Prep Time 5 mins
Cook Time 6 hrs
Total Time 6 hrs 35 mins
Servings 4


  • 2 pounds of top round cut of meat (you can also use flank steak)
  • 3 tablespoons of balsamic vinegar
  • 1 tablespoon of honey
  • 3 tablespoons of soy sauce
  • 2 tablespoons of Worcestershire sauce
  • 2 tablespoons of olive oil
  • 3 minced garlic cloves
  • 2 tablespoons of mustard sauce (optional)
  • Salt and pepper to taste


  • Marinade the steak by mixing the balsamic vinegar, honey, soy sauce, Worcestershire sauce, minced garlic, 1 tablespoon of olive oil, and mustard in a zip-lock bag with the steak.
  • Make sure the steak is completely covered with the marinate sauce. Leave it in the refrigerator for 30 minutes to 2 hours. This will tenderize and soften the fibers of the steak.
  • To prepare the Sous vide, you will first need to fill its container with water, then adjust the temperature to 133°F (56°C).
  • Transfer the steak after marinating into a new zip-lock bag.
  • Now, for the ‘Water displacement’ technique, you will need to 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.
  • Cover the Sous Vide with several aluminum foils completely to avoid the evaporation of water. Leave it to cook for 6-8 hours.
  • When the timer is off, transfer the steak from the bag to the refrigerator to cool off for 10 minutes.
  • Remove all the excess moisture of the steak with a paper towel, sprinkle some salt, and pepper to taste and drizzle some olive oil on both sides.
  • Sear each side of the steak on a hot skillet put on a medium-high heat flame for 1 minute on each side.
  • Slice the steak and dish it up with some creamy mashed potatoes and cooked vegetables.
