Recipe: Slow Cooker Flank Steak Fajitas

Based on the popularity of my other crock pot “real food” recipes I think you guys will love this one, too. Slow cookers are great for entertaining because you can easily get all the work done in advance and have your house smelling amazing when guests arrive (we use this basic, inexpensive slow cooker). I just made these fajitas myself the other day and my daughters kept asking me “What smells so good??” They couldn’t wait to dig in and if you make the tortillas in advance it will just take some grated cheese, sour cream, and cilantro (plus any other fixings you like on your fajitas), and your feast will be ready in no time. I am getting hungry just talking about it. But don’t take my word for it…you must try it for yourself!

Slow Cooker Flank Steak Fajitas
Serves: 5-6
 
Ingredients
  • 1 ½ lbs flank steak, preferably grass fed (we buy ours from Baucom’s Best at the Matthews Farmers’ Market)
  • 1 ½ teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon coriander
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 2 tablespoons soy sauce, preferably the low-sodium variety
  • 1 jalapeno pepper, seeded and chopped
  • 2 cloves garlic, minced
  • 4 – 5 bell peppers, any color
  • 1 onion
Other fajita fixings:
  • Whole-wheat tortillas, grated cheese, fresh sliced avocado, cilantro, lime slices, fresh spinach leaves, sour cream, hot peppers, etc.
Instructions
  1. Mix together the dry spices with a fork including the chili powder, cumin, coriander, salt and pepper.
  2. Rub the spice mixture over all sides of the flank steak and place it in the bottom of the slow cooker. Sprinkle the soy sauce on top.
  3. Top the flank steak with the diced jalapeno and minced garlic. Slice the bell peppers and onion and throw those on top of the steak as well.
  4. Turn the slow cooker onto HIGH and cook for 5 – 6 hours or until the steak can easily be shredded with two forks.
  5. Drain the meat and peppers well then serve with the recommended fajita “fixings” (listed above).
    Enjoy!

    I’m going to try this but I don’t have organic, grass fed flank steak avaialble. Can I use top sirloin?

      Round steak is a good option.

    • Amy Taylor (comment moderator) |

      Hi Kelly. Sirloin should work, too. ~Amy

    Has anyone made this and frozen part of it for future meals? I never know what is ok to freeze and what isn’t… am afraid the peppers would become too mushy? Thoughts?

    • Amy Taylor (comment moderator) |

      Hi there. You can definitely freeze this. It may effect the texture of the peppers somewhat but they are already very soft from cooking. ~Amy

    Could this work with chicken thighs?

    • Amy Taylor (comment moderator) |

      Hi Melissa. That’s not something we have tried so it would be an experiment. ;)

    I have made this recipe several times and it’s always a huge hit! Tomorrow I plan to double the recipe and am wondering if I need to increase the amount of time on high it spends in the slow cooker? Thanks!

      Hi Kristen. We are not usually able to respond to recipe questions in real time. How did it turn out?

    Hi! I’ve bought all the ingredients to make this 2-3 times…then couldn’t find flank steak. We recently bought 1/4 of a grass-fed cow. Would arm steak, sirloin steak, or round steak work in place of flank steak? Just looking at my beef inventory. :) (I also have some chuck or rump roasts.)

  8. Amy Taylor (comment moderator) |

    Hi Elissa. You could use a chuck or round roast.

    I decided it was time to post a review since this is such a regular recipe in our house! We all love it here and it is by far one of my favorite slow cooker recipes. I just wanted to mention that I have occasionally used bison sirloin steaks for this in and it turned out beautifully!
