Flank steak is a beef cut that is long, thin, and lean. It’s one of the more cheap pieces of meat, but if it’s not cooked properly, it can be quite tough.

The use of a marinade for flank steak tenderizes the meat while also infusing it with flavor. It cooks rapidly on the grill, but it also works well in a grill pan or cast iron skillet on the stove.

On high heat, it is swiftly cooked. There is no fat in the flank steak. The hue of the steak is a darker crimson with brown textures. It comes from the cow’s abdominal region.

London broil is another term for flank steak. There are various ways to prepare flank steak, but knowing the right way to cook it is crucial for bringing out the true flavor.

Are flank steak and skirt steak the same thing?

No, but on the cow, flank steak and inside skirt steak are located near each other. Because they are both long and thin pieces of beef, they are frequently confused. 

The flank steak and the inside skirt steak come from the cow’s abdomen, which means they have tough muscle fibers from years of use.

One of the most popular summer steak recipes is grilled flank steak with sorrel sauce. Allow the meat to marinate for an entire day before grilling it for dinner.

Make sure your grill is very hot and that you cook it thoroughly. Place the flank steak in a baking dish, stab it 10 times with a fork, cover it with new plastic, and refrigerate it overnight.

After that, lightly lubricate the grill and set it to preheat.

Grill flank steak for 5 minutes once the grill is hot. After that, heat it for another 3-4 minutes.

Then, on a chopping board, place the cooked meat and cover it with aluminum foil for 15 minutes.

Grilled flank steak with mushrooms can also be prepared, and they come in various flavors. It all depends on your personal preferences.

By the way, single-grilled flank steak is also great; adding mushrooms, herbs, and other ingredients enhances the flavor.

Grill flank steak is best cooked over high and direct fire.

Before you start cooking, heat your grill on both sides. Cook for 2 minutes on each side. Flap steak grilling is a form of art.

Chuck, rib, short loin, and flank steaks are the best for grilling. Grilling flank steak can be done in various ways, and understanding how to prepare flank steak is essential.

Why does grilling flank steak take so long?

The steak will taste awful and be difficult to eat if it is not cooked properly. Muscles are difficult to digest.

Getting decent meat from a reputable store is crucial because quality counts. If you cook it for longer than the recommended time, it will get spoiled due to overcooking. 

Flap steaks that have been overcooked become significantly more difficult to chew. Making the surface of a grilled flank steak dry beforehand by cutting it into pieces is a better technique for cooking it.

Professionals use a thermometer to check the temperature and time while cooking, much like they would in a restaurant, since they want to prepare the perfect food.

The thermometer provides an accurate reading, and it is critical to keep track of time when cooking it.

It makes little difference whichever method you use for cooking, but you must keep track of the time and temperature. After preheating, the temperature should be between 125 and 140 degrees.

To prepare your steaks, marinate your grill. Because flanks are so thin, cooking them the right way takes less time.

Is it necessary to marinate flank steak?

While you don’t have to marinate flank steak, you’re sure to enjoy the flavor. Because flank steak doesn’t have a lot of fat, the marinade helps flavor the meat while also tenderizing it.

What is the best way to tenderize flank steak?

Tenderize the meat with an excellent marinade that contains both salt and acid. Because flank steak is so thin, a quick dip in the marinade is all it takes—around 30 minutes.

The salt and acid can work against the steak and make it tough if it sits too long.

Get the right cut

Begin by purchasing a deep red flank steak with a modest amount of fat along the muscle lines from a reputable vendor. It’s also a good idea to look for a flank steak that’s as evenly sized as possible, so there aren’t any thicker sections that cook at various times.

The average flank steak should weigh between two and two-and-a-half pounds.

Because flank steak is naturally tougher than other steaks, it does require some planning ahead of time, but thankfully, this planning can take as little as an hour, rather than the time-consuming marinades that many people feel are required.

The marinating misconception is that anything other than salt does not permeate deep into the meat.

Sugars and spices have molecules that are too big to pass through small pores on the surface. So, no matter how long your steak sits in a perfectly prepared marinade, the tastes won’t do much more than if you poured them on top after it’s cooked. The salt holds the true secret.

Salt can change the structure of proteins and muscle fibers, making it particularly useful for tenderizing pieces of meat containing a lot of muscle.

This change makes the meat more tender and helps it retain more moisture, two of the most important qualities of a flank steak.

Depending on the qualities you want to impart to your steak, you can either dry brine it in salt, approximately a tablespoon dusted on both sides should suffice, or soak it in a salty marinade.

The salt is the easiest of the two, although marinating doesn’t hurt if you want to use the marinade as a sauce later after you boil it.

In either instance, you don’t need much more than an hour, and you don’t want to go much longer than that with a marinade that contains acids like citrus because it could make the meat tougher.

You also want to start cooking while your meat is at room temperature, so remove it from the fridge at least 45 minutes before cooking.

If your brine or marinate will only last an hour, don’t bother putting it back in the fridge.


A digital meat thermometer is the best way to tell whether your flank steak is done. You can use a probe thermometer to check whether your steak is done to your liking by inserting it into the thickest section of the meat.

I want my flank steak medium rare, but I don’t advocate cooking it any higher than 150 degrees Fahrenheit because it will become tough and dry.

Remember that flank steak needs to rest for at least 5 minutes before cutting into it, so remove it from the fire a few degrees before you achieve your preferred temperature, as it will continue to cook while resting.

  • Rare: 130 degrees Fahrenheit
  • Medium rare: 135 degrees Fahrenheit
  • Medium: 145 degrees Fahrenheit
  • Medium well: 150 degrees Fahrenheit
  • Well done: 160 degrees Fahrenheit

Tenderizing flank steak

Because flank steak is a lean cut, it lacks the fat content of other steaks. During the cooking process, fat breaks down, naturally tenderizing the meat.

You’ll need to tenderize the beef manually if it’s lacking in fat. There are two great ways to cook flank steak.

Using a meat tenderizer is the quickest method. Place the steak in a plastic food storage bag to do so. Remove all air from the bag before sealing it tightly.

Place the bag on a chopping board, flattening the meat. Pound the steak with the meat tenderizer, ensuring to work the instrument uniformly across the meat.

Making a marinade is your second choice. This takes longer because you must marinate the meat for at least a few hours, if not overnight.

You’ll need salt, oil, an acid (lemon juice, balsamic vinegar, soy sauce, or Worcestershire sauce), brown sugar, and your favorite steak spice blend to make a marinade.

Popular seasonings include black pepper, garlic, and thyme. Combine all of the ingredients in a food storage bag with the steak and marinate for several hours before cooking.

Final thoughts

The most important factor is taste. Everyone in the world enjoys eating delectable meals. And some of them enjoy preparing non-vegetarian meals.

It is one of the healthiest meats since it has a lot of calories, protein, vitamins B6 and B12, and has no sugar, fat, or carbohydrates. The tray should be coated properly before grilling so that the meat does not stick.

It’s easy to customize because the sharp flavor pairs nicely with a wide range of spices and condiments. 

People prefer their steaks to be tender, and the sides might be crunchy. If you spin it too much, the flavors flow into the grill tray instead of adhering to the surface.

Cooks can avoid such issues by poking the meat properly.
