Expert Tips:

Buying and Prepping Your Beef Properly:

  • Choose the best quality flank steak you can afford.
  • Beef can handle a longer marinating time than chicken or seafood. Marinate your flank steak overnight or at least 8 hours if possible. The longer the steak is in the marinade, the more flavor infuses into the meat via osmosis.
  • If you’d like, lightly score the steak on both sides with a sharp knife (making shallow cuts, about 1/8-inch deep, 1-inch apart, against the grain). This will increase the surface area for the marinade to infuse. This will also help prevent the meat from curling when it hits the grill.

Cooking Your Flank Steak:

  • I like to grill for a few minutes on one side, then rotate the steak about 45 degrees to make lovely hash marks. Repeat on the other side. Times will vary depending on the thickness of your flank steak and how well done you like your meat cooked.  Use an instant-read meat thermometer to check the temperature with each turn or flip and adjust accordingly.
  • Pull your beef off the heat at 115 degrees which allows for the meat to come up another 10 degrees as it rests under foil for 10 minutes before carving for rare beef.

Slicing Your Flank Steak:

  • PRO-Tip: Flank steak needs to be cut against the grain to ensure tender slices, which means you need to look for the grain or “lines” in the beef and cut slices in the opposite direction. With flank steak, it’s usually cutting from one long side to the other (making shorter slices than if you’d cut in the other direction).
