Take the chicken breasts out of the refrigerator 15 to 20 minutes before cooking.
Pat the chicken dry all over with paper towels, including the skin, underside, and edges around the bone.
Mix the salt, black pepper, paprika, olive oil, and dried oregano in a bowl.
Rub the mixture all over the chicken, including the skin, sides, and underside. If the skin lifts easily, rub a little of the mixture underneath, too, but do not pull the skin away from the meat.
Preheat the air fryer to 375°F / 190°C for 3 to 5 minutes.
Place the chicken breasts in the air fryer basket in a single layer, skin side down. Cook for 15 minutes.
Turn the chicken breasts over so the skin side faces up. Cook for another 10 to 15 minutes, or until the thickest part reaches 165°F / 74°C.
If the skin browns too quickly before the center is cooked, reduce the air fryer temperature to 350°F / 175°C and keep cooking until the chicken reaches 165°F / 74°C.
Transfer the chicken to a plate or board and let it rest for 5 to 10 minutes before slicing.
Serve whole, sliced, or remove the meat from the bone for meal prep.
