Gather Your Ingredients for the Perfect Alton Brown London Broil

Alright, let’s get our ducks in a row and gather everything we need for this amazing steak. It’s pretty straightforward, and honestly, using good quality stuff makes all the difference. You’ll want one beautiful London broil steak, about 2 to 3 pounds. For the marinade, we’re going to whisk together a half cup of soy sauce, a quarter cup of good olive oil, and another quarter cup of red wine vinegar – this is key for tenderizing!

Then, a couple tablespoons of Worcestershire sauce for that extra savory kick, a tablespoon of Dijon mustard, and about 4 cloves of garlic that you’ll want to mince up nice and fine. Oh, and don’t forget a teaspoon each of black pepper and dried thyme, plus a half teaspoon of red pepper flakes if you like a little zing. Trust me, the quality of these simple ingredients comes through loud and clear in the final dish!

Mastering the Marinade for Your Alton Brown London Broil

Okay, now for the *really* fun part – the marinade! This is where all that fantastic flavor for our Alton Brown London broil really sinks in. We’re going to whisk together our soy sauce, that lovely olive oil, and the red wine vinegar. That vinegar is like magic, folks, it starts to tenderize the steak even before it hits the heat! Then, we’ll add in the Worcestershire sauce for a deep, savory punch, smooth Dijon mustard, and those 4 minced cloves of garlic – don’t skimp on the garlic! Toss in your black pepper, dried thyme, and a pinch of red pepper flakes if you like a little warmth. This blend is what makes it a truly juicy flank steak. If you’re feeling adventurous, I sometimes add a tablespoon of honey or even some brown sugar from our other marinade favorites – it just adds this subtle depth. You’ll totally want to adjust these to your liking as you get more comfortable!

Marinating Tips for Maximum Flavor

Now, let’s talk marinating time, because it’s super important for a juicy flank steak. I like to pop the steak into a big resealable bag – it makes sure every single inch gets coated. You could use a shallow dish too, but the bag is just easier for me. Make sure that steak is fully submerged or coated in the marinade. Honestly, at least 4 hours is good, but if you can swing it and let it marinate overnight in the fridge, you’ll seriously taste the difference. It makes the steak wonderfully tender and packed with flavor!

How to Broil Steak to Perfection

Okay, people, it’s time to get this beautiful steak ready for its close-up! Broiling is honestly super simple, and Alton Brown certainly knows his stuff when it comes to getting it just right. First things first, you’re going to want to preheat your broiler to high. Get that oven nice and hot! While it’s warming up, grab your broiler pan. If yours isn’t non-stick, a little spray of cooking oil can help prevent any sticking drama. Place your marinated steak on the pan, letting any excess marinade drip off (we don’t need that pooling and causing flare-ups!).

Now, pop it under the broiler. For a classic medium-rare London broil, aim for about 5 to 7 minutes per side. But honestly, a meat thermometer is your best friend here – it takes all the guesswork out! You’re looking for around 130-135°F (54-57°C) for medium-rare. This recipe fits so perfectly into our meal planning strategies for a quick yet impressive dinner. You want that perfectly cooked steak? This is how you get it!

Resting and Slicing Your London Broil

Don’t you dare skip this step! Once your steak is out of the broiler, you HAVE to let it rest. Seriously, just let it sit on that cutting board for a good 10 minutes. This is crucial because it allows all those delicious juices to redistribute throughout the meat, so you get a tender, moist bite every time. Then, the magic trick for tenderness: slice it thinly *against* the grain. You’ll see the direction the muscle fibers are running, and you want to cut straight across them. It makes a world of difference for a super tender Alton Brown London broil!

Serving Suggestions for Your Marinated London Broil

This marinated London broil is fantastic on its own, but honestly, it really sings when you serve it with some yummy sides. I love pairing it with some simple roasted potatoes – they soak up any extra juices from the steak so well! Or, if you’re going for something lighter, a big, fresh green salad with a tangy vinaigrette is always a winner. You could even add some grilled asparagus or roasted broccoli. These simple additions turn your delicious steak into a complete and totally easy steak dinner that feels fancy but is still super approachable.

Frequently Asked Questions About Alton Brown London Broil

Got questions about making Alton Brown’s London broil? I get it! Cooking a perfect steak can feel like a big deal, but this recipe makes it super approachable. Let’s clear up any confusion so you can cook with confidence!

Can I grill this London broil instead of broiling?

Absolutely! You can totally grill this steak. Just preheat your grill to medium-high heat. Sear the steak for about 4-6 minutes per side, depending on thickness, until it reaches your desired doneness. Grilling gives it a fantastic smoky flavor that’s perfect for summer!

What is the best way to store leftovers?

The best way to store leftover cooked London broil is to let it cool completely, then wrap it tightly in plastic wrap or place it in an airtight container in the fridge. It should stay good for about 3-4 days. Reheat gently in a skillet over low heat or even for a few seconds in the microwave to keep it from drying out.

How do I know when my steak is done?

Honestly, the easiest and most reliable way is to use an instant-read meat thermometer! For rare, aim for 120-125°F (49-52°C). For medium-rare (which I love for this!), it’s 130-135°F (54-57°C). Medium is around 140-145°F (60-63°C). Just insert it into the thickest part of the steak, avoiding bone if there is any.

Nutritional Information

Just a heads-up, these numbers are estimates, okay? They can totally change depending on the exact brands you use or even how thick you slice your steak.
