How To Make Crock Pot Beef Flank Steak

1. Mix the marinade: In a small bowl, combine balsamic vinegar, olive oil, honey, Worcestershire sauce, Dijon mustard, garlic, salt, and pepper.
2. Add steak to slow cooker: Place flank steak in the slow cooker, pour marinade over it, and flip steak once or twice to coat.
