Preheat your oven to 375°F (190°C).
In a mixing bowl, whisk together olive oil, lemon juice, lemon zest, garlic, oregano, paprika, salt, and pepper.
Place the chicken breasts in the marinade, ensuring they are fully coated.
Let them marinate for at least 15 minutes, or up to 2 hours in the fridge for more flavor.
Transfer the marinated chicken breasts to a baking dish. Pour any remaining marinade over the top.
Bake in the preheated oven for 25–30 minutes, or until the internal temperature reaches 165°F.
Let the chicken rest for 5 minutes before slicing.
Garnish with fresh parsley or dill and serve with your favorite sides.
