Chicken Cordon Bleu Casserole Ingredients
• The perfect blend of flavors awaits!
- Unsalted Butter – Adds richness to the creamy Dijon sauce; using salted butter can result in excessive saltiness.
- Garlic – Provides aromatic flavor; if you’re in a pinch, garlic powder (1/4 tsp) works well too.
- Flour – Thickens the sauce for that perfect, creamy consistency; gluten-free flour can be used as a substitute for those avoiding gluten.
- Chicken Broth – Forms the base of the sauce, enhancing the chicken flavor; opt for low-sodium versions to keep it healthier.
- Milk – Creates a rich, creamy texture; feel free to choose skim, full cream, or even plant-based milk for a dairy-free alternative.
- Dijon Mustard – Infuses a tangy flavor into the sauce; yellow mustard makes a good alternative if you prefer milder tastes.
- Chicken or Vegetable Stock/Bouillon Powder – Intensifies the overall flavor profile; make sure to rehydrate as per package instructions.
- Parmesan Cheese – Enhances the depth of flavor; freshly grated cheese is best, but you can omit it if unavailable.
- Fresh Broccoli Florets – Provides vibrant color and nutrients; frozen broccoli works too, though you may need to adjust cooking time.
- Cooked/Roasted Chicken – The main protein; leftover rotisserie chicken is a great option that cuts down on prep time.
- Diced Ham – Adds a savory, smoky element; try turkey ham for a lighter twist!
- Swiss Cheese – Melts beautifully, contributing to the creamy texture; Gruyère or mozzarella can stand in if necessary.
- Panko Breadcrumbs – Creates that delightful crispy topping; if you prefer, regular breadcrumbs can be used as a substitute.
- Melted Butter – Binds the breadcrumbs for a perfect crust; provides added richness to the topping.
Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Make the Dijon Cream Sauce
Begin by melting 4 tablespoons of unsalted butter in a medium saucepan over medium heat. Sauté 2 cloves of minced garlic until fragrant, about 1 minute, then whisk in ¼ cup of flour to form a roux. Gradually pour in 2 cups of chicken broth and 1 cup of milk, whisking continuously for about 3-4 minutes until smooth and thickened. Stir in 2 tablespoons of Dijon mustard, 1 teaspoon of stock powder, and ¼ cup of grated Parmesan cheese, cooking until heated through. Season with salt and pepper to taste.
Step 2: Prepare Broccoli
In a large pot, bring water to a boil and add a pinch of salt. Blanch 2 cups of fresh broccoli florets in the boiling water for 2-3 minutes until they turn vibrant green and are crisp-tender. Drain the broccoli and immediately transfer it to an ice bath to stop the cooking process. Once cooled, drain again and set aside; this will add color and nutrients to your Chicken Cordon Bleu Casserole.
Step 3: Assemble Casserole
Preheat your oven to 400°F (200°C) while you layer your ingredients. In a greased casserole dish, start by placing 2 cups of shredded cooked chicken at the bottom, followed by the blanched broccoli and 1 cup of diced ham. Carefully pour the creamy Dijon sauce over the layers, ensuring an even distribution, and then sprinkle 2 cups of shredded Swiss cheese on top. The layers should be well-formed, creating a comforting base for your casserole.
Step 4: Add Breadcrumbs
To create that delightful crispy topping, combine 1 cup of Panko breadcrumbs with 2 tablespoons of melted butter in a small bowl. Mix until the breadcrumbs are thoroughly coated. Sprinkle this mixture evenly over the top of your layered casserole, ensuring coverage over the creamy cheese and ham for extra crunchiness. The breadcrumbs will provide a beautiful contrast to the creamy Chicken Cordon Bleu Casserole.
Step 5: Bake
Place the casserole in the preheated oven and bake uncovered for 30 minutes, or until the top is golden brown and bubbly. The edges should be slightly crispy, and you’ll notice the cheese melting enticingly underneath the breadcrumbs. Once baked, you can let it cool for a few minutes to set before serving, allowing the flavors to meld beautifully in this Chicken Cordon Bleu Casserole.
Make Ahead Options
Preparing the Chicken Cordon Bleu Casserole in advance is a fantastic way to simplify your meal planning! You can prep the creamy Dijon sauce and store it in the refrigerator up to 3 days before assembling. Additionally, the cooked chicken and diced ham can be combined with blanched broccoli and kept in an airtight container for up to 24 hours. When you’re ready to bake, simply pour the sauce over the assembled layers, top with cheese and breadcrumbs, and pop it in the oven. This method not only saves you valuable time during busy weeknights but also ensures that your casserole is just as delicious when it’s finally served. Enjoy the comforting flavors without the last-minute rush!
