Ingredients (4 Servings)

5. Increase oven temperature to 230°C.
6. Add olives and rosemary to the pan; season with salt and pepper.
7. Clear four spaces in the pan and place a salmon piece in each.

Tip1: How to Skin a Fish Fillet
You can ask to have the skin removed from a piece of salmon or halibut fillet at the fish counter, but it is also easy to do it yourself.

1. Place the fillet, skin-side down, on a cutting board.
2. Use a thin sharp knife to cut between skin and flesh at the tip.
3. Grasp the skin with your free hand and ease the knife carefully between skin and flesh, keeping the knife pointed slightly toward the skin, until skin is removed.
   
   

Tip2: Serve with steamed green beans or broccoli florets and boiled new potatoes.
