Step-by-Step Directions
- Prepare the oven and casserole dish:
- Preheat oven to 375°F (190°C).
- Butter a 9-by-13-inch casserole dish generously.
- Season and sear the chicken cutlets:
- Pat cutlets dry; season all sides with 1 teaspoon salt and 1/2 teaspoon pepper.
- Heat a large skillet over medium; melt 1 teaspoon butter.
- Sear 4 cutlets at a time, 2–3 minutes per side (just until browned, not cooked through). Repeat with remaining chicken and an additional teaspoon of butter as needed.
- Transfer seared cutlets to a plate; reserve skillet drippings.
- Brown the ham:
- Add diced ham to skillet; cook over medium heat, stirring, until lightly browned (about 2 minutes).
- Remove ham and set aside.
- Prepare the cheese sauce:
- Add 3 Tbsp butter to the skillet; melt over medium heat.
- Sprinkle in flour; cook, whisking constantly, for 1 minute.
- Slowly whisk in milk and chicken broth. Add cayenne if using.
- Bring to a simmer and cook, whisking, until thickened (2–3 minutes). Remove from heat.
- Whisk in Dijon mustard, then add 1/2 cup Swiss and 1/2 cup mozzarella. Stir until melted and smooth.
- Season with remaining 1/2 tsp salt and 1/4 tsp pepper.
- Assemble the casserole:
- Spread 1 1/2 cups of cheese sauce in the bottom of prepared dish.
- Arrange seared chicken cutlets over the sauce, slightly overlapping.
- Spoon the remaining sauce evenly over the chicken.
- Scatter browned ham, then top with remaining 1/2 cup Swiss and 1/2 cup mozzarella.
- Make and add the topping:
- In a small bowl, toss panko breadcrumbs with chopped parsley and remaining 1 Tbsp melted butter.
- Sprinkle evenly over the top of the casserole.
- Bake:
- Bake at 375°F for 25–30 minutes, until bubbly and golden, and chicken is cooked through.
- Garnish with more chopped parsley before serving.
- Optional serving:
- Serve alongside steamed rice and green beans for a complete and colorful meal.
Tips and Tricks
- Making chicken cutlets: If you can’t find pre-cut cutlets, slice a boneless, skinless chicken breast in half horizontally for two thinner pieces. This ensures quick, even cooking and tender texture.
- Cheese choices: Swiss cheese is classic, but a mix with mozzarella adds melting quality. For a richer flavor, use Gruyère or even provolone.
- Make ahead: Assemble up to one day in advance (without the panko topping), refrigerate, then add topping and bake just before serving.
- Crispier topping: For extra crunch, toast the panko in a dry skillet before sprinkling over the casserole.
- Shortcut ideas: Use rotisserie chicken and diced packaged ham for a true time saver, though flavor and texture may vary.
- Portion planning: This recipe serves 6–8 as a main dish.
What to Serve With Chicken Cordon Bleu Casserole

FAQ: Frequently Asked Questions
Can I use rotisserie or pre-cooked chicken?
Yes, you can substitute rotisserie or leftover cooked chicken; reduce the searing step and proceed with layering. Flavor is most intense with freshly seared cutlets.
What kind of ham should I use?
Diced cooked ham, deli-sliced ham, or even leftover holiday ham are all appropriate. Opt for a milder, less salty variety for balance.
Can I freeze Chicken Cordon Bleu Casserole?
The casserole can be assembled and frozen (without the breadcrumb topping) for up to 2 months. Thaw overnight in the fridge, add panko, and bake as instructed, adding some extra time to ensure it’s heated through.
How do I prevent a soggy topping?
Wait to add the buttered panko topping right before baking. For added crunch, toast breadcrumbs briefly in a dry skillet before assembling.
Can this be made ahead?
Yes, you can assemble the casserole (without panko topping) up to 1 day ahead. Refrigerate covered; add topping and bake just before serving.
Is there a gluten-free option?
Substitute all-purpose flour and panko with gluten-free varieties. Watch for hidden gluten in prepared ham or broth.
Pro Tips & Serving Suggestions
- Garnish generously: Chopped curly or flat-leaf parsley adds color and fresh flavor.
- Make it extra creamy: Stir a little sour cream or heavy cream into the sauce for richer texture.
- Customize your cheese blend: Try Gruyère, Havarti, or even sharp cheddar for a unique spin.
- Vegetable add-ins: For heartier fare, add thin layers of cooked spinach or steamed broccoli between chicken and sauce.
Storage & Leftovers
Leftover casserole keeps well in the refrigerator for up to 3 days, tightly covered. Reheat individual servings in the microwave or oven until heated through. Note that the crispy topping will be soft the next day; for best results, re-toast under the broiler for a few minutes after reheating.
Recipe Variations
- Lighter version: Use part-skim mozzarella and reduced-fat Swiss cheese. Substitute whole milk with low-fat milk or even unsweetened dairy-free milk for calories savings.
- Low-carb alternative: Omit the panko topping, or use crushed pork rinds as a keto-friendly substitute.
- Spicier twist: Add a dash more cayenne or stir in chopped jalapeños for heat lovers.
