LONDON BROIL began as a preparation process of marinating and then searing or broiling the meat at a HIGH temperature, NOT a cut of meat.  The process became so popular that eventually grocery stores began selling top round under the name “LONDON BROIL”.  Top-round steak, is sometimes sold as “London broil” or “Flank steak” is the traditional cut of beef used for London broil because it takes so  well to marinades.


1 (2 pound) London broil top-round steak
FRESH ground sea salt and black pepper
1/4 cup avocado oil
Juice of 1 lemon
3 tablespoons packed dark brown sugar
1 tablespoon Worcestershire sauce

  • Place pan on middle rack in the center of the oven and broil 10 to 15 minutes (depending on desired doneness), until top is charred.
  • Flip and broil 10 to 15 minutes more (depending on desired doneness), until internal temperature reaches 125° for medium rare.
