The Best Sous Vide London Broil
If you love London broil, just wait until you try making it using the sous vide method. I promise you and your family will be fighting for the last bite!
Seriously, it's so good. This sous vide London broil recipe marinates flank steak in a combination of garlic, brown sugar, soy sauce, and Dijon mustard. Then, after soaking up those delicious flavors, it's slowly cooked to make the meat tender and juicy. And to finish it off, the flank steak is pan seared to give it an irresistible crust.
And in addition to tasting incredible, this sous vide London broil is also a breeze to whip up. All you have to do is mix the marinade ingredients, coat the meat in it and let it sit, then patiently wait while the sous vide cooker does its thing.
While you're waiting, you can whip up some delicious sides to go with the meat. If you're looking for what to serve with London broil, my go-to recipes are this Velveeta broccoli casserole or this cauliflower casserole for an elevated vegetable side dish.
INGREDIENTS
The ingredient list for this London broil recipe is pretty simple. In fact, I'm willing to be you already have most - if not all - of them at home already!
Anyway, check out all of the London broil ingredients:
- 2-3 lbs. flank steak or top round steak
- 4 garlic cloves, minced
- 2 tbsp. soy sauce
- 2 tbsp, brown sugar
- 1 tbsp, Dijon mustard
- 2 tbsp. Worcestershire sauce
- 1 tbsp. rice vinegar
- 2 tsp. salt
Super simple stuff, right?!
Now, when you go to the grocery store, you'll want to look for cuts labeled as "London broil round steak," "flank steak," or if you want a more inexpensive steak, look for "top round steak." Either of those will work great in this recipe.
By the way, this sauce is so good that you'll probably want to make it more often. So I highly suggest serving it atop this flat iron steak next!
HOW TO MAKE SOUS VIDE LONDON BROIL
The beauty of sous vide cooking is that you barely have to do anything, and the meat will cook perfectly every single time.
Just remember you'll need about 7 hours - plus 90 minutes of marinading time - to make the London broil, so keep that in mind as you plan your day.
Anyway, let's stop wasting time and get cooking!
STEP 1: MAKE THE MARINADE
First, take out a bowl and mix the garlic, soy sauce, brown sugar, mustard, Worcestershire sauce, rice vinegar, and salt together.
Once the sauce ingredients have been combined, cover the flank steak or top round steak with the marinade on each side and let it sit for about 90 minutes at room temperature.
STEP 2: SOUS VIDE THE BEEF
Once the 90 minutes are up, place the marinated London broil in a sous vide bag and remove the air using a vacuum sealer. Then you'll want to heat a sous vide water bath to 132°F, place the bag in the heated water bath, and let the meat cook for 7 hours.
STEP 3: REDUCE THE MARINADE
When the steak is done cooking, you can remove it from the bag and pat it dry with paper towels.
Next, grab a deep skillet or saucepot and add your leftover marinade sauce, along with the drippings from the bag, to the skillet. Now bring the sauce to a simmer and cook it for about 3-4 minutes until it reduces.
STEP 4: SEAR AND SERVE
Lastly, heat a cast iron skillet or griddle over high heat until it's smoking, and then you can add the meat to it. You'll want to sear the meat for about 1 minute on each side to give it that beautiful brown crust.
As soon as it's done, remove the seared London broil from the cast iron pan, slice thin, and serve your steak drizzled with the Dijon soy glaze.
Enjoy!
