How to make low carb chicken fajita soup

I love experimenting with new low-carb/keto recipes, especially when they are easy, and my entire family enjoys the finished product- like my Queso Soup recipe. So, I thought, why not change out the ground beef for some shredded chicken and add some Mexican spices to the mix! The result is a deliciously creamy, flavorful soup that is high in protein and low in carbs!

Chicken Fajita Soup Ingredients:

Cooking and shredding your chicken is what takes the longest, so if you have your chicken pre-shredded and ready to go, this recipe is super quick!

  • Chicken breasts- I will make my shredded chicken using my slow cooker in advance in bulk. This speeds this recipe up big time!
  • Chicken broth– This is the base of the soup and adds lots of flavors. It is also used to cook your chicken in your crockpot.
  • Green peppers, onions, garlic– Low carb veggies give this fajita soup nutrients and lots of added flavor!
  • Cream cheese, heavy cream, butter- These fats will add richness to your soup as well as creaminess.
  • Taco seasoning- I like to use my homemade keto seasoning since store-bought seasoning packets contain some non-keto ingredients.

Steps for making your chicken fajita soup:

Step 1: I begin this recipe by preparing the chicken so it is easy to shred later. I add boneless skinless chicken breasts to my slow cooker. It isn’t necessary to make it this way; it just makes my life easier around dinner time to have the chicken already cooked. Also, if you prefer a different cut of chicken, feel free to make substitutions that best suit your needs. You could also use a rotisserie chicken if you like!

Step 2: Saute the onion and bell peppers in butter to bring out the incredible flavor in your chicken fajita soup.

Step 3: Add in some homemade taco seasoning if you are following a strict keto diet. I like to make my seasoning in bulk and keep it in my pantry.

Step 4: Once all the ingredients are in your pot, simmer on low so that the cream cheese melts completely and that all of the different spices and flavors are infused together.

Step 5: Garnish with more shredded cheese and freshly chopped cilantro leaves! Serve hot!

Other chicken fajita soup toppings

Toppings are everything, so feel free to have fun topping your fajita soup! Make sure you keep your toppings low in carbs and keto-friendly! Here are some toppings I like to add to my soup:

  • sliced jalapenos
  • a dollop of sour cream
  • guacamole or fresh avocado slices
  • more diced tomatoes
  • freshly chopped cilantro
  • more shredded cheese
  • freshly chopped green onions
  • sliced black olives
  • lime wedges

How to get this fajita soup on the table quicker!

If you are super busy and do not have time to wait for your chicken to cook, I suggest you do one of two things.

1. Speed up the process by purchasing a rotisserie chicken from the food store. The chicken is already cooked, so all you need to do is cut off the breasts and legs and shred/chop that up to add to your soup. This will cut your cooking time by more than half!

2. Cook shredded chicken in advance in bulk. Then portion it out into one pound baggies and freeze them. This way, you can quickly defrost your chicken a few hours or the night prior and have it ready to go! This saves you lots of money, too, and can be used for many other shredded chicken recipes like my Keto Buffalo Chicken Casserole (w/ Cauliflower). How to make crockpot shredded chicken is a life-saver to save time!

Variations to this Easy Keto Soup Recipe:

  • Instead of 3 fresh garlic cloves, use 1 1/2 teaspoon of garlic powder
  • Substitute the fresh onion for 1 tablespoon onion powder
  • Add celery, cauliflower rice, spinach, or kale to make the soup a bit more hearty

Is this Recipe for Low Carb Chicken Fajita Soup Dairy-Free?

Often get asked about dairy-free keto recipes. As is, this recipe is not dairy-free as it contains several ingredients such as butter, cream cheese, and heavy whipping cream that are all dairy products. There are dairy-free options of cream cheese that I have seen at the grocery store. Many people sub sugar-free coconut cream made from coconut milk for heavy whipping cream and coconut oil can be subbed for butter. Personally, I haven’t tried any of these substations and cannot give a personal recommendation of how it would taste, but I did want to offer dairy-free options.

How to Store this Keto Chicken Soup Recipe:

It can be stored in the refrigerator in an airtight container for 3-5 days. It can be frozen in a freezer-safe container, but the soup’s texture may change when it thaws due to the high dairy content.

    Very flavorful! I even made your taco seasoning, which is a keeper too! I had to make mine dairy-free (vio life cream cheese), and it was still wonderful! I’ve had a hard time transitioning to fake dairy options in soups, but this recipe made that transition easy.

    1. So glad it worked for you Amiee. Allergies can be hard to cook around. Glad this one made that transition a little easier!

    1. Hi! The number of servings of each recipe is located at the top of the recipe card. I simply divide it evenly by that number.

    I made this for my family last night and everyone loved it! I was anticipating a large amount of leftovers, as there are only 3 people in my family, but we ate all of it. I can’t wait to make this again. It is definitely a new family favorite. Thank you!

    1. Awe, so glad you loved it, Sonya! Thanks for letting me know and leaving a review.

    Hi – is there a reason not to use salsa instead of diced tomatoes? Or maybe half diced tomatoes, half salsa? Sometimes salsa can add an extra layer of flavor.

    1. Hey Kellianne, great question. I am a big fan of using Rotel (diced tomatoes and green chilies). This is a go to in a lot of my recipes. I think you would be fine using salsa if that is your preference. I haven’t used it so I can’t say if the flavor profile is much different but it should be great.

    Made this tonight. I just through everything in the crockpot & let it cook all day. Shredded the chicken when I was able to shred with forks. It was delicious!!

    1. So glad you loved it! I LOVE slow cooker meals!! AS a busy wife, mom, home school teacher, and business owner I need all the help I can get. The slow cooker is one of those helpers.
