These steps help break down the muscle fibers and infuse the meat with flavor. Whether you use a grill, broiler, or pan, mastering these techniques will make your London broil wonderfully tender and delicious every time.
This guide covers everything from marinade recipes to ideal cooking temperatures and resting methods. Follow along to enjoy a perfectly cooked London broil that rivals your favorite steakhouse – no special equipment required.
Choosing The Right Cut For London Broil
Though London broil refers to a cooking method, the choice of beef cut significantly affects the final result. The most common choices are flank steak and top round steak. Flank steak is lean with long muscle fibers, which makes it flavorful but prone to toughness if overcooked.
Top round, from the rear leg, is lean and moderately tender but generally thicker than flank steak. Both require proper marinating and slicing against the grain to maximize tenderness. Another acceptable option is skirt steak, which shares similar characteristics but cooks slightly faster.
Comparison Of Common Cuts Used For London Broil
| Cut | Flavor | Texture |
|---|---|---|
| Flank Steak | Beefy, rich | Lean, fibrous |
| Top Round | Moderate beef flavor | Lean, slightly tougher |
| Skirt Steak | Intensely beefy | Thin, tender with fat |
Preparing Your London Broil For Cooking
Marinating is arguably the most important step for tenderizing London broil. An acidic marinade helps break down tough muscle fibers and adds great flavor. Common acids include balsamic vinegar, lemon juice, or red wine. Adding aromatics like garlic, soy sauce, and olive oil enrich the taste and improve texture.
For the best results, marinate your meat for at least 4 hours, or preferably overnight. Use a resealable bag or non-reactive container, and keep it refrigerated during the process. Remove the meat and pat it dry before cooking; excess marinade can cause steaming rather than searing.
Simple London Broil Marinade Recipe
- ½ cup olive oil
- ¼ cup soy sauce
- 2 tbsp Worcestershire sauce
- 2 tbsp lemon juice or balsamic vinegar
- 3 cloves garlic, minced
- 1 tsp black pepper
- 1 tsp brown sugar (optional)
Combine all ingredients in a bowl or bag, add the steak, and refrigerate.
Cooking Techniques For London Broil
London broil is traditionally cooked under a broiler or on a grill, both methods achieving a high heat sear that locks in juiciness. Pan-searing followed by oven roasting is another excellent method. The key is intense heat and careful timing to keep the meat medium-rare to medium.
Since this cut is prone to toughness when overcooked, aim for an internal temperature no higher than 135°F (medium rare) to 145°F (medium). Using a meat thermometer ensures accuracy and prevents drying out the meat.
Step-By-Step Grilling London Broil
- Preheat grill to high heat (about 450–500°F).
- Remove steak from marinade and pat dry.
- Lightly oil the grill grates to prevent sticking.
- Grill the steak for about 4–6 minutes per side.
- Check the internal temperature early (use a probe thermometer).
- Rest the steak loosely tented with foil for 10 minutes before slicing.
Broiling Method
- Place the oven rack about 4–6 inches below the broiler element.
- Preheat broiler to high.
- Use a broiler pan with a rack to catch drippings.
- Broil about 4–5 minutes per side, watching closely.
- Check temperature to avoid overcooking.
Pan-Searing And Oven Finishing
- Heat a heavy skillet (cast iron preferred) over medium-high heat.
- Add a tablespoon of oil and sear steak for 3–4 minutes per side until browned.
- Transfer skillet to a preheated 400°F oven for 5–7 minutes.
- Check internal temperature, then remove and rest meat.
Slicing And Serving London Broil
The final and most crucial step is slicing. Always slice London broil thinly against the grain. This breaks up muscle fibers and makes each bite easy to chew. Cutting with the grain results in a stringy, tough texture.
Serving suggestions include topping with sautéed mushrooms, chimichurri sauce, or a fresh herb salad. London broil pairs well with hearty sides like roasted vegetables, mashed potatoes, or a crisp green salad.
Tips To Ensure Perfect London Broil Every Time
- Keep the marinade acidic to help tenderize the meat.
- Don’t skip the resting period after cooking, as it allows juices to redistribute.
- Use an instant-read thermometer for precise cooking.
- Slice very thinly against the grain for maximum tenderness.
- Cook to medium-rare or medium to avoid toughness.
- Let steak come to room temperature before cooking (about 30 minutes).
