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!
Ingredients
- 1 large onion, sliced
- 3 bell peppers in variety of colors
- 1 1/2 - 2 lbs. thin sliced beef, cut in strips
- 1 packet fajita seasoning
Instructions
- Place onions and peppers in crockpot.
- Place sliced beef on top of peppers and onions.
- Sprinkle fajita seasoning over beef.
- Cook on high for 5-6 hours or low for 7-8 hours.
- Serve in tortillas with any fixings you like.











Do you add any water or juice to the crock pot or is it cooking dry?
Lindsey, you don’t need any water. The onions and chicken create enough liquid.
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.
