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, your preference)
- 1 tablespoon Dijon mustard
- 1 teaspoon chicken or vegetable stock/bouillon powder
- ¼ cup fresh grated Parmesan cheese (for the sauce)
- Salt and freshly ground black pepper to taste
- 2 tablespoons fresh parsley, finely chopped (optional, for garnish)
- 4 cups cooked or rotisserie chicken, shredded or diced
- 2 cups fresh broccoli florets, uncooked
- 2 cups beef beef ham, diced
- 2 cups Swiss cheese, shredded
- ¼ cup fresh grated Parmesan cheese (for topping)
Preparing the Creamy Sauce
The foundation of our Creamy Chicken Cordon Bleu Casserole is a rich and velvety sauce. This is where all the flavor truly comes together. Let’s start by melting the butter in a large saucepan or Dutch oven over medium heat. Once the butter has melted and is shimmering slightly, add the minced garlic. Sauté the garlic for about 30 seconds until it becomes fragrant. Be careful not to let it brown, as burnt garlic can impart a bitter taste.
Next, we’ll create a roux, which will thicken our sauce. Sprinkle the flour over the melted butter and garlic. Whisk continuously for about 1 to 2 minutes. This step is crucial for cooking out the raw flour taste and ensuring a smooth sauce. You’ll see the mixture become a thick paste. This is exactly what we want.
Now, it’s time to introduce the liquids. Gradually whisk in the chicken broth. Keep whisking to prevent any lumps from forming. Once the broth is incorporated, slowly pour in the milk while continuing to whisk. It might seem like a lot of liquid at first, but it will come together beautifully. Continue to cook and stir the sauce over medium heat. As it heats up, it will begin extract to thicken. You are looking for a consistency that coats the back of a spoon. This usually takes about 5 to 7 minutes.
Once the sauce has thickened to your liking, stir in the Dijon mustard and the chicken or vegetable stock/bouillon powder. The Dijon mustard adds a delightful tang that complements the richness of the cheese, while the bouillon powder intensifies the savory chicken flavor. Stir until the bouillon powder is completely dissolved. Finally, stir in ¼ cup of the fresh grated Parmesan cheese. Continue stirring until the cheese is melted and fully incorporated into the sauce. This will add another layer of cheesy goodness and a lovely depth of flavor. Season the sauce generously with salt and freshly ground black pepper to your personal taste. Remember to taste and adjust as needed.
Assembling the Casserole
With our luscious sauce ready, it’s time to bring all the delicious components together for our Creamy Chicken Cordon Bleu Casserole. In a large mixing bowl, combine the shredded or diced cooked chicken, the diced beef hamf ham, and the uncooked broccoli florets. Make sure the broccoli florets are bite-sized; if they are too large, they might not cook through as effectively in the casserole.
Pour about two-thirds of the creamy cheese sauce over thebeef hamicken, ham, and broccoli mixture. Gently toss everything together until all the ingredients are evenly coated with the sauce. Ensure every piebeef hamof chicken, ham, and every floret of broccoli is nestled in that delicious, creamy goodness. This initial coating helps to distribute the flavor and moisture evenly throughout the casserole.
Now, it’s time to add the Swiss cheese. Add 2 cups of the shredded Swiss cheese to the bowl and gently fold it into the mixture. Don’t overmix at this stage; we want some pockets of melted Swiss cheese throughout the casserole, rather than having it completely disappear into the sauce.
Baking the Casserole
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This will prevent the casserole from sticking and make cleanup a breezebeef hamour the chicken, ham, broccoli, and cheese mixture evenly into the prepared baking dish. Spread it out so you have a nice, even layer.
Pour the remaining one-third of the creamy cheese sauce over the top of the casserole. This final layer of sauce will create a wonderfully moist and flavorful topping as it bakes. Then, sprinkle the remaining ¼ cup of fresh grated Parmesan cheese evenly over the entire surface of the casserole. This will create a beautiful golden-brown, slightly crispy topping.
Cover the baking dish tightly with aluminum foil. This is important to ensure the broccoli cooks through and the casserole heats evenly without the top getting too brown too quickly. Bake for 20 minutes. After 20 minutes, remove the foil and continue baking for another 15-20 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and slightly crisp. The cheese should be melted and gooey, and the broccoli should be tender-crisp.
Resting and Serving
Once the Creamy Chicken Cordon Bleu Casserole is out of the oven, resist the urge to dig in immediately! Let it rest for about 10 minutes before serving. This resting period allows the flavors to meld together and the casserole to set slightly, making it easier to serve without it falling apart. This is a crucial step for achieving the perfect texture.
Just before serving, garnish with the finely chopped fresh parsley, if desired. The bright green parsley adds a lovely pop of color and a hint of freshness that cuts through the richness of the dish. Serve hot and enjoy this incredibly comforting and delicious Creamy Chicken Cordon Bleu Casserole. It’s a complete meal on its own but also pairs wonderfully with a simple side salad or some crusty bread.
