Pour salsa into bottom of crockpot. Place chicken breasts on top. Sprinkle with taco seasoning. Add black beans and corn. Stir gently, ensuring sauce is underneath chicken.
Cover and cook on LOW for 8 hours or HIGH for 4 hours until chicken reaches 165°F internal temperature and shreds easily.
Use two forks to shred chicken directly in crockpot. Stir everything together to mix chicken with beans, corn, and sauce. Serve in taco shells, over bowls, in salads, or as dip.
Notes
Chicken thighs work great – cook 4-5 hours on LOW or 2-3 hours on HIGH. Boneless with skin removed.
Use crockpot liners for easy cleanup. Hand mixer makes shredding even easier.
Add jalapeños, cayenne, or hot salsa for extra spice. Store leftovers up to 4 days or freeze for 3 months.
