Preparing the Casserole:
- Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray.
- Combine Casserole Ingredients: In a large bowl, mix together the cooked, shredded chicken, sour cream, mayonnaise, cream of chicken soup, milk, garlic powder, onion powder, paprika, salt, and pepper. Once combined, fold in the thawed mixed vegetables and half of the cheddar and Parmesan cheese until everything is well incorporated.
- Transfer to Baking Dish: Pour the chicken mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining cheddar cheese over the top.
Preparing the Topping:
- Mix Topping Ingredients: In a medium bowl, combine the crushed crackers, melted butter, garlic powder, paprika, and grated Parmesan cheese. Mix until the crackers are well coated in the butter and seasonings.
- Add Topping to Casserole: Evenly spread the cracker mixture over the top of the casserole, covering the chicken mixture and cheese layer.
Baking:
- Bake the Casserole: Place the casserole in the preheated oven and bake for about 25-30 minutes, or until the topping is golden brown and the casserole is bubbly around the edges.
- Cool and Serve: Allow the casserole to cool for a few minutes before serving. This resting period helps the casserole set and makes it easier to serve.
Serving Suggestions:
- Garnish: Add a sprinkle of fresh parsley or chives on top for a pop of color and freshness.
- Side Dishes: Serve this ultimate chicken casserole with a side of steamed green beans, a crisp salad, or some crusty bread to soak up the creamy sauce.
