Directions

4. 4
   Season the potatoes liberally with salt and pepper, spread them evenly, and put the pan in the oven.

7. 7
   Top the potatoes with the fish, drizzle with the remaining oil or butter, and sprinkle with some more salt and pepper.
8. 8
   Broil until the fish is done, 6 to 10 minutes depending on its thickness (a thin-bladed knife will pass through it easily).
