Preheat the air fryer to 380°F (193°C) for about 5 minutes.
Pat the chicken breasts dry with paper towels to remove excess moisture.
In a small bowl, mix together the olive oil, garlic powder, onion powder, smoked paprika, oregano, salt, pepper, and lemon juice until well combined.
Rub the seasoning mixture evenly over both chicken breasts, ensuring they are well coated.
Place the chicken breasts in the air fryer basket in a single layer, making sure they are not touching.
Cook the chicken at 380°F (193°C) for 12-15 minutes, flipping halfway through, 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. This helps retain the juices.
