Ingredients for Your Marinated London Broil

Alright, for this amazing marinated London broil, you’ll want to round up these goodies. I always try to have them on hand because you never know when a steak craving will strike! You’ll need one good-sized London broil or flank steak, about two pounds – pick one that looks nice and red at the butcher counter.

For that incredible marinade, grab:

  • 1/4 cup soy sauce (gives it that deep, savory kick!)
  • 1/4 cup olive oil (for richness and helping the flavors meld)
  • 2 tablespoons Worcestershire sauce (don’t skip this, it’s pure umami gold!)
  • 1 tablespoon Dijon mustard (just a little tang)
  • 1 tablespoon honey (for a hint of sweetness to balance things out)
  • 2 cloves garlic, minced (fresh garlic is key here, trust me!)
  • 1 teaspoon black pepper (freshly ground, if you can!)
  • 1 teaspoon dried thyme (adds a lovely savory note)

That’s it! Simple, right? All stuff you probably already have or can grab easily.

Essential Equipment for How to Broil Steak

Alright, before we get this show on the road and learn how to broil steak like a pro, let’s make sure you’ve got your game face on and your trusty kitchen tools at the ready. For this Alton Brown London broil, you’ll definitely want a good broiler pan – that’s the one with the rack so the heat can circulate all around the steak. You’ll also need a resealable plastic bag or a shallow dish for marinating; I usually go for the bag because it’s easier for coating. And of course, have a whisk, a bowl, and a good sharp knife for slicing when it’s all done!

Crafting the Perfect Alton Brown London Broil Marinade

Okay, so making the marinade for this Alton Brown London broil is seriously one of the easiest parts, but it packs SO much flavor. It’s all about building layers! You just grab a medium bowl and whisk together the soy sauce, olive oil, Worcestershire, that little bit of Dijon mustard (which adds a nice tang, by the way!), and the honey. Trust me, the honey balances everything out beautifully and helps with that gorgeous sear. Then, toss in your minced garlic and dried thyme. Give it all a really good whisk until it looks all combined and delicious. I like to use a small whisk for this, it just gets everything really well incorporated. Don’t forget that black pepper! This marinade is really the heart of what makes this steak so good, and I even have a few more marinade secrets I love to use for other cuts, but this one is perfection for London broil.

Marinating Your London Broil for Maximum Flavor

Now for the part that really makes this Alton Brown London broil sing: the marinating! This is where all that amazing flavor gets to soak deep into the meat. You’re going to pop that steak into a resealable bag or a shallow dish – I usually go for the bag because it makes sure every bit of steak gets coated. Pour that gorgeous marinade you just whipped up all over it. Give the bag a little shake or gently turn the steak in the dish to make sure it’s completely covered. Feel it coating the meat? Lovely! Then, seal it up tight and pop it in the fridge. You can marinate it for at least 4 hours, but honestly, for the absolute best flavor and tenderness with this Alton Brown London broil, I like to let it go overnight. It just makes such a difference!

Step-by-Step Instructions for Your Easy Steak Dinner

Alright, let’s get this incredible, flavorful steak dinner cooking! It’s really straightforward once you get the hang of it. First things first, you need to get that broiler screaming hot. I usually position my oven rack about 4-6 inches from the heat source. This gives the steak enough space to cook without burning, but close enough to get that lovely char. Now, take your steak out of that yummy marinade and, here’s a small but important tip, gently blot it dry with a paper towel. This helps get a better sear. And here’s a little something Alton Brown taught me – never, ever reuse that marinade after the raw meat has been in it! Just ditch it. Learning the basics of broiling really makes a difference!

Preheating and Preparing the Broiler

Preheating your broiler is crucial for that perfect, restaurant-style crust. Turn your broiler to its highest setting – usually ‘HI’. Let it heat up for a good 5 to 10 minutes. While it’s heating, make sure your oven rack is adjusted so the steak will be about 4-6 inches away from the heat element. This distance is key to getting that nice sear without scorching the outside before the inside is cooked.

Broiling Your Juicy Flank Steak to Perfection

Now for the moment of truth! Place your beautifully marinated and blotted flank steak on the heated broiler pan. Pop it under that broiler. For a perfect medium-rare on a 2-pound steak, I usually go about 5-7 minutes per side. Keep an eye on it, though! Broilers can be fierce. To check for doneness without cutting into it, you can use a meat thermometer. For medium-rare, you’re looking for an internal temperature of about 130-135°F. If you like it more done, just give it a few extra minutes per side. The goal is a beautiful, browned exterior and a perfectly juicy flank steak inside!

Resting and Slicing Your London Broil

Okay, resist the urge to cut into it right away! This is SO important for a juicy steak. Once it’s done, transfer the steak to a cutting board and let it rest for a good 10 minutes. This allows all those delicious juices to redistribute throughout the meat, so you don’t lose them all onto the board. When it’s ready, slice it thinly. The absolute best way to do this is against the grain. Look closely at the steak – you’ll see the direction the muscle fibers are running. Slice right across those fibers, perpendicular to them. This breaks them down, making the steak incredibly tender and easy to chew. It makes all the difference!



Tips for Success with Your Alton Brown London Broil

You know, getting a fantastic Alton Brown London broil isn’t just about following the steps; a few little tricks up your sleeve can make it even better. When you’re picking out your steak, look for a nice, even thickness. This helps it cook more evenly under the broiler. If one end is way thicker than the other, you might end up with one part perfectly cooked and the other overdone. And about that marinade? Don’t be afraid to experiment a little! Alton Brown himself is all about understanding the ‘why,’ so you can totally tweak things. Maybe add a pinch of red pepper flakes if you like a little heat, or swap the thyme for rosemary. Just remember, the longer it marinates, the more flavor it’ll take on, but don’t let it sit in the fridge for more than 24 hours, or the acidity can start to break down the meat a bit too much. Seriously, this Alton Brown London broil recipe is pretty forgiving, but these little touches really elevate it!

Serving Suggestions for Your Steak Dinner

So, you’ve got this incredible, juicy London broil ready to go – high five! Now, what do we serve with it? Honestly, this steak is so versatile, it pairs beautifully with almost anything. For a classic, hearty steak dinner, you can’t go wrong with some creamy mashed potatoes or some crispy roasted potatoes. If you’re feeling a bit more spring-like, a bright, fresh salad with a light vinaigrette is amazing, or some simple steamed asparagus with a squeeze of lemon. I also love serving it with some grilled corn on the cob when it’s in season. It really makes the whole meal feel complete and oh-so-satisfying!

Storage and Reheating Your Marinated London Broil

Okay, so you might have some of this amazing marinated London broil leftover (if you’re lucky!), and you want to make sure it’s just as good the next day. The key here is to store it properly so it doesn’t dry out. Once your steak has cooled down a bit, slice it thinly against the grain (remember how we talked about that?). Then, pop those slices into an airtight container. You can add a tablespoon or two of broth or even just a little water to the container before sealing it – this helps keep it moist. It’ll stay good in the fridge for about 3-4 days.

When you’re ready to reheat, try not to blast it with high heat. The best way is to gently warm it up. You can pop those slices back into a baking dish with a little extra broth or water, cover it with foil, and warm it in a low oven (around 300°F or 150°C) for about 10-15 minutes, just until it’s heated through. Avoid microwaving if you can, as it tends to toughen the meat. The goal is to revive that tender, juicy goodness from your marinated London broil without making it tough!

Frequently Asked Questions about Alton Brown London Broil

Got questions about making the best Alton Brown London broil? I totally get it! Cooking steak can feel a bit tricky sometimes, but this recipe is pretty foolproof. Here are a few things folks often ask.

Can I grill this London broil instead of broiling?

Absolutely! Grilling is a fantastic way to cook this Alton Brown London broil, especially when the weather is nice. Just preheat your grill to medium-high heat and cook the steak for about 5-7 minutes per side, just like you would under the broiler. Make sure to get those nice grill marks!

What is the best way to slice London broil?

This is super important for tender meat! Always slice your London broil thinly against the grain. Look for the lines where the muscle fibers are running, and cut right across them, perpendicular to those lines. This breaks down the fibers, making every bite melt-in-your-mouth tender. Don’t skip this step!

How long can I marinate the steak?

For this Alton Brown London broil, I recommend marinating for at least 4 hours, but overnight is truly where the magic happens – up to 24 hours is great. The marinade really works its way into the meat. Any longer than that, though, and the acid in the marinade might start to break down the meat too much, making it mushy instead of tender.

Nutritional Information for Your London Broil

Okay, so when we’re talking about this delicious London broil, it’s good to have a general idea of what you’re eating. These numbers are estimates, of course, since everyone’s kitchen is a little different and ingredients can vary! But as a general guide, a serving (about 4 ounces) is roughly 350 calories, with about 20g of fat and a solid 35g of protein. It’s a pretty satisfying meal!
