How to Slow-Cook a London Broil
- 1). Thaw the meat in the refrigerator for 12 to 24 hours. You can also thaw it in cold water for a half-hour per pound of meat.
- 2). Remove the packaging and place the meat into the slow cooker. Open a packet of powdered onion soup mix and pour it into the pot. Add any vegetables or starches; potatoes and carrots pair well with the onion soup mix and beef.
- 3). Fill the pot to cover with water. Place the lid on the slow cooker and plug it into an outlet.
- 4). Read your slow cooker's instructions if you have any questions about its settings.
- 5). Turn the slow cooker on and set it to high, medium or low, depending on the length of time you plan to come back to check on it. Your London broil should reach 145 degrees Fahrenheit, which you can check with a meat thermometer. Generally, slow cookers have high and low settings. "Low" generally takes eight hours while "high" takes four hours.
- 6). Remove the meat and let it rest for 10 minutes on a cutting board. Slice and serve.
