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. 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
Yield: 5 – 6 Servings
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.
Directions
- Mix together the dry spices with a fork including the chili powder, cumin, coriander, salt and pepper.
- 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.
- 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.
- Turn the slow cooker onto HIGH and cook for 5 – 6 hours or until the steak can easily be shredded with two forks.
- Drain the meat and peppers well then serve with the recommended fajita “fixings” (listed above). Enjoy!

We just received our first grass-fed cow this weekend. I look forward to making your fajitas with our steak. :0) Slow-cooking is my favorite.
Ah! These sound delicious! I will definitely have to try these. Thanks for the recipe!
I’m always looking for easy and tasty crock pot recipes and this one sounds like a winner!
This looks wonderful and it is a dish my family would love. This is my first visit to yoursite so I took some time to browse through your earlier entries. I’m so glad I did that. I really like the food and recipes you share with your readers and I’ll definitely be back. I hope you have a great day. Blessings…Mary
I have a similar recipe that uses chicken and we LOVE it. Can’t wait to try this.
This looks very good!! Crockpots are the best! Healthy meals prepared in the morning and ready for dinner, makes life a little easier!! We like to use BRAGG’s liquid aminos instead of soy sauce!!
I have to say thank you! I found your blog about 3 weeks ago and cannot be more grateful! By bringing your family to a more healthy lifestyle you have begun to help me as well. I am allergic to artificial additives and preservatives, so your recipes allow me to feel like I eat more like the rest of the world! Thank you!
I’m always on the look out for recipes based on real “real food”. Thanks for sharing with the world and I’ll definitely be directing friends, family and customers to your site.
I made this recipe for dinner last night, and my husband and I both LOVED it! We just bought 1/4 of a grass-fed, organic cow, and this was the first recipe I made with our beef. The only thing I did different was that I didn’t have flank steak, so I used round steak. It was absolutely delicious on homemade tortillas. I know I’ll be making this again! Thanks so much for sharing!
I found you from Pinterest. I was definitely fascinated by the slow cooker fajitas! I need new slow cooker recipes that my whole family will enjoy and I know these will be a winner! Love your blog and can’t wait to look around more. I am a real food lover myself. Try to eat mostly organic and local and Grass Fed. It’s not always easy to find, but I do think it’s important for our health and our earth.

Keep up the slow cooker recipes! It’s winter. I like my slow cooker in the winter.
The recipe is awesome. So awesome, I want to slow cook all things now. I substituted NM Red Chile, added a poblano and forgot about the soy sauce part, and it turned out delicious.
These are so good! I made them this weekend and my whole family loved them. Definitely will be making this again
This recipe was soooo good!!! I didn’t use the slower cook, I just used my saute pan. Worked perfect! Made it under an hour. I have four kids and super hubby. All gave it a thumbs up!
Yum! My husband and I love making fajitas…and I love even more doing it in the crockpot! I will be making this for super bowl sunday. Thanks!
I made this tonight for the first time. LOVED it!!! Served it over rice (instead of in the tortilla). And, I didn’t drain it; just served with a slotted spoon.
Love the idea of serving it over rice with the sauce…thanks for sharing!

was wondering if it would be ok to do 9 hours on low…don’t want to dry it out
.
You could try that as an experiment…should probably work.
Just made this last night and it turned out WONDERFUL!! Whole family loved it and so incredibly easy!!! Thanks for the wonderful recipes.
Would it be okay to add FROZEN meat to the crockpot or should I defrost it first?
It should definitely be defrosted first.

Your recipes are sooooo amazingly delicious! Thank you! I made this tonight and used 2 pounds of round steak instead because there wasn’t a store in town that sells flank steak! It was still delicious! I do not have a tortilla press yet, but am looking into getting one! Thanks for sharing your knowledge and delicious recipes!
I’ve never made a slow cooker recipe without any kind of liquid inside of it. Do you need water or beef broth to make sure it doesn’t burn? Or is the soy sauce enough? This sounds awesome and I just didn’t want to ruin it!!
No liquid necessary!
Not sure if it was me or my meat…but it was tough. I bought the flank steak, as recommended, and I’ve never had flank steak before so maybe it was just a different texture. Oh and at 4 hours it was pulling apart so I didn’t cook it any longer…maybe that was the problem.
Oh and the Ezekial Tortiallas (sprouted), not the best taste
If the meat was tough (and especially since you took it out a little early) my guess would be it didn’t cook long enough. It just gets more tender the longer you cook it. And while Ezekial brand is a great “real food” alternative I agree I am not a big fan of the taste/texture of some of their products.
