Preheat the air fryer to 360°F (180°C) for 5 minutes.
Brush or rub the frozen chicken breasts all over with the olive oil. Do not mix the oil and spices into a paste, as it will slide off the frozen meat.
Sprinkle the salt, pepper, garlic powder and paprika evenly over the oiled chicken.
Place the chicken in the preheated basket in a single layer, without touching. Cook at 360°F (180°C) for 10 minutes.
Flip the chicken with tongs and cook for another 10 to 15 minutes, depending on thickness.
Insert a meat thermometer into the thickest part of the breast. It must read at least 165°F (74°C). If not, cook 2 to 3 more minutes.
Rest the chicken on a cutting board for 5 minutes before slicing.
