Set your oven to 350°F to ensure it reaches the ideal temperature while you prepare the dish. This step guarantees that your casserole will bake evenly, resulting in a perfectly crisp topping and a bubbling, creamy center.

In a large bowl, mix the cream cheese, sour cream, and cream of chicken soup until well combined.. Blend them until smooth and velvety. To elevate the flavor, stir in garlic powder and onion powder, ensuring the seasoning is evenly distributed.

Carefully fold in the shredded chicken and cottage cheese, ensuring the mixture is evenly incorporated without breaking apart the textures. This step ensures every piece of chicken is coated in a rich, creamy sauce, creating a uniform filling that’s bursting with flavor.

Prepare a greased 9x9-inch casserole dish. Evenly spread the creamy chicken mixture into the dish, smoothing it out with a spatula. This creates a solid base for your crispy topping to shine.

In a small bowl, mix crushed Ritz crackers with melted butter until the crumbs are thoroughly coated. This mixture delivers the casserole’s signature buttery crunch. Evenly distribute the cracker topping over the chicken mixture, making sure to cover every corner for a consistent, crunchy layer.

Place the casserole on the middle rack of your preheated oven. Bake uncovered for 25–30 minutes, or until the edges bubble and the topping turns a beautiful golden brown. Take the casserole out of the oven and allow it to rest for 5 minutes before serving. Garnish with fresh parsley if desired, then serve and enjoy the comforting flavors of this irresistible dish.
