Preheat your oven to 400°F (200°C) and line a large baking sheet with a wire cooling rack to allow for maximum air circulation.
Pat the chicken wings completely dry with paper towels, as removing moisture is the secret to achieving a truly crispy skin.
In a large mixing bowl, toss the wings with the avocado oil, cracked black pepper, sea salt, garlic powder, and onion powder until every piece is evenly coated.
Arrange the wings in a single layer on the wire rack, ensuring they are not touching each other to prevent steaming.
Bake for 35 to 40 minutes, flipping the wings halfway through the cooking time, until they are deeply golden brown and the skin is crackling.
While the wings are still piping hot, transfer them to a clean bowl and toss with the fresh lemon zest and lemon juice until well coated.
Garnish the wings with finely chopped fresh parsley and serve immediately while they are at their peak crispiness.
