Preheat your air fryer to 200°C (390°F).
Pat the chicken breasts dry thoroughly with paper towels, removing excess moisture for better seasoning adhesion and crispiness.
In a mixing bowl, combine paprika, garlic powder, salt, cayenne pepper, black pepper, lemon zest, and olive oil, stirring until well mixed to create a flavorful rub.
Rub the spice mixture all over the chicken breasts, coating them evenly on all sides. This will help develop a flavorful crust.
Place the seasoned chicken breasts in the air fryer basket, skin side down if using skin, ensuring they aren’t overlapping for even cooking.
Cook for about 10 minutes, then flip the chicken breasts using tongs, and cook for another 8-10 minutes until golden and firm.
Use a meat thermometer to check the internal temperature, which should reach 74°C (165°F). The chicken should feel firm but not hard.
Remove the chicken from the air fryer and let it rest for 5 minutes to allow juices to redistribute, ensuring maximum juiciness.
Slice the chicken against the grain, revealing a juicy interior with a crispy, flavorful exterior.
Serve immediately, enjoying the crispy outside and tender, moist inside with your favorite sides.
