Cook the chicken: Add the chicken pieces to the pot and season with taco seasoning, salt, and pepper. Cook for about 5-7 minutes, stirring occasionally, until the chicken is no longer pink.
Add the canned ingredients: Pour in the diced tomatoes, black beans, corn, and chicken broth. Stir well to combine and bring the mixture to a boil.
Simmer and incorporate cream cheese: Lower the heat and let the soup simmer for 15-20 minutes. After simmering, add the softened cream cheese, stirring until fully melted and incorporated into the soup.
Adjust seasoning: Taste and adjust seasoning as needed. If desired, add more taco seasoning or additional salt and pepper.
Serve hot: Ladle the soup into bowls and top with your choice of garnishes like cilantro, sour cream, shredded cheese, or avocado slices.
Notes
For a thicker soup, allow to simmer longer or mash some beans; adjust spice levels to taste.
