To gas grill London Broil, start by searing the meat over high, direct heat for a few minutes per side until a nice crust forms. Then, move it to a cooler, indirect heat zone to finish cooking until it reaches your preferred internal temperature.
For the most tender and flavorful results, aim for a medium-rare doneness, which is usually around 130-135°F, allowing for carryover cooking after resting.
- Marinate your London Broil for at least a few hours to boost flavor and tenderness.
- Preheat your gas grill to a high setting for searing, then adjust for two-zone cooking.
- Sear the meat quickly on both sides over direct heat to create a delicious crust.
- Move the London Broil to indirect heat, closing the lid, until it reaches desired internal temperature.
- Always use a meat thermometer and let the meat rest for 10-15 minutes before slicing against the grain.
How To Gas Grill London Broil?
Gas grilling London Broil involves a simple yet effective two-zone cooking method: sear it hot and fast, then finish it slow over indirect heat. This approach ensures a beautiful crust and a tender, juicy interior every time.
Understanding Your London Broil Cut
When you ask for “London Broil” at the butcher, you might actually get one of a few different cuts. Most often, it refers to a thick cut of flank steak or top round steak.
These cuts are known for being lean and muscular. That means they need some careful handling to become tender, which is where proper grilling techniques and marination really come in handy.
Is it Really a Specific Cut?
Many experts say London Broil is more a preparation method than a specific cut of beef. It’s all about how you cook and slice these tougher, leaner steaks. The goal is always maximum tenderness and flavor.
Why Choose Gas Grilling for London Broil?
Gas grills offer fantastic control, making them ideal for cooking London Broil. You can easily create distinct hot and cool zones, which is absolutely vital for this cut. It’s about precision and convenience.
The Power of Direct and Indirect Heat
With a gas grill, you can turn burners on and off to create a “two-zone” setup. One side gets scorching hot for searing, while the other side stays cooler for gentle, even cooking. This method prevents overcooking the outside before the inside is done (USDA).
Essential Prep: Marinating for Tenderness
Marination is your secret weapon for London Broil. Because these cuts are lean, they can dry out or be tough without a good marinade. It adds flavor and helps break down some muscle fibers.
Your Marinade Checklist
A good marinade usually includes a few key components. Think of it as a flavor bath for your meat.
- An acid: vinegar, citrus juice, or wine helps tenderize.
- Oil: olive or vegetable oil helps carry flavors and keep moisture.
- Seasonings: garlic, onion, herbs like rosemary or thyme, salt, and pepper.
- Flavor boosters: soy sauce, Worcestershire sauce, or Dijon mustard.
How Long Should You Marinate?
We found that marinating London Broil for at least 2 hours is good, but 4-8 hours is ideal for best results. Many chefs recommend not going beyond 12 hours, as the acid can start to make the meat mushy.
Getting Your Gas Grill Ready
Preparation isn’t just about the meat; it’s about your grill too. A clean, hot grill is essential for preventing sticking and getting those perfect grill marks.
Preheating for Success
Always preheat your gas grill. Turn all burners to high, close the lid, and let it heat up for 10-15 minutes. This gets the grates screaming hot for searing. After preheating, you will adjust for your two-zone setup.
The Grilling Process: Sear, Cook, Conquer
This is where the magic happens! We’ll use the two-zone method to get the best out of your London Broil. It’s a method that works for many cuts, but especially well here.
Mastering the Two-Zone Cooking Method
First, set up your grill. Turn one side to high heat (direct zone) and the other side to low or off (indirect zone). Sear your London Broil for 3-4 minutes per side over direct heat until a rich brown crust forms.
After searing, move the meat to the indirect side. Close the lid and let it cook slowly, flipping occasionally, until it reaches your desired internal temperature. This gentle finish keeps it juicy.
Grilling Times and Temperatures
These are general guidelines. Always use a meat thermometer for accuracy (USDA).
| Doneness Level | Internal Temperature | Approximate Grilling Time (Indirect) |
|---|---|---|
| Rare | 125-130°F | 8-12 minutes |
| Medium-Rare | 130-135°F | 10-15 minutes |
| Medium | 135-140°F | 12-18 minutes |
| Medium-Well | 140-145°F | 15-20 minutes |
Doneness: Hitting Your Sweet Spot
For London Broil, most grill masters agree that medium-rare to medium is ideal. Cooking it past medium-well can make it tough and dry. Remember, this isn’t a cut meant for well-done perfection.
Why a Meat Thermometer is Your Best Friend
You might think you can tell doneness by touch, but a meat thermometer removes all guesswork. Insert it into the thickest part of the meat, avoiding any bone. It’s the most reliable way to ensure perfect results (FoodSafety.gov).
Keep in mind, the meat’s temperature will rise a few degrees after you remove it from the grill. This is called “carryover cooking.” So, pull it off a few degrees below your target.
The Critical Rest and Slice
These last two steps are often overlooked, but they are incredibly important. Skipping them can turn a perfectly cooked steak into a disappointment. Don’t rush this part of the process.
Slicing Against the Grain: A Game Changer
After grilling, place the London Broil on a cutting board and loosely tent it with foil. Let it rest for 10-15 minutes. This allows the juices to redistribute throughout the meat, keeping it moist. Many research findings confirm this.
When you’re ready to slice, find the “grain” of the meat – these are the long muscle fibers. You want to slice perpendicular to these fibers, into thin pieces. Slicing against the grain shortens the fibers, making each bite much more tender and easier to chew.
Common Mistakes to Avoid
Even experienced grillers can sometimes make small errors. Avoid these common pitfalls to ensure your London Broil is always a success.
- Not marinating long enough, or at all.
- Forgetting to preheat the grill.
- Overcooking past medium-rare/medium.
- Not resting the meat before slicing.
- Slicing with the grain instead of against it.
Conclusion
Grilling London Broil on a gas grill is a straightforward path to a delicious meal. By understanding the cut, giving it a good marinade, using two-zone heat, and remembering to rest and slice correctly, you’ll achieve fantastic results. Enjoy your perfectly grilled London Broil!
Can I grill London Broil without marinating?
While you can, marinating is highly recommended for London Broil. It significantly enhances flavor and helps tenderize the lean cut, preventing it from becoming tough or dry during cooking.
What if my gas grill doesn’t have multiple burners for two-zone cooking?
If your grill has only one burner, you might sear on high for a short time, then turn the heat to low, closing the lid, to finish cooking. It’s less ideal, but still works. You can also use a grill basket to elevate the meat slightly from the heat.
How do I know when to flip the London Broil on the grill?
For searing, flip when you see a nice, brown crust form, usually 3-4 minutes per side. When cooking over indirect heat, you can flip every 5-7 minutes to ensure even cooking.
My London Broil always seems tough. What am I doing wrong?
Toughness usually comes from overcooking, not marinating, or slicing with the grain. Ensure you cook to medium-rare or medium, marinate for several hours, and always slice thinly against the meat’s natural fibers.
Can I add wood chips to my gas grill for smoke flavor with London Broil?
Absolutely! Place a foil packet or a smoker box filled with pre-soaked wood chips (like hickory or oak) over the direct heat zone of your gas grill. This will add a wonderful smoky essence to your London Broil.
