Keto Broiled Flank Steak
We don’t eat a lot of red meat in our house, maybe once a week. So when we DO decide to cook steak, I have some very strict standards.
First, it’s needs to be tender. Second, it has to be flavorful.
I usually find flank steak a bit tough and bland. So the opposite of my requirements. But it’s such a great price, I wanted to find an easy recipe that could transform this cut.
This is the one!
Not to mention, the leftover opportunities are endless. Maybe steak and eggs, or a nice steak salad. Or, substitute this steak for the lamb in my Keto Lamb Fajitas recipe (and just skip the step where you cook the meat!)
Do I Actually Need To Marinate The Flank Steak?
Marinating the flank steak is the key to adding flavor and breaking down the meat.
You’ll want to score the meat (I like to score it along the grain, but it’s up to you) on both sides and then let it marinate for a minimum of 30 minutes.
Some people even recommend marinating flank steak overnight!
So, do you NEED to marinate your flank steak? Technically, it will still be an edible steak if you don’t… but it will certainly be a lot better if you do.
For this recipe, I say yes, marinating is a requirement.
Is Broiled Flank Steak The Same As A London Broil?
Yes, this style of cooking your steak can also be referred to as a London Broil.
London Broils typically involve a top round steak, but you can use flank steak as well.
But the name London Broil can have a bad connotation. For some, it makes them think of a tough, flavorless steak that they’d rather bury in the backyard than eat.
That’s why I prefer to refer to this recipe simply as Keto broiled flank steak. No negative preconceived notions!
How Do You Cut A Flank Steak?
You always want to cut flank steak at an angle, against the grain.
I also like to slice my flank steak pretty thin!
How To Make Broiled Flank Steak
To prep the flank steak for the marinade, score both sides of the meat. This will allow the marinade to really soak into the steak. I like to score it along the grain, but again, it’s up to you.
Sprinkle both sides with thyme, freshly ground pepper, and salt. Use your fingers to press the seasoning into the meat so it sticks.
In a glass baking dish or ziplock bag, add the “No Soy” sauce or coconut aminos. Add the flank steak to the dish or bag and coat all sides of the meat. Marinate for a minimum of 30 minutes. The longer, the better!
When the marinating time is almost up, preheat the oven to broil, usually 500 degrees F.
Line a baking sheet with aluminum foil for easy cleanup. You can use a baking wire rack as well, but it’s optional.
Remove the steak from the marinade, set it on your pan or rack, and broil for 8 minutes per side (or until your desired doneness).
Let the meat rest for 5 minutes, then thinly slice the meat at an angle and against the grain to serve.
