Preparing the London Broil for Grilling

Before grilling, proper preparation of the London Broil is essential to maximize flavor and tenderness. Begin by trimming any excess fat from the meat, which helps prevent flare-ups on the grill and reduces grease drippings. Next, consider marinating the steak to both tenderize and infuse it with complementary flavors. A marinade typically includes acidic components such as vinegar, lemon juice, or wine, combined with oil, herbs, and spices.

When preparing the marinade, balance the ingredients to avoid overpowering the natural beef flavor. Common marinade components include:

  • Olive oil or vegetable oil to keep the meat moist
  • Acidic elements like balsamic vinegar or red wine for tenderizing
  • Aromatics such as garlic, onion, and fresh herbs (rosemary, thyme)
  • Seasonings including salt, black pepper, and crushed red pepper flakes

Allow the London Broil to marinate for at least 4 hours, or ideally overnight, in the refrigerator. This extended marination softens the muscle fibers and enhances juiciness.

After marinating, remove the steak from the fridge about 30 minutes prior to grilling to let it reach room temperature. This step promotes even cooking.

Grilling Techniques for Optimal Results

Grilling London Broil requires a balance of high heat for searing and moderate heat to finish cooking through. Preheat your grill to medium-high (around 400°F to 450°F). If using a gas grill, turn on all burners; for charcoal, ensure an even bed of hot coals.

Place the steak directly over the hottest part of the grill to sear. This creates a flavorful crust by triggering the Maillard reaction, which caramelizes the surface proteins and sugars.

Key grilling tips:

  • Sear the London Broil for about 4 to 6 minutes per side without moving it to develop grill marks.
  • After searing, move the steak to indirect heat (a cooler part of the grill) to finish cooking to the desired doneness.
  • Use a meat thermometer to monitor internal temperature precisely.

The following table outlines target internal temperatures and approximate grilling times for London Broil:

Doneness Internal Temperature (°F) Approximate Total Grill Time (minutes) Texture Description
Rare 120-125 8-10 Very red, cool center, very tender
Medium Rare 130-135 10-12 Warm red center, tender and juicy
Medium 140-145 12-14 Pink and firm, slightly less juicy
Medium Well 150-155 14-16 Light pink center, firm texture
Well Done 160+ 16-18 No pink, firm and less juicy

Avoid overcooking London Broil, as it is a lean cut that can become tough and dry if heated too long.

Resting and Slicing the London Broil

Once the steak reaches the desired internal temperature, remove it from the grill and place it on a cutting board. Resting the meat for 10 to 15 minutes is crucial. This allows the juices to redistribute throughout the muscle fibers, resulting in a moister, more flavorful eating experience.

When slicing, always cut against the grain of the meat. London Broil’s muscle fibers run lengthwise, so slicing perpendicular to these fibers shortens them and improves tenderness.

Tips for slicing:

  • Use a sharp carving knife to ensure clean cuts.
  • Slice the meat into thin strips, approximately ¼-inch thick.
  • Maintain consistent thickness for even texture in every bite.

Proper slicing enhances tenderness and presentation, making the grilled London Broil more enjoyable.

Serving Suggestions and Complementary Sides

London Broil pairs well with a variety of side dishes that balance its robust flavor and texture. Consider serving with:

  • Grilled or roasted vegetables like asparagus, bell peppers, or zucchini
  • Classic potato preparations such as mashed potatoes, roasted wedges, or baked potatoes
  • Fresh green salads with light vinaigrettes to add brightness
  • Grain-based sides like quinoa or wild rice for additional texture

Additionally, sauces such as chimichurri, garlic butter, or a red wine reduction complement the beef’s rich flavor without overpowering it.

When plating, arrange the sliced London Broil neatly and drizzle with a finishing sauce or pan juices. Garnish with fresh herbs to add visual appeal and aroma.

Preparing the London Broil for Grilling

Proper preparation is essential to maximize the tenderness and flavor of a London broil. This cut, typically a top round steak, benefits greatly from marinating and correct trimming.

Trimming: Begin by removing excess fat and any silver skin from the meat. This step helps improve texture and prevents flare-ups during grilling.

Marinating: Marinating not only infuses flavor but also tenderizes the relatively lean muscle fibers. Use a marinade with acidic components such as vinegar, lemon juice, or wine combined with oil and seasonings.

  • Acid Base: Vinegar, lemon juice, or wine to break down muscle fibers.
  • Oil: Olive or vegetable oil to retain moisture.
  • Seasonings: Garlic, herbs (rosemary, thyme), soy sauce, black pepper, and a touch of sugar or honey for caramelization.

Allow the London broil to marinate in the refrigerator for at least 4 hours, preferably overnight, sealed in a non-reactive container or zip-top bag. Remove the meat from the fridge 30 minutes before grilling to bring it to room temperature, ensuring more even cooking.

Grilling Technique for Optimal London Broil Results

Achieving a tender, flavorful London broil on the grill requires controlling heat and monitoring internal temperature carefully.

Step Action Details
Preheat Grill Medium-high direct heat Target a grill temperature around 400°F (204°C) to sear the steak effectively.
Oil Grill Grates Prevent sticking Use a high-smoke point oil on a folded paper towel to coat grates safely.
Initial Sear 4-5 minutes per side Place the London broil over direct heat to develop a caramelized crust.
Indirect Cooking Move to cooler zone Transfer to indirect heat to finish cooking without burning the exterior.
Internal Temperature Check Use a meat thermometer Remove at 130°F (54°C) for medium-rare or 140°F (60°C) for medium.

Maintain vigilance during grilling as London broil can become tough if overcooked. Use a reliable instant-read thermometer inserted into the thickest part of the meat to gauge doneness precisely.

Resting and Slicing the London Broil

Resting the meat after grilling is crucial to redistribute juices and ensure a moist, tender bite.

Once removed from the grill, tent the London broil loosely with aluminum foil and let it rest for 8-10 minutes. This allows the muscle fibers to relax and retain their juices rather than spilling out immediately when sliced.

Slicing Technique:

  • Identify the grain of the meat, which runs lengthwise along the steak.
  • Use a sharp carving knife to slice thinly against the grain. Cutting against the grain shortens muscle fibers, making each bite easier to chew.
  • Aim for slices approximately ¼ inch thick for optimal tenderness and presentation.

Serve immediately after slicing to enjoy the full flavor and texture benefits of the grilled London broil.

Professional Insights on How To Grill A London Broil

Michael Trent (Certified Butcher and Culinary Instructor). When grilling a London Broil, it is essential to marinate the meat for at least 4 to 6 hours to tenderize the typically tougher cut.
