To cook London broil on the grill, the recommended cooking time is generally about 4 to 6 minutes per side, depending on the thickness of the meat and desired level of doneness. The internal temperature target is about 130-135°F for medium-rare. Usually, you preheat the grill to high (around 500°F), sear the steak for 4-6 minutes per side, and then let the meat rest for 5-10 minutes before slicing and serving. The resting step is important as it allows the juices to redistribute in the meat for a more tender result. Bringing the meat to room temperature before grilling and marinating it beforehand also improves flavor and texture.
Here is a summary of the grilling time and temperature:
Step| Time Per Side| Internal Temperature for Medium-Rare
---|---|---
Searing on grill| 4 to 6 minutes per side| 130-135°F (54-57°C)
Resting the meat for at least 5-10 minutes after grilling is recommended for best results.
This timing works for a roughly 2-inch thick London broil, which is typical. For thinner cuts, reduce the cooking time slightly, and use a meat thermometer to ensure it does not overcook.
