Easy Crockpot Beef Fajitas


One of the most popular recipes on my site right now is one of the newest – Easy Crockpot Chicken Fajitas by EaH writer, Rachael.

I’ve been wondering about a beef version and some of you have had that thought too.  So I decided to give it a try.  This could not be easier and it’s really delicious too.  The house smelled fantastic the whole time it cooked.

I used beef cut for Milanesa, which I found in Walmart.  It’s top round that’s been cut extra thin.  You could use other cuts of beef too, but I really liked this very thin beef for this dish.  I also used a packet of fajita seasoning instead of taco seasoning.

Here’s what you’ll need:  

I served the finished fajita filling in tortillas with shredded cheese.  Yum!

  1. Do you add any water or juice to the crock pot or is it cooking dry?

  2. I am planning on using this and the chicken fajita recipe for a party that I’m hosting. I will be having approximately 35 people. Can you give me any guidance on what your recipe serves? Have you ever done this for a large crowd?

    • Traci, If you do 3 lbs of meat and add more veggies too, it would probably serve around 10. I’ve never done a recipe like this one for that many people. You might be able to get away with doing 3 crockpots full and making it be enough. Especially, if you serve a lot of side dishes with it. ANd I’ve noticed that people tend to eat less when you serve on paper plates, probably because they are a bit smaller than a regular dinner plate.

  3. What size of crock pot did you use?

  4. D.Madewell says:

    I am curious if I am making the beef fajitas but only have taco seasoning on hand.. will that mess with the recipe much vs/the fajita seasoning?

  5. Are the veggies soggy after being cooked that long?

    • Natalie, they aren’t crisp after cooking. One idea would be leave the veggies out until 20 minutes before you’re ready to eat. Then lay them on top of the chicken to cook. That will leave them with more crisp to them.

  6. What would be a good side dish or two, to go along with the Chicken Fajitas?

    • Chips, salsa, guacamole, refried beans, corn and black bean salad, Mexican rice, tossed salad with tortilla strips and ranch dressing. How do those sound? Merry Christmas!

    I just put this together in the crock pot and have it all ready to go for tomorrow’s dinner. It looks like it will be good when it’s all done and it already smells good and it’s not even cooked. I’ll let you know what my family thinks!

  9. Is the beef dried out being in the crockpot that long.

    Sounds great. Thank you

  11. Do I stir this occasionally or just before serving??

  12. If I’m not adding the onions, will there be enough liquid or should I add water?

    Could this be done in a pressure cooker? It looks delicious!

  14. What type of beef do you use? Would appreciate suggestions for cuts that come out tender without being too pricey.
