Carefully score the top of each chicken breast in a shallow grid pattern using a sharp knife. This helps the delicious flavors really soak in!
In a small bowl, whisk together the paprika, garlic powder, onion powder, Italian seasoning, cayenne pepper (if you're using it), and a generous pinch of salt and pepper.
Generously rub this vibrant seasoning mix all over both sides of the scored chicken breasts, ensuring they are well coated.
Place the seasoned chicken in your air fryer basket, making sure not to overcrowd it (cook in batches if necessary). Cook at 400°F (200°C) for 14-16 minutes, flipping halfway through, or until the chicken reaches an internal temperature of 165°F (74°C). Cooking time may vary based on the thickness of your chicken.
While the chicken is cooking, prepare your luscious garlic butter sauce: In another small bowl, stir together the melted butter, minced fresh garlic, and sugar-free honey substitute until well combined.
Once the initial cooking time is almost up (around the 14-minute mark), open the air fryer and generously brush the garlic butter mixture over the chicken breasts.
Return the chicken to the air fryer and cook for an additional 2 minutes, allowing the garlic butter to caramelize slightly and fully infuse the chicken.
For an extra burst of flavor and moisture, give the chicken one more brush with any remaining garlic butter just before serving. Enjoy your incredibly tender and flavorful chicken!
