A London Broil roast is dry brined overnight, seasoned and then cooked Sous Vide at 129F for two hours. After a quick sear the steak is thinly sliced and served.
Salt the London Broil, place on a plate and let it dry brine in the refrigerator for at least eight hours.
Rinse the meat and pat dry with paper towels.
Optional: brush both side of the meat with Liquid Smoke.
Season the beef with a low salt steak rub.
Vacuum seal the steak in a sous vide bag.
Immerse the bagged steak into a water bath maintained at 129F and cook for two hours.
Remove the London Broil from the bag and sear in a cast iron skillet for 90 seconds per side.
Notes
London Broil is usually a cut of Top Round. This piece of beef comes from a working muscle on the steer and as a result it is very flavorful but lean and tough. The combination of a dry brine and sous vide cooking helps make the steak tender.
