- Cook Time: 50 minutes
- Total Time: 1 hour, 20 minutes + marinating time
- Yield: 4–6 servings 1x
Ingredients
- 2 pounds London Broil (top round or flank steak)
- 1/3 cup soy sauce
- 2 tablespoons olive oil
- 2 tablespoons balsamic vinegar
- 4 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried rosemary
- 1 teaspoon dried thyme
- 1/2 teaspoon freshly ground black pepper
- 1 1/2 pounds French fingerling potatoes, halved lengthwise
- 2 tablespoons olive oil
- 1 teaspoon sea salt
- 1/2 teaspoon freshly ground black pepper
- 2 sprigs of fresh rosemary
Instructions
- Marinate the London Broil (8 hours or overnight): In a mixing bowl, combine soy sauce, olive oil, balsamic vinegar, minced garlic, Worcestershire sauce, rosemary, thyme, and black pepper. Place the London Broil in a large resealable plastic bag and pour the marinade over the meat. Seal the bag, ensuring the meat is well-coated. Refrigerate for at least 8 hours, or overnight, turning the bag occasionally.
- Preheat the oven and prepare the potatoes (10 minutes): Preheat your oven to 400°F (200°C). Toss the halved fingerling potatoes with olive oil, sea salt, black pepper, and rosemary sprigs in a roasting pan.
- Roast the potatoes (40 minutes): Place the roasting pan in the oven and roast the potatoes for about 40 minutes, or until they are golden and tender, stirring halfway through cooking.
- Broil the London Broil (10 minutes for cooking, 10 minutes for resting): Remove the steak from the marinade and place it on a broiler pan. Preheat the broiler. Broil the steak about 4-5 inches from the heat source for about 5-7 minutes per side for medium-rare, or until desired doneness is reached. Remove from heat and let rest for 10 minutes before slicing against the grain.
- Serve (5 minutes): Slice the London Broil thinly against the grain. Serve with the roasted French fingerling potatoes. Garnish with additional rosemary sprigs if desired.
Notes
This dish is both easy to prepare and incredibly satisfying. Marinating the meat is crucial for achieving a tender and flavorful steak, so don’t skip this step.
The potatoes, with their crisp exterior and soft interior, complement the meat perfectly. For a complete meal, consider adding a green salad or steamed vegetables. Enjoy!
