Grilled Flank Steak
Flank steak is a lean and boneless cut of beef with lots of intense meaty flavor. It comes from the bottom abdominal area of the cow, right below the loin. This relatively long and flat cut of beef has little marbling and it is a relatively tough cut of meat. Flank steak is also sold under the names of London Broil, Jiffy Steak, Plank Steak and Beef Flank.
How To Cook Flank Steak
MARINATE: Flank steak benefits greatly from soaking in a tasty marinade before it’s cooked. A marinade not only enhances the flavor of the steak but also helps tenderize the meat.
COOK OVER HIGH HEAT: High heat and fast cooking are the best ways to cook flank steak. Grilling, stir frying and pan searing are some of the most common ways to cook this cut of meat.
FOR BEST RESULTS: Flank steak is most tender and juicy when cooked to medium-rare and thinly sliced at an angle against the grain (across the grain).
Grilled Flank Steak Marinade
This melt-in-your-mouth tender grilled flank steak marinate reminds me of the amazing flavors of Korean Bulgogi. Here are the ingredients:
- Soy Sauce – If following a gluten free diet, use tamari instead.
- Cola – You heard that right! Use your prefer cola beverage.
- Brown Sugar – You can use honey instead.
- Garlic – I use fresh garlic.
- Ginger – I use fresh ginger.
- Oil – A mild oil is best. Vegetable, canola or olive oil can be used. I prefer to stay away from extra virgin olive oil as it has a distinct strong fruity flavor.
- Sesame Oil – Also known as Asian sesame oil or roasted sesame oil.
- Black Pepper
How To Make This Korean Style Grilled Flank Steak
- Trim your flank steak if needed. Some flank steaks are sold with a thin membrane still attached. Remove it before marinating and grilling the steak.
- Pierce the steak with a fork before marinating. This allows the marinade to penetrate the meat a bit better.
- Mix the marinade ingredients in a resealable bag or in a large casserole or baking dish that fits the flank steak comfortably.
- Add the steak to the marinade and massage the marinade into the meat. Seal the bag, or cover the container and marinate in the refrigerator for up to 4 hours.
- Preheat a grill or grill pan over high heat. A gas grill should reach 400 to 450 degrees Fahrenheit.
- Carefully grease the grill grates.
- Remove the meat from the marinade and allow any excess marinate to drain.
- Place the meat on the hot grill and cook, uncovered, for 4 to 5 minutes. Flip the meat and cook on the other side until the meat reaches your desired temperature of doneness.
- Remove the meat from the grill and transfer it to a cutting board. Tent the meat with aluminum foil and let it rest for 10 minutes.
- Slice the steak thinly against the grain.
