This is a good, old English-style London broil recipe that has lots of flavors and will produce a tender cut of steak. Marinating is key for a tender and delicious finished product. 

Ingredients

  • 1 1/2 to 2 pounds/680 to 900 kg. flank steak
  • 1/2 cup/120 mL butter
  • 1/4 cup/60 mL beef broth
  • 1/4 cup/60 mL dry red wine
  • 2 tablespoons/30 mL olive oil
  • 2 tablespoons/30 mL minced fresh parsley
  • 2 cloves garlic (minced)
  • 2 tablespoon/30 mL red wine vinegar
  • 1 tablespoon/15 mL minced scallion tops
  • 1 teaspoon/5 mL Worcestershire sauce
  • 1 1/2 teaspoons/7.5 mL sea salt

Steps to Make It

  1. Cut 1-inch diamonds about 1/8 inch deep in both sides of the flank steak.

  2. Combine crushed garlic, olive oil, red wine vinegar salt, and black pepper in a small non-metallic bowl.  

  3. Place steak in a resealable plastic bag.  

  4. Pour marinade over steak, making sure all surfaces are covered.  

  5. Seal bag, letting out any excess air and place into the refrigerator for 6 to 12 hours.

Tips

  • To prepare sauce: Melt butter and mix together with beef broth, dry red wine, Worcestershire sauce, parsley, and scallions. Keep warm until ready to serve.
  • Preheat grill for high heat. Remove steak from bag and discard marinade. Grill steak about 5 to 6 minutes on each side. Once cooked to desired doneness, remove steak from grill, let rest for 8 to 10 minutes. Cut into thin strips and serve with sauce on top.
