Step-by-Step Directions

  1. Prepare the oven and casserole dish:
    • Preheat oven to 375°F (190°C).
    • Butter a 9-by-13-inch casserole dish generously.
  2. 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.
  3. Brown the ham:
    • Add diced ham to skillet; cook over medium heat, stirring, until lightly browned (about 2 minutes).
    • Remove ham and set aside.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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

This hearty casserole makes a standout main course. Pair it with simple sides for a balanced meal:

  • Steamed or roasted vegetables: Green beans, broccoli, or asparagus add color and nutrients.
  • Light salads: A crisp green salad with vinaigrette balances the richness of the casserole.
  • Carb companions: Serve with steamed rice, egg noodles, or crusty bread to soak up the creamy sauce.

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.

More Classic Comfort Casseroles

  • Chicken and Rice Casserole: A creamy, all-in-one favorite for cozy family meals.
  • Broccoli Cheddar Bake: Cheesy, hearty, and great for sneaking in veggies.
  • Ham and Potato Gratin: The perfect use for leftover holiday ham.
