Pat the chicken breasts dry with paper towels until they feel slightly tacky, which helps the seasoning adhere and promotes a crisp exterior.
In a small mixing bowl, combine olive oil, paprika, garlic powder, dried thyme, salt, and pepper. Mix well until the spices are evenly distributed.
Rub the seasoning mixture all over each chicken breast, ensuring an even coat on all sides.
Preheat your air fryer to 200°C (390°F) for about 3 minutes. This step helps achieve an even, crispy exterior.
Place the seasoned chicken breasts in a single layer in the air fryer basket, making sure they aren’t overlapping or crowded, so the hot air circulates freely.
Cook for 10-12 minutes, flipping the chicken halfway through. You’ll hear a gentle sizzling, and the chicken will develop a golden, slightly crispy surface.
Insert a meat thermometer into the thickest part of the chicken; once it reads 75°C (165°F), remove the chicken from the air fryer.
Let the chicken rest for 5 minutes on a plate, allowing the juices to redistribute, which keeps the meat moist and tender.
Optionally, squeeze fresh lemon juice over the chicken for a bright, zesty finish before slicing.
Slice the chicken breasts against the grain and serve immediately, enjoying the juicy interior and crisp exterior.
