Remove chicken breasts from refrigeration 30 minutes before cooking to allow them to reach 50-55°F internal temperature.
Position oven rack in center position and preheat oven to 425°F (218°C). Allow at least 20 minutes for complete preheating.
Line sheet pan with parchment paper and apply a light coating of cooking spray.
Pat chicken breasts completely dry with paper towels to remove excess moisture.
In a small bowl, combine salt, pepper, garlic powder, onion powder, and dried herbs. Brush chicken with oil, then apply seasoning mixture evenly on both sides, pressing gently to adhere.
Arrange chicken breasts on sheet pan with 2-inch minimum spacing between pieces. Position thicker ends toward the outer edges of the pan.
Place sheet pan in oven and roast at 425°F for 10 minutes to develop exterior browning.
Without opening the oven, reduce temperature to 375°F (190°C) and continue cooking for 10-15 minutes.
Test internal temperature at the thickest part of each breast. Target 163°F (73°C) as carryover cooking will raise final temperature to 165°F.
Transfer sheet pan to cooling rack and tent loosely with foil. Allow chicken to rest for 5-7 minutes before slicing to redistribute juices.
