Let’s dive into the step-by-step process of creating this delightful dish:

1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with a little bit of butter or cooking spray.
2. In a large mixing bowl, combine the shredded chicken, cream of chicken soup, sour cream, milk, garlic powder, onion powder, salt, and pepper. Stir until well mixed.
3. Spread the chicken mixture evenly into the prepared baking dish.
4. In a separate bowl, mix together the melted butter and crushed Ritz crackers until the crackers are well coated.
5. Sprinkle the cracker mixture evenly over the chicken mixture in the baking dish.
6. Top with shredded cheddar cheese, ensuring it’s evenly distributed.
7. Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
8. Remove from the oven and let it cool for a few minutes. If desired, garnish with chopped fresh parsley before serving.

As you prepare this casserole, remember the essence of cooking with love and patience, just like my abuela taught me when I was a child. Let your senses guide you — the sizzling of the cheese and the aroma filling your kitchen are signs that you’re on the right track.
