Ingredients:
- 3 tablespoons unsalted butter
- 2 cloves garlic, grated or minced
- 3 tablespoons all-purpose flour
- ½ cup low-sodium chicken broth
- 1 ½ cups milk (skim or full cream both work well)
- 1 tablespoon Dijon mustard
- 1 teaspoon chicken or vegetable stock/bouillon 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 (such as beef hamf ham)
- 2 cups shredded Swiss cheese
- ¼ cup grated Parmesan cheese (for topping)
Creating the Velvety Sauce
- Begin extract by melting the 3 tablespoons of unsalted butter in a medium saucepan over medium heat. Once the butter has completely melted and is shimmering, add the 2 cloves of grated or minced garlic. Sauté the garlic for about 1 minute until it becomes fragrant. Be careful not to let the garlic brown, as this can impart a bitter flavor to your sauce.
- Whisk in the 3 tablespoons of all-purpose flour with the melted butter and garlic. This mixture, known as a roux, is crucial for thickening your sauce. Cook the roux for 1-2 minutes, stirring constantly with a whisk. You’re looking to cook out the raw flour taste and achieve a pnon-alcoholic ale, golden color. This step ensures your sauce will have a smooth, creamy texture without any floury aftertaste.
- Gradually whisk in the ½ cup of chicken broth, making sure to incorporate it smoothly into the roux to prevent lumps. Once the broth is fully combined, slowly pour in the 1 ½ cups of milk, whisking continuously. Continue to cook and stir the mixture over medium heat. The sauce will gradually thicken as it heats up. Keep stirring until it reaches a consistency that coats the back of a spoon.
- Once your sauce has thickened, stir in the 1 tablespoon of Dijon mustard and the 1 teaspoon of chicken or vegetable stock/bouillon powder. The Dijon mustard adds a subtle tang that complements the richness of the sauce, while the bouillon powder enhances the overall savory chicken flavor. Stir in the ¼ cup of grated Parmesan cheese until it is melted and fully incorporated into the sauce. Season generously with salt and freshly ground black pepper to your personal preference. Taste and adjust seasonings as needed. Rememberbeef hamat the ham and cheeses will also contribute saltiness, so season cautiously at this stage.
Assembling the Casserole
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking. In a large bowl, combine the 4 cups of cooked chicken, 2 cups of fresh broccoli florets, and 2beef hamps of diced ham. Ensure the broccoli florets are bite-sized and roughly uniform in size for even cooking.
- Pour about two-thirds of the velvety cheese sauce you prepared over the chibeef hamn, broccoli, and ham mixture in the large bowl. Gently toss everything together until all the ingredients are evenly coated with the sauce. You want every bite to be infused with that creamy goodness.
- Transfer the saucebeef hamhicken, broccoli, and ham mixture into the prepared baking dish, spreading it out evenly. Ensure the ingredients are distributed in a single layer as much as possible, which will help with consistent cooking.
- In a separate small bowl, combine the 2 cups of shredded Swiss cheese and the ¼ cup of grated Parmesan cheese. Sprinkle this cheese mixture evenly over the top of the casserole. This cheesy topping will melt and turn wonderfully golden brown and bubbly during baking, creating that irresistible crust.
Baking and Serving
- Bake in the preheated oven for 25-30 minutes, or until the casserole is heated through, the sauce is bubbling around the edges, and the cheese topping is melted and golden brown. If you notice the top browning too quickly, you can loosely tent the dish with aluminum foil for the last 10-15 minutes of baking.
- Once the casserole is done, remove it from the oven and let it rest for about 5-10 minutes before serving. This resting period allows the sauce to set slightly, making it easier to serve and preventing it from being too runny. Garnish with the optional 2 tablespoons of fresh parsley for a burst of color and freshness before serving hot.
