Prep the Chicken: Place the boneless chicken breasts at the bottom of the crockpot. Season them with salt, pepper, chili powder, cumin, and smoked paprika on both sides.
Add Vegetables: Add the diced green and yellow bell peppers, chopped onion, and minced garlic on top of the chicken.
Incorporate the Liquid: Pour in the diced tomatoes with their juice and the chicken broth. If using, stir in the corn.
Cook: Cover the crockpot and set it on low for 6-8 hours or on high for 3-4 hours, allowing the flavors to blend and the chicken to become tender.
Shred the Chicken: About 30 minutes before serving, remove the chicken breasts and shred them using two forks. Return the shredded chicken to the chili and stir well.
Taste and Adjust: Taste the chili and adjust seasoning if necessary, adding more salt or spices to your liking.
Serve: Ladle the chili into bowls and garnish with fresh cilantro.
Notes
Serve in bowls topped with additional cilantro and perhaps a dollop of Greek yogurt or avocado slices for creaminess.
