Begin by setting your air fryer to 400°F (200°C) and allowing it to preheat.
Dry the chicken breasts thoroughly then place them in a bowl; coat evenly with olive oil.
Combine smoked paprika, cumin, onion powder, salt, and pepper in a small bowl and evenly press the spice mix onto both sides of the chicken breasts.
Arrange the seasoned chicken breasts in your air fryer basket in a single layer and cook for 4 minutes.
Flip the chicken over carefully and air fry for another 4 minutes or until the internal temperature hits 165°F and the juices run clear.
Take out the chicken from the air fryer and serve it right away while juicy and tender.
