A quick London broil marinade to make grilling beef simple and flavorful. Just four ingredients are all you need to season your steak to perfection.
Perfectly cooked steak is the goal of every carnivore. There is enough pressure to cook it just right, that removing any challenges to ensure it is seasoned well and flavorful only makes it that much easier. This Easy London Broil Marinade is quick, simple, and adds some great flavor to your meal.
Four Simple Ingredients
This easy London Broil Marinade needs only four ingredients that are staples in most pantries. Garlic, onion, extra virgin olive oil, and soy sauce. You can dice up the garlic and onions very small and mix them with oil and soy sauce. I like to combine everything into a rocket blender and blend it for about 10 seconds.
The soy sauce in the quick London Broil Marinade adds some nice color to the steak and creates great caramelization as it cooks. If you like to add some spice to the flavor, you could add a ¼ teaspoon of crushed red pepper to the marinade.
Once it is all blended, all you need to do is pour it over the steak and let it marinate for at least an hour. I like to put the steak in a plastic storage bag with a seal, and pour the marinade over it. This is a great way to ensure the steak gets all covered with the marinade and it is easier to fit into the fridge.
I also prefer the storage bag instead of a storage container, because you don't need to make as much marinade. I always feel marinading something in a plastic storage container requires more marinade.
How long to marinate the steak?
Put the marinating steak in the fridge. I like to marinate the steak for at least 30 minutes. If you have time, you can let it marinate for at least 4 hours or even overnight. It gives the steak more time to absorb the flavors.
But, 30 minutes is really all you need for this quick london broil marinade.
To ensure the flavor is evenly distributed throughout the steak, every hour or so, I will take the steak out of the fridge and massage it, leaving it in the plastic bag, and then return it to the fridge on the other side.
Preheat the Grill
After the steak soaks in the Easy London Broil Marinade for at least an hour in the fridge you are all set to cook. Pull the steak out of the fridge about 20 minutes before you are going to grill. It is important to allow the meat to come up to room temperature to allow for evenly cooking and doneness.
While the steak is waiting to be cooked, it is time to fire up the grill. I always preheat the grill to ensure I get a good sear on the meat. I like my steaks medium-rare, so a nice hot grill creates a good sear while ensuring I am not overcooking the steak.
If you are using charcoal, you will need to start the charcoal in a chimney about 30 minutes before you cook. Getting the grill hot before we cook, will give us those nice grilled lines that we like to see on our steak.
Grill the Steak
I love grilled steak, but it can be fairly easy to overcook it. When using a grill that you are unfamiliar with, it is definitely a challenge. The key is to use a spot on the grill that has even heat. We don't want to make steak in a slow cooker, so avoid any cool spots on the grill.
Once I put the steak on the grill, I may hit it with a little extra freshly ground black pepper. I love the earthy spiciness of the pepper.
To arrive at medium rare, we will cook the steak for approximately 3 to 4 minutes per side. Once it is done, remove it from the grill and let it rest for about 5 minutes. I recommend putting a piece of foil over it so that it doesn't cool too quickly. Then slice, serve and enjoy!
Serve this with a slice of Keto Brioche Bread for a great meal.
