  • Immersion circulator/sous vide cooker



  • Set your immersion circulator/sous vide to desired finished temperature (I recommend 135 degrees) for 2 hours and 30 minutes.
  • Liberally season your steak with salt, pepper, and garlic powder.
  • Vacuum seal your steak. If doing more than one, seal them separately.
  • Place into the water bath, making sure the steak is fully submerged in water.
  • When time is up, remove the steak. Allow to cool for 10 minutes before opening.
  • Heat up a grill or a cast iron pan.
  • When hot, cook the steak for 1-2 minutes per side just to get it hot.
  • Rest for 5 minutes. Cut slices against the grain and on the bias.
