Unlike other creamy soups, this one packs in bold spices, lots of texture, and cheese that melts right into the broth. It’s like Chili’s Chicken Tortilla Soup, but with even more depth and that signature fajita twist.

How to Make Cheesy Slow Cooker Chicken Fajita Soup Step-by-Step

Step 1: Add Ingredients to Slow Cooker
Place the chicken breasts at the bottom of the slow cooker. Add onions, bell peppers, beans, tomatoes, green chilies, and all the spices. Pour in the chicken broth and stir gently to combine.

Step 2: Slow Cook
Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the chicken is fully cooked and tender.

Step 3: Shred the Chicken
Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken to the soup and stir.

Step 4: Add the Cheese
Add softened cream cheese and shredded cheddar to the soup. Stir until completely melted and smooth. Let it simmer uncovered for an additional 15–20 minutes to thicken slightly.

Step 5: Serve Hot
Ladle into bowls and add your favorite toppings. Serve with tortilla chips, warm bread, or even over rice.

This process is as easy as making Crack Breakfast Casserole or Pumpkin Chicken Chili—set it and let your slow cooker do the heavy lifting.

What Makes It Different from Chili’s Chicken Tortilla Soup?

While both soups share Tex-Mex roots, this chicken tortilla soup (Chili’s style) leans more brothy and tomato-heavy, whereas our version is ultra creamy and cheese-forward.

This creamy chicken fajita soup skips the tortilla strips in the base but keeps the fajita flavor alive with sautéed-style peppers, tender chicken, and bold spices. And let’s not forget the cheddar and cream cheese combo, which gives it that velvety texture missing from more traditional versions.

How to Store and Reheat Crockpot Fajita Soup Leftovers

This soup is fantastic for meal prep.

Refrigerator: Store in an airtight container for up to 4 days.

Freezer: Let the soup cool completely, then transfer to freezer-safe containers. Freeze for up to 3 months.

Reheat: Warm gently in a pot over medium heat, stirring occasionally. You can also microwave in a covered bowl, stirring halfway through.

Tip: Add a splash of broth or milk to thin the soup if it thickens too much after storing.

Common Mistakes to Avoid When Making Creamy Chicken Fajita Soup

• Not shredding chicken finely enough: Big chunks can overwhelm the texture.
• Using low-fat cream cheese: It may curdle or create a grainy texture.
• Adding cheese too soon: Wait until after shredding the chicken to prevent it from separating.
• Overcooking: Use a timer. Chicken breast becomes dry if cooked too long, even in a slow cooker.

Avoiding these common errors ensures a soup that’s silky, flavorful, and restaurant-worthy every time.

Pairing Ideas: What Goes Well with Chicken Fajita Soup?

• Tortilla chips and salsa
• Cornbread or cheesy biscuits
• Spanish rice
• Simple green salad with avocado dressing
• Sweet treats like Mini Pumpkin Bread with Cinnamon Swirl or Pumpkin Cheesecake Cookies

This soup makes a perfect match with just about any side, especially during colder months when cozy meals are everything.
