Chicken Tortilla Soup

While I love ordering chicken tortilla soup at any Mexican or southwestern restaurant, I know that none of them are keto friendly. This chicken tortilla soup is as close to the version I love, without the extra carbs. This low carb green enchilada chicken soup has some of the same flavors and is very easy to make.

Generally, masa (corn flour) is added to tortilla soup to give it that delicious corn flavor and thickness. Unfortunately, masa isn’t keto approved. So making keto chicken tortilla soup requires some adjustments.

In this recipe, I’ve left out the masa, but I’ve added keto tortillas, which give the soup a similar texture and satisfies that tortilla soup craving, without adding flour to the soup.

Ingredients You’ll Need

While this recipe calls for quite a few ingredients this soup is cooked in one pot as sort of a dump and go recipe. You will love how quick and easy it comes together.

For the soup:

  • Olive oil – Using olive oil will add healthy fats to the soup. You can use avocado oil or any other cooking oil as well.
  • Onion and garlic – You can use red or white onion for this recipe and 1 clove of freshly minced garlic.
  • Canned tomatoes
  • Chicken broth
  • Chicken breast – Cooked and shredded.
  • Herbs and spices – Cilantro, cumin, chili powder, paprika, and chipotle powder.
  • Optional garnish – Avocado and jalapeno peppers.

For the tortillas:

  • Almond flour – Finely ground almond flour.
  • Xanthan gum Xanthan gum is a popular food additive that is commonly used as a thickener. It has no flavor and is used in such small quantities that is doesn’t affect the taste of a recipe. It is very keto friendly as it has 0 net carbs. 
  • Baking powder
  • Garlic powder and salt
  • Apple cider vinegar
  • Egg

I use almond flour from WholesomeYum, which you can buy directly through that link (it’s our affiliate link). It’s the best almond flour I’ve found. It’s a blanched finely ground almond flour with a great texture and flavor, with just 2 grams or net carbs per serving.

How to Make Keto Chicken Tortilla Soup

This is an easy soup to make and doesn’t require hours of cooking. If you want to stew the soup for longer to develop flavors, you certainly can, but it’s not necessary.

Chicken Tortilla Soup

If you haven’t already cooked the chicken, start out by simmering 2 chicken breasts in a medium pot for 25 minutes, or until cooked through. Once cooled, shred the meat and set it aside.

Step One

Heat the olive oil in a soup pot over medium heat. Add the chopped onions and saute for 5 minutes. Add the garlic and saute for another minute. Be sure the heat isn’t high enough to burn the garlic.

Step Two

To the pot, add the tomatoes, chicken broth, shredded chicken, cilantro, and all of the spices. Stir to combine. Simmer the soup over medium heat for at least 10 minutes. You can simmer it for up to 2 hours to develop more flavor, if you want.

Step Three

Make the tortillas. Here is our full guide on how to make keto tortillas. It takes about 30 minutes from start to finish. This can be reduced to 20 minutes if you don’t rest the dough in the refrigerator, which is recommended, but not required.

Cook the tortillas until crispy, like tortilla chips. You can then cut each tortilla into chips to serve with the soup.

Step Four

Serve the soup with a tortilla, fresh avocado and chopped jalapenos, if you want to add some heat.

Garnish with avocado and jalapenos, if desired.

Frequently Asked Questions

Can I Freeze Chicken Tortilla Soup?

Yes, this soup can be frozen. It makes a great meal prep soup because of how well it reheats after being frozen. So you can make a large batch and divide it into servings to put in the freezer.

To reheat, just add the soup to a pot and cook over medium heat. You can also reheat in the microwave.

How Many Carbs Are In This Soup?

    This soup is DELICIOUS!! I used 1/2 tsp of cayenne pepper instead of chili powder and Chipotle powder just because cayenne pepper was what I had on hand. Also added cheese, avocado & used store bought tortilla chips for toppings! Made homemade chicken broth in the instant pot using Laura’s instant pot beef broth recipe and altering for chicken. I will be making these recipes again!
