What is a flank steak?
Flank steak is a cut of beef that comes from the belly of a beef animal. It is a lean steak (only 6 grams of fat per serving!), with long fibers and a rich beef flavor. It’s important to slice this cut against the grain to break up those coarse fibers.
Flank steak is more moderately priced than some of the “glory steaks” like ribeyes or tenderloin filets, and are sized to effectively feed several people with one steak, as they will weigh 1.5 – 2.5 pounds each.
What does a flank steak taste like?
Flank steak is a less tender cut of beef. This is due to the location of the steak coming from an area where the muscles are frequently used. However, when you cut the steak against the grain, you can break up some of the tough fibers.
Flank steaks have an intense beef flavor – think of a pot roast like flavor instead of a strip steak flavor. This bold flavor is perfect for recipes that have significant seasonings in them, as the beef flavor does not get lost in the background.
Why do you marinate flank steaks?
Marinating flank steaks helps accomplish two things:
- Marinating adds flavor, and since flank steaks have big flavor, they can be enhanced by additional flavors from marinades.
- Marinating adds moisture, which helps the flank steak seem more tender. Marinating doesn’t actual “tenderize” the meat, but having that extra moisture on the outside helps it seem more juicy!
What’s the marinade for this marinated flank steak?
We are using a classic American steakhouse-style marinade with big bold flavor and a boost of umami. For this recipe, we made a marinade from scratch, but you can use a pre-made marinade to save time. LGCM’s Authentic Steakhouse Marinade is a sure bet for this recipe!
Our marinade for this Stekahouse Marinated Flank Steak recipe is as follows:
- 1/2 cup Worcestershire sauce
- 1/4 cup soy sauce
- 1/4 cup vegetable oil
- 2 cloves minced garlic
- 2 tbsp. brown sugar
- 1 tbsp. tomato paste
- 2 tsp. kosher salt
- 1 tsp. black pepper
Mix these ingredients together, put your flank steak into a sealable plastic bag, dump in the marinade, and work the marinade into the meat. Let it sit for at least 10 minutes, or as long as overnight.
The marinade will not penetrate the meat, so you don’t need to let it rest very long if you’re short on time!

Heat your grill to medium heat (375ºF) and set it up for direct grilling. Remove the flank steak from the marinade and discard the marinade.
Place the steak directly over the heat and grill for about 6 – 8 minutes per side, flipping once, until the steak reaches an internal temperature of 135ºF for medium doneness.
Once the steak is done cooking, remove from the grill and wrap in foil, and let it rest for 15 minutes before slicing. Wrapping and resting will let the steak cook evenly throughout and help it retain its juices while you cut it.
After the steak has rested, slice the steak, against the grain, into strips. Serve with your favorite potatoes and green vegetables (and maybe a glass of red wine) and enjoy!
