How To Marinate Flank Steak
Marinating flank steak is as easy as falling off a log. But there are a couple of techniques to keep in mind.
Flank steak is flavorful, lean and a somewhat tough cut of meat that benefits from an overnight soak that includes an acid such as vinegar, lime or lemon juice. This helps break down the connective tissue to produce a tender cut of meat, once cooked.
Along with your choice of acidic liquid Just throw in some of your favorite seasonings.
I’ve seen recipes that instruct one to score the meat with a sharp knife to encourage the flavor to penetrate the steak. Which seems to make sense,
However, I’m sticking by the golden rule of never piercing your meat. You want the end result to be as juicy and flavorful as possible. Any kind of piercing, jabbing as you cook, or cutting will release valuable juices.
Please use tongs when turning your meat.
All you need for this overnight flank steak marinade are simple ingredients and a zip lock gallon bag.
How Long Can You Marinate Flank Steak?
Culinary School offered this advice and flank steak marinade time. Flank steak can be marinaded for as short of time as 2 – 3 hours, or up to 12 hours to enhance flavor and tenderness. A 24 hour marinade is discouraged, especially when acids like lemon juice, or lime juice are involved. They can encourage the steak to become mushy.
Does Flank Steak Have to Be Marinated?
To marinate or not to marinate? That is the question. Although marinating is fine for a flank steak, it most certainly isn’t a requirement.
I have grilled many flank steaks that have produced very tender results without a marinade. The secret is to make sure you don’t overcook the steak, and then slice it thinly in the opposite direction to how the grain of the meat is running.
And in leu of the marinade, just rub the flank steak with your favorite seasonings before grilling. A good example is this recipe for Grilled Flank Steak with Caramelized Sweet Corn. A simple seasoning of salt and pepper is all you need.
