The Key Ingredients You’ll Need
This recipe uses simple, easy-to-find ingredients to create a truly spectacular dish. Here’s what you’ll need to gather.
For the Casserole Base
- Chicken: Boneless, skinless chicken breasts, cooked and cubed. Rotisserie chicken works wonderfully here to save time.
- Ham: Good quality deli ham, like Black Forest or Virginia ham, chopped into bite-sized pieces.
- Swiss Cheese: Freshly grated Swiss cheese melts beautifully and provides that classic, nutty flavor.
For the Creamy Dijon Sauce
- Butter: The base for our rich and flavorful roux.
- All-Purpose Flour: To thicken the sauce.
- Milk: Use whole milk for the creamiest results.
- Dijon Mustard: This adds the signature tangy flavor that cuts through the richness of the cheese and cream.
- Garlic Powder & Onion Powder: For a savory depth of flavor.
- Salt & Black Pepper: To taste.
For the Crispy Panko Topping
- Panko Breadcrumbs: These Japanese-style breadcrumbs provide a superior crunch compared to regular breadcrumbs.
- Melted Butter: To toast the breadcrumbs to a perfect golden brown.
- Parmesan Cheese: Adds a salty, cheesy bite to the topping.
- Parsley: Freshly chopped parsley adds a touch of color and freshness.
How to Make Chicken Cordon Bleu Casserole Step-by-Step
Ready to create this masterpiece? Follow these simple steps for a perfect Chicken Cordon Bleu Casserole every time.
- Preheat and Prepare: First, preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Layer the Base: Spread the cooked, cubed chicken evenly across the bottom of the prepared dish. Top the chicken with an even layer of chopped ham. Sprinkle half of the grated Swiss cheese over the ham.
- Make the Creamy Sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for one minute to create a roux. Gradually pour in the milk, whisking constantly to prevent lumps. Continue to cook, whisking frequently, until the sauce thickens, about 5-7 minutes. Remove from heat and stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper.
- Assemble the Casserole: Pour the creamy Dijon sauce evenly over the layers in the baking dish. Sprinkle the remaining Swiss cheese on top of the sauce.
- Prepare the Topping: In a small bowl, combine the Panko breadcrumbs, melted butter, grated Parmesan cheese, and fresh parsley. Mix until the breadcrumbs are evenly moistened.
- Bake to Perfection: Sprinkle the breadcrumb mixture evenly over the casserole. Bake for 25-30 minutes, or until the sauce is bubbly and the topping is golden brown and crispy. Let it rest for a few minutes before serving.
Expert Tips for the Best Casserole
Want to ensure your Chicken Cordon Bleu Casserole is absolutely flawless? Here are a few pro tips:
- Grate Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can prevent it from melting smoothly. For the best, gooiest results, buy a block of Swiss cheese and grate it yourself.
- Don’t Overbake: Since the chicken is already cooked, you’re primarily heating the dish through and melting the cheese. Overbaking can dry out the chicken. Bake just until it’s hot, bubbly, and the topping is golden.
- Let it Rest: Allow the casserole to rest for 5-10 minutes after removing it from the oven. This helps the sauce set up slightly, making it easier to serve.
Delicious Serving Suggestions
This casserole is a hearty meal on its own, but it pairs beautifully with a variety of side dishes. Consider serving it with a simple green salad with a vinaigrette, steamed green beans, roasted asparagus, or a side of fluffy rice. For another comforting meal, try this easy and hearty goulash recipe.
Storage, Freezing, and Reheating Instructions
One of the best things about this dish is how well it stores. Leftovers can be kept in an airtight container in the refrigerator for up to 4 days. You can also freeze the casserole either before or after baking. To freeze before baking, assemble as directed but leave off the breadcrumb topping. Cover tightly and freeze for up to 3 months. When ready to bake, thaw in the refrigerator overnight, add the fresh topping, and bake as directed, adding 10-15 minutes to the cooking time.
Fun Variations to Try
Feel free to customize this Chicken Cordon Bleu Casserole to your liking! You could mix in some cooked pasta to make it even heartier. For a different flavor profile, try using provolone or gruyere cheese instead of Swiss. If you enjoy a touch of green, adding cooked broccoli florets or peas is a great way to sneak in some extra veggies. For a similar cheesy chicken dish with a twist, check out our spinach artichoke chicken bake.
