First, preheat the oven to 180*C.
Sprinkle the red mullets with salt and ground pepper and then dust them with flour.
Line a pan with baking sheet and set aside. In a bowl pour in olive oil and then dip in the red mullets, one by one.
Arrange the fishes at the pan and drizzle over the lemon juice.
Cover them with baking sheet and bake at for 15 minutes.
Then, uncover them and turn on the grill and allow them to get a slightly red-brown colour, it will take 2 to 3 minutes.
Serve the fishes and drizzle them with the juices left on the pan. The juices left on the pan give them a mouthwatering flavor. Sprinkle them with parsley (optional).
