Ingredients

  • 1 pound flat-iron steak
  • 1/2 teaspoon kosher salt or to taste
  • 1/4 teaspoon black pepper or to taste
  • 1/4 teaspoon garlic powder
  • 1 tablespoon olive oil

Instructions

  • Add water to the sous vide container or a large pot, and set the Sous Vide Precision Cooker to (135°F/57°C) for medium-rare doneness. If you’d like to cook to other doneness, see the temperature chart in the post above.
  • Season your flat iron steak generously with salt, pepper, and garlic powder.
  • Place the seasoned steak to a zip-lock bag.
  • Seal all but one corner of the bag, and slowly place it into the water bath. Make sure everything below the zip-line is covered by water, and push the air out. (If the water is already heating up, you can use a kitchen tong to push the bag into the water). Then seal the rest of the bag. (This technique is called “water displacement method”).
  • Lave the vacuum-sealed bag in the sous vide water bath. Make sure it is fully submerged.
  • Cook for 2 hours.
  • When the timer goes off, remove the bag from the water bath and transfer it to an ice bath (or refrigerator). Let it chill for about 10 minutes.
  • Remove the steak from the bag and wipe off the moisture with paper towels. (Make sure to pat dry the surface completely.)
  • Season with more salt and pepper if necessary.
  • Place the cast-iron skillet or grill on medium-high heat, and add olive oil. Once hot, add the steak and sear about 1 minute per side. (If you use grill, you can brush the oil on the steak).
  • Slice against the grain and serve immediately.
