Stir in crushed tomatoes, Rotel diced tomatoes with juices, and chicken broth. Add garlic powder, smoked paprika, chili powder, corn, and black beans. Mix thoroughly and increase heat to high.
When the soup comes to a boil, reduce heat to low and cover the pot with the lid slightly ajar. Let it simmer gently for 5 minutes.
Prepare toppings while the soup simmers: slice avocados, shred cheese, and prepare tortilla strips.
Stir in the heavy cream and cooked chicken pieces. Continue warming the soup for 3 to 5 minutes until heated through. Taste and adjust seasoning.
Ladle soup into bowls and garnish with tortilla strips, avocado, sour cream, and Tex Mex cheese. Serve immediately.
Notes
For variations, you can use shredded turkey instead of chicken or coconut milk instead of heavy cream for a dairy-free option.
