What could be better than perfectly cooked, flaky and tender salmon? If you want to create this, then the best way to do it is with sous vide cooking. The good news is that it is very easy to do. It is very unlikely that you will overcook your salmon and you will be able to cook the fish quickly. All you need is a sous vide cooker, so be sure to read our review of the best sous vide machine.
Cooking your salmon sous vide will take a bit longer than conventional methods, but it is well worth the wait. You will never get the same results with traditional cooking that you can with sous vide. Your salmon will be cooked at a precise temperature, and your fish will be a lot tenderer. Your salmon will be cooked evenly, and all of the juices of the fish will be maintained.
It Is A Good Idea To Brine Your Salmon
If you have cooked salmon using traditional methods, you probably will have noticed a white curd is discharged. This is called albumin, and this is very likely to be pushed out if the salmon is poached, smoked or canned.

If you brine your salmon then you will reduce the chances of the albumin being excreted. To make this brine you will need 2 cups of ice water, 2 tablespoons of olive oil and 2 tablespoons of salt (kosher is better). This will be sufficient for cooking 2 x 8 ounce fillets of salmon.
You will need to dissolve the salt in the water first, and then add this to a cooking bag. Add the olive oil to this and stir well. Then place the fillets of salmon into the bag and seal – if you are using zip lock bags then you will need to expel the air from the bags. Place the bag(s) in the refrigerator for a minimum of ten minutes and up to 30 minutes. Seasoning can also be added at this stage.
After the time is up, remove the salmon fillets from the bags and dry them by patting with a paper towel. Then place the fillets into new cooking bags. Ensure the air is removed by using a best sous vide vacuum sealer or by using air displacement. You will get better results from a vacuum sealer.
Brining your salmon is highly recommended as not only does it stop the albumen leaving your fish, it also seasons your salmon, so there is no need to add additional seasoning. The brine will also protect your salmon fillet from overcooking.
Cooking Your Salmon
You will find various suggestions on how to cook your sous vide salmon. The important things here are the temperature and amount of time that you cook for. You will need to make your own decision on the temperature depending on your own tastes.
Traditional Sous Vide Salmon
After several cooking attempts at different temperatures and times, we would recommend the following cooking temperatures and times:
If you like your salmon tender then set your cooking temperature to 104°F (40°C). Cook the salmon sous vide for 40 minutes. If you want tender and flaky salmon (which is highly recommended), then your cooking temperature needs to be set to 122°F (50°C) and again you will need to cook for 40 minutes. For a well done salmon fillet, the cooking temperature needs to be 140°F (60°C) and the cooking time the same at 40 minutes.
Most types of fish can be cooked to a flaky and tender consistency at 122°F. It is possible to cook a number of pieces of salmon in the same sealed bag, but you will need to cut into portions before cooking as you will not get an even cook with a whole fish.
For the best results, use fillets that are around 1.5 inches thick. You can cook thinner pieces, and you will need to cook these for around 30 minutes instead of 40 minutes. If your salmon is thicker than 1.5 inches then add a few minutes to the cooking time. There is no reason why you cannot check on your fish while it is cooking, and place it back in the water if it is not cooked enough.
If you exceed the 40 minutes recommended cooking time it is unlikely to have much of an effect on your salmon. If you want, you can cook your salmon for an hour and still achieve great results.
To cook your salmon, set the temperature on your sous vide machine and wait until the water has reached the desired temperature. Then add your salmon fillets and set your desired time.
After your salmon has cooked sous vide, you can use a skillet for searing with a torch to achieve the best results. A few minutes before your sous vide salmon is finished, heat a skillet with a couple of tablespoons of olive oil.
Take the salmon fillets out of the sous vide bags and add each fillet to the skillet. Use a high heat and go for searing at around 45 seconds each side. Make sure that you do both sides. Immediately serve and eat. Don’t leave the salmon in the skillet or on the plates for too long, as the juices will be lost and the fish will become dry.
If you are not a fan of crispy salmon, you can remove the skin before you cook your fillets. You will not need any searing in this situation, and you can serve the fillets straight out of the water oven.
Fresh Salmon with Butter and Olive Oil Using Sous Vide
Here is the recipe to create a fresh salmon seared on butter and olive oil.
- Salmon fillets
- Table/kosher salt
- Citrus zest (optional)
- 3 tbsp olive oil
- 1 tbsp Butter
- 2 cloves Garlic
- Prepare your fillets by removing its pin bones if it still has bones. Use tweezers or needle-nose pliers toeffectively remove the unwanted element. You should have soaked it in a brine beforehand to keep its tenderness after cooking. You may do so by dry brining it with water and salt for about half an hour. You may want to keep the skin of the fish intact to effectively sear it afterward.
- Remove the brine from the bag and submerge the sealed vacuum bag in the preheated water. You may want to use vacuum sealers that are effective in removing unnecessary air in the bag. Some reviews online will insist that a ziplock bag will be enough to produce a quality fish meat. However, that will not always be the case. Some bags and vacuum containers can process meat and fish that retains its integrity even after being submerged in the water.
- For our purposes, the water should be heated to 120°F or 49°C to keep the fish flaky without having to remove much of its natural moisture. Maintain the temperature effectively with the use of sous vide machines such as immersion circulators and precision cookers. Make sure that this appliance will provide you with maximum aid and autonomy in controlling the temperature, as cooking fish meats such as salmon with the use of sous vide method can prove to be extremely difficult without the proper control.
- After the predetermined time, remove the fish from the bag. Extreme care is needed to maintain the integrity of the meat. The fish by then have become more flaky and delicate, and without the proper care, some flakes will fall off or be left behind.
- When proceeding with the searing, heating the meat over a pan with olive oil and some butter for an about 2 minutes each side will produce a nice, golden brown finish on the surface of the meat.
Different Salmon Will Produce Different Cooking Results
Tests have proven that when you cook different types of salmon you will get different results. They should all taste great, but the textures and flavors will be different. When you cook a Norwegian salmon for example, you will find that it will be very delicate to handle after cooking. This can make it difficult when it comes to searing. The taste will be excellent though so persevere with this. With a wild Coho salmon it should come out a lot firmer after sous vide cooking and the searing will be easy.
