Slow Cooker Steak Fajitas
Over the last 18 months, I have become seriously addicted to my slow cooker. Prior to that, the only thing I really used it for was to make our favorite beer and brown sugar kielbasa and sauerkraut, but last January I started to experiment with different recipes and I even used it to make candy! While I discovered the most amazing mac and cheese recipe in the process, I still think the best things to make in the slow cooker are meat-centric recipes. The low and slow cooking results in meat that is falling-apart tender and that has tons of flavor.
A couple of Sundays ago, my aunt and cousin came over to visit Joseph and I wanted to have something ready to eat. I also wanted to spend approximately zero time in the kitchen, so I immediately planned on making something in the slow cooker. My husband suggested fajitas as something different, and they turned out phenomenal!
I’ve since made this recipe twice and I’ve used both flank steak and a boneless chuck roast… each one turned out great, so feel free to shop around and see what’s on sale or looks the best at your local grocery store. The method is very similar to the one I used for the slow cooker bbq ribs – you hit the meat with a flavorful spice rub and place it in the slow cooker, then cover it with sliced onions and peppers. A small amount of soy sauce is added to the bottom and that’s it! The vegetables and the meat product a ton of liquid, so nothing more is needed for the cooking process.
When it’s finished cooking, the meat just falls apart and is incredibly easy to shred. I served these on flour tortillas with salsa, shredded cheese and sour cream… some Mexican rice, avocado and cilantro would also be great toppings.

Can you use chuck steak for this recipe ?
About how many fajitas does this make?
Have you used instant pot with this recipe?
Hi Frank, I have not.
Just put this in the crock for tonight! I used top sirloin & sliced it w yellow peppers & onions. Also no soy sauce so threw a bit of old chop house marinade on the bottom. Dry rub of salt, pepper, cumin, Ca chili pepper, turmeric, & red pepper flakes (it’s all I had). Fingers crossed!!! Smells great already!
Yum! I made this recipe today, and YUMMY! The house smelled delicious all day, and my husband and teenage son loved them so much! Much better than eating out. Thanks for the delicious idea!
Hi! I was so excited to try this recipe. I got all of the ingredients… And about 3 hours in (on high), my chuck roast is not even remotely tender and almost cooked the whole way through. It’s so tough. ? What did I do wrong?
On a side note- it smells So delicious!!!
Hi Sheryl, I would perhaps keep cooking. Most times the meat is done cooking before the slow cooker time is up, but gets more tender. I personally only like cooking meat on low in a slow cooker – I think it comes out exponentially better even though it will still cook fine on high.
Made it this past weekend. It was a hit!. We didn’t have tortillas, but everyone was just eating out of the container I put it in. I made a sandwich with mine. Very tasty.
Those fajitas look tasty!
Could you try these with chicken? I do not eat beef typically but these do sound great… just wondering how the spice rub would turn out on chicken as opposed to beef… still sounds like it would be fine. Also, your photos of Joseph are to die for. I show my mom every week and we coo over them. Congratulations again on him and happy belated b-day!!
Hi Angela, I think this would absolutely work for chicken, no need to alter anything. Thank you also for the birthday wishes and kind words :)
Have you tried with chicken?
Did you ever try this with chicken? If so, what were the results? Thank you!
Hi Carolyn, I haven’t made this with chicken, but I definitely think it would work!
Hmmm what do you think of half chicken and half steak? Would you cut the chicken before or put whole breasts in? Thoughts on sides?
I would do whole breasts for the chicken. For sides I always like to do Mexican rice and guac for fajitas!
I love high flavor, low effort dishes. This is a terrific idea, using the slow cooker!

I need to make these! They look fabulous!
have a chuck roast in freezer so will make this soon – One thing, will only put part of onion and peppers in with meat. Feel they will get too done; so will sautéed the bulk of them when the meat is done for more texture In the fajitas
“Drain the beef and vegetable mixer” – uh, did you mean mixture? I think this is the first typo I’ve seen on your site. Maybe mommy-brain? Thanks for the recipe!
These fajitas look fabulous! Anything I can put avocado and sour cream on is fine by me. :) Pinned to try!
I love you!! LOL!! Can’t wait to try it.
I was looking for something different to make this week, now I’ve found it, thank you! Do you have a good recipe for Mexican rice? I can’t seem to find one I like
Hi Nicole, Mexican rice is also on my list… I’ll be sure to post as soon as I discover a great recipe!
These look super. I love anything I can do in the crockpot. Nice to have something new to try. Thanks!
Are the onions and peppers that are cooked with the meat served inside the tortilla? I know with your BBQ recipe the vegetables were thrown away. This looks delicious and I can’t wait to try them.
Thanks!
Hi Marla, Yes, traditional fajitas are served with onions and peppers, so they are included.
I’ve always made fajitas on the stove – never in the crockpot. Brilliant idea! Pinning :)
I love love LOVE your beer and brown sugar kielbasa recipe! We aren’t fans of peppers and onions in our house, but I will probably try this meat and spice combination soon. Absolutely adore my slow cooker!
These fajitas would be great to serve for any meal or buffet style dinner party. I love the idea of using the crock-pot to cook the meat. It’s less of a mess to clean up later on!
