Steak Fajitas Cooked in the Crock Pot

Nothing beats slowly simmered beef put into warm tortillas and garnished with your favorite tex-mex toppings. This is why this Crock Pot Steak Fajitas is what we ate for days last week. 

If you are as busy as a bee, and if you don’t mind juicy and tender meat that literally shreds itself, this is your kind of recipe. Unless you’re a vegetarian, then I guess this is not your kind of recipe. 😀 

But, if you love your meat, and your peppers, and your onions, AND fajitas!? Turn on the crockpot and git ‘er done! Also? Make sure you use your favorite tomato salsa because, essentially, we’re cooking and marinating the entire meat in said salsa. Thus, it better be good, or your favorite, you know?

The Crock Pot was one of the first major kitchen appliances that I bought, and I am in love with it. It solves all problems. I throw all the ingredients in the pot, turn it on, and 6 hours later, we have dinner! Like this awesome recipe for Crock Pot Lasagna! 😋

P.S. Did you know that in Spanish, the word fajita translates to “belt or “girdle” in English? Yep, it does! 😊 

Ingredients to Make Steak Fajitas

  • Flank steak 
  • yellow, onion

How To Make Steak Fajitas in the Slow Cooker

  • Start with cutting up the flank steak into six equal portions and place them in the slow cooker.
  • Next, cut up the onions and peppers and add those to the slow cooker. Then, pour in the tomato salsa and beef broth.
  • Add the fajita seasoning; stir and mix everything together.
  • Cover and cook on HIGH for 4 hours or on LOW for 6 hours.
  • When the steak fajitas are finished cooking, take out the flank steak and shred it or slice it, and stir back in the slow cooker. Serve on flour or corn tortillas, or serve the steak fajitas over rice.
  • You can use the slow cooker to keep food hot for up to 2 hours before serving.

These slow-cooked Beef Fajitas are great for that Saturday afternoon get-together when you don’t know when anyone is arriving, but you don’t want to be cooking when they get home. 

Toppings for Fajitas

  • salsa
  • sour cream
  • chopped salad
  • shredded or grated cheese
  • sliced jalapenos
  • chopped fresh cilantro
  • avocado slices

      How To Store Leftovers

      • Store leftovers in shallow containers and refrigerate them within two hours after cooking.
      • One of the best parts of your crock pot meal is the leftovers, but make sure you are storing them safely and eating them in a timely manner to reduce your risk of food poisoning. No one wants that. 😐 

      How To Freeze Fajitas? 

      • Store all leftovers in a freezer-safe glass container or large Ziploc freezer bags.
      • Label it and keep in the freezer for 2 months.
      • To defrost, completely thaw in the refrigerator before reheating.

          Do you recommend something else besides a tomato salsa?

          1. Katerina says:

            You can use any sauce you like. Some ideas off the top of my head would be a tomatillo (green) salsa, marinara, or pasta sauce. BBQ Sauce would add a different flavor profile, but it’s something you can consider.

          Great. I used London broil because that’s what I had. Ended up with shredded beef which suited me and my husband just fine!

            I’m glad you enjoyed it! Thank YOU! 🙂

          Hard pass!!! Very disappointed. Maybe with a skirt steak or a sirloin but Flank Steak doesn’t belong in fajitas. Wrong texture and wrong flavor for fajitas. Thank you for the try but being from Texas I would say this is far from being fajitas. My apologies for being brutally honest but I just felt like this idea would have been better with beans and ground beef and maybe some chorizo and made kind of a stew out of it.

            Agreed. I love fajitas, and this was a bit more like a stew or something.
