Notes

  • Tips and Tricks Marinate long enough. I recommend marinating the London Broil for the maximum 12 hours. This will infuse the steak with TONS of flavor and optimal juiciness. On the opposite end of the spectrum, don’t marinate London Broil much longer than 12 hours or the muscle fibers can break down and become mushy. Don’t overcook. Don’t overcook your London Broil or it won’t be as juicy. Use a meat thermometer to check for doneness and broil to 140 degrees for medium. The steak will rise to 145 degrees after it rests. Most flank steaks will be done in 4-6 minutes per side, but if your flank steak is on the thick end of the spectrum, it can take up to 8 minutes per side. Use a meat thermometer The ONLY way to cook your London Broil to perfection is with a meat thermometer, otherwise it is easy to overcook your steak. A meat thermometer also allows you to accurately cook chicken, beef, pork, etc. to the perfect temperature for optimum juiciness every time. Let London Broil rest. While the steak cooks, the juices are forced away from the heat to the middle of the meat. The resting time allows for the redistribution and reabsorption of the juices throughout the whole steak for optimal flavor and juiciness. If you don’t allow for this calming period, valuable juices will seep out and be lost when you slice into the steak, resulting in less juicy beef. Slice London Broil across the grain. This will shorten the muscle fibers for tender steak. Salt and pepper to taste. If you feel like the London Broil is missing, it is simply salt and pepper. Season to taste so the steak is perfect for YOU!! Leftovers: See post for lots of fun ways to serve leftover London Broil.
