Nothing beats slowly simmered beef fajitas put into warm tortillas and garnished with your favorite Tex-Mex toppings. This is why these slow cooked steak fajitas were on repeat at our house all summer long. Taco Tuesdays and Fajita Fridays is how we roll.

If you are as busy as a bee and don’t mind juicy and tender fajita meat that practically shreds itself, this is your kind of beef fajita recipe. Unless you’re a vegetarian, in which case, this might not be your dish. lol 😁

But if you love your meat, peppers, onions, and fajitas, turn on the crockpot and git ‘er done! Also, make sure to use your favorite tomato salsa because we’re marinating the entire beef fajitas in the crockpot in that salsa. It better be good or your favorite, you know?

Ingredients You’ll Need

To make the most flavorful slow cooked steak fajitas, you’ll need a few simple ingredients that come together to create magic in your crockpot. These ingredients will ensure that your beef fajitas turn out juicy, tender, and packed with Tex-Mex goodness

  • Flank Steak: You can substitute with skirt steak if preferred.
  • Yellow Onion: White onions can be used as a substitute.
  • Red Bell Pepper & Green Bell Pepper: Offers a sweet taste and tender texture. You can use any color bell pepper. For a spicier version, chop up a jalapeño and mix it in with the other peppers.

        Equipment

        Notes

        • Sear the meat: For added depth of flavor, sear the fajita meat in a hot skillet before placing it in the slow cooker. This step caramelizes the surface and locks in the juices.
        • Make extra for leftovers: These fajitas taste great the next day. Make a larger batch and enjoy easy meals throughout the week.
        • Add citrus: Squeeze some fresh lime juice over the fajitas just before serving. The acidity brightens up the flavors and adds a fresh note.
        • Steak options: Skirt steak or flank steak are the two best choices for steak fajitas.
        • Fajitas toppings: Sour cream, shredded cheese, shredded lettuce, sliced jalapenos, sliced avocado, salsa, etc…

          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! ๐Ÿ™‚

          Hard pass!!! Very disappointed. Maybe with a skirt steak or a sirloin but Flank Steak doesnโ€™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.
