Season the fillet with salt and pepper.
On top of the fillets, place enough slices of potato to completely cover the surface of the fish.
Sprinkle some salt, pepper and parsley on top.
Heat an oven proof skillet with 1 tbs oil and place the fish on the pan, potato side down.
Quickly arrange some more potatoes on the other side and season with some salt and pepper.
Put it in the oven and bake it at 375 F for about 18 minutes.
Sprinkle some lemon juice on top and serve it hot!
