Yes, it’s a thing and to be honest, I was a little skeptical at first. I wasn’t sure how it would turn out but I had to try it out because as the weather starts to dip into the 5o’s and even in lower when w-w-winter rolls around… the thought of fajitas via not leaving the comfort and coziness of my kitchen, and let’s be real, pajamas is so very appealing.

So I did it. I loaded up my slow cooker with 5 EASY ingredients and set the heat to low and tried real hard to forget it. It was difficult because as the day went on and the aroma started circulating throughout my home, I was anxious to wrap those beef, onions and peppers in warm, soft tortillas and shovel them into my face.


I purchased a 2-1/2 pound london broil, sliced it into 1-1/2 inch strips. Next I sliced up a large white onion and a large red and green bell pepper. For the salsa, I used this salsa recipe, but this one would work just as well and I always, always have homemade fajita seasoning on hand.


First I poured 2 cups of salsa into my slow cooker.


Then I added in the beef and vegetables.


Sprinkled in the fajita seasoning…


…and tossed to combine.


Cover, set on low and let the slow cooker do its thing.


5 to 6 hours later, dinner was done.

So I warmed up tortillas and stuffed them full of steak, onions and peppers THEN I topped them with guacamole, sour cream and some cilantro.

Serve with a side of beer. 😉

    I just made your recipe tonight, soooooo incredibly tasty! I made it with store bought salsa and fajita seasoning…this could not have been an easier recipe to execute and the result was delicious! Next time I will try making your salsa/seasoning! 🙂
