How to Make Low Carb Chicken Fajita Soup

Heat the Pot: Start by heating a large pot or Dutch oven over medium-high heat. This prepares the base for all the rich flavors to come.
Sauté the Vegetables: Add butter, chopped onions, and diced bell peppers. Sauté for about 3-5 minutes until the onions are soft and translucent, creating a fragrant foundation for your soup.
Add Heat and Flavor: Stir in the finely chopped green chili and minced garlic, allowing them to sauté for an additional 30 seconds. This will awaken the spices and enhance the aroma.
Incorporate the Broth: Lower the heat and add 2 cups of chicken broth, stirring thoroughly. This will be the soup’s base, carrying all the delicious flavors.
Creamy Mix-In: Next, incorporate 6 oz of cream cheese, 2 cans of diced tomatoes, 1/2 cup of heavy cream, and 3 tbsp of taco seasoning. Whisk until smooth and creamy; this brings richness to the soup.
Add the Chicken: Gently fold in 2 lbs of cooked shredded chicken. Mix well until everything is combined, allowing the chicken to absorb all the fabulous flavors.
Simmer It Down: Let the soup simmer for about 5 minutes until the cheese melts beautifully. Taste and season with salt and black pepper to your liking.

Low Carb Chicken Fajita Soup Recipe FAQs

How do I select the best vegetables for my soup?

You can safely store your Low Carb Chicken Fajita Soup in an airtight container in the fridge for up to 3-4 days. Just make sure it cools down completely before sealing it to maintain freshness!
