Our grill gets a major work out in the summer. Burgers, chicken, chops…anything is fair game. Flank steak is a family favorite, but it must be marinated. I spied this recipe for Korean Grilled Flank Steak in the Sunday paper when visiting my mother-in-law. I knew my family would love this grilled beef!

Best Steak Marinade

The marinade recipe provided such a marvelous punch of flavor with the freshly grated ginger, soy, and sriracha. You can tone down or amp up the spiciness by adjusting the hot sauce amount. Either way, it’s a perfect entree for your summer BBQ.

Tips for Making This Korean Beef Flank Steak

Flank steak comes from the abdominal muscles of the cow and is quite lean, and therefore can be very chewy if not prepared correctly. Since beef is sturdier than fish or chicken, it can easily handle overnight marination. I place the marinade ingredients in a gallon Ziploc bag, agitate it to mix, then add the beef. Remove any excess air, place the bag on a plate, and refrigerate up to overnight.

Marinating and cutting thin slices across the grain allows for this flavorful cut to be quite tender and tasty. Look for the “lines” running from one side of the flank steak to the other. Do not cut following these lines, but instead, cut perpendicular to the lines. It makes a huge difference!

We all loved this entree. There was nary a word about the heat from the Asian chile-laced condiment. Take my word for it, this is one of the best beef marinades!
