Start by patting the chicken wings dry with paper towels. This step is crucial for achieving a crispy texture. After drying, season the wings with kosher salt and ground black pepper.
Preheat your air fryer to 400°F (200°C). Lightly spray the air fryer basket with avocado oil to prevent sticking. Arrange the seasoned wings in a single layer in the basket, ensuring they aren't overcrowded. Air fry for about 20 minutes, flipping the wings halfway through to ensure even cooking
While the wings are cooking, melt the salted butter in a small saucepan over medium heat. Add the finely minced garlic to the melted butter and sauté for about 1 minute, or until fragrant. Remove from heat and set aside.
Once the wings are cooked and crispy, transfer them to a mixing bowl. Pour the garlic butter sauce over the wings and toss them gently to coat evenly.
Sprinkle the freshly grated parmesan cheese and chopped flat-leaf parsley over the wings. Toss again to ensure the cheese melts and adheres to the wings. Serve immediately for the best flavor and texture.
