1Pat duck breasts dry with paper towels. Score skin in a crosshatch pattern without cutting into meat.
2Season with salt, pepper, and optionally five-spice powder or fresh herbs (rosemary and thyme).
3Preheat air fryer to 195°C (390°F). Place duck breasts skin-side up in basket.
4Cook for 5 minutes at 195°C, then reduce temperature to 160°C (320°F) and cook for another 10-12 minutes.
5If you see smoke during cooking, stop the air fryer, drain accumulated fat, and resume cooking.
6Check internal temperature: medium-rare 54°C (130°F), medium 60°C (140°F), well done 74°C (165°F).
7Remove duck breasts, loosely cover with foil, and let rest for 5-10 minutes.
8Serve with plum sauce, hoisin sauce, or cranberry sauce.
