Preheat your air fryer to 200°C (390°F) to ensure it's hot and ready for cooking.
Pat the chicken breasts dry with paper towels; this step helps achieve a crispy exterior.
Rub each chicken breast with olive oil, coating evenly to promote crispness.
Sprinkle salt, pepper, paprika, and lemon zest all over the chicken, massaging the seasonings into the meat for full flavor coverage.
Place the seasoned chicken breasts into the air fryer basket in a single layer, ensuring space between each piece for air circulation.
Insert the basket into the air fryer and cook for 10-12 minutes, flipping the chicken halfway through with tongs to promote even browning.
Use a meat thermometer to check that the internal temperature reaches 75°C (165°F), ensuring the chicken is fully cooked and safe to eat.
Once cooked, remove the chicken from the air fryer and let it rest for 5 minutes to retain juices.
Slice the chicken breasts and serve immediately, enjoying the crispy exterior and juicy interior that make this dish so satisfying.
