Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or place a wire rack over the sheet for better airflow.
Pat the chicken wings completely dry with paper towels; removing moisture is the secret to achieving a crispy skin without deep frying.
In a large mixing bowl, combine the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika, tossing until every wing is well-coated.
Spread the wings in a single layer on the baking sheet, ensuring they are not touching so they roast rather than steam.
Bake for 35 to 40 minutes, flipping the wings halfway through the cooking time, until they are golden brown and the skin is crackling.
In a small bowl, whisk together the sugar-free BBQ sauce and the hot sauce to create your spicy glaze.
Once the wings are finished, transfer them to a clean bowl and toss immediately with the spicy BBQ sauce until evenly glazed.
Serve the wings hot with fresh celery sticks on the side for a refreshing, crunchy contrast.
