Preheat your air fryer to 400°F (200°C).
Pat the chicken wings completely dry with paper towels to ensure the skin gets maximum crunch.
In a large bowl, toss the wings with olive oil, garlic powder, sea salt, and half of the black pepper until evenly coated.
Place the wings in the air fryer basket in a single layer, ensuring they are not crowded, and cook for 18-20 minutes, flipping halfway through.
While the wings are cooking, steam the broccoli florets in a steamer basket over boiling water for 5-7 minutes until they are bright green and tender.
In a small mixing bowl, whisk together the fresh lemon juice, lemon zest, and the remaining black pepper.
Transfer the hot, crispy wings to a clean bowl, pour the lemon-pepper mixture over them, and toss to coat thoroughly.
Plate the wings immediately alongside the steamed broccoli for a clean and satisfying meal.
