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
  • 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.
  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).
We recommend organic ingredients when feasible.

      I didn’t realize I was going to make this until last minute so I didn’t have time to slow cook it. Instead I cut up the grass fed steak (don’t remember what cut I picked up, it was marbeled without a bone), doubled the “sauce” and let it marinade in the fridge for about an hour. I cut up the onions and peppers and sauteed them in some unsalted grass fed butter and then added the meat and mixed it well (and it seasoned the veggies to perfection without any additional seasoning needed). We have a local place that gets fresh 4 ingredient tortillas so I served it on those. I used the tomatillo salsa from your website with some organic sour cream and Daiya cheese and my kids inhaled it and my super picky husband said it was beyond delicious. Thank you for all your hard work and time you put into this website. It is my first go to when I need any type of recipe.

      Do I need to add any liquid to this recipe?
