01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Pat the chicken breasts dry with paper towels to ensure proper seasoning adhesion.
03 - In a small bowl, combine olive oil, salt, pepper, garlic powder, paprika, thyme, and onion powder until well blended.
04 - Rub the seasoning mixture evenly over both sides of each chicken breast, coating thoroughly.
05 - Place seasoned chicken breasts on the prepared baking sheet, leaving space between each piece for even air circulation.
06 - Bake for 20–25 minutes, or until the internal temperature reaches 165°F when measured with an instant-read thermometer and juices run clear.
07 - Remove from oven and let the chicken rest for 5 minutes before slicing to retain juices.
08 - Garnish with chopped fresh parsley and serve with lemon wedges alongside roasted vegetables, mashed potatoes, or a crisp salad.
