Preheat your oven to 450 degrees F. Line a baking dish with foil.
Generously spray both sides of each chicken breast with olive oil, and sprinkle them with the seasonings.
Bake, uncovered, until the internal temperature reaches 160-165 degrees F and juices run clear when pierced with a fork, about 20 minutes. The center of the chicken breasts should be white and opaque.
Transfer the baked chicken breasts to a platter. Loosely cover with foil and allow to rest 5-10 minutes before slicing and serving.
If your chicken breasts are much larger than 8 oz, you will need to bake them for longer, probably around 30 minutes. So check after 20 minutes. And if you need to bake them for longer, either flip them or loosely cover with foil, to prevent the tops (and especially the spices) from burning in the hot oven.
