Notes

How To Slice Flank Steak:
  1. Freeze your beef. Place the steak in the freezer for up to 30 minutes before slicing. This allows for easier uniform slicing.
  2. Cut across the grain. Look at the flank steak as a whole and determine which direction the muscle fibers are running. Then line your knife up perpendicularly (your knife should make a T with the fibers, so that you’ll be cutting through the fibers, not parallel to them) and slice.
  3. Slice your steak in thin strips. Slicing flank steak in thin strips cuts through the tough fibers helping you get a more tender, easier-to-eat bite of meat.
  4. Cut into even-sized pieces. For best results, be sure to cut your steak into even-sized strips so it will cook evenly in the crockpot. 
  5. Use a sharp knife. Using a sharp knife helps ensure the cleanest cut of beef.
