Making Crock Pot Chicken Tortilla Soup is straightforward, and following these steps will ensure your success:

1. Prepare Ingredients: Begin by dicing the onion and mincing the garlic.
2. Add Chicken: Place the boneless, skinless chicken breasts in the bottom of the crock pot.
3. Layer Vegetables: Add the diced onion, minced garlic, black beans, corn, and undrained diced tomatoes on top of the chicken.
4. Spice It Up: Sprinkle chili powder, cumin, smoked paprika, salt, and pepper over the ingredients.
5. Pour Chicken Broth: Pour in the chicken broth, ensuring all ingredients are submerged as much as possible.
6. Set the Cooker: Cover and set your crock pot to low for 6-8 hours or high for 3-4 hours.
7. Check for Doneness: About 30 minutes before serving, check if the chicken is cooked through (internal temperature should be 165°F). If so, shred the chicken directly in the pot using two forks.
8. Stir and Combine: Stir all ingredients together well, mixing in the shredded chicken.
9. Taste and Adjust Seasoning: Taste your soup and adjust the seasoning if necessary.
10. Serve: Ladle the soup into bowls and garnish with tortilla strips, chopped cilantro, diced avocado, shredded cheese, and lime wedges.
