Slow Cooker Low Carb Tacos Recipe

These Slow Cooker Low Carb Tacos let you enjoy Taco Tuesday without all the carbs!

Mexican food is a favorite around our house. But now that I’m trying to eat a few less carbs, I’m having to make some adjustments.

These Clean Eating Slow Cooker Low Carb Tacos let you enjoy tacos with far fewer carbs. Image shows the taco ingredients wrapped up in a lettuce wrap, open from the side so you can see inside.

I know. Low carb stuff is not a terribly popular discussion among many clean eaters. Particularly today. But the truth is, I’ve lost weight so far eating clean AND low carb and I’m not even counting calories. I say whatever gets you to healthy is what you should do, so I’m sticking to it and it’s working. Yay!

Most people know that a simple way to cut carbs with tacos is to sub the tortilla for a large leaf of lettuce which is what I’ve done here. It’s tasty, and you don’t feel like you are totally missing out. But what about the rest of the ingredients?

I’ve had to look at carbs a whole lot closer lately to help control my blood sugar so I had to go just a little further than the shell to make this truly low carb.

Here’s some general info I found:


Cherry tomatoes are just slightly lower in carbs by 1 gram per cup than regular chopped tomatoes.


Avocados are a healthy source of fat and fiber, but they do have carbs. Whether you make guacamole or just slice up the avocado, keep it to no more than about 1/4 cup. That amount of plain, mashed avocado is about 5 grams of carbs, give or take.


These are a little friendlier in carbs just because you typically won’t use as much when they are raw. At just under 3 carbs per 1/4 cup, it’s not a bad way to add flavor without upping the carb intake significantly.

Top these Clean Eating Slow Cooker Low Carb Tacos with the low carb toppings of your choice and enjoy!

  5. I like pulled pork! But I’d love to find some new recipes in your book! 😉

  6. I use the slow cooker a lot, its so easy and helps to keep the house cooler in the summer! We love the buffalo shredded chicken.

  7. Stephanie says:

    This might be a silly question, but if you cook chicken in the crockpot, should you thaw it first or toss it in while it’s frozen?

    1. The Gracious Pantry says:

      Stephanie – You should always thaw first.

  8. This may be silly but do you add any liquid to this recipe or do the juices from the chicken do the cooking?

    1. The Gracious Pantry says:

      Natasha – Not silly at all! Yes, the chicken will provide enough liquid as it cooks. So you don’t have to add any.

  9. Hey Tiff, awesome website. Seriously, props to you, lady!
    I can make this recipe ahead and then what I make in the crockpot, just throw in the freezer? Then grab the Lettus and avocado later the day I want to heat it up? I just want to make sure because I’ve had bad experiences with freezer meals in the past, lol, live and learn.

    1. The Gracious Pantry says:

      Ren – Sure can! The important thing is how you wrap it to freeze it. Make sure whatever container you use is air-tight.

  10. This is exactly what I needed – a low carb, clean option. There are 3 diabetics in my home and finding healthy, low carb meals is a challenge. Thank you!!!!

      Susan – My pleasure! I have a low carb section on my blog here (see the recipe index) and there will be more coming because that’s pretty much how I eat these days. 🙂
