Place chicken breasts in a single layer at the bottom of a 4-6 quart slow cooker. If breasts are very thick, cut in half horizontally.
Sprinkle ranch seasoning mix, chili powder, cumin, and garlic powder evenly over the chicken.
Add corn, black beans, and Rotel tomatoes over the seasoned chicken, spreading evenly without stirring.
Pour chicken broth over ingredients until liquid comes about halfway up the contents. Place cubed cream cheese pieces evenly on top.
Cover and cook on low for 6-8 hours or on high for 4-6 hours until chicken shreds easily with a fork.
After 5.5-7.5 hours of cooking (30 minutes before serving), shred chicken with two forks directly in the slow cooker and stir to combine all ingredients.
Stir in shredded cheddar cheese and crumbled bacon. Cover and let sit for 10-15 minutes until cheese melts completely.
Give a final stir and serve warm with desired toppings like extra cheese, sour cream, and green onions.
Notes
Use a 4-6 quart slow cooker for this recipe. Cube cream cheese before adding for smooth, even melting.
Cook bacon ahead of time for easier prep. If cooking fresh bacon, add 15 minutes to prep time. Chicken thighs can be substituted for richer flavor.
Add diced jalapeños or cayenne pepper for extra heat. Use spicy Rotel for bolder flavor.
Chili thickens upon standing. Add a splash of broth when reheating if needed.
Freezes well for up to 3 months. Thaw overnight in refrigerator before reheating.
Use full-fat cream cheese for best texture. Reduced-fat will work but result in slightly thinner consistency.
