This Chicken Taco Casserole is a comforting baked dish featuring shredded chicken, black beans, and diced tomatoes in a creamy taco-seasoned sauce, layered with crushed tortilla chips and cheese. It's finished with fresh toppings like tomato, green onion, and cilantro for added flavor.
For convenience, use shredded rotisserie chicken or leftover cooked chicken. Ensure tortilla chips are coarsely crushed, not pulverized, to maintain some texture. For a crispier base, you can lightly toast the chips before layering or reserve half the chips to add in the last 10-15 minutes of baking. Reserve some shredded cheese to sprinkle over the top halfway through baking for a fresher melted layer. Allow the casserole to rest for 5-10 minutes after baking before serving to help it set.
