Preheat your oven to 400°F and line a baking sheet with a wire cooling rack to allow air to circulate around the wings.
Pat the chicken wings thoroughly dry with paper towels; removing moisture is the secret to achieving a crispy skin without deep frying.
In a large mixing bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Place the wings on the wire rack in a single layer, ensuring they are not touching each other.
Bake for 35 to 40 minutes, flipping the wings halfway through, until the skin is golden brown and crispy.
While the wings bake, whisk together the sugar-free BBQ sauce and hot sauce in a clean bowl.
Remove the wings from the oven and immediately toss them in the spicy BBQ sauce until every wing is well-glazed.
Serve the wings hot alongside the fresh celery sticks for a cooling crunch.
