Equipment

  • sous vide portable cooker
  • cast iron skillet

Ingredients

For The Steak

  • 1 ½ pound flat iron steak
  • ½ tablespoon kosher salt
  • ½ tablespoon fresh ground black pepper
  • 1 tablespoon olive oil

For the Sauce

  • 1 small shallot diced
  • 4 cloves garlic minced
  • 2 medium tomatillos diced
  • 2 red jalapenos seeded and diced
  • 3 basil leaves chopped
  • ¼ cup olive oil
  • 2 tablespoon red wine vinegar
  • 1 teaspoon kosher salt
  • 1 teaspoon black pepper

Instructions

Cooking The Steak

  • Attach the Anova Sous Vide Cooker to the container of your choice, and preheat a sous vide bath to 136°F for medium-rare
  • Season the steak lightly with salt and pepper. Vacuum seal the steak if using a vacuum sealer. Otherwise usa a ziplock bag; partially seal it removing as much air as possible, then use the water displacement method by placing the bag in the water (always keeping the opening above the water line) to push the rest of the air out before sealing it.
  • Submerge the pouch in the water oven and cook for 3 hours.
  • Remove the steak from the pouch and pat it dry with paper towels.
  • Heat cast iron skillet on high heat, add½ tablespoon oil and then sear the steak about 1 minute a side.
  • Remove the steak and let rest for 5-10 minutes. Letting the steak rest is crucial so don't skip this step
  • Slice the steak against the grain and arrange on serving plates.

Making the Sauce

  • Place all ingredients in blender or food processor and pulse to make coarse paste. Alternatively, just chop everything finely via a knife and mix well in a bowl.
