Grilled Marinated London Broil is a show stopper.  A simple marinade of red wine, garlic, olive oil turns an inexpensive cut of meat into a steakhouse worthy meal.  

If you’re looking to turn an inexpensive cut of meat into a showstopper of a meal,  then today’s recipe is for you. 

Now, I love a good Ribeye, Top Sirloin or NY Steak but they can get really expensive. When the craving hits and  I’m looking to save money, using london broil is a great alternative. They are often less expensive and larger so they can feed a crowd. 

You just need one simple trick to turn this tougher cut of meat into a flavorful, tender steak.  

First things first: 

What cut of meat is London Broil?

Now technically a london broil is not a cut of meat but a cooking method, designed to make the best out of lean, tough cuts of meat. This can get somewhat confusing because butchers at grocery stores often put the “london broil” label on several different cuts of meat including flank steak, shoulder and round. For this recipe I used top round.

How do you make London Broil tender?

One word: Marinade. The cuts of beef used to make London broil, lend themselves really well to marinades. The marinade tenderizes the meat and enhances the flavor.

DES’ TIP: You can marinate too long resulting in an off texture to the meat, to avoid this don’t marinate the steak longer than 1 – 2 days. I usually do overnight.

For this London broil recipe, I mixed a simple marinade of fresh garlic, olive oil, Worcestershire sauce, red wine and salt and pepper.

In addition to the marinade, leaner cuts of beef are also more tender when they are cooked medium-rare to medium. If you were to cook them medium or well done, they will become very tough.

Finally, make sure to cut the steak against the grain. This will also help keep it tender.

Step by Step Instructions:

• STEP 1: Whisk together ingredients for the marinade.
• STEP 2: Use a sharp knife to cut slits all over the steak. Pour the marinade over the steak. Cover and refrigerate 6 – 8 hours overnight.
• STEP 3: Remove steak about 1 hour before you’d like to cook it so it has a chance to come up to room temperature. Discard the marinade. Pat the steak dry.
• STEP #4: Heat your outdoor grill on medium, lightly oil grate. Grill 9 – 10 minutes on each side for medium rare or until desired doneness. Depending on the thickness of your steak, mine was about 1 1/2 inches, it may take longer to cook.

If you’re looking for side dishes to serve alongside, I love serving this steak with Air Fryer Hasselback Potatoes or Air Fryer French Fries and a Caesar salad made with homemade caesar dressing.
