Preheat your oven to 425°F (220°C).
Lightly grease a baking dish or line a baking sheet with parchment paper.
Pat the chicken breasts dry with paper towels.
Rub both sides with olive oil.
Season evenly with garlic powder, paprika, Italian seasoning, onion powder, salt, and black pepper.
Arrange the chicken in a single layer.
Bake for 18 to 22 minutes, depending on thickness, until the internal temperature reaches 165°F (74°C).
Remove the chicken from the oven and let it rest for 5 minutes before slicing.
Sprinkle with fresh parsley and serve warm.
