Creamy Horseradish Sauce


  • Season the tenderloins on both sides with salt and pepper.
  • Place them in a vacuum seal bag and vacuum seal them to remove all the air. You can also use the water displacement method (see notes in post above)
  • Heat a water bath to 125F degrees. Add the beef and cook for 3 hours.
  • Remove the beef from the water bath and take out of the bag. Pat it dry.
  • Heat a cast iron skillet over high heat until it starts to smoke.
  • Add the avocado oil (or any high smoke point oil) then add the beef.
  • Cook for 45-60 seconds per side, until a brown crust forms (be careful not to cook any longer otherwise it will be overcooked).
  • Remove and serve with the creamy horseradish sauce.

Creamy Horseradish Sauce

  • Combine all the ingredients in a bowl and mix well.
  • Store in a covered container in the fridge for 2-3 weeks.


  1. Pat the beef dry before searing it as that will help form a crust.
  2. Make sure the pan is smoking before adding the oil and beef.
  3. You can also grill the beef - just get the grill as hot as you can get it before cooking it.
  4. Be sure to buy fresh horseradish, NOT horseradish sauce.
