My low carb journey has begun. I first thought eating a low carb diet would be impossible for a bread and pastry loving girl like myself, but so far so good. Preparing delicious recipes like this Slow Cooker Chicken Fajita Soup is certainly making it easier. I don’t feel like I am missing anything when I eat this flavorful soup.
While I will no doubt still enjoy an occasional piece of my favorite Texas Turtle Sheet Cake or a bite (or two or three) of Chocolate Mousse, I think I will be quite satisfied eating low carb recipes like this one. Many thanks to McCormick for sponsoring this post and providing samples of their new McCormick Skillet Sauces which inspired this recipe.
This Chicken Fajita Soup is so easy to make in the slow cooker, and tastes great the next day. If you like fajitas you will enjoy this soup. It has all the same great flavors, minus the tortillas. If you are not on a diet like myself, you can load this up with toppings like avocado, shredded cheese, black olives, sour cream, and tortilla strips. The possibilities are endless. But if you are on a diet, no worries, because it’s delicious all on it’s own.
Low Carb Slow Cooker Chicken Fajita Soup
Ingredients:
3 boneless, skinless chicken breasts
32 oz. chicken stock
1 (14.5 oz.) can diced tomatoes
1 medium yellow pepper, diced
1 medium red pepper, diced
1 medium onion, diced
2 cloves garlic, minced
6 oz. mushrooms, thinly sliced
1 (8 oz.) package McCormick Taco with Chipotle & Garlic Skillet Sauce
1 tbs. season salt
2 tbs. fresh cilantro, chopped
Pro Tip: Slow Cooker liners make clean up a breeze. I recommend them to anyone. I mean, the whole point of a slow cooker is the convenience. You can get these for a steal.
Directions:
Except for the fresh cilantro, add all ingredients to the slow cooker. Cover and cook on low for 6 hours.
Using two forks, shred the chicken breasts. Gently stir in fresh cilantro, cover, and continue cooking for an additional hour.
This recipe makes a lot of soup, about 14 cups. Don’t you love how simple this recipe is? Enjoy!

thanks for the recipe. I love soup. I got lentil soup in my crockpot right now so Im going to make this one tomorrow
That looks amazing. If only I still ate meat. I can tell it was delish
Yum, this looks amazing! & I love cooking in my slow cooker.
With it being so cold up here in the New England states my family has been asking for soup more often. I had just about run out of ideas then I saw this. I think they will love it. We eat chicken fajitas often.
I may be drooling. This looks so good! Perfect for the freezing weather we are having right now!
This looks good. I will have to ask my wife if she could make this. Would go great with the cold weather.
This looks particularly good, given it’s currently 7 degrees F. Was afraid it’d be too spicy but looks OK. Thanks!
Yum, this sounds wonderful and so flavorful. Visiting from Inspirstion Monday 🙂
This looks really good! Perfect for the Winter months 🙂
This looks like it would be a hit at a game day party. I found your recipe over at the Two Cup Tuesday link party. I host Tickle My Tastebuds Tuesday and would love it if you would come over and share this recipe. I’m sure our party goers would love it! Here is the link http://bit.ly/1BXdrnz. Have a wonderful day!
