Today I have another slow cooker recipe for you – slow cooker steak fajitas. I am starting to fall back in love with my slow cooker. We had quite a fight a few years ago. But once I invested a little time into our relationship it has gotten much better.
Fajitas in general are a relatively easy recipe to make – all you need to do is cook up some meat, veggies, and throw in a tortilla. Although, if you don’t have time to be in the kitchen, prior to dinner, then making this slow cooker recipe might be a good solution for you.
This easy recipe, adapted from the Not Your Mother’s Slow Cooker Cookbook
To make this recipe even more busy mom friendly I turned it into a slow cooker freezer kit – which by the way is one of my new favorite things to do. When I was ready to cook it I just dumped it into the slow cooker frozen, turned it on, then 6 hours later it was done. Having these kits in the freezer makes life so much simpler.
Once the beef is cooked this recipe becomes very versatile. I prepared them traditionally in a tortilla but you can just as well serve them in a pita, as a sub, or on top of a pizza.
Slow Cooker Beef Fajitas
- ¾ cup of your favorite prepared salsa
- 1 tablespoon tomato paste
- 1 tablespoon olive oil
- 1 garlic clove, minced
- Juice of 1 lime
- 1 teaspoon freshly ground pepper
- ½ teaspoon salt
- 1 pound flank steak ( make sure silver skin and extra fat is trimmed off if needed)
- 1 large white onion, cut in half then thinly sliced
- 1 red bell pepper, sliced into strips
- 1 orange bell pepper, sliced into strips
- 1 yellow bell pepper, sliced into strips
- Avocado cream spread
- 1 avocado, mashed
- ¼ cup greek yogurt
- Juice of a ½ of lime
- Salt and pepper to taste
- Mix together, in a small bowl, salsa, tomato paste, olive oil, garlic, lime juice, pepper, and salt.
- Place flank steak into the bottom of the slow cooker then pour mixture on top. Lay the onion and peppers on top.
- Cook for 5 – 8 hours on low. **I used a 6 quart slow cooker and put mine in frozen. It was done at 6 hours. If I put it in thawed it would have been done probably at around 5 hours (or less). Depending on your slow cooker your time could vary.
- Remove steak from slow cooker and cut across the grain into thin slices.
- Mix together avocado, greek yogurt, salt, pepper, and lime.
- Divide steak, peppers and onions, and avocado spread among 6 tortillas. Roll up and serve warm.
Slow Cooker Freezer Kit Instructions
Complete step 1. Then put mixture and flank steak into a freezer bag, label, and freeze. Place onions and peppers in a separate freezer bag, label, and freeze. Keep both bags together in the freezer.
When ready to cook you can put this kit in the slow cooker frozen or thawed. Obviously, remove from bags first then continue with step 2. Again, all slow cookers are different so be aware of the cooking time.
Other Freezer Cooking Instructions
You can also cook this slow cooker recipe completely, cool, and then freeze into portions.

January 20, 2014 at 3:02 pmI love this! I do this with chicken instead, and it’s one of my favorite freezer meals. I have to try really hard not to just cook it the next day when I freeze it. I’ve been meaning to try it with flank steak. Your pic looks so yummy that now I HAVE to do the beef.

January 21, 2014 at 5:33 pmI am guessing the carbs would be a lot less without the tortillas. I plan on making this tomorrow minus tortillas

January 23, 2014 at 8:44 amAnother great recipe and I think I have all the ingredients which makes it really good!! Can you please tell me on average how many calories you calculate for the tortillas? Definitely going to make but may swap out tortillas for some veggies instead.

January 23, 2014 at 9:10 amWould it cook faster and be easier if the meat was sliced before putting into the slow cooker?

June 13, 2014 at 6:27 pmFantastic! Here’s a trick I picked up along the way when freezing the prep for a slow cooker dish. If you put the meat & sauce in a slow cooker liner bag before you place it in a freezer bag, it is so easy when you are ready to use it. Just put the liner bag in the slow cooker, add the veggies, which are much easier to remove from the freezer bag then the meat and sauce, and go! No chiseling necessary! Plus, you can use one freezer bag instead of two. Put the veggies in first and the liner bag in on top and seal the deal.

August 5, 2014 at 11:28 amI made this with a 2lb london broil, omitted the avocado cream, and used a FlatOut tortilla. The calorie count came out to 437/serving, including tortilla. I thought that might help some of you asking about calories. Also, this is delicious but 5hrs on low was too much for even 2lbs of meat. I think it wouldve been fine at 4. Keep an eye on your beef!
