First Step: Preheat the Oven and Prepare the Baking Dish : Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with cooking spray or a small amount of butter. This will prevent the casserole from sticking and help achieve that perfect golden crust.
Second Step: Prepare the Casserole Base : In a large mixing bowl, combine the shredded chicken, cream of chicken soup, cream of mushroom soup, sour cream, shredded cheddar cheese, frozen peas, chopped onion, and celery. Stir everything together until evenly mixed. Season with salt, pepper, and garlic powder to taste.
Third Step: Transfer the Mixture to the Baking Dish : Pour the casserole mixture into the prepared baking dish, spreading it out evenly to ensure uniform cooking.
Fourth Step: Prepare the Topping : In a small bowl, mix the breadcrumbs with melted butter. Stir until the breadcrumbs are evenly coated. Sprinkle this breadcrumb mixture over the top of the casserole to create a crispy, golden crust.
Fifth Step: Bake the Casserole : Place the baking dish in the preheated oven and bake for 25-30 minutes. You’ll know the casserole is done when it’s bubbling around the edges, and the breadcrumbs are golden brown.
Sixth Step: Serve and Enjoy : Allow the casserole to rest for a few minutes before serving. This will help it set and make it easier to serve. Scoop portions into bowls, and enjoy the creamy, savory goodness of Company Casserole!
