London broil is not a tender cut of steak, but it is affordable and if you marinate it and cook it right, it can be delicious. This cut of beef is perfect for the grill or broiler (hence the name) and when it is on sale its fairly inexpensive to feed a family of four. While you will see London broil labeled as such in the store, it actually isn't a specific cut of meat, it is a way of cooking meat. The cut is generally top round steak. So if you don't see London Broil look for top round steak or you can get flank steak.
I have put together a very simple, yet flavor deep marinade for you to try. It will give it great steakhouse flavor, while using very common ingredients. Feel free to mix up the marinade though to suite your mood. I love a good southwest marinade on this cut as well, then you can serve it with fresh mango salsa. If you do not want to purchase the ingredients to make your own marinade, feel free to buy an already made one at the store. When they are on sale they can really be a great deal as well.
1 ½ - 2 lb London Broil 5 Tbsp Steak Sauce 1 Tbsp Balsamic vinegar 1 Tbsp Olive Oil 1 ½ tsp Garlic Powder 1 ½ tsp Onion Powder ½ tsp Chili Powder 1 ½ lb Green Beans (ends trimmed) ½ pint Grape (cherry) Tomatoes ½ Onion roughly chopped 2 Garlic Cloves Chopped 3 Tbsp Grain or Dijon Mustard 1 Tbsp Olive Oil Salt Pepper
Put steak sauce, balsamic vinegar, 1 Tbsp olive oil, garlic powder, onion powder and chili powder in a large ziplock bag. Place London Broil inside bag and coat with marinade. Place in fridge and let sit for at least 4 hours up to overnight. The longer it can marinate the better.
Pull the London broil out of the fridge a 1/2 hour before cooking and let it come to room temperature.
Preheat your oven to 400 degrees and heat grill to medium-high heat.
Place tomatoes and green beans in a bowl with the onion, garlic, mustard, and 1 Tbsp olive oil. Add a couple dashes of salt and pepper. Mix around to coat everything.
Place green bean mixture on a baking sheet and roast for about 15-20 min. Stir about every 10 min. The cooking time depends on how well done you like your green beans.
Part way into the green beans cooking process place London broil on grill. Depending on the thickness it will take between 5 and 8 min a side for medium rare. If you want to check by temp, the thermometer should read between 125-130 degrees.
Once meat is done take off grill and let sit for 5-10 min before slicing. Meat will continue to cook while it sits so don’t overcook meat on the grill. Slice the meat into thin strips against the grain serve alongside green beans.
