    Why You'll Love Chicken Fajitas Soup (Crock Pot)

    In my husband's words: "Crockpot chicken fajitas soup is the BEST chicken soup I've ever eaten! It's the perfect mix of creamy broth with just the right amount of chicken, peppers, and onions. Can't go wrong with cheese in it either!" 🙂 -Kori

    Be sure to check out these three delicious Mexican-style chicken soups - easy and delicious Green Enchiladas Chicken Soup and Chicken Enchilada Soup (with red sauce). If you love tacos be sure to try this "souper" easy 7 Can Chicken Taco Soup! If you don't want soup, then you'll love Chicken Fajita Casserole.

    It's Tasty

    This soup is so tasty and full of zesty flavors. You really can customize the spice in this by changing from mild, medium, or hot salsa. This is one of my family's favorite soup recipes! I hope you enjoy it!

    The BEST Chicken Soup

    I have been making this soup for years. It's such a simple recipe to make in your slow cooker. I've served it to family and friends and it's always been a huge hit. It's very easy to double so you can serve to a crowd as well.

    It's Easy

    Really there is not too much to do other than cut your veggies, the rest is just dumping certain ingredients in at the beginning, and others at the end.

    Crockpot or Instant Pot Option

    Keto Soup Recipe

    This healthy soup recipe is low in carbs, has no added sugar, is gluten-free, and keto-friendly. If you wish to increase healthy fat in this recipe you can add more avocado oil, and more cheese, and top it with fresh avocado and sour cream.

    If you want to lower protein then you can use less chicken. Using four chicken thighs instead of six lowers the protein content to 24.3g per serving.

    Ingredients for Making Slow Cooker Fajita Soup

    Here are the ingredient and tools you'll need to make low-carb keto chicken fajita soup:

    Ingredients needed for making crockpot chicken fajita soup
    • Onion: use yellow or white onion
    • Bell Peppers: any color can be used, I like to use different colors so it's pretty!
    • Garlic
    • Boneless Skinless Chicken Thighs: chicken breast may also be used.
    • Fajita Seasoning: make your own seasoning mix, or use a packet. Taco seasoning may also be used.
    • Chicken Broth: stock or chicken broth is fine.
    • Chunky Salsa: use mild, medium, or hot - whichever you prefer.
    • Shredded Cheddar Cheese
    • Heavy Cream: half and half may also be used
    • Sour Cream: use regular or reduced fat
    • Salt and Pepper: to taste
    • Optional thickener: 1/2 tsp xanthan gum mixed with 1/2 tsp of olive oil, or 1 tablespoon cornstarch dissolved in 2 tablespoons of cold water or broth.

    Instant Pot Instructions

    1. Add onion, bell peppers, garlic, chicken thighs, broth, and fajita seasoning to the Instant Pot.
    2. Secure lid and cook on High pressure for 4 minutes. Quick-release pressure after the cooking cycle is complete.
    3. Remove the lid from the pot once pressure is released. Add salsa and cheddar cheese, stirring until melted.

    How to Serve Chicken Fajita Crockpot Soup

    Slow cooker chicken fajita soup is really a meal-in-one but if you're wanting a little variety, here are a few ideas on to serve it:

    Adjust seasoning to taste. Garnish with fresh cilantro or green onions.

    If you are a low-carb keto follower, make (or buy) cheese crisps and dip in the soup.

    Non-low carb followers will enjoy corn chips, tortilla chips, or even corn bread.

    A fresh green salad goes really well with the soup. Make an easy taco salad dressing by mixing salsa, sour cream, and a pinch of salt and pepper.

    Variations

    Here are some ideas to customize this slow cooker fajita soup or make substitutions:

    • Substitute chicken breast for chicken thighs.
    • Fire-roasted tomatoes or diced tomatoes with green chiles can be added in addition to or in place of soup.
    • Add more vegetables. Zucchini and mushrooms are delicious. Just add in step one and cook along with the chicken.
    • If you are not following a low carb or keto diet you can add drained and rinsed black beans, pinto beans, or a can of corn.
    • Add heat with sliced jalapenos or use a hot salsa.
    • Add a smoky taste by using a few drops of liquid smoke.
    • Use a different kind of cheese to mix up the flavor.

    FAQ's

    Can I make this soup in an Instant Pot?

    Yes! Instructions are above, but add all ingredients except the salsa, cheese, half and half, and soup. Cook on the High-pressure setting for 4 minutes. Allow pressure to release naturally. Remove the lid when pressure is released, and add remaining ingredients. Serve and enjoy!

    How can I lower the fat in this recipe?

    If you'd like to lower the fat in this recipe, use half and half or a lower-fat milk and a lower-fat sour cream. You can also use chicken breast instead of chicken thighs, and use less cheese.

    Is chicken fajita soup keto?

    Yes, this chicken fajita soup recipe is keto with only 6 net carbs, 22.9 grams fat, and 31.6 grams of protein.

    How can I add more fat to this recipe?

    Add 1 to 2 tablespoons of avocado oil, add additional cheese, and top with avocado and sour cream.

    How can I thicken my keto soup?

    An easy way to thicken soups when following a keto diet is to use xanthan gum. Use it sparingly, as a little goes a long way. Mix 1/4 to 1/2 tsp xanthan gum in a small bowl with a small amount of olive oil or avocado oil (1/2 to 1 tsp). Add the mixture to whatever you are trying to thicken.

    How to store it

    Let the soup cool, then transfer it to an air-tight container. Store in the refrigerator for up to 4 days.

    Can I freeze it?

    Yes, you can freeze this soup for up to 4 months. Be aware that when dairy is frozen it can separate and give it a slightly curdled look. This does not affect the taste. To remedy this, add a little cream and sour cream to the soup before re-heating.

      Made this recipe in my instant pot. Um... So yum. Cant wait to make it again!!!! The only thing I did "different" was no bell peppers. Also, I soaked a whole small onion (yellow, diced and over 1 heaping cup), the garlic, oil in the broth in frig. And I diced and sliced random bite sized pieces of chicken and also frozen that with the rest of the broth in a seperate container in the freezer. I food prepped it all Sunday and then made it Tuesday, so I pulled out the meat to the frig 24 hours before making it, I didnt know when i was going to be making it so this is why I froze it, I recommend not if your schedule and food prep allows. It was still a little frozen and stuck together, so I added 3 minutes to the total pressure cook. I dont like cooked bell peppers, so I skipped them entirely.
      Waited about 22 minutes before I decided to release the remainder of pressure, we were hungry, and the remaining released in about a second, so not much was left. It was perfect! Added the close to room temp cheese and salsa. Then room temp sour cream and half&half. Left our more salsa and sour cream, sliced avocado, cheese and chips to add on top if they wanted. It was a hit!!! Highly recommend!!!

      I'm getting ready to make this in crockpot. In the directions I do not find a direction regarding adding the taco seasoning, only salt. From photos it looks like you sprinkle it over chicken before addition liquid.

      Hi,
      Have you ever used chicken breast instead of thigh meat?

        January 27, 2022 at 9:20 am

        Yep! I've done it many times. Thighs add a little bit more richness to the soup (because they contain more fat), but it will still be very good! 🙂 Enjoy!

        Hello, yes it can cook in your crockpot on High for 3 to 4 hours until the chicken is done and vegetables are tender. Turn it down when you add the dairy though. I hope you enjoy! 🙂

      Does this soup freeze well?

        April 06, 2022 at 8:19 am

        Hi! You can, but a couple of thoughts. Dairy can often separate when frozen and since there is so much dairy in this recipe it does. Separation won't affect the taste though. If you choose to freeze the soup from the full recipe with dairy added, you can offset the separation by adding a little extra cream before reheating. You can also freeze the soup before adding the dairy products. Thaw in the refrigerator and warm in your crockpot when ready to serve. Add the dairy products (See recipe card) after the soup is warm. Hope that helps! Enjoy!

      This is so delicious! The only thing I did different was add 2 taco seasoning packets, 1 was spicy and 1 was low sodium instead of fajita seasoning. My salsa was medium and the flavor was excellent.

      Your print button isn’t working, keeps opening in a new window. Don’t know if it’s just because I’m on my iPad. Will be trying this as my husband and I really love homemade soups. Was hoping to be able to save it.

        Oh, sorry you're having troubles! I just checked and it seems to be working fine on all my devices. It should open another window with a print screen then you can select what view you want to print. Maybe that is what you're seeing? I hope you enjoy this soup - it's one of my absolute favorites - my husband's too! 🙂
