“Made this last Christmas for a Christmas party…. had to turn around a few hours later to make another batch”

In a large bowl, mix together the cream of chicken soup, cream of mushroom soup, sour cream, mayonnaise, chicken broth, garlic powder, onion powder, salt, and pepper. Stir until well combined.
Add the cooked chicken to the mixture and fold it in gently.
Assemble the casserole:

Pour the chicken mixture into the prepared baking dish and spread it evenly.
Top with cheese:

Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
Make the topping:

In a small bowl, mix the crushed crackers with the melted butter. Spread this mixture over the top of the casserole, followed by a sprinkle of Parmesan cheese (if using).
Bake:

Bake in the preheated oven for 30-40 minutes or until the top is golden and bubbly.
Serve:

Allow the casserole to cool for a few minutes before serving. It pairs well with a side of vegetables or a fresh salad.
Optional Variations:
Add vegetables like peas, corn, or carrots to the casserole for more texture and flavor.
Swap out the mayo and sour cream for Greek yogurt for a lighter version.
Add some fresh herbs like parsley or thyme to brighten up the flavor.
This dish is great for gatherings because it can easily be prepared ahead of time and is loved by almost everyone. Enjoy!
