Introduction

London broil, despite its name suggesting a specific cut of beef, primarily refers to a method of preparing and cooking a relatively inexpensive cut, typically flank steak or top round steak. The appeal of london broil lies in its ability to transform a potentially tough cut of meat into a tender and flavorful dish through proper marinating and a high-heat cooking method. The question of “how long to cook london broil” is central to achieving this delicious result, as the cooking time is crucial for ensuring a tender and juicy final product. Its popularity stems from its affordability, versatility, and potential for great flavor when cooked correctly.

Ingredients

The essential ingredients for a flavorful london broil include:

• London Broil (Flank or Top Round Steak): Approximately 1.5-2 pounds, about 1-inch thick.
• Marinade: (Choose one or combine elements)
  • Soy Sauce: 1/4 cup, provides umami and tenderizing properties.
  • Worcestershire Sauce: 2 tablespoons, adds depth of flavor.
  • Olive Oil: 2 tablespoons, helps distribute the marinade and prevents sticking.
  • Balsamic Vinegar: 2 tablespoons, adds acidity and sweetness.
  • Garlic: 2-3 cloves, minced, for aromatic flavor.
  • Dijon Mustard: 1 tablespoon, emulsifies the marinade and adds tang.
  • Fresh Herbs: 1 tablespoon chopped rosemary, thyme, or oregano for aroma.
  • Black Pepper: 1/2 teaspoon, freshly ground.
  • Salt: 1/2 teaspoon, adjust to taste after cooking.

Possible substitutions:

• Flank steak can be replaced with skirt steak, but cooking time should be adjusted due to its thinner nature.
• Coconut aminos can be used as a soy sauce substitute.
• Apple cider vinegar can be used as a balsamic vinegar substitute.

Preparation Steps

Proper preparation is vital for a tender and flavorful london broil.

1. Trim Excess Fat: Remove any large, thick pieces of fat from the surface of the steak.
2. Score the Surface (Optional): Lightly score the surface of the steak in a crosshatch pattern. This helps the marinade penetrate deeper and tenderizes the meat further. Be careful not to cut too deep.
3. Prepare the Marinade: In a bowl or resealable bag, combine all marinade ingredients. Whisk or shake well to ensure they are thoroughly mixed.
4. Marinate the Steak: Place the steak in the marinade, ensuring it is fully coated. Seal the bag or cover the bowl tightly. Marinate in the refrigerator for at least 2 hours, or ideally overnight (8-12 hours) for maximum flavor and tenderness.
5. Bring to Room Temperature: Remove the steak from the refrigerator about 30-60 minutes before cooking to allow it to come to room temperature. This promotes more even cooking.

Tip: Use a resealable plastic bag for marinating, making sure to squeeze out as much air as possible. Turn the bag occasionally to ensure even marinating.

Cooking Instructions

There are several methods for cooking london broil, each requiring slightly different timing. However, the key to “how long to cook london broil” is monitoring the internal temperature.

1. Grilling:
   • Preheat grill to high heat (450-500F).
   • Remove steak from marinade, discarding the marinade. Pat the steak dry with paper towels.
   • Grill for 4-6 minutes per side for medium-rare (130-135F), or 5-7 minutes per side for medium (135-145F).
   • Use a meat thermometer to ensure accurate internal temperature.
2. Broiling:
   • Position oven rack about 4-6 inches from the broiler. Preheat broiler to high.
   • Remove steak from marinade, discarding the marinade. Pat the steak dry with paper towels.
   • Place steak on a broiler pan.
   • Broil for 4-6 minutes per side for medium-rare (130-135F), or 5-7 minutes per side for medium (135-145F).
   • Use a meat thermometer to ensure accurate internal temperature.
3. Pan-Seared and Oven-Finished:
   • Preheat oven to 400F.
   • Heat a cast-iron skillet or oven-safe pan over high heat.
   • Remove steak from marinade, discarding the marinade. Pat the steak dry with paper towels.
   • Sear steak for 2-3 minutes per side until a good crust forms.
   • Transfer the pan to the preheated oven and cook for an additional 4-6 minutes for medium-rare (130-135F), or 5-7 minutes for medium (135-145F).
   • Use a meat thermometer to ensure accurate internal temperature.
4. Slow Cooker (less traditional, but possible):
   • Sear the steak in a hot skillet for a few minutes per side.
   • Place the seared steak in the slow cooker.
   • Add marinade or other liquids (beef broth, etc.)
   • Cook on low for 3-4 hours or until tender.
   • This method will result in a less traditional texture, more like a pot roast.

Important: Regardless of the cooking method, allow the steak to rest for at least 10 minutes after cooking before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.

Serving Suggestions

London broil is best served sliced thinly against the grain. This shortens the muscle fibers, making the steak easier to chew.

• Classic: Serve with roasted vegetables such as potatoes, carrots, and broccoli.
• Salad: Slice and serve over a bed of mixed greens with a vinaigrette dressing.
• Sandwiches: Use thinly sliced london broil for sandwiches or wraps with horseradish sauce or mustard.
• Tacos or Fajitas: Slice the steak and use it as a filling for tacos or fajitas with your favorite toppings.
• Sauces: Pair with a chimichurri sauce, barnaise sauce, or a red wine reduction.

Garnish: Fresh parsley or a sprinkle of sea salt can enhance the presentation.

Tips and Common Mistakes

• Don’t Overcook: Overcooking is the most common mistake when preparing london broil. Use a meat thermometer and aim for medium-rare to medium for optimal tenderness.
• Marinate Adequately: A sufficient marinating time is crucial for tenderizing and flavoring the steak.
• Pat Dry Before Cooking: Patting the steak dry before cooking ensures a good sear. Excess moisture will steam the steak instead of searing it.
• Rest the Steak: Resting the steak after cooking is essential for retaining juices and preventing it from drying out.
• Slice Against the Grain: Slicing against the grain is vital for breaking up the muscle fibers and making the steak easier to chew.
• Avoid Overcrowding the Pan: When pan-searing, avoid overcrowding the pan, as this will lower the temperature and prevent a good sear. Cook in batches if necessary.
• Use High Heat: For grilling or broiling, high heat is essential for quickly searing the outside of the steak while keeping the inside tender.
