- ¼ cup olive oil
- ¼ cup soy sauce low sodium
- 2 tablespoons Worcestershire sauce
- 1 tablespoon Dijon mustard
- 2 cloves garlic minced
- 1 teaspoon black pepper freshly ground
- ½ teaspoon salt or to taste
- 1 tablespoon dried rosemary chopped
- 1 tablespoon dried thyme chopped
- 1 tablespoon fresh parsley chopped
- 2 pounds London Broil steak such as flank steak or top round
In a small bowl, whisk together the olive oil, soy sauce, Worcestershire sauce, Dijon mustard, minced garlic, black pepper, salt, chopped rosemary, chopped thyme, and chopped parsley.
Place the London Broil steak in a large, shallow dish or a resealable plastic bag. Pour the marinade over the steak, making sure it's evenly coated. Cover the dish or seal the bag and marinate in the refrigerator for at least 2 hours, or overnight for best results.
When ready to cook, preheat the grill or broiler to high heat.
Remove the steak from the marinade and discard the remaining marinade.
Grill or broil the steak for 5-6 minutes per side, or until the internal temperature reaches 130°F for medium-rare or 140°F for medium, using a meat thermometer to check for doneness.
Transfer the steak to a cutting board and let it rest for 5-10 minutes before slicing against the grain into thin strips and serving.
- Cuts to use: Flank steak and top round are the classics. Sirloin or tri-tip also work well.
- Marinating time: At least 2 hours for flavor and tenderness, overnight if you can plan ahead.
- Cooking method: Keep the heat high so you get a nice sear on the outside while keeping the inside juicy.
- Resting is key: Let the steak sit for 5 to 10 minutes after cooking so the juices don’t run out.
- Slicing tip: Always slice thin against the grain to make each bite tender.
- Herb swaps: Fresh herbs are best, but dried will do. Just use less so they don’t overpower the marinade.
- Leftovers: Cold steak is perfect for sandwiches, wraps, or tossing on a salad the next day.
