Preheat your oven to 425°F and line a baking sheet with a wire cooling rack to allow for maximum air circulation.
Pat the chicken wings completely dry with paper towels to ensure the skin becomes extra crispy during roasting.
In a large mixing bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, smoked paprika, and cayenne pepper until evenly coated.
Arrange the wings in a single layer on the wire rack, making sure they do not touch each other.
Bake for 30 minutes, flipping the wings halfway through the cooking time, until they are golden brown and crisp.
In a small bowl, whisk together the sugar-free BBQ sauce and apple cider vinegar.
Remove the wings from the oven, place them in a clean bowl, and toss with the BBQ glaze until thoroughly coated.
Return the glazed wings to the rack and bake for an additional 5 minutes until the sauce is bubbly and tacky.
