How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Prepare the Oven and Casserole Dish
Start by preheating your oven to 350 degrees Fahrenheit, and lightly spray a 9×13 casserole dish with cooking spray. This step ensures even baking and prevents sticking, making cleanup a breeze.
Step 2: Layer the Chicken and Ham
Begin assembling your casserole by layering the shredded rotisserie chicken evenly on the bottom of your prepared dish. Next, scatter the cubed ham evenly over the chicken. This layering locks in moisture and builds the hearty foundation for your casserole.
Step 3: Make the Cheese Sauce
In a medium saucepan over medium heat, melt the butter. Sprinkle the flour over the melted butter, stirring constantly for 1 to 2 minutes until the mixture is dry and clumpy. Slowly whisk in the milk, making sure to combine smoothly. Add the Dijon mustard, lemon juice, garlic powder, and salt, then simmer gently for 3 to 5 minutes, whisking all the while until thickened to a luscious sauce. Remove from heat and stir in the shredded Swiss and grated Parmesan cheese until melted and fully incorporated. Taste and adjust salt seasoning if needed. Pour this rich, creamy sauce evenly over the layered chicken and ham in the casserole dish.
Step 4: Add the Crunchy Panko Topping
Combine the panko bread crumbs with the melted butter in a small bowl. Mix well to coat evenly, then sprinkle this topping generously over your cheese-covered casserole. This crunchy layer will bake to a golden crisp, adding delightful texture.
Step 5: Bake Until Golden and Bubbling
Place your casserole in the preheated oven and bake uncovered for 30 to 35 minutes. You’ll know it’s ready when the breadcrumbs turn a satisfying golden brown and the filling bubbles warmly underneath. Let it rest for 5 to 10 minutes before serving to allow the flavors to settle.
How to Serve Chicken Cordon Bleu Casserole Recipe
Garnishes
Sprinkle fresh chopped parsley or chives over the casserole just before serving to add a pop of color and subtle freshness that cuts through the richness. A light drizzle of extra lemon juice can also brighten each bite wonderfully.
Side Dishes
This casserole pairs beautifully with crisp green beans, a fresh garden salad, or roasted vegetables like asparagus or Brussels sprouts. Creamy mashed potatoes or buttery egg noodles also make comforting companions, soaking up any delicious sauce left on the plate.
Creative Ways to Present
For a crowd-pleasing presentation, serve the Chicken Cordon Bleu Casserole Recipe in individual ramekins or small baking dishes, topped with extra cheese and panko before baking. Alternatively, transfer it to a pretty ceramic dish and let guests help themselves family-style, encouraging warm, casual sharing at the table.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Chicken Cordon Bleu Casserole Recipe tightly with plastic wrap or place in an airtight container. Refrigerate and enjoy within 3 to 4 days for the best taste and texture.
Freezing
This casserole freezes wonderfully. Before baking, assemble the dish as directed, cover tightly with foil and plastic wrap, then freeze. When ready to eat, thaw overnight in the refrigerator and bake as instructed, adding a few extra minutes to baking time if needed.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit for about 20 minutes or until warmed through and bubbly, to maintain the crunchy topping. Microwaving is quicker but may soften the panko crust.
FAQs
Can I use fresh chicken instead of rotisserie chicken?
Absolutely! While rotisserie chicken saves time and adds great flavor, you can poach or roast fresh chicken breasts and shred them before assembling the casserole if you prefer.
What type of ham works best for this casserole?
Any cooked ham works well — deli ham, leftover holiday ham, or ham steak cut into cubes all bring that savory, salty goodness needed for this dish.
Can I substitute the Swiss cheese for something else?
Swiss cheese has a unique nutty flavor and melts beautifully, but Gruyère or mozzarella can be good alternatives if you want a slightly different taste or texture.
Is it possible to make this casserole gluten-free?
Yes! Use a gluten-free all-purpose flour blend to thicken the sauce and substitute gluten-free breadcrumbs for the panko topping. Double-check all labels to be safe.
How can I add more veggies to this casserole?
Adding steamed broccoli florets or sautéed mushrooms between the chicken and ham layers is a delicious and easy way to boost the veggie content without losing that classic flavor.
