You'll Love Chicken Fajitas Soup
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
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.
You could also add diced jalapeno, or hot sauce to kick up the heat as well! I have a tendency to keep things on the mild side so that everyone in my house will eat. Those who like it spicy can zest it up when they eat.
I love slow cooker/crockpot recipes. They are perfect when you are a busy working person such as myself. I am sure I repeat myself a lot, but a slow cooker is a lifesaver for me while working full time and raising a family. It is fuss-free!
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.
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.
Instant Pot Soup
This chicken fajita soup can be made in your InstantPot/pressure cooker. Instructions below! 🙂

How to Serve
Crock Pot Chicken fajita soup is really a meal in a bowl but if you're wanting a little variety here are a few ideas on what to serve this soup:
- If you are a low carb keto following make (or buy) cheese crips and dip in the soup.
- Non-low carb followers will enjoy corn chips, tortilla chips, or even corn bread.

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.

Can I freeze this soup?

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.
seekinggoodeats says
You are so right! Thank you for catching that!! Typo on my part. Add the taco seasoning in with the chicken. I added it to the instructions! Enjoy the soup! 🙂
