Ingredients for Your Marinated London Broil

Alright, let’s talk ingredients! This is where the magic starts for our marinated London broil. You’ll need a good quality cut for this, about 2-3 pounds of London broil steak. Don’t worry if you’ve never seen it before, it’s a cut that really benefits from a good marinade and a quick sear.

For the marinade, gather up:

  • 1/2 cup soy sauce (this is our salty, savory base!)
  • 1/4 cup olive oil
  • 1/4 cup red wine vinegar (for that little tang)
  • 2 tablespoons Worcestershire sauce (adds another layer of umami)
  • 2 cloves garlic, minced (fresh garlic is key here!)
  • 1 teaspoon black pepper
  • 1 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary
  • 1/4 teaspoon cayenne pepper (just a tiny pinch for a little warmth, don’t go crazy unless you like it fiery!)

That’s it! Simple, right? These are all pantry staples for me.

Mastering the Alton Brown London Broil: Step-by-Step Instructions

Alright, let’s get this show on the road! Making a fantastic steak dinner doesn’t have to be complicated, especially when we’re following a plan inspired by Alton Brown and focusing on simple, delicious results. Trust me, by following these steps, you’ll have a perfectly cooked, juicy London broil that everyone will rave about. It’s all about a few key techniques that make a huge difference.

Preparing the Flavorful Steak Marinade

First things first, we gotta make that magic marinade! Grab a bowl and toss in the soy sauce, olive oil, red wine vinegar, Worcestershire sauce, minced garlic, black pepper, thyme, rosemary, and that little pinch of cayenne. Give it a good whisk until everything is nicely combined. This marinade isn’t just for flavor, though it certainly does that; it also helps to tenderize the steak, especially important for a cut like London broil. Making your own marinade also means you know exactly what’s going in – no weird stuff!

Marinating for Maximum Flavor

Now for the patient part, but oh so worth it! Take your beautiful London broil steak and pop it into a big resealable bag or a shallow dish. Pour all that yummy marinade over the top, making sure every single inch of the steak gets coated. Then, it’s into the fridge it goes. I always aim for at least 4 hours, but honestly, overnight is where the real flavor party happens. My kitchen counter is usually covered in these little bags of goodness the night before a big dinner. It just ensures that every bite is absolutely packed with flavor.

How to Broil Steak to Perfection

Okay, time to get this steak cooked! First, make sure your broiler is preheated to high. It needs to be nice and hot! Once the steak is done marinating, take it out and pat it THOROUGHLY dry with paper towels. This is super important – a dry surface means you’ll get a better sear. Discard the used marinade, we don’t need that anymore. Now, place your steak on a broiler pan. Broil it for about 5-7 minutes per side. I usually aim for medium-rare, which is around 130-135°F on a meat thermometer. If you like yours more done, just let it go a bit longer, but keep an eye on it! You want that juicy flank steak goodness, not something dry.

The Crucial Resting and Slicing Technique

Here’s a step that too many people skip, and it’s a big one: *resting* the steak! Once it’s out of the broiler, let it sit on a cutting board for a good 10 minutes. No peeking, no slicing early! This allows the juices to redistribute throughout the meat, making it way more tender and moist. After it’s rested, it’s time to slice. Find the direction the muscle fibers are running (that’s the grain) and slice thinly *against* the grain. I cannot stress this enough – slicing against the grain is the secret sauce to making this steak incredibly tender. As you practice these techniques, it’s always good to be aware of our site policies and you can find those at our terms of use page.

Tips for the Best Alton Brown London Broil

You know, even with a great recipe, a few little tricks can make all the difference. When I’m making this Alton Brown London broil, I always keep a few things in mind to make sure it turns out perfectly juicy and flavorful every single time. First off, don’t skimp on the marinating time – overnight is truly your best friend here! Also, make SURE you pat that steak really, really dry before it hits the broiler. Seriously, no paper towels spared! And when it comes to slicing, always go against the grain. I learned that the hard way early on, thinking I was saving time but ending up with a tougher steak. Now, it’s the last step I do after it rests!

Serving Suggestions for Your Easy Steak Dinner

So, you’ve got this absolutely amazing, marinated London broil ready to go. What do you serve with it? I love keeping things simple and fresh to let the steak shine. Think classic steakhouse vibes! A big, crisp green salad with a vinaigrette is always a winner. Roasted asparagus or green beans are fantastic, especially if they’re tossed with a little garlic and olive oil. And for potatoes? You can’t go wrong with some creamy mashed potatoes or even some simple roasted fingerling potatoes. It’s all about creating a balanced and satisfying meal that feels special but is still totally easy.

Frequently Asked Questions About Marinated London Broil

Got questions about making this amazing steak? I’ve got answers! This Alton Brown London broil is pretty straightforward, but here are a few things people often ask.

Can I grill this instead of broiling?

Absolutely! Grilling is a fantastic option, especially if it’s nice out. You’ll want to get your grill nice and hot, just like you would your broiler. Sear the steak for a few minutes per side over direct high heat to get those lovely grill marks and a good crust. Then, you might want to move it to a slightly cooler part of the grill to finish cooking to your desired doneness. It’ll give you a slightly different, smoky flavor that’s also delicious.

What’s the best way to store leftovers?

If by some miracle you have any leftovers of this juicy flank steak, just pop them in an airtight container in the fridge. They should be good for about 2-3 days. My favorite way to use leftover steak chunks is chopped up in a salad or quickly reheated for a steak and veggie stir-fry. Just make sure it’s cooled before it goes in the fridge!

How long can I marinate the steak?

This is key for an easy steak dinner! For this particular marinated London broil recipe, Marinating your London broil for at least 4 hours is good, but honestly, overnight is where the magic really happens. The longer it marinates, the more tender and flavorful your steak will be. I’ve even gone up to 24 hours with no problem! Longer marinating times really allow those flavors to penetrate deep into the meat.

Do I really need to slice it against the grain?

YES! Seriously, this is non-negotiable if you want a tender bite. Slicing against the grain is the secret sauce to making cuts like London broil incredibly tender and enjoyable. If you slice with the grain, you’re basically cutting along those long muscle fibers, which can make the steak chewy. Slicing against them shortens those fibers, making each piece melt-in-your-mouth tender. Trust me on this one!
