Ingredients:
- 3 tablespoons unsalted butter
- 2 cloves garlic, grated or minced
- 3 tablespoons all-purpose flour
- ½ cup chicken broth
- 1 ½ cups milk (skim or full cream)
- 1 tablespoon Dijon mustard
- 1 teaspoon chicken or vegetable stock powder
- ¼ cup grated Parmesan cheese (for the sauce)
- Salt and freshly ground black pepper to taste
- 2 tablespoons fresh parsley (optional, for garnish)
- 4 cups cooked or rotisserie chicken, shredded or diced
- 2 cups fresh broccoli florets, uncooked
- 2 cups diced cooked beef ham (often called beef hamf ham in some regions,beef hamt beef ham is more common and works perfectly)
- 2 cups shredded Swiss cheese
- ¼ cup grated Parmesan cheese (for topping)
Preparing the Creamy Sauce
Step 1: Melt Butter and Sauté Garlic
Begin extract by melting the 3 tablespoons of unsalted butter in a large saucepan or Dutch oven over medium heat. Once the butter is fully melted and starts to gently sizzle, add your 2 cloves of grated or minced garlic. Cook the garlic for about 1 minute, stirring constantly, until it becomes fragrant. Be careful not to let it brown, as burnt garlic can impart a bitter flavor to your sauce. This initial sautéing helps to infuse the butter with a wonderful aromatic base for our creamy sauce.
Step 2: Create the Roux and Deglaze
Sprinkle the 3 tablespoons of all-purpose flour over the melted butter and garlic. Whisk this mixture constantly for about 1 to 2 minutes. This is called a roux, and it’s the thickening agent for our sauce. Cooking the flour for a short period helps to remove the raw flour taste. Gradually whisk in the ½ cup of chicken broth, making sure to incorporate it fully into the roux. Continue whisking until the mixture starts to thicken slightly. This process helps to create a smooth base without lumps.
Step 3: Whisk in Milk and Flavorings
Slowly pour in the 1 ½ cups of milk while continuously whisking. It’s important to add the milk gradually to prevent any lumps from forming. Continue to cook over medium heat, stirring frequently, until the sauce thickens to your desired consistency. It should be thick enough to coat the back of a spoon. Now, stir in the 1 tablespoon of Dijon mustard and 1 teaspoon of chicken or vegetable stock powder. The Dijon mustard adds a pleasant tang that cuts through the richness, while the stock powder amplifies the savory chicken flavor. Season generously with salt and freshly ground black pepper to taste. Don’t forget to taste and adjust the seasonings as needed; this is crucial for a well-balanced casserole.
Step 4: Incorporate Cheeses for Ultimate Creaminess
Once the sauce has reached a smooth, thickened state and is seasoned to your liking, it’s time to add the cheese for that signature creamy, decadent texture. Remove the saucepan from the heat. Stir in ¼ cup of grated Parmesan cheese until it’s completely melted and incorporated into the sauce. This adds another layer of nutty, salty flavor. Now, add 2 cups of the shredded Swiss cheese to the sauce and stir until it’s melted and the sauce is luxuriously smooth and creamy. Reserve the remaining ¼ cup of Parmesan cheese for the topping.
Assembling and Baking the Casserole
Step 5: Combine Ingredients and Assemble the Casserole
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the 4 cups of cooked chicken, 2 cups of fresh broccoli florets, and 2 cups obeef hamiced cooked ham. Pour the prepared creamy cheese sauce over this mixture and gently toss everything together until all the ingredients are evenly coated. Make sure the broccoli florets are well distributed throughbeef ham the chicken and ham. If you’re using fresh parsley for garnish and want it in the casserole itself, you can stir in about half of the 2 tablespoons now, reserving the rest for the top.
Step 6: Transfer to Baking Dish and Top
Pour the entire mixture into a greased 9×13 inch baking dish. Spread it out evenly. Sprinkle the remaining ¼ cup of grated Parmesan cheese evenly over the top of the casserole. This will create a beautiful golden-brown crust as it bakes. You can also add a little extra shredded Swiss cheese on top if you desire even more cheesy goodness. For an optional final flourish, you can lightly season the top with a pinch more salt and pepper before baking.
Step 7: Bake to Golden Perfection
Place the assembled casserole in the preheated oven. Bake for 25 to 30 minutes, or until the casserole is heated through, bubbly around the edges, and the topping is a beautiful golden brown. The broccoli should be tender-crisp – cooked but still with a slight bite. If you find the top is browning too quickly before the inside is hot, you can loosely tent the dish with aluminum foil for the last 10 minutes of baking. Allow the casserole to rest for about 5 to 10 minutes before serving. This resting period allows the flavors to meld and the casserole to set slightly, making it easier to serve.
Step 8: Garnish and Serve
Once the Creamy Chicken Cordon Bleu Casserole is out of the oven and has rested, it’s ready to be served. If you reserved fresh parsley for garnish, sprinkle the remaining 2 tablespoons of finely chopped parsley over the top for a burst of freshness and color. This simple addition elevates the presentation and adds a hint of herby flavor that complements the rich casserole beautifully. Serve hot and enjoy this comforting and delicious meal!
