Mix Seasoning: In a small bowl, combine all seasoning mix ingredients (except olive oil).
Season Chicken: Coat each chicken breast evenly on both sides with the seasoning mix, massaging gently to ensure even coverage. Drizzle olive oil over the seasoned chicken and toss to coat.
Bake: Arrange chicken breasts on the prepared baking sheet, ensuring they are spaced out evenly. Bake for 18-20 minutes, or until the internal temperature of the thickest part reaches 165°F (74°C) using a meat thermometer.
