Slow Cooker Mexican Chicken Soup

Place chicken thighs in a large pot of water. Bring to a boil over high heat; reduce heat to medium-high and boil until no longer pink in the centers, about 30 minutes. Remove from the pot and let cool until able to handle, about 10 minutes. Shred chicken.

Place chicken broth, tomatoes, black beans, corn, tomato sauce, chiles, and taco seasoning into the bottom of a slow cooker. Add shredded chicken. Cover and cook on Low, 6 to 8 hours.

Serve topped with Cheddar cheese, sour cream, tortilla chips, and cilantro.
