How Long Should You Cook a London Broil?

By Robert Palmer

When it comes to cooking a London Broil, the question of how long to cook it is one that many people struggle with. The truth is, there is no one-size-fits-all answer to this question. The cooking time will depend on a variety of factors, including the size and thickness of the meat, as well as your preferred level of doneness.

Factors Affecting Cooking Time

The size and thickness of the London Broil will play a big role in determining how long it needs to be cooked. A thicker cut of meat will take longer to cook than a thinner one. Additionally, if you are cooking a larger piece of meat, it will take longer than a smaller one.

Another factor that can affect cooking time is whether or not the London Broil has been marinated. If you have marinated your meat, it may take longer to cook than if you had not.

Cooking Times Based on Thickness

If you are unsure about how long to cook your London Broil, the best way to determine cooking time is by using a meat thermometer. However, as a general guideline for an unmarinated London Broil:

  • For a 1 inch thick cut – Cook for 6-8 minutes on each side for medium-rare.
  • For a 1 1/2 inch thick cut – Cook for 8-10 minutes on each side for medium-rare.
  • For a 2 inch thick cut – Cook for 10-12 minutes on each side for medium-rare.

Using A Meat Thermometer

While these guidelines can be helpful, the most accurate way to determine when your London Broil is done is by using a meat thermometer. Here are some general temperature guidelines:

  • Medium-rare: 130-135°F
  • Medium: 140-145°F
  • Medium-well: 150-155°F
  • Well done: 160°F and above

Tips for Cooking London Broil

Here are some additional tips to keep in mind when cooking a London Broil:

  • Let the meat rest for at least 5 minutes after cooking to allow the juices to redistribute.
  • Cut against the grain of the meat to ensure tenderness.
  • If you are marinating your London Broil, be sure to use an acidic marinade that includes vinegar or lemon juice. This will help to break down the connective tissue in the meat and make it more tender.

In conclusion, how long you should cook a London Broil will depend on several factors, including thickness, size, and whether or not it has been marinated. Use a meat thermometer to ensure that your meat is cooked to your desired level of doneness, and be sure to let it rest before cutting. With these tips in mind, you can cook a delicious London Broil every time!
