to coat each piece in the sticky glaze.
Slice the celery and carrot into thin sticks and serve alongside the wings for a refreshing, fiber-rich crunch.
