Herb Crusted Sous Vide Flank Steak
Flank steak is one of my favorite cuts to sous vide. This lean, sometimes a little on the tough side, steak benefits from a low and slow cook and a hot sear. I love to do an herby salt to season this steak, but a marinade is also a great way to go.
Ingredients
- 2 tbsp kosher salt
- 1 tbsp finely chopped fresh oregano
- 1 1/2 lbs flank steak
- 2 tbsp ghee, for searing
Instructions
- Preheat water bath using immersion circulator to your desired temperature. 123-127 F for rare, 128-134 F for medium rare, 135-140 F for medium, 141-150 F for well done. I prefer 129 degrees F.
- Combine the kosher salt and oregano in a small bowl. Set aside.2 tbsp kosher salt, 1 tbsp finely chopped fresh oregano
- Using a sharp pairing knife, score the flank steak by dragging the tip of the knife diagonally across the surface of the steak in one direction, then in the opposite direction. Repeat on the other side of the flank steak.1 1/2 lbs flank steak
- Season the scored flank steak with the kosher salt oregano mixture well on both sides. You likely will not use all the salt. Remaining salt can be added to a jar and stored for future use.
- Add the steak to a vacuum seal bag and vacuum seal. If you don't have a vacuum sealer, add to a freezer-safe zipper-top gallon-sized bag and use another air removal method.
- Add the vacuum sealed steak to the preheated water bath and cook for 2-4 hours.
- When the steak is done cooking, remove the bag from the water bath and the steak from the bag. Using paper towels or a clean dish cloth, pat it dry on both sides.
- Heat a cast iron skillet over high heat until smoking. Add the ghee. Sear the steak on both sides until a deep brown, 30 seconds to 1 minute.2 tbsp ghee
- Slice the steak into 1/2 inch slices against the grain. Sprinkle with a little of the remaining salt and serve.
Notes
- Swap the herby salt for any rub or marinade that you want.
- Don't have oregano? You can use any other "hard" herb in its place (rosemary, thyme, or sage).
- Serve this flank steak with chimichurri for a real winner of a meal!
