Preheat oven the oven to 450 degrees
Score the fish (three shallow, short cut marks on each side). Rub the cleaned whole fish and the baking sheet or dish you are using with the olive oil. Place the lemon slices and herbs into the score lines and the fish cavity and salt and pepper the entire fish along with the cavity and scores.
Place the fish in the hot oven for approximately 20 minutes. Test for doneness by lifting the flesh up from the bones by the dorsal fin. If the meat is opaque and not translucent, then it is ready to serve.
With a wide spatula, lift the entire fish off the pan onto a plate and serve as is. If you prefer, peel the skin off the upper side. Lift the meat off the bones with a cake spatula and put on a plate. Remove center bones and heel by lifting and discarding. Lift the bottom fillet onto the plate as well.
Enjoy!
