I don’t know about you but slow cooker meals have a special place in my heart. Especially on those busy weeknights when everyone has somewhere to be and you have just a little time to get dinner on the table and eat dinner as a family. 

Tacos are normally an easy family dinner to throw together, but sometimes doesn’t quite hit the spot. Well, you will not be saying that with the DELICIOUS slow cooker steak tacos. It is packed with flavor, and so simple to put together you would have thought you were in the kitchen over the stove all afternoon.

For this recipe, you can use your favorite salsa from the grocery store, or you even make your own! Once I learned that making your own salsa isn’t difficult, it was a game-changer. Take a look at this easy homemade salsa recipe from Cooking Classy!

Be sure to have these items for this easy dinner recipe:

  • Slow cooker
  • Nonstick cooking spray
  • Blender (THIS is such a powerful one)
  • Slotted spoon (THIS one works great!)

Ready? Let’s start preparing this flank steak recipe!

For this recipe, start by getting your slow cooker out and spraying the inside with your nonstick cooking spray. 

Then, take the flank steak and place it into the bottom of the slow cooker. 

Next, you are going to pour the jar of salsa, diced tomatoes (not drained), cumin, and the chili powder on top of the steak in the slow cooker.

Stir everything together until it is all mixed together well, then turn the slow cooker on and cook the steak on low for 6-8 hours or on high for 3-4 hours. 

While that cooks it is time to make the chipotle aioli for the tacos. 

Get out your blender and add in the mayonnaise, chopped chipotle chiles, fresh cilantro, minced garlic, cumin, fresh lime juice, and salt and pepper to your liking. 

After you do that, turn the blender on and blend everything together until it becomes a smooth sauce and then store it in an airtight container in the fridge for later. 

When the meat is completely done cooking, mix everything together shredding the steak as you go. 

Then, scoop the meat into the flour or corn tortilla shells and top it off with your favorite toppings and drizzle the chipotle aioli over top!

  1. This was so good, especially the sauce! It's definitely going into my recipe box. I didn't think the aioli was too spicy at all. My 3 year old ate it. The only change I made was using stew meat instead of flank steak. The leftover meat was great in breakfast burritos the next morning!
  2. Thank you for sharing this delicious recipe ! I have an old Rival Crockpot that has an earthenware insert and it took 6 1/2 hours on high to cook this. Absolutely delicious ! Makes great Quesadillas next day and all you have to do is add shredded cheese - makes for a quick easy lunch !
  3. This tasted great! But mine didn't look anything like the picture. The meat looked grey due to basically boiling in the juice from the salsa and diced tomatoes. Did you drain the tomatoes? How did you get yours nice and brown? It was really delicious and tender!

    I pinned this recipe the day you posted it through Bloglovin. I just wanted you to know that I get email notices when someone repins my pins. This recipe has been repinned just from my account 596 times and liked about 60 times. I just thought you'd like to know that. Love, In Christ, Colleen Smith

    I have been reading your blog and using your recipes for close to a year now...thank you so much! I love all of the slow cooker meals and the easy (delicious) desserts. I tried this recipe last week and it was a winner; my husband and 3 kids (ages 8, 6, and 3) loved it. The meat was really good but I think the sauce made it extra delicious.

    I made this tonight, amazing!!! Instead of using the cumin/chili powder I used half a taco packet, delicious! The sauce is to die for, lime juice gives it the perfect balance. Next time I may add some bell peppers for the last hour or so to make it more veggie filled! Yumola!
  7. Just wanted to say thanks for sharing this recipe.I made this last week with some modifications but my family loved it!! I didn't use flank steak, I had thinly cut beef (bulgogi choice cut) and I baked the meat because I didn't have enough time to use the slow cooker. After reading a few comments, I decided against making the chipotle aioli, my kids are picky when it comes to sauces and I just used sour cream and the rest of the salsa. I added black beans and corn to the tacos as well. The meat came out tender and full of flavor. The tacos were filling yet light. There was enough for everyone to have seconds so next time I will just have to make a larger batch!
  8. I used the recipe magic button for the nutrition, and it said for 1 serving it has 1436 calories...I hope this is somehow calculating this wrong? :) I would love it we could save your recipes to ziplist too - any chance of that happening? Thank you~
  9. I used a thinly sliced London broil since it was on sale. It cooked in 5 hours on low and I used a slotted spoon to serve as there was a lot of liquid. The chipolte mayo was very good . Served with all the usual toppings and hot sauce for those who needed it. Good reviews from the family, will definitely make again! Thanks!

    Hello, If i wanted to make this for a freezer dump meal, should I cook the meat first, or put everything into a bag raw to cook later? Will the aioli freeze well or last a few weeks in the fridge so that is one less step the new mom has to do?
    • Camille (Six Sisters Stuff)
      Hi Jessica! Congrats on being a new mom!! It's the best job in the world! :) To make this a freezer meal, I would recommend just dumping all the ingredients into a gallon-sized freezer bag (raw meat and all), then stick it in the freezer. When you are ready to use it, remove the bag from the freezer and place in the fridge for 24 hours to allow it to thaw. Then dump it all in the crock pot and cook as directed. :) As far as the aioli, I have not had much luck freezing mayo-based sauces - they tend to get clumpy and weird when you thaw them. I think that you could make it a week or two in advance and keep it in the fridge, but I wouldn't feel good about much longer than that. I hope this helps!
  11. I am so confused and am scared to try this. You state right at the beginning of your post that your husband was appalled at this recipe. That means he was horrified and didn’t like it. Can I ask what he didn’t like about it? I have 2 very picky eaters and it’s a chore in itself to find things they like to eat. Just curious what he didn’t like. I just want to pick the right steak taco recipe to try in the crockpot. Please advise when you get a free moment.
