Low Carb Taco Bar with Nopales Guacamole
Jump to Recipe Print Recipe

Possibly the best thing about a taco bar, especially a low carb taco bar, is the ability for everyone to enjoy a taco (or two) personalized to their own taste. Because of this, taco bars are the perfect food choice for a weeknight dinner but can be easily adapted to a wedding or other large party. The recipe for a nopales guacamole is included below as one of the unique sides.

What’s So Special About a Taco Bar?

The best thing about taco bars is that there is literally something for everyone, whether you are on a special diet or just have picky eaters in your group. From various tortillas, meats, cheeses, vegetables and sauces the options are endless!

The restaurant world offers some unique ideas for taco bars that you might consider when designing your taco bar. On a recent trip to Denver, we ate at a wonderful little taco bar called Agave Taco Bar. The homemade tortillas ranged from simple corn tortillas to spinach-poblano tortillas to squid ink tortillas. The fillings were wonderful, including everything from pulled roasted duck to beef tongue, to home braised pork belly. Of course there were great cheeses of all kinds, Mexican spices and vegetables such as cactus leaves and tomatillos. 

If some of the more unique items (such as squid ink tortillas) are unavailable (or undesirable) to you, there are plenty of ways to design more classic taco bars. They can even be adapted to low carb diets! And because you will be familiar with everyone’s tastes, you can tailor the bar to individual preferences.

What Ingredients Work Best for a Slow Carb Taco Bar?

There are many taco bar ingredients that lend themselves to a slow carb or low carb diet. Here are some of my favorite options that would work well in a modified slow carb taco bar:

Meat & Fish:

  • Roast pork, cooked until tender in slow cooker
  • Catfish, lightly sautéed in oil and shredded
  • Chicken, roasted and shredded

Suggested Cheeses & Sauces:

  • Oaxaca cheese
  •  queso fresco cheese
  • sharp cheddar
  • fruit salsas (not always low carb)
  • chipotle salsa
  • tomatillo salsa
  • aioli (for fish tacos)
  • guacamole (see recipe below)

Suggested Low Carb Toppings:

  • sliced radishes
  • Raw onions or pickled onions
  • cabbage slaw
  • roasted poblano strips
  • roasted red peppers
  • refried black beans
  • cactus paddles, chopped

What About Chips, Shells and Tortillas?

Staying low carb with the fillings for a taco is relatively simple compared to trying to find low carb alternatives for the chips or tortillas in which to place the filling. Fortunately, there are many commercially available low carb tortillas now available. But depending on your time and willingness, you can make some tasty homemade alternatives.

Homemade Low Carb Tortilla Recipes

There were several recipes and videos on the internet for cauliflower tortillas that were all slightly different, so it did take a little messing around with to find the recipe that held together but was flexible enough to hold like a flour tortilla.

My recipe for Cauliflower Tortillas is a very slight adaptation from this one at   Similar versions with small modifications can be found at empowered sustenance and Tasty Alternative.

Low Carb Tortillas to Purchase

Siete tortillas- the almond flour tortillas are the lowest carb option I could find available on Amazon. We tried this brand when vacationing in Arizona and it was pretty good.

**TIP: If you don’t have the time or inclination to make tortillas from scratch, there are a number of low carb tortillas commercially available. Below is a list, which is by no means comprehensive. With a little searching, I’m sure you can find other brands too. However, here are some brands you can look for:

  • Mama Lupe Low Carb Tortillas
  • Mr. Tortilla Low-Carb Multigrain Tortillas
  • Tia Lupita Low Carb Cactus Corn Tortillas
  • La Banderita® Carb Counter / Whole Wheat Flour Tortillas
  • Mission, Flour Tortilla – Low Carb -Soft Taco

How to set up your taco bar

There is a logical order to setting up a taco bar so that people can make their tacos quickly and easily. The plates should be first in the assembly line, followed by any shells or wraps that people will need to place their fillings on. Low carb dieters may wish to forgo a wrap and prefer to pile their ingredients in a bowl, ala Chipotle, so make bowls available at the head of the line too.

Next lay out the bean, meat, fish, and cheese choices. Make sure that you have serving utensils in each choice so guests don’t need to steal from one ingredient to use in a different one, causing flavors to mix.

Adjacent to the meats/cheeses place the salsas. It is always nice to have at least one mild and one hot salsa choice. Finally, put out any additional topping choices such as jalapenos, guacamole, lettuce, pineapple, etc. At the end of the table place the napkins and any utensils so people are not burdened with holding these while trying to assemble their tacos.

Don’t Forget the Guacamole!

Guacamole is one of the main sides in Mexican cooking. Traditional guacamole is made using a mortar and pestle, but it’s just as easily made with a fork. Nopales (cactus paddles) are also very traditional Mexican fare and are sometimes a separate item on a taco bar – cooked and chopped or diced.

The following recipe is for a great, unique guacamole with the nopales mixed in, which adds a cool, creamy element to the taco bar. Buen provecho!

**Tip: Bear in mind that one ingredient that does not store well for later use is guacamole. You should endeavor to make your guacamole fresh, not too far in advance of the meal.

  • ½ cup chopped cactus paddle (optional) Fresh paddles will need the spines removed
  • 2-3 tsp olive oil divided
  • 1 avocado
  • 1 lime juiced
  • ½ tsp salt or to taste
  • 1-2 roma tomato diced
  • 1 jalapeno diced
  • 4 sprigs of cilantro


  • If you want to add cactus, buy a fresh cactus paddle, remove all the spines by running a spoon or knife along the front and back. Cut off the sides of the paddle and discard. Check the nopal paddle carefully to make sure all spines are removed and rinse thoroughly.
    A detailed description on removing thorns from nopales can be found here.
    Once thorns are removed, chop or dice to your preference.
    Then Heat oil in a large, nonstick skillet and add chopped cactus. Cook for about 10 minutes until cactus is cooked. Set aside to cool.
  • Peel and remove pit from avocado and add to a large bowl. Add the lime juice, olive oil and salt.
  • Dice (or chop) the tomato, jalapeno and cilantro. Add to bowl with the avocado and add the cooked cactus If using cactus. Slightly mash and mix all ingredients together. Place in the refrigerator to meld the flavors for about a half an hour before serving.


This recipe uses a raw nopal (cactus) paddle, but you can buy the cactus already cooked and chop it as finely as you prefer. 
If you prefer your guacamole less spicy, remove seeds from jalapeno before dicing.
