Ever wonder why some London broil recipes turn out tough and chewy while others are melt-in-your-mouth tender? I used to be terrified of grilling this cut until I discovered this foolproof London broil recipe. Now my family requests this classic American steakhouse favorite every weekend, and I’m pretty sure my brother-in-law thinks I went to culinary school (if only he knew how many times I turned this into shoe leather before getting it right).
Here’s the Thing About This Recipe
The secret to authentic London broil isn’t some fancy technique—it’s all about the marinade and knowing when to stop cooking. What makes this recipe work is the perfect balance of savory soy sauce and Worcestershire that breaks down those tough muscle fibers while adding incredible depth of flavor. I learned the hard way that London broil goes from perfect to overcooked in about 90 seconds, so keeping a close eye on it is crucial. It’s honestly that simple—marinate well, cook hot and fast, slice thin against the grain, and you’ll have tender, flavorful meat every single time.
What You’ll Need (And My Shopping Tips)
Good London broil steak is worth hunting down at a butcher shop that actually knows their cuts. Don’t cheap out on some mystery “marinating steak” from the discount bin—I learned this after three disappointing dinners. Look for top round or flank steak labeled as London broil, about 1.5 to 2 inches thick (happens more than I’d like to admit, but thickness really matters here).
For the marinade, I always grab low-sodium soy sauce because regular stuff can make this way too salty. Fresh garlic beats jarred every time—trust me on this one. The Worcestershire sauce adds that umami punch that makes people ask “what’s in this?” Good olive oil for brushing is essential since it helps create that beautiful char. I always grab an extra lemon because someone inevitably wants a squeeze of fresh citrus over their slices.
Let’s Make This Together
Start by whisking together your marinade in a bowl—soy sauce, Worcestershire, minced garlic, onion powder, black pepper, and paprika. Here’s where I used to mess up: I’d barely mix it and wonder why the flavors were uneven. Give it a good 30-second whisk until everything’s completely combined.
Drop that London broil into a shallow dish (I use a 9×13 baking dish) and pour the marinade right over it, making sure every inch gets coated. Flip it once or twice, then cover tightly with plastic wrap and stick it in the fridge. Now for the fun part—waiting. At least 4 hours, but honestly, overnight is when the magic happens. Those acidic ingredients need time to work their way into the meat.
When you’re ready to cook, crank your grill to medium-high heat (around 450°F if you’ve got a thermometer). Here’s my secret: pull that steak out of the marinade and pat it completely dry with paper towels until it practically squeaks. Wet meat steams instead of sears, and we want those gorgeous grill marks. Brush both sides generously with olive oil—this is your insurance policy against sticking.
Slide it onto the grill and resist the urge to move it around. Give it 5-7 minutes per side for medium-rare, just like traditional steakhouse London broil should be cooked. Don’t stress about this part—use an instant-read thermometer if you’re nervous (125°F for medium-rare). I learned this trick from my neighbor who worked in restaurants: let it rest for a full 10 minutes before slicing. This isn’t optional—cutting too early and all those juices run right onto your cutting board instead of staying in the meat.
The most important step? Slice thin against the grain. See those muscle fibers running one direction? Cut perpendicular to them. This turns potentially chewy meat into tender bites.

If This Happens, Don’t Panic
Steak turned out tough? You probably cooked it past medium or didn’t slice against the grain—both mistakes I’ve made more times than I’ll admit. In reality, I’ve learned to pull London broil off the grill when it feels slightly firmer than raw but still has good give when you press it. If this happens (and it will), slice it extra thin and serve with a flavorful sauce to add moisture back.
Marinade tastes too salty? Next time use low-sodium soy sauce and cut back by a tablespoon. This is totally fixable mid-marinate—just add a tablespoon of water to dilute it. I always check early now because every soy sauce brand has different sodium levels.
Meat sticking to the grill? Your grates weren’t hot enough or you didn’t oil the steak well. Don’t panic, just use a sturdy spatula to gently release it. Clean, oiled grates are your best friend here.
When I’m Feeling Creative
Garlic Lover’s London Broil: Double the garlic and add a tablespoon of fresh rosemary to the marinade. Around the holidays, I’ll make this version and it disappears even faster.
Asian-Style London Broil: Swap half the soy sauce for teriyaki sauce and add a teaspoon of fresh grated ginger. This one’s my go-to when I’m feeling fancy.
Spicy Pepper London Broil: Add a tablespoon of crushed red pepper flakes and some cayenne to the marinade. My teenager requests this version constantly.
Balsamic London Broil: Replace Worcestershire with balsamic vinegar for a tangy twist that works great in summer salads.
What Makes This Recipe Special
London broil isn’t actually a cut of meat—it’s a cooking method that originated in American steakhouses during the mid-20th century. The technique involves marinating a tougher cut (traditionally flank or top round), cooking it quickly at high heat, and slicing it thin against the grain. What sets this version apart from others is the balanced marinade that tenderizes without overpowering the natural beef flavor, plus the focus on proper resting and slicing technique that transforms an economical cut into something that tastes way more expensive than it is.
Things People Ask Me About This Recipe
Can I make this London broil recipe ahead of time?
Absolutely! The marinating part actually works better when done the night before. Just don’t slice it until you’re ready to serve—once it’s cut, it dries out faster in the fridge.
What if I don’t have a grill for this grilled London broil?
Your broiler works great! Set it to high, place the oven rack 4-5 inches from the heating element, and cook for the same timing. I’ve done this plenty of times when it’s pouring rain outside.
How spicy is this classic London broil marinade?
It’s not spicy at all—just savory and slightly peppery. The black pepper and paprika add flavor without heat, making it perfect for everyone at the table.
Can I freeze this marinated London broil?
Yes! Actually, I’ll freeze the raw steak right in the marinade in a freezer bag. Thaw it in the fridge overnight and it’s been marinating the whole time—genius move for meal prep.
Is this London broil recipe beginner-friendly?
Totally. If you can mix ingredients in a bowl and flip meat on a grill, you’ve got this. The hardest part is waiting for it to marinate and rest.
What’s the best way to store leftover grilled London broil?
Wrap sliced leftovers tightly in foil or an airtight container and refrigerate for up to 3 days. They’re amazing cold in sandwiches or reheated gently in a skillet with a splash of beef broth.

Perfectly marinated and grilled London broil that’s tender, juicy, and packed with savory flavor—this classic steakhouse recipe makes an affordable cut taste absolutely incredible.
Prep Time: 10 minutes (plus 4 hours marinating) | Cook Time: 15 minutes | Total Time: 4 hours 25 minutes | Servings: 6
Ingredients
- 2 lbs London broil steak (top round or flank steak, about 1.5–2 inches thick)
- 1/4 cup soy sauce (low-sodium works great)
- 2 tbsp Worcestershire sauce
- 2 cloves garlic, minced (fresh is worth it here)
- 1 tsp onion powder
- 1/2 tsp black pepper
- 1/2 tsp paprika
- 2 tbsp olive oil (for brushing before grilling)
Instructions
- Grab a medium bowl and whisk together the soy sauce, Worcestershire sauce, minced garlic, onion powder, black pepper, and paprika until everything’s completely combined—about 30 seconds of good whisking.
- Place your London broil steak in a shallow dish (a 9×13 baking dish works perfectly) and pour that marinade right over it. Flip the steak a couple times to make sure every inch gets coated, then cover tightly with plastic wrap and stick it in the fridge. Let it marinate for at least 4 hours, but overnight is when you’ll really taste the difference.
- When you’re ready to cook, preheat your grill to medium-high heat—around 450°F if you’ve got a thermometer.
- Pull that steak out of the marinade and pat it completely dry with paper towels until it practically squeaks (this is important for getting good char). Brush both sides generously with olive oil so it doesn’t stick.
- Slide the London broil onto the grill and let it do its thing for about 5-7 minutes per side for medium-rare (125°F internal temp), or cook a bit longer if you prefer it more done. Don’t stress—just keep an eye on it since these steaks cook fast.
- This part takes patience: remove the steak from the grill and let it rest for a full 10 minutes before slicing. I know it smells amazing, but trust me, this keeps all those juices inside the meat.
- Slice thin against the grain (look for those muscle fibers and cut perpendicular to them). Pile those beautiful slices on a platter and watch them disappear!
