How to Make Low-Carb Chicken Fajita Soup

This soup is effortless to make in the slow cooker with only a few simple ingredients. Place boneless chicken breasts in the crockpot. Sprinkle fajita seasoning over the chicken. Add chopped onion, bell pepper, Rotel diced tomatoes and green chiles, chili powder, cilantro, and chicken broth. Place a block of cream cheese on top of the ingredients. Cover the slow cooker and cook on LOW for 6 to 8 hours. Remove the chicken breasts from the slow cooker and shred them with two forks. Whisk the soup to get the cream cheese fully incorporated. Stir in the shredded chicken and serve.

Helpful Tips & Frequently Asked Questions

  • You can use any boneless skinless chicken that you prefer. Chicken breasts, chicken thighs, or chicken tenderloins.
  • I use Badia Fajita Seasoning. It has zero carbs. I find it in the International Foods section at the grocery store.
    • Can substitute taco seasoning if you can’t find fajita seasoning.
    • Here is our recipe for homemade taco seasoning made with chili powder, garlic powder, onion powder, red pepper flakes, oregano, paprika, cumin, salt, and black pepper: https://www.plainchicken.com/homemade-taco-seasoning/
  • I suggest using low-sodium or no-salt chicken broth.
  • Can I make Chicken Fajita Soup on the stovetop? Yes! Add the ingredients to a Dutch oven or large pot. Bring to a boil over medium-high heat. Reduce heat and simmer until the chicken is cooked. Remove the chicken from the pot and shred with two forks. Stir in the chicken and serve.
    • Can substitute cooked chopped chicken such as rotisserie chicken for raw chicken breasts for a quick stovetop meal.
  • If not doing a low-carb or keto diet, feel free to add in corn and black beans or pinto beans. 
    • Cooked rice is also a great addition to the soup.
  • Can Chicken Fajita Soup be frozen? Yes! Cook the soup and cool it completely. Transfer soup to freezer bags or freezer-safe food containers. Store in the freezer for up to three months.
    • Reheat the soup on the stovetop or in the microwave.
  • Store leftovers in an airtight container in the refrigerator.

What to Serve with Chicken Soup

We like to top our bowls of soup with shredded cheese, sour cream, and a squirt of fresh lime juice. It is equally delicious with some tortilla chips and sliced avocado or guacamole. Whip up a Mexican Chopped Salad or some cornbread if you aren’t doing keto. One bite and this is sure to become a family favorite!
