Preheat the oven to 400°F (200°C).

In a mixing bowl, combine olive oil, salt, black pepper, garlic powder, paprika, and oregano.

Coat the chicken breasts with the seasoning mixture, ensuring they are evenly covered.

Place the seasoned chicken breasts in a baking dish.

Bake in the preheated oven for 20-25 minutes, or until the internal temperature reaches 165°F (75°C).

Remove from the oven and let rest for 5 minutes before slicing.
