Salmon roasted in one piece — or, more precisely, a whole side of salmon — is a very practical solution. There are plenty of advantages to cooking fish this way, including the fact that it’s one of the easiest methods. The flavors still come through beautifully, and on top of that, you can literally have a very healthy meal on the table in half an hour.
But first, let’s look at whether we’re talking about half a salmon or a whole salmon here.
Half Salmon or Whole Salmon?
Technically, in this article I’m showing you how to roast half a salmon. This is the meat from one side of the salmon, with the backbone and head removed. It’s what we most often see today when people casually refer to “whole salmon,” or salmon roasted in one piece — meaning it is not cut into salmon steaks. I thought it was worth pointing this out because a whole salmon can also be roasted in the oven, but in that case we’re talking about the head still attached and both sides included. That is not really how it’s usually sold these days — and that’s a different recipe.
Why Is It Worth Roasting Salmon in One Piece?
As I wrote, there are lots of advantages to roasting salmon in one piece instead of cooking it in slices or as steaks:
- It’s much easier to prepare. As you’ll see in the recipe, you basically season it, put it in the oven, and you’re done.
- Buying half a salmon is cheaper than buying the same amount of fish already cut into slices.
- There’s no extra work involved. You don’t need to remove bones or clean it — as soon as you take it out of the packaging, it’s ready to bake.
- All you need is the oven and a baking sheet. You don’t need a skillet or any other piece of equipment.
- I also think it’s more economical in the sense that everyone can take as much fish as they’ll actually eat. The salmon isn’t cut up in advance: anyone who wants less can cut themselves a smaller piece after baking, while someone with a bigger appetite can have a larger portion.
How Many People Does Half a Salmon Serve?
This depends a little on where you buy the fish and how large it is. And of course, it also depends on how hungry the people you’re serving are and what else you serve alongside it.
But generally speaking, half a salmon is enough for 3–4 people. Three people will definitely be full from it, but if there’s enough side dish, another course, the group isn’t very hungry, or the fish is larger, it can also be enough for 4 people.
Preparing the Half Salmon
The best part is that half a salmon really needs no preparation at all. You don’t need to wash it — for the same reason I wrote about in the article on washing raw meat. You don’t need to remove the skin either, and the scales can stay on. The recipe shows you how to make it delicious!
What Makes a Good Salmon Roasted in One Piece?
This may be the point where people have the most different opinions. For many home cooks in particular, it’s hard to imagine fish any other way than cooked until firm — which technically means overcooked.
I don’t want to argue with anyone’s taste — cook salmon and enjoy it however you like it best. But it’s worth trying at least once the way most of the world likes it, or the way it would be served in a restaurant with a truly good kitchen.
In this case, the salmon is cooked through, with no raw parts, but the flesh flakes apart easily and stays truly juicy. In practice, this means you shouldn’t bake it even a minute longer than the point when the inside is cooked through at the thickest part. At that point, the flesh feels the same to the touch in both the thicker and thinner parts. It’s no longer jiggly, but just barely a little springy and firm.
According to this recipe and my own experience, that means 25 minutes, but it’s important to know that every oven is different and fish are not all the same. So it’s definitely worth checking the fish — especially the first time you make it. In practical terms, pull it out of the oven at the end of the baking time, and if you still see any more “translucent” areas, that part is still raw: bake it for a few more minutes. If the thickest part feels more jiggly to the touch than the thinner parts, bake it for a few more minutes as well.
Oven-Roasted Salmon in One Piece
Ingredients
- ½ salmon
- 2 cloves garlic
- ½ lemon
- Salt
- Ground black pepper
Instructions
- To make salmon roasted in one piece, preheat the oven to 350°F (175°C), using the regular bake setting, not convection. Pat the excess liquid off the salmon with paper towels. Line a baking sheet with aluminum foil, place a sheet of parchment paper on top, and put the fish on it, skin side down.
- Season the salmon with salt and pepper, press 2 cloves of garlic over it, and place 4–5 slices of lemon on top. Fish also absorbs a lot of salt, usually more than we think is enough at first.
- Put the salmon in the oven and bake for 25 minutes. If you still see any more “translucent” areas, that part is still raw, so bake it for a few more minutes. If the thickest part feels more jiggly to the touch than the thinner parts, bake it for a few more minutes as well.
Aluminum foil goes on the baking sheet, then parchment paper on top. Preheat the oven to 350°F (175°C).
Place the salmon on it, skin side down. You can salt the skin beforehand if you like — I didn’t.
Season the fish generously with salt and pepper. Press 2 cloves of garlic over it and place 4 lemon slices on top. Use the aluminum foil to make a little “dish” so the juices don’t run out.
Bake it in the oven for about 25 minutes — though this also depends on the thickness of the fish and on how everyone likes it. Don’t bake it for longer than 30 minutes.
