Step 1: Prepare the Chicken

1. If your chicken breasts are thick on one side, use a meat mallet or rolling pin to pound them to an even thickness. This ensures they cook evenly.
2. Pat the chicken breasts dry with paper towels to help the seasoning stick.

Step 2: Season the Chicken

1. In a small bowl, mix together the garlic powder, paprika, onion powder, oregano, salt, and black pepper.
2. Drizzle the chicken breasts with olive oil, then sprinkle the seasoning mixture evenly on both sides, pressing gently to adhere.

Step 3: Preheat the Air Fryer

1. Preheat your air fryer to 375°F (190°C) for 3-5 minutes. Preheating ensures the chicken cooks evenly and develops a nice crust.

Step 4: Cook the Chicken

1. Place the seasoned chicken breasts in the air fryer basket in a single layer, ensuring they are not touching. Cook in batches if necessary.
2. Air fry for 12-15 minutes, flipping halfway through, until the internal temperature of the thickest part of the chicken reaches 165°F (74°C). Use a meat thermometer for accuracy.

Step 5: Rest and Serve

1. Remove the chicken breasts from the air fryer and let them rest for 5 minutes before slicing. This allows the juices to redistribute, keeping the chicken moist.
2. Serve immediately, or store for later use in wraps, salads, or grain bowls.
