Place the chicken breasts in the bottom of a 4–6 quart slow cooker.
Add the drained black beans, drained kidney beans, corn, and diced tomatoes over the chicken.
Cut the cream cheese into cubes and scatter them on top of the other ingredients.
Sprinkle the chili seasoning evenly across the surface. Pour in 1 cup of chicken broth.
Stir gently so the cream cheese is distributed but don’t force it — it will melt as it cooks.
Cook on LOW for 6–8 hours or on HIGH for 4 hours.
About 30 minutes before serving, shred the chicken with two forks directly in the crock pot. Stir well to combine everything and let the cream cheese fully incorporate.
Taste and season with salt and pepper before serving.
Notes
For a spicier variation, add chopped chipotle peppers or cayenne pepper. Leftovers refrigerate for 3–4 days and freeze well for up to 3 months.
