"I'm not a fan of ground beef, but I like the flavor of sloppy joes. This recipe incorporates the flavor of the classic sandwich with the lean cut of flank steak and the ease of a slow cooker."

  1. Sprinkle the beef flank steak with steak seasoning on both sides. Heat olive oil in a skillet over medium heat until the oil shimmers, and place the flank steak into the hot oil. Quickly brown the steak on both sides, about 5 minutes per side. Set the beef aside.
  2. Stir brown sugar, onion, red bell pepper, apple cider vinegar, Worcestershire sauce, tomato sauce, and tomato paste together in a slow cooker until the brown sugar dissolves. Place the flank steak into the slow cooker, immersing it in the sauce. Set the cooker on on High and cook 4 hours, or set on Low and cook 8 hours.
  3. To serve, shred the meat with 2 forks, or remove the meat, chop, and return to the sauce. Toast buns, and serve the sloppied steak on the toasted buns.


  • Easy Cleanup
  • Try using a liner in your slow cooker for easier cleanup.

I tried this last night and it had great flavor. I did shred the meat and let it warm for about an hour before serving. The only other change I would make is taking the steak out, slicing it a...

We enjoyed this method for making a good flank steak BBQ sandiwch. While the sauce base was fairly good, it was too tomato-y, so I tweaked it based on my sloppy joe sauce recipe. I started wit...

Excellent recipe. Next time I'll increase the amount of steak in comparison to the sauce; otherwise came out perfectly!

I liked this using a beef flank steak instead of pulled pork.

I really liked the taste and the presentation....we usually eat our sloppy "whatevers" open faced. Only change I made was to drain most of the liquid out of the tomato sauce into a container (wh...

These were superb, I will definitely make it again,

I cut a flank steak in half to make this recipe as one of our entrées and 'Flank Steak a la Willyboy' from AR as our second entrée. This was good but really, really saucy. At the 4 hour mark, ...
