We wash the fish well and trim them. We make scratches on it with a knife. And we place it in a baking tray lined with baking paper. For the sauce, we grate garlic over the juice of half a lemon. We add the spices. Finally, we add olive oil and mix.
With the help of a brush, we apply the sauce we prepared to the inside of the fish that we placed on the baking tray.
We put one sliced lemon and one onion into each.
We apply the remaining sauce on the fish, between the parts we drew with a knife.
We cover the tray with aluminum foil and leave it to bake in the oven at 200 degrees.
After baking with foil for about 45 minutes, we remove the foil and bake for 15 minutes until golden brown.
