01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or lightly grease the surface.
02 - Pat the chicken breasts thoroughly dry with paper towels and arrange them on the prepared baking sheet.
03 - In a small bowl, combine olive oil, garlic powder, paprika, dried Italian herbs, onion powder, salt, and black pepper, stirring until a uniform paste forms.
04 - Rub the seasoning mixture evenly over both sides of each chicken breast, ensuring full coverage for balanced flavor.
05 - Bake for 18 to 25 minutes depending on thickness, until the internal temperature of the thickest portion registers 165°F on an instant-read thermometer.
06 - Remove the chicken from the oven and let it rest for 5 minutes to allow the juices to redistribute before slicing.
07 - Scatter chopped fresh parsley over the sliced chicken and serve with lemon wedges alongside.
