Preheat your air fryer to 380°F (193°C) for 5 minutes.
In a mixing bowl, combine olive oil, garlic powder, onion powder, smoked paprika, salt, and black pepper. Stir until well mixed.
Pat the chicken breasts dry with paper towels.
Coat each chicken breast with the olive oil mixture, ensuring they are well-covered.
Place the chicken breasts in the air fryer basket in a single layer, avoiding overcrowding.
Air fry the chicken breasts at 380°F (193°C) for 10 minutes. After 10 minutes, flip the chicken breasts over.
Continue cooking for an additional 10 minutes, or until the internal temperature reaches 165°F (74°C).
Once cooked, remove the chicken from the air fryer and let it rest for 5 minutes before slicing.
Drizzle with fresh lemon juice and garnish with herbs if desired, then serve.
