How to make flank steaks tender
The Flank steak is a cut of beef taken from the abdominal muscles or lower chest of the steer. This steak comes from the well-exercised part of the cow and it can be tough. Who knows why this part of the cow gets so much exercise maybe they do sit ups and crunches? (smiling) Therefore, there are a few things that need to be done to keep this cut of meat tender and delicious.
- Remove any tough fascia from the flank steak before marinating.
- Marinate your flank steak in the refrigerator. The longer you marinate it the better. We like to marinate our steaks the night before so that they have about 24 hours to do their thing. However, you can also marinate them for just 2 hours, but they are not as tender as when you do it overnight.
- Be sure to take your flank steaks out of the refrigerator at least 20 - 30 minutes before grilling to allow the steaks to come to room temperature. Don’t be putting a cold steak on a hot grill! If you put a cold steak on a hot grill they want to shrivel, and it won’t cook evenly. The goal is to cook your steaks quickly over a higher heat to get a nice sear and keep them tender and let them cook evenly.
- Do not overcook the steaks. Cook to a medium rare. Do not cut your steak until after it is cooked.
- Let your flank steak rest for about 10 minutes under aluminum foil before carving and slice very thin. This helps keep the juices in your steak.
- Make sure you cut against the grain of the steak and not with the grain of the steak.
Best Steak Marinade
Just a handful of pantry ingredients make this marinade extra special. Ok, the secret is out! This savory flank steak marinade is fantastic for meat but is also fantastic for mushrooms and grilled veggies too. Just to note, vegetables and mushrooms only need to be marinated for about 15 minutes unlike a steak that needs at least 2 hours or up to 24 hours. For about a 1.5 pound flank steak we marinate our flank steaks with the following ingredients…
- Olive oil
- Soy sauce or Tamari sauce for gluten-free
- Aged balsamico from Mie Radici – it is naturally sweet from the aging process so there is no need to add a sweetener to this recipe as some do.
- Fresh garlic
- Fresh minced onion
- Italian dried herbs
- Fresh ground pepper

As for a time estimate, we cooked our 1.5 pound (680 grams) for about 4-5 minutes on each side. However, everyone’s heat level can be different depending on if you have a gas grill or coals, etc. So, it is best to go by internal temperature or finger test for best results.

Frequent Asked Questions (FAQ's)
Flank steak is a very lean piece of meat. It needs to be cut super thin and across the grain to keep it tender. This process helps cut though those tough fibers lending it to a tender bite. Look at the flank steak and look to see what way the long muscle fibers are running. Then, line your knife up to cut perpendicular though the fibers and across the grain. Do not cut parallel with the muscle fibers but across or perpendicular the muscle fibers. This method ensures a tender bite.
It is best to marinade flank steaks for at least 2 hours, but it is optimal to marinade overnight to ensure tenderness. Marinating your steak with acid (balsamic vinegar), fat (olive oil), Italian seasoning and fresh herbs and spices not only tenderizes the meat but also makes it extra delicious and gives the steak extra flavor.
Flank steak is from the bottom abdominal area of the cow. This area of the cow gets quite a workout. This cut of meat has a lot of tough fibers running through it and a very lean cut of beef. A flank steak is thicker, and wider compared to a skirt steak. In addition, generally the muscle fibers run lengthwise.
Skirt steak is from the diaphragm muscles of the cow. The cut of meat is much thinner compared to a flank steak and is much longer. In addition, it is very lean cut of meat. We think it has even more tough muscle fibers than a flank steak. The muscle fibers run horizontally across a skirt steak.
Either a flank steak or skirt steak can be used in our Marinated Grilled Flank Steak recipe.
