Grilled London Broil is a delicious way to enjoy the outdoors this summer. London Broil steak is flavorful and guaranteed tender. Cooked over high heat for lovely sear marks with a juicy center. This post includes an easy marinade recipe plus lots of tips to make you a grilling pro.

London Broil doesn’t actually refer to the cut of the meat, instead the name comes from the cooking method. Similar to broiling, the steak is cooked over a high heat grill that cooks from the outside, to know how to grill a steak like a pro check my How to Grill Steak recipe.

On that note, you can also broil the steak in an oven if you don’t have access to a grill, which I’ll cover later.

The classic way to cook London Broil is over very hot grates on a grill. The steak places on the grill at an angle, then rotated midway to create a square pattern of sear marks. Not only does it taste amazing, it looks amazing.

Type of Steak to Use for London Broil

London Broil is not the actual cut of steak, just the cooking method. Look for flank or top round steak in the meat section of your grocery store.

The main thing is the steak should be thin, no more than an inch thick. This is because of the high-heat method of cooking.

Do You Need to Marinade London Broil?

Traditionally a balsamic vinegar-based marinade is used to flavor and tenderize the meat. The acids in vinegar helps to break down the meat proteins. You could skip this and just use dry seasonings and spices, such as a steak seasoning.

Simple London Broil Marinade

If you prefer to marinate, here’s a simple list of ingredients you’ll need. It’s a mixture of herbs, acids and umami elements to enhance the flavors and texture of the meat.

• Minced garlic cloves
• Balsamic vinegar
• Dijon mustard
• Worcestershire sauce
• Died Italian seasonings
• Salt and pepper
• Crushed red hot red pepper flakes

If you don’t have time to marinate a simple mixture of salt, pepper, and additional spices and herbs such as garlic powder and Italian seasoning works well to flavor the meat.

You can also use a dry steak seasoning rub instead, which contains many of these ingredients as well. Sprinkle liberally on both sides of the meat and let sit at least 30 minutes to infuse flavors.

How Long to Marinade London Broil

Ideally, you want to marinate for at least one hour to infuse flavors into the meat. Marinating longer, 8 hours or overnight, will help to tenderize the meat.

Tips for Grilled London Broil

• Use quality meat: Look for flank or top round steak, ideally organic or grass-fed.
• Thickness affects cooking: Since high heat is used, the steak should be less than 1-inch thick.
• Marinate to infuse flavors into the meat and improve texture: A simple marinade that includes balsamic vinegar helps to enhance flavors of the meat and create a juicy texture.
• Bring meat to room temperature: Let sit at least 30 minutes before cooking. This creates more even cooking throughout while still getting nice sear marks
• Use high heat on the grill: Preheat grill to medium-high or about 500° F. This sears the outside quickly to create iconic sear marks.
• Add meat at an angle and rotate: Place meat at a 45 ° angle on the grill. Cook a few minutes until seared, then rotate 90° to create a cross-hatch pattern.
• Rest 5-10 minutes before cutting: This allows moisture to be absorbed back into the meat proteins and reduces liquid loss.
• Cut across the grain: This helps to improve the texture when eating the steak.

How to Grill London Broil

• Marinate or season the steak ahead of time.
• Remove steak from the fridge and bring it to room temperature, about 30-45 minutes, before cooking.
• Preheat a gas grill to medium-high heat, about 500° F. Place steaks on the grill at a 45° to the grates, close lid, and grill 2-3 minutes until bottoms are seared. Rotate 90° and continue to grill 2-3 minutes to create cross-hatch grill marks.
• Rotate and repeat for the other side, or until internal temp of 135° F for rare to medium-rare.
• Remove from grill and let rest 5-10 minutes. Cut steaks across the grain, plate the steak with mashed potato then serve.

Internal Temps for BBQ London Broil

The following are internal temps based on your desired doneness: Rare: 135 to 140°, Medium Rare: 140°, Medium: 150 to 155°, Well Done: 165°.

140° is for best for tender and juicy steaks.

London Broil in the Oven

If you don’t have access to the grill or weather isn’t ideal, you can make London Broil in the oven.

Marinate or season as directed then place on a foil-lined baking sheet in the middle of an oven. Broil on high for about 6 minutes, rotate a broil the other side 5-7 minutes more to reach the desired doneness.

This London Broil Steak also pairs well with a variety of sides like Roasted Sweet Potato and Zucchini Salad.
