Start by placing the chicken breasts in a bowl or zip-close bag. Ensure they are all together to absorb the flavors properly.
Pour in the olive oil and toss the chicken to coat it completely. The chicken should feel slick and shiny for the seasoning to stick well.
Sprinkle on the lemon pepper seasoning, garlic powder, and onion powder. Ensure the chicken is evenly coated to avoid bland bites.
Allow the seasoned chicken to marinate for at least 15 minutes. This enhances the flavor, but do not leave it too long to avoid excessive saltiness.
While the chicken is marinating, preheat your air fryer to 390 degrees F (199 degrees C). A hot air fryer locks in moisture and helps achieve a crispy exterior.
Carefully place the chicken in a single layer in the air fryer basket, ensuring space around each piece for even cooking. Overcrowding may cause the chicken to become rubbery.
Air fry for about 20 minutes, checking for a golden brown color and ensuring it reaches an internal temperature of 165 degrees F (74 degrees C). Monitor closely to prevent overcooking, which can dry out the chicken.
Once cooked, let the chicken rest for a few minutes before slicing. This allows the juices to redistribute for a more tender bite.
