A delicious and convenient Chicken Cordon Bleu Freezer Casserole featuring tender chicken, ham, Swiss cheese, and a creamy sauce, perfect for preparing ahead and baking when ready.
3 cups cooked chicken, shredded or diced
1 1/2 cups cooked ham, diced
2 cups shredded Swiss cheese
2 cups cooked egg noodles
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
1/2 cup mayonnaise
1 teaspoon Dijon mustard
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon black pepper
1/4 teaspoon salt
1 cup crushed buttery crackers (such as Ritz)
2 tablespoons unsalted butter, melted
Preheat the oven to 350°F (175°C).
In a large mixing bowl, combine the cooked chicken, diced ham, shredded Swiss cheese, and cooked egg noodles. Mix gently to combine.
In a separate bowl, whisk together the condensed cream of mushroom soup, sour cream, mayonnaise, Dijon mustard, garlic powder, onion powder, black pepper, and salt until smooth.
Pour the sauce mixture over the chicken mixture and stir gently until everything is evenly coated.
Transfer the mixture into a greased 9×13-inch casserole dish and spread it evenly.
In a small bowl, combine the crushed buttery crackers with the melted butter and sprinkle the mixture evenly over the top of the casserole.
If freezing: Cover the casserole tightly with aluminum foil or plastic wrap and freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator.
Bake the casserole uncovered in the preheated oven for 40 to 45 minutes, or until the top is golden brown and the casserole is heated through.
Remove from the oven and let rest for 5 minutes before serving.
