Ingredients List

This casserole builds the iconic Cordon Bleu flavor profile through smart layering and a luxurious homemade sauce.

For the Casserole Base:

• 2 lbs boneless, skinless chicken breasts or thighs, cut into 1-inch cubes
• 1 tablespoon olive oil
• 8 oz (about 2 cups) cooked ham, diced (use thick-cut deli ham or leftover baked ham)
• 8 oz (about 2 cups) Swiss cheese, shredded (Gruyère is a fantastic upscale substitute)
• 1 (16 oz) bag frozen mixed vegetables (like peas & carrots), thawed and drained (optional, for a veggie boost)

For the Creamy Sauce:

• 4 tablespoons unsalted butter
• 1 medium yellow onion, finely diced
• 3 cloves garlic, minced
• ⅓ cup all-purpose flour
• 2 cups low-sodium chicken broth
• 1 cup heavy cream or whole milk
• 2 tablespoons Dijon mustard
• 1 tablespoon fresh lemon juice
• 1 teaspoon dried thyme
• ½ teaspoon paprika
• Salt and freshly ground black pepper to taste

For the Crispy Topping:

• 1 ½ cups panko breadcrumbs
• ½ cup grated Parmesan cheese
• 3 tablespoons unsalted butter, melted
• 2 tablespoons fresh parsley, chopped

Smart Substitutions:

• Chicken: Use a rotisserie chicken to save time—shred about 4 cups of meat.
• Ham: Substitute with cooked turkey ham, diced Canadian bacon, or omit for a chicken & Swiss casserole.
• Swiss Cheese: Emmental, Jarlsberg, or a mild white cheddar work well.
• Heavy Cream: Use half-and-half or evaporated milk for a lighter sauce.
• Gluten-Free: Use a 1:1 gluten-free flour blend and gluten-free panko.

Timing

• Preparation Time: 20 minutes
• Cooking Time: 35 minutes
• Total Time: 55 minutes

This Creamy Chicken Cordon Bleu Casserole Recipe streamlines the process dramatically, requiring just 55 minutes from start to finish. That’s approximately 40% faster than preparing traditional, individual Chicken Cordon Bleu parcels, with the added benefit of being a complete one-dish meal that feeds a crowd.

Step-by-Step Instructions

Step 1: Cook and Prepare the Chicken

Preheat your oven to 375°F (190°C). This is the perfect temperature for a gentle, even bake that cooks the chicken through without curdling the creamy sauce. Pat your cubed chicken dry and season lightly with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Cook the chicken in a single layer for 5-7 minutes, just until no longer pink on the outside. It will finish cooking in the oven. Transfer to a plate. This quick sear adds flavor and ensures the chicken stays tender.

Step 2: Build the Luxurious Cream Sauce (The Soul of the Dish)

In the same skillet, reduce heat to medium. Melt the 4 tablespoons of butter. Add the diced onion and cook until soft and translucent, about 5 minutes. Add the minced garlic and cook for 60 seconds until fragrant. Sprinkle the flour over the onions and garlic, stirring constantly to form a paste (this is called a roux). Cook for 2 minutes to eliminate the raw flour taste.

Slowly whisk in the chicken broth, followed by the heavy cream, ensuring no lumps form. Bring to a gentle simmer, whisking frequently. The sauce will thicken noticeably. Remove from heat and whisk in the Dijon mustard, lemon juice, dried thyme, and paprika. Taste and season generously with salt and pepper. This rich, velvety sauce is what binds the casserole and delivers the classic Cordon Bleu flavor.

Step 3: Layer the Casserole with Flavor

In a 9×13 inch baking dish, combine the partially cooked chicken, diced ham, and thawed vegetables (if using). Pour the creamy sauce over everything and gently stir to ensure every piece is coated. Sprinkle the shredded Swiss cheese evenly over the top.

Step 4: Create the Crispy, Golden Topping

In a small bowl, mix the panko breadcrumbs, grated Parmesan, melted butter, and chopped parsley until the crumbs are evenly moistened. Sprinkle this mixture in an even layer over the cheese. This topping will bake into an irresistible, buttery, crispy crust that contrasts beautifully with the creamy filling below.

Step 5: Bake to Bubbly Perfection

Place the casserole in the preheated oven and bake, uncovered, for 30-35 minutes. You’re looking for the filling to be bubbling vigorously around the edges and the topping to be a deep, golden brown. If the top browns too quickly, tent it loosely with aluminum foil.

Step 6: Rest and Serve

Once out of the oven, let the casserole rest for 10 minutes before serving. This crucial step allows the sauce to thicken slightly and makes serving much cleaner. Scoop generous portions onto plates or into shallow bowls.

Nutritional Information

Per Serving (based on 8 servings):

Nutritional Highlights: This Creamy Chicken Cordon Bleu Casserole Recipe is a substantial source of high-quality protein from both chicken and ham. The Swiss cheese provides a significant amount of calcium. For a lighter version, using lower-fat dairy, reducing butter, and increasing vegetables can adjust the profile while maintaining core flavors.

Healthier Alternatives for the Recipe

Enjoy the comforting taste while aligning with various dietary preferences.

For a Lighter Version:

• Use skinless chicken breast and low-sodium ham.
• Replace the heavy cream with 2% milk or a blend of milk and Greek yogurt (add yogurt off-heat at the end).
• Reduce the butter in the sauce to 2 tbsp and use just 1 tbsp in the topping.
• Increase the proportion of mixed vegetables to add volume and fiber.

For Dietary Adaptations:

• Gluten-Free: Use a certified GF flour blend and gluten-free panko or crushed gluten-free crackers for the topping.
• Lower Carb/Keto: Omit the flour. Thicken the sauce with 4 oz of cream cheese. Replace panko topping with a mix of crushed pork rinds and Parmesan.
• Dairy-Free: Use vegan butter, a dairy-free cream alternative (like cashew cream), and dairy-free cheeses.
• Lower Sodium: Use no-salt-added broth, reduce or omit added salt, and choose low-sodium ham.

Serving Suggestions

This rich casserole is a complete meal, but it shines alongside simple, complementary sides.

• The Classic Pairing: Serve with a simple green salad dressed with a tangy vinaigrette to cut through the richness. Buttered egg noodles or mashed potatoes are also perfect for soaking up the extra sauce.
• With Crusty Bread: A loaf of warm, crusty French bread or rolls is ideal for scooping up every last bit of creamy goodness from the plate.
• For a Lighter Plate: Serve alongside steamed green beans, roasted asparagus, or a bright, citrusy broccoli salad.
• Perfect for Potlucks: This casserole travels and holds heat well, making it an ideal dish to bring to gatherings. Just reheat covered until warm.

Common Mistakes to Avoid

• Using Raw Chicken Without Searing: Adding raw chicken directly to the casserole can result in uneven cooking and excess water diluting the sauce. A quick sear locks in juices and flavor.
• Not Cooking the Roux Long Enough: If the flour isn’t cooked for a full 1-2 minutes in the butter, your sauce can have a pasty, raw flour taste. Cook until it smells nutty.
• Overbaking the Casserole: Baking for too long or at too high a temperature can cause the dairy in the sauce to separate or become grainy. 375°F is the sweet spot.
• Skipping the Resting Time: Cutting into the casserole immediately sends all the creamy sauce running. Letting it set for 10 minutes is key to the perfect serving consistency.
• Using Pre-Shredded Cheese: Pre-shredded cheeses contain anti-caking agents that prevent them from melting as smoothly. Shredding your own Swiss cheese ensures a velvety, cohesive melt.

Storing Tips for the Recipe

• Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days.
• Freezing: Assemble the casserole without the panko topping. Cover tightly and freeze for up to 2 months. Thaw overnight in the refrigerator, add the topping, and bake as directed, adding 10-15 minutes to the bake time.
• Reheating: Reheat individual portions in the microwave, covered, stirring halfway. For larger amounts, reheat in a covered dish in the oven at 350°F until warmed through. Adding a splash of broth can help revive the sauce.
• Make-Ahead: You can assemble the entire casserole (with topping) 1 day in advance. Cover and refrigerate. Bake as directed, adding 5-10 minutes to the bake time since it will be cold.

Conclusion

This Creamy Chicken Cordon Bleu Casserole Recipe delivers all the luxurious flavor of the classic dish in an easy, comforting bake. With tender chicken, ham, Swiss cheese, and a rich sauce under a crispy topping, it’s a guaranteed crowd-pleaser for any night of the week.

FAQs

Can I use a rotisserie chicken?
Absolutely! This is a fantastic time-saver. Shred the meat from one rotisserie chicken (about 4 cups) and skip the searing step. Simply mix the shredded chicken with the ham and proceed with the sauce and assembly.

What can I use instead of panko for the topping?
Crushed Ritz crackers, crushed cornflakes, or even crushed butter crackers make a delicious, buttery topping. For a more traditional twist, use seasoned breadcrumbs.

My sauce seems too thin. How can I thicken it?
If your sauce hasn’t thickened after simmering, create a slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water. Whisk this into the simmering sauce and cook for 1-2 minutes until thickened.

Can I make this casserole in a slow cooker?
Yes, with adjustments. Sear the chicken. Add chicken, ham, veggies, and sauce to the slow cooker. Cook on LOW for 3-4 hours. Add cheese and topping for the last 30 minutes of cooking, uncovered, to melt and crisp.

Is it possible to make this dish ahead and freeze it?
Yes, it freezes beautifully. Assemble the casserole without the breadcrumb topping. Wrap tightly and freeze. Thaw overnight in the fridge, add the topping, and bake as directed, adding extra time as needed.
