Preheat your air fryer to 375°F (190°C) for about 3 minutes.

In a small bowl, combine olive oil, garlic powder, onion powder, paprika, thyme, oregano, salt, and pepper. Mix well to form a marinade.

Place the chicken breasts in a shallow dish or resealable plastic bag. Pour the marinade over the chicken, making sure each piece is well coated. Allow the chicken to marinate for at least 15 minutes, or up to overnight in the refrigerator for maximum flavor.

Once the chicken has marinated, remove it from the refrigerator and let it sit at room temperature for about 10 minutes.

Lightly spray the air fryer basket with cooking spray to prevent sticking. Place the chicken breasts in the basket in a single layer, leaving some space between each piece to allow for proper air circulation.

Cook the chicken breasts in the air fryer at 375°F (190°C) for 12-15 minutes, flipping halfway through the cooking time, until the chicken is golden brown and reaches an internal temperature of 165°F (75°C) when tested with a meat thermometer.

Once cooked, remove the chicken breasts from the air fryer and let them rest for a few minutes before serving.

Serve the air fryer chicken breasts hot with your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad. Enjoy your delicious and healthy meal!
