Many of you may remember last year, I had the opportunity to interview the winner of the Cowboy Charcoal 2016 Fire & Ice Championship, Jayna Todisco. She battled it out all year against other lady-led BBQ competition teams and came out on top as the big winner at the World Food Championships. This year, the battle is renewed with even more female forces threw their hats into the ring. These women tracked their points in KCBS certified competitions all year to vie for a chance to win a Golden Ticket to participate in the World Food Championships and earn the Fire & Ice title. The contest ends on October 30th, 2017 and then the winners will be notified and start planning their trip to Orange Beach, Alabama!

You can follow along too by watching for new posts on Facebook or Instagram as the competition progresses!

How to Grill London Broil

Now onto the recipe! I love a simple steak marinade that doesn’t take away from any of the naturally great beef flavors. I tend to reserve marinades for cuts like top round steaks or flank steaks that do great over a hot and fast fire, or “London Broil.” You see, London Broil is actually a cooking method, although often labeled in grocery stores as a cut of meat. Any cut that you can broil or grill over high heat and slice against the grain work well for London Broil and those cuts often benefit from a great marinade. This one uses olive oil for tenderizing and flavor, as well as red wine vinegar, Worcestershire for some richness, lots of garlic, red pepper flakes, salt, pepper, and fresh rosemary. Like I said, not too strong to take away from the flavors of meat on a grill, but just enough to complement everything that is going on. I hope you love this one!

Simple Grilled London Broil Marinade

This London Broil Marinade is super simple and perfect for the grill! Loads of garlic, red wine vinegar, and Worcestershire round out the marinade for a steak that is both tender and flavorful.
Prep Time10 mins
Cook Time15 mins
Total Time2 hrs 25 mins
Course: Main Dish
Servings: 4 people


  • 1 1 1/2-2 pound top round or flank steak
  • 3/4 cup olive oil
  • 3/4 cup packed brown sugar
  • 1/4 cup red wine vinegar
  • 8 cloves garlic minced
  • 1 1/2 Tablespoons Worcestershire sauce
  • 1 Tablespoon salt
  • 2 teaspoons black pepper
  • 2 teaspoons red pepper flakes
  • 2 sprigs fresh rosemary


  • Combine all of the marinade ingredients in a zip top gallon bag or a large lidded container. Submerge the steak in the marinade and press all of the air out of the bag. Massage and turn the bag over several times to ensure the meat is coated. Marinate for 2 hours at least, or overnight for better flavor.

  • Light your charcoal, allow it to catch and start to ash over and then dump it into your grill or preheat your grill to 450 degrees F. Sear the steak for 4-6 minutes per side (depending on thickness) or until the internal temperature reads 135 degrees F for medium rare.

  • Remove the steaks from the grill and allow to rest for 10 minutes before slicing against the grain and serving. I like to sprinkle with a little more coarse salt and some fresh cracked black pepper right before serving.


I actually managed to fit two steaks into the marinade, so if you're cooking for more people you don't need to stress about doubling the marinade too.

  1. Best London Broil I’ve ever had! Juicy, flavorful and oh so tender! I marinated for about 3 hours before putting on the grill. Will definitely do this again.

  2. Amazing! I didn’t have red wine vinegar, tho, so I used a red wine. My whole family loved it so much! Great flavour, and wonderful texture. My fresh chips paired in comparison! Ha ha. I will make this again and pass on to friends and family. Sláinte!

    1. Plan on about 20-30 mins per pound for these. Use a thermometer to determine when it’s finished! London broil is at its best around medium rare, 140F.

  3. Did it exactly step for step and I am the hero of the bbq. This recipe, and the tips before it, were extremely helpful. Thank you very much for this post.

  4. I’m not no novice on a Weber but followed the recipe and the best London broil I’ve done my hobby is smoking and grilling meat and this was sweet used hickory and apple chunks so awesome

  5. Do I need red wine vinegar to marinate–or can I just use Teriyaki sauce, salt, pepper and garlic? Please let me know! Thanks.
