Start by patting the chicken breasts dry with paper towels. This helps the seasoning stick and ensures a crispy finish.
In a large bowl, combine the chicken breasts with olive oil, lemon pepper seasoning, garlic powder, and salt. Toss until the chicken is evenly coated with the seasoning.
Preheat your air fryer to 380 degres F (193°C) for about 3 minutes. This step ensures the chicken starts cooking immediately, sealing in the flavors.
Place the chicken breasts in the air fryer basket in a single layer, making sure they don't overlap. This allows for even cooking and crisping.
Air fry the chicken breasts for about 10-12 minutes, then flip them over and cook for an additional 10-12 minutes, or until the internal temperature reaches 165°F (74°C) when checked with a meat thermometer. Cooking times may vary based on the size and thickness of the chicken breasts, so adjust accordingly.
Once cooked, let the chicken rest for a few minutes before slicing. This allows the juices to redistribute, ensuring the chicken is moist and flavorful.
Garnish with fresh lemon slices, if desired, and serve hot. The lemon slices can be squeezed over the chicken for an extra lemony kick.
