When cooking seafood or delicate items, I don’t like using my vacuum sealer. The vacuum sealer sucks out the air too harshly, which can damage the delicate fish, or just make the fish misshapen during cooking. Instead, I use the water displacement method.

Submerge the bag until just under the seal.

Seal bag. The water will displace the air, resulting in a bag and seal that’s good enough for sous vide.

Clip to edge of pot.

Set the sous vide to 104F/40C. Let cook for 30 minutes at temperature.

When Miso Salmon is done, remove salmon fillets (be careful not to break the fish) and reserve the remaining miso sauce in the bag. Pat the fillet with a paper towel and wipe off some of the miso. If you don’t the miso will burn in the pan when you sear.

Sear both sides of salmon in a bit of cooking oil.

Serve with the remaining miso sauce, top with sesame seeds or green onion.

Sous Vide Salmon Recipe

You can use any fish you'd like. The recipe is for fish pieces about 1.25" thick. If you are using thicker pieces of fish, increase sous vide cooking time to 45 minutes.
Prep Time 5 minutes
Cook Time 1 hour 6 minutes
Servings 4


  • 2 tablespoons miso paste
  • 2 tablespoons Japanese sake
  • 2 tablespoons mirin (sweet rice wine)
  • 2 tablespoons butter
  • 4 pieces salmon (about 5 ounces each)
  • 1 tablespoon cooking oil
  • 1 green onion, very thinly sliced or sesame seeds (optional)


  • In a bowl, whisk together the miso, sake and mirin until smooth paste forms. Spread mixture over each salmon fillet. Add the salmon to a gallon freezer bag, insert the pieces of butter. Set sous vide to 104F/40C. Once at temperature, cook for 30 minutes.
  • When salmon is done, remove from bag, carefully pour miso butter mixture in a bowl and reserve. Pat the salmon pieces dry with a paper towel to wipe off excess moisture
  • Heat a frying pan over medium high heat. When hot, swirl in the cooking oil. Add the salmon pieces and sear each side for 1 minute. Remove the salmon to a serving plate. To the frying pan over low heat, pour in the reserved miso butter sauce and cook for 30 seconds, to thicken. Pour sauce over salmon and top with green onions or sesame seeds, if desired.
