Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a wire rack for better air circulation.
Pat the chicken wings completely dry with paper towels to ensure the skin becomes crispy during roasting.
In a large bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, ensuring they do not touch.
Bake for 35 to 40 minutes, flipping the wings halfway through the cooking time, until the skin is golden brown.
While the wings bake, whisk together the sugar-free BBQ sauce, sriracha, and honey in a small mixing bowl.
Remove the wings from the oven and transfer them to a clean bowl, then toss with the spicy BBQ glaze until fully coated.
Return the glazed wings to the oven for an additional 3 to 5 minutes to allow the sauce to become tacky and caramelized.
Serve the hot wings immediately with fresh celery sticks on the side.
