  • 1 pound of flat iron steak
  • ½ teaspoon of salt
  • ½ teaspoon of freshly ground pepper
  • ¼ teaspoon of garlic powder
  • 1 tablespoon of olive oil


  • To prepare the Sous vide, you will first need to fill its container with water, then adjust the temperature to 135°F (57°C). Leave it to preheat.
  • Season your Flat iron steak by sprinkling salt, pepper, and garlic powder generously on both sides.
  • Now, for the ‘Water displacement’ technique, you will need to put your steak in a zip-lock bag, then close the bag completely except one corner to allow air to come out. Dip the bag in a water filler container, keeping the zip-line above the water surface. Close the zip-line completely.
  • Dip the bag completely into the sous vide container. Let it cook for 2 hours.
  • When the time is done. Transfer the bag with the steak to cool off in the refrigerator for 10 minutes.
  • Remove excess moisture from the steak with a paper towel. Sprinkle some salt and pepper according to taste.
  • On a hot iron skillet, put on a medium-high flame, sprinkled with the rest of the olive oil, sear your steak for 1 minute on each side.
  • Slice the meat against grain into strips. Dish it up with mashed potatoes, veggies, Fruit Salsa, Steamed Broccoli, or Sous Vide Potatoes. Enjoy!
