Cheesy Chicken Cordon Bleu Casserole

There are certain smells that instantly transport me back to my childhood, and one of them is the comforting aroma of baked ham and cheese. My grandmother, a woman who believed in the power of simple, home-cooked meals, used to make a similar dish every holiday season. It wasn’t exactly Cordon Bleu, but it was a cheesy, ham-filled delight that always brought smiles to our faces. This Cheesy Chicken Cordon Bleu Casserole is my modern take on that classic comfort food, elevated with tender chicken and a creamy, flavorful sauce. It’s a dish that’s as perfect for a weeknight family dinner as it is for a potluck gathering.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 5 minutes
• Servings: 4-6
• Yield: 1 casserole
• Dietary Type: Not Gluten-Free

Ingredients

• 4 cups chicken, cooked and cubed
• 3 cups ham, cooked and cubed
• 2 cups mozzarella cheese, shredded
• 1/4 cup butter
• 1/3 cup flour
• 2 cups milk
• 1 teaspoon ground mustard
• 1 teaspoon nutmeg

Equipment Needed

• 9 x 13 inch baking pan
• Large bowl
• Large saucepan
• Whisk
• Non-stick cooking spray

Instructions

1. Preheat your oven to 375°F (190°C).
2. Lightly spray a 9 x 13 inch baking pan with non-stick cooking spray. This will ensure that your casserole doesn’t stick and makes for easy cleanup.
3. In a large bowl, combine the 4 cups of cooked and cubed chicken, 3 cups of cooked and cubed ham, and 2 cups of shredded mozzarella cheese. Mix gently to combine and set aside. Ensure your chicken and ham are cut into similar sized pieces for even distribution in the casserole.
4. In a large saucepan, melt 1/4 cup of butter over medium heat.
5. Add 1/3 cup of flour to the melted butter. Whisk constantly to create a smooth paste, also known as a roux. Cook the roux for about 2 minutes, stirring continuously, to cook out the raw flour taste. Be careful not to burn the butter; a light golden color is what you’re aiming for.
6. Gradually add 2 cups of milk to the roux, whisking constantly to prevent lumps from forming. Heat the mixture to a boil, stirring continuously until the sauce thickens. It should coat the back of a spoon.
7. Remove the saucepan from the heat. Stir in 1 teaspoon of ground mustard and 1 teaspoon of nutmeg. These spices add a subtle depth of flavor to the creamy sauce. Taste and adjust seasonings as needed. Some may prefer a little salt and pepper.
8. Pour the sauce over the chicken and ham mixture in the large bowl. Gently toss to coat all the ingredients evenly. Make sure everything is well coated to prevent any dry spots in the casserole.
9. Transfer the chicken and ham mixture into the prepared 9 x 13 inch baking pan, spreading it out evenly.
10. Bake the casserole uncovered in the preheated oven for 45 minutes, or until the top is bubbly and golden brown. The cheese should be melted and slightly browned.
11. Remove from the oven and let it rest for a few minutes before serving. This allows the casserole to set slightly, making it easier to serve.

Expert Tips & Tricks

• Make-Ahead Tip: Prepare the chicken and ham mixture, combine it with the cheese, and store it in the freezer for up to a month. Defrost in the refrigerator overnight before cooking. This significantly cuts down on prep time, making it perfect for busy weeknights. The sauce can also be made a day in advance and stored in the refrigerator.
• Cheese Variations: While mozzarella is classic, you can experiment with other cheeses like Gruyere, Swiss, or provolone for a richer, more complex flavor. A combination of cheeses can also be delicious.
• Preventing a Dry Casserole: If you find that your casserole is getting too brown on top before it’s fully heated through, you can tent it with aluminum foil for the last 15-20 minutes of baking.
• Adding Vegetables: Feel free to add some cooked vegetables to the chicken and ham mixture for added nutrients and flavor. Broccoli florets, peas, or asparagus would be excellent additions.
• Spice It Up: For a little kick, add a pinch of cayenne pepper or a dash of hot sauce to the sauce.

Serving & Storage Suggestions

This Cheesy Chicken Cordon Bleu Casserole is best served warm, straight from the oven. Garnish with a sprinkle of fresh parsley or chives for a pop of color. It pairs perfectly with a simple green salad, steamed green beans, or roasted asparagus.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions or bake the entire casserole covered with foil in a preheated oven at 350°F (175°C) until heated through.

For longer storage, the casserole can be frozen for up to 2-3 months. Thaw it in the refrigerator overnight before reheating. Note that the texture of the sauce may change slightly after freezing and thawing.

FAQs (Frequently Asked Questions)

Q: Can I use rotisserie chicken for this recipe?
