Selecting the Best Cut for London Broil
When selecting the best cut for London Broil, choose a lean, long, flat piece of beef from the cow’s abdominal muscles. Flank steak is the most traditional and recommended cut of beef for London Broil because of its flavor and tenderness when properly marinated.
You can also consider top round steak or top sirloin roast, but flank steak remains the preferred choice. Look for a cut with good marbling and a fresh, bright red color to guarantee better flavor and tenderness.
Aim for a thickness of about 1 to 1.5 inches, which works best for even cooking. Proper selection of the cut directly influences how your marinade penetrates and how well the meat responds to your grill temperature during cooking.
Preparing Your London Broil for Grilling
Now that you’ve chosen the right cut, it’s time to prepare your London Broil for the grill. Start by pounding the meat to an even thickness and marinating it for at least an hour to boost flavor and tenderness.
Don’t forget to bring the meat to room temperature before grilling for the best results. This step really helps it cook more evenly, trust me!
Selecting the Right Cut
How do you choose the perfect cut for a delicious London Broil? Start by selecting flank steak, the traditional and preferred cut of meat for its flavor and tenderness. Flank steak is a long, flat cut from the cow’s abdominal muscles, offering a great balance of texture and taste.
When choosing your cut, look for one about 1 to 1.5 inches thick to ensure even cooking and proper searing. Pay attention to the quality: pick meat with a deep red color, minimal marbling, and no brown patches or discoloration.
Also, select a piece that’s uniform in thickness, which helps it cook consistently on the grill. While top round can work, flank steak remains the best choice for grilling success.
Marinating Techniques
Because marinating releases deeper flavors and tenderizes the meat, you should let your London Broil soak in a well-balanced marinade for at least two hours. Though, honestly, up to 24 hours yields the best results.
To marinate effectively, use these marinating techniques for peak flavor infusion:
- Choose a marinade recipe with key marinade ingredients like olive oil, vinegar, garlic, soy sauce, and herbs.
- Place the meat in a resealable plastic bag or shallow dish to coat it evenly.

Slicing London Broil to Maximize Tenderness
After letting your London Broil rest, the next step is slicing it properly to enhance tenderness. To maximize tenderness, always slice against the grain, which shortens muscle fibers for easier chewing.
Use a sharp knife to cut cleanly and avoid tearing the meat. Cutting at a 45-degree angle creates thinner, more tender slices. Aim for ⅛ to ¼ inch thickness to balance tenderness and flavor perfectly.
| Step | Technique | Reason |
|---|---|---|
| Rest | 5-10 minutes | Juices redistribute |
| Slice | Against the grain | Shortens muscle fibers |
| Angle | 45 degrees | Creates tender, easy-to-chew cut |
| Thickness | ⅛ to ¼ inch slices | Ideal tenderness and flavor |
