Turns out, Sous Vide Black Cod Fillets is an easy method to make some delicious fish!

True confession: cooking seafood always stressed me out in the past. Maybe it’s ‘cause proteins from the sea are extremely perishable and seem to overcook in an instant. Plus, have you seen the price of high quality seafood lately?! Marone!

For many moons, my tame kitchen adventures involving fruits de mer only revolved around salmon and shrimp…but not anymore!

Armed with a SousVide Supreme and the conviction that I gotta get more healthy omega-3’s in my belly, I jumped in the deep end and joined a seafood CSA. I’m excited and a tad nervous that we’re getting a weekly delivery from Siren SeaSA – a sustainably-harvested local seafood CSA in the San Francisco Bay Area – but I’m ready for a challenge!

For my first delivery, I received two be-YOO-tiful black cod fillets.

Time to make Sous Vide Black Cod Fillets!

Serves 3

Ingredients:

  • 1 pound of black cod fillets, skin-on and scaled
  • 3 tablespoons of ghee or grass fed butter
  • 3 sprigs of thyme
  • 2 tablespoons of table salt (double the amount if using Kosher salt)
  • 1 cup of water
  • Kosher salt
  • Fleur de sel
  • Lemon wedges

Equipment:

  • All of my recommended kitchen tools are listed here.

Method:

I preheated the oven to 300 F, filled and heated my SousVide Supreme to 125 F, and sharpened my kitchen knife.

I combined the table salt and water in a measuring cup to make a 10% brine.

Then, I divided the big fillet into two portions (3 fillets total), carefully removed the skins from each piece…

I grabbed a pair of clean tweezers and removed the pin bones from the fillets.

What a pain in the butt!

Then, I put the boneless and skinless fillets in a Ziploc bag, poured in the brine, and let them sit on a bowl of ice in the fridge for 10 minutes.

You don’t have to brine the fillets but it helps with the flavor AND you won’t get the unsightly white albumin all over the finished product.

After the brining was finished, I removed the fillets…

The crispy skin coupled with the moist, buttery flesh was really yummy!
