Place chicken breasts in the bottom of the crockpot. If using frozen chicken, add an extra hour to the cook time.
Pour salsa, black beans, and corn over the chicken. Sprinkle cumin, chili powder, garlic powder, salt, and pepper on top. Do not stir.
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until chicken shreds easily with a fork.
Shred chicken with two forks directly in the pot. Stir to combine with sauce and vegetables.
Optional: Add cream cheese or shredded cheddar, cover for 5 minutes to melt, then stir until creamy.
Serve in bowls, wraps, or over rice. Garnish with cilantro and a squeeze of lime if desired.
Notes
Swap black beans with pinto or white beans if needed. For a dairy-free creamy version, stir in mashed avocado before serving. Freezes well for up to 3 months.
