Step 1: Prepare the Chicken

  1. Preheat your oven to 375°F (190°C).

  4. Repeat the layers with the remaining chicken mixture and shredded cheese.

Step 3: Bake to Perfection

  1. Bake the casserole in the preheated oven for 25-30 minutes or until the cheese is melted and bubbly, and the edges are golden brown.
  2. Remove from the oven and let it cool for a few minutes.

Step 4: Garnish and Serve

  1. Garnish the Fiesta Chicken Casserole with chopped fresh cilantro and serve with avocado slices and lime wedges on the side.
  2. Slice into portions and serve warm.
