- 2 lbs boneless skinless chicken breasts: The hearty protein base that will become tender and shreddable.

- 2 cups chicken broth: Creates a rich, savory soup base that ties everything together.
- 2 tablespoons taco seasoning: The magical blend that brings authentic fajita flavor to the dish.
- 2 teaspoons minced garlic: Infuses the soup with aromatic depth.
- ½ cup chopped onion: Adds a subtle sweetness and textural contrast.
- 1 green bell pepper, chopped: Provides a fresh, crisp bite and vibrant color.
- 1 red bell pepper, chopped: Brings sweetness and an inviting pop of red.
- Sour cream: For a cooling, creamy topping optional but highly recommended.
- Shredded cheddar cheese: Melts wonderfully on top, adding richness and sharpness.

How to Make Crock Pot Chicken Fajita Soup Recipe
Step 1: Combine Ingredients
Start by layering your crock pot with all the star ingredients. Place the chicken breasts at the bottom, followed by the diced tomatoes, chicken broth, taco seasoning, minced garlic, chopped onion, and the colorful bell peppers. Give everything a gentle stir so that the taco seasoning blends evenly and the veggies start mingling with the broth.
Step 2: Cook the Soup
Seal your crock pot with the lid and set it to cook low for about 6 to 8 hours. The slow cooking process allows the chicken to become incredibly tender while the flavors deepen and intensify. If you’re short on time, a high setting for 3 to 4 hours works too—just keep an eye to avoid overcooking.
Step 3: Shred the Chicken
Once cooked, carefully lift the chicken breasts out of the pot. Using two forks, shred the chicken into bite-sized pieces. This step is where things start coming together beautifully—the shredded chicken will soak up all that delicious soup liquid once returned to the crock pot.
Step 4: Stir and Finalize
Return the shredded chicken to the crock pot and stir everything thoroughly. This ensures that the chicken distributes evenly throughout the soup, allowing every spoonful to have that perfect mix of protein, veggies, and broth. Now your Crock Pot Chicken Fajita Soup Recipe is ready for serving!
How to Serve Crock Pot Chicken Fajita Soup Recipe

Garnishes
Nothing elevates this soup quite like vibrant toppings. A dollop of tangy sour cream adds creaminess that contrasts the spice, while shredded cheddar cheese melts enticingly over the hot soup, adding a rich, savory layer. Finish it off with a sprinkle of freshly chopped cilantro for a burst of fresh green color and herbal brightness.
Side Dishes
Pair this soup with warm, crusty bread or fluffy corn tortillas to soak up the flavorful broth.

Storing Leftovers

Reheating

FAQs
Can I use chicken thighs instead of breasts?

Can I make this recipe in an Instant Pot?
Yes, you can adapt the recipe for the Instant Pot by using the sauté function to combine ingredients, then cooking on high pressure for about 15 minutes followed by a natural release. Just shred the chicken and mix well before serving.
What if I don’t have bell peppers?
