Chicken fajita soup is one of my family’s favorites. I first made it last winter when we were remodeling our kitchen. I was limited with my cooking appliances, but was determined to stay keto throughout the process. Chicken fajita soup became a regular in the meal plan rotation. This soup requires a crock pot or instant pot. You can also opt to cook this on the stove.

This is a very hearty fat filled soup that is great for a cold day! It’s got a little bit of a kick to it. Feel free to go spicier if you want by adding some hotter peppers. This would be great with zoodles in it as well. Play around with what you add to it. If you change it up, I’d love to hear what you did. I love to tweak recipes to make them different to change things up.

Make sure to use a clean taco seasoning or you can make your own with this recipe.
