Sous Vide Steak with Béarnaise Sauce

Sous Vide Steak with Béarnaise Sauce

By Sophie


Serves 2

Béarnaise Sauce

  • 1 tablespoon (4g) chopped tarragon (fresh French tarragon is best)
  • 1 tablespoon (5g) chopped shallot
  • 3 peppercorns
  • 1 tablespoon (15ml) white wine vinegar
  • 1/3 cup (80 ml) dry vermouth  or dry white wine
  • 2 egg yolks
  • 1 tablespoon (15ml) water
  • 5 tablespoons (75g ) butter, melted


  1. Fill and preheat the SousVide Supreme to 174°F/79°C.
  2. Put the tarragon, shallot, peppercorns, white wine vinegar and vermouth into a saucepan and cook over a medium to high heat. Allow to simmer and reduce until there are one and half tablespoons of liquid remaining.  Take the pan off the heat and set aside.
  3. Lightly beat the egg yolks in a bowl. Strain the tarragon reduction into the egg yolks and discard the leftover tarragon and shallots.
  4.  Add the melted butter and water to the egg yolks and whisk everything together with a fork or small whisk.
  5. Pour the mixture into a (quart/0.95 liter) zip-closure cooking pouches, and use the displacement method (Archimedes’ principle) to remove the air and zip the seal closed. Once the bag is zipped closed, submerge the pouch in the preheated water bath and leave to cook for 45 minutes.
  6. Once the béarnaise is cooked, pour it into a clean bowl and whisk together to form a smooth sauce. If I am cooking a steak, I like to leave the béarnaise warm over a saucepan of just boiled water on a low heat until I am ready to serve. If the béarnaise gets too thick, add a few drops of boiling water to thin it out.

Sous Vide Steak

  • 2 (8 ounce/240g) steaks
  • Salt and pepper, to taste
  • 1 tablespoon (15 ml) peanut oil, to fry
  1. Fill and preheat the SousVide Supreme to  your  preferred degree of doneness (120F/49C rare; 134F/56.5C medium rare; 140F/60C medium; 150F/65.5C medium well)
  2. Pat the steaks dry with kitchen paper (paper towel) and season them on both sides with salt and pepper. Smoked salt is a nice alternative to give the steak a slightly smoky crust.
  3. Put the steaks into a food grade cooking pouch and vacuum seal.
  4. Submerge the pouch in the water bath and cook for at least one hour and up to 8 hours. (For tougher cuts or grassfed steaks, the longer you leave them, the more tender they will become.)
  5. Remove steaks from pouch and pat dry with some clean kitchen paper (paper towel).
  6. Heat the oil in a pan over a high heat.
  7. Quickly sear the steaks on both sides to achieve a rich brown crust.
