This adapted Chicken Cordon Bleu Casserole replaces traditional ham with smoked turkey for a lighter yet flavorful alternative that maintains the dish’s signature taste profile. The smoked turkey provides the essential savory, cured meat element while offering a milder flavor that allows the Swiss cheese and Dijon mustard to shine. This substitution creates a more accessible version for those who prefer poultry over pork while delivering the same satisfying comfort food experience.
Smoked turkey works particularly well in this application because it shares ham’s smoky characteristics while being leaner and more readily available. The result is a casserole that feels familiar yet offers a subtle twist that broadens its appeal to different dietary preferences.

Step-by-Step Instructions
Prepare the Base
Preheat oven to 350°F and spray a 9×13-inch casserole dish with cooking spray. Layer the shredded rotisserie chicken evenly across the bottom of the dish, then distribute the diced smoked turkey evenly over the chicken layer.
Create the Cheese Sauce
In a saucepan over medium heat, melt butter completely. Sprinkle flour over melted butter and cook for 1-2 minutes, whisking constantly, until mixture becomes dry and clumpy to eliminate raw flour taste.
Build the Sauce
Gradually whisk in milk, maintaining constant whisking to prevent lumps. Add Dijon mustard, lemon juice, garlic powder, and salt. Simmer for 3-5 minutes, whisking constantly, until mixture thickens enough to coat the back of a spoon.
Finish with Cheese
Remove from heat and stir in Swiss and Parmesan cheeses until completely melted and smooth. Taste and adjust salt as needed, keeping in mind that smoked turkey may add some saltiness. Pour sauce evenly over the turkey and chicken layers.
Add the Topping
In a small bowl, combine Panko breadcrumbs with melted butter and optional thyme, mixing until breadcrumbs are evenly coated. Sprinkle mixture evenly over the cheese sauce layer.
Bake to Golden Brown
Bake uncovered for 30-35 minutes until breadcrumbs are golden brown and casserole bubbles around the edges. Allow to cool for 5-10 minutes before serving to let the sauce set properly.
Recipe Notes & Tips
Turkey Selection – Choose quality smoked turkey from the deli counter rather than packaged lunch meat for better flavor and texture.
Salt Adjustment – Smoked turkey varies in saltiness, so taste the sauce before adding full amount of salt.
Dicing Technique – Cut turkey into 1/2-inch cubes for even distribution and proper bite size.
Moisture Consideration – Smoked turkey is typically drier than ham, so ensure sauce covers all protein layers completely.
Herb Pairing – Thyme and sage complement turkey particularly well if adding herbs to the topping.
