If you love chicken fajitas but are following a keto or low carb diet, I’ve got the perfect alternative for you-this Low Carb Chicken Fajita Soup! It has all the same delicious Mexican flavors without all the carbs from the tortillas!
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 crock pot.
- 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 taco seasoning since store-bought seasoning packets can 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 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 for 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).

Rosanne says
Can you freeze the remainder of this fajita soup.
Kasey says
I prefer not to freeze because the texture of heavy whipping cream, cream cheese, and cheeses can change when frozen.
Deborah says
I love this soup? Can I freeze the left overs?
James Cook says
This soup freezes well.Make a pot full then freeze for later.Can’t go wrong with this one.
BKraft says
Can this all be made in the crockpot?
Kasey says
Dairy products like heavy whipping cream, cream cheese, and cheese often break down in the crockpot and can become grainy.
Misty says
How much is a serving of soup?
Kasey says
The number of servings is listed at the top of the recipe card. I use that number and divide it evenly.
Erin says
So the nutrition is per serving?
Kasey says
Yes, it is per serving.
Tom says
Is there a substitute for the heavy whipping cream? Don’t have any. Sour cream possibly?
Kasey says
Not that I know of. Sour cream would totally change the taste.
KATRINA says
This recipe is yummy to my tummy! I boiled skinless chicken thighs and used the broth from the thighs. I couldn’t be more happier on how it turned out. Thanks for sharing.
Kasey says
So glad you enjoyed it.
Susie says
I totally love this soup recipe! I make it a couple times a month and freeze it 2 cups at a time. I love when I’m busy and think, “What can I have for lunch?” and remember I have soup in the freezer!! I like to use orange, red, green and yellow peppers because I love all the colors. Now I’ve said love three times so you know how much I LOVE this soup!
Kasey says
Hahahaha! I’m so glad you LOVE it!
Bethany Priester says
OMG! So delicious! I used the chili seasoning recipe provided. The only thing I did differently was to add a whole jalapeno because we like things spicy. This is a keeper!!
Kasey says
Perfect! So glad you loved it.
Cindi says
I made this soup today and it is wonderful!.
I also cook chicken and freeze bags of it. It is so helpful when cooking, if you already have the chicken done.
Kasey says
Fantastic! So glad you loved it. That sounds like a great idea.
