Grilled London Broil
London Broil. It’s ain’t from London, and it ain’t broil, but it is delicious. You’ll usually see flank steak or top round labeled as a London Broil at your local butcher shop… even though the term London Broil refers to the cooking method not the cut of meat. Both flank steak and top round are inherently tough, so you have to marinate them, but that just adds to the flavor.
We up the BBQ Pit Boys for a grilled London Broil recipe. You can watch the video or just follow the instructions below. Man your grill fellas.
Meat:
2 – 3lb top round steaks.
Marinade:
1. 12 to 16 oz beer
2. Half cup of extra virgin olive oil
3. 1 tsp cayenne pepper
4. 1 tbsp garlic powder
5. 1 tsp onion powder
6. 2 tbsp wostershire sauce
7. 1 tbsp ground peppercorn
8. 1 tbsp prepared horseradish
9. Juice of 1/2 lemon
Directions:
Not from London
Trim the fat from the steaks.
Mix all marinade ingredients
Put steaks in a ziploc bag with marinade.
Marinate in cooler or fridge for 4-6 hours, or overnight. Longer is better.
(Marinade helps tenderize the meat and help break down the muscle fibers)
After marinating prepare a medium heat charcoal fire. (or gas, but you know what will taste better)
Note: Too much heat will burn your steaks.
Grill steaks over medium heat for about 8 minutes per side, depending on the thickness.
Use your meat thermometer or the finger test for doneness. 130-135 degrees = medium-rare.
Remove the steaks from the grill when they are done. Let the meat sit for about 5 minutes before cutting.
Cut across the grain. Slice thin. Plate it up and enjoy.
