Sous Vide Marinated Flank Steak

This sous vide steak with marinade turns out incredibly tender. I like to grill the flank steak afterward for a couple of minutes for extra flavor.

Prep Time:

Total Time:
8 hrs 15 mins


  • 2 tablespoons low-sodium soy sauce (such as Bragg®)

  • 2 tablespoons honey

  • 2 tablespoons olive oil

  • 1 tablespoon red wine vinegar

  • 1 clove garlic, finely chopped

  • 1 (8 ounce) flank steak (about 1-inch thick)


  1. Combine soy sauce, honey, olive oil, vinegar, and garlic in a flat glass dish.

  2. Trim any surface fat from steak. Place steak into soy sauce mixture; turn to coat. Allow to marinate in the refrigerator for about 5 hours, turning occasionally.

  3. Place a heat-resistant pad underneath a large pot filled with water. Attach a sous vide precision cooker to the pot and preheat water to 140 degrees F (60 degrees C).

  4. Remove steak from marinade and shake off excess liquid; discard marinade. Place steak into a food-grade polyethylene bag and vacuum seal or use the water immersion method to remove all air. Submerge the bag in preheated water; set the timer for 3 hours.

  5. When the timer is up, remove steak from the bag and pat dry with a paper towel.

  6. Preheat an outdoor grill for high heat and lightly oil the grate.

  7. Place steak on the preheated grill and cook on one side for 2 to 3 minutes. Cut in half and serve.


The flank steak tastes best if cut against the grain into thin slices.
