Beef strips, peppers, and onions are slowly cooked with Mexican seasonings and a generous squeeze of lime to make these Slow Cooker Steak Fajitas one of the easiest crock-pot meals to make.
Several years ago, I ran across this fajita recipe on Andie Mitchell’s site, Can You Stay For Dinner? Her Slow Cooked Chili Steak Fajitas sounded too delicious not to try asap.
To make steak fajitas in the crock-pot, you simply add all the ingredients except the bell peppers into the slow cooker and let that simmer until the meat is tender.
Toss the peppers in just before serving and let them soften for about half an hour.
With just the right amount of heat for my taste, I have already made another version of these crockpot fajitas with chicken. All the spices can be adjusted to your preference.
My husband and kids all really enjoy both versions of the fajitas and they’ve become regular meals on our menu plan.
COOKING TIPS FOR CROCK-POT FAJITAS
The total cooking time for fajitas will vary based on your crockpot. I’ve made this several times and in different slow cookers.
The cooking time really does vary that much. The first time you make this, you’ll want to check the meat after it has cooked a few hours and turn off the heat before it is falling apart.
The thickness of the strips of beef will also affect cooking time. I like to slice the meat super thin, maybe 1/8-inch or so, and as a result, the meat will cook through in about 4 hours. If I go much past that, the meat begins to fall apart. Still delicious, but not the strips of steak that you’re aiming for here.
This recipe does double or triple nicely to feed more people. However, the cooking time will need to be adjusted for that. So, as noted above, check the meat to determine doneness.
EASY CROCK-POT DINNER RECIPES
For more easy dinners that can be made in the crock-pot, check out this Slow Cooker Beef Stroganoff and the Spicy Five Bean Chili that my boys request at least once a month all year round. Crockpot Orange Chicken and Crockpot Bourbon Chicken both sound excellent as well and I’m thinking they need to be added to my meal plan soon.
Kitchen Tip: I use this slow-cooker to make this recipe.

Gloria says
Love fajitas and these look amazing;)
Anna @ hiddenponies says
Fajitas are a huge favorite around here but I've never done them in the slow cooker – great idea, and these look perfectly juicy!
Chris says
I know that the steak would be tender but I think I would miss the crispy edges you get when you grill them. Then again, on a day like this Monday when it is going to rain all day long, the crock pot sounds like a good option.

I love fajitas, these look amazing.I bet the chicken ones will look as good as the beef ones do.

We just had flank steak last night for dinner. These sound amazing and I love a taco with flank steak. Some cuts of beef aren't great in tacos, but flank steak is perfect. The flavors here sound great – I want one of these now!

Chanel says
I made these over the weekend and they were amazing!! My daughter was in town visiting and she ate 4 servings over her stay and had me freeze 3 fajita bowls with rice to take home with her. I added another round of seasoning toward the end and also a small bit of brown sugar Splenda which took the flavors over the top.!! Can this same recipe be made with chicken breasts? I want to make again right away. So good! Thank you!!
Mary says
It should work nicely with chicken as well, Chanel. I’m so happy you like the fajitas!
Crystal Farrow says
The flavor is just out of this world good! It’s so easy and all of my vegetable hating kids love it! I have made this a couple of times so far, and always double the recipe easily in my crockpot. Thank you!
Mary Younkin says
I’m so happy to hear that you’re enjoying this recipe, Crystal!
Deb Galloway says
Do you add any liquid to
the steak and spices?
Mary Younkin says
Only the items listed in the recipe, Deb.
Christian Jellerson says
It’s a great recipe, simple but not lacking. My only question is what in the name of Zeus is a large medium onion? As the recipe compounds for additional servings this discrepency starts to add a whole lot of onion…
Mary Younkin says
haha, I have no idea what a large medium onion is. Thanks for catching that, Christian. It should be (1) medium onion, about 1 – 1 1/2 cups worth of thinly sliced onions.
April Young says
So fast to make and super delicious! Thank you!

I’m so glad that you liked the fajitas, April!
