I discovered this technique for cooking salmon in Alison Romans’ cookbook, Dining In. Normally I cook salmon in anchovy butter for about 10 minutes. With this recipe you’ll cook it slow at a lower temperature for 20 minutes. It stays moist from the bath of olive oil and it’s so much easier to get it to just the right temperature without overcooking.

How to make slow cooked salmon
You won’t believe how easy this is to prepare.
Step 1:
Salt and pepper the fish and lay it in a pan not much bigger than your fish.
Step 2:
Pour olive oil into the pan so that it comes up the side of the fish but not so much that it covers it. Then place whatever citrus you like on top of the fish and in the olive oil.
Step 3:
Add whatever herbs you have on hand along with some red pepper flakes.
Seriously, this will take you 5 minutes.
Step 4:
Bake at a low temperature for 20-30 minutes depending on how thick your fish is. Aim for 145º with a meat thermometer depending on how rare you like your fish.
This is great if you’re having friends over. You can have it ready to go in the oven before they arrive and all you do is bake it. If you’re cooking for 1 or a smaller group, adjust the size of your pan so that it’s just slightly larger than your piece of fish. With this recipe you can serve fish with confidence that it won’t be overcooked.

Baked Lemon Salmon Recipe
Ingredients
- 1 lb salmon
- salt and pepepr

- 1 sprigs rosemary up to 2

Instructions

- Salt and pepper both sides of salmon and place in a baking dish. Top with sliced lemons and oranges that have been sliced very thin. ( I used a mandolin). Place fresh herbs on the top and around the salmon. Pour olive oil over the salmon so that it is resting in a pool of olive oil. The amount will depend on the size of your fish and baking dish. Sprinkle red pepper flakes over the salmon and also in the olive oil on the sides.
- Bake for 20-25 minutes depending on the thickness of the fillet. It should start turning opaque around the edges.
Barbara’s Tips + Notes
- Add just enough olive oil to cover the surface of the pan, it does not need to cover the fish.
- Slice the lemons and oranges very think, if you have a mandolin that works the best.
- You can substitute any fresh herbs you like.
