- 6 ounces ham, diced: Savory, smoky cubes that add depth and a classic cordon bleu taste.
- 6 ounces Swiss cheese, shredded: Melty, nutty cheese that binds everything with gooey goodness.
- 1 cup breadcrumbs (preferably panko): Crunchy topping that bakes to golden perfection.
- 1 cup milk: Creates a silky base for the cream of chicken soup mixture.
- 1 can (10.5 ounces) cream of chicken soup: Lends rich, creamy flavor and thickens the casserole.
- 2 tablespoons Dijon mustard: Brings bright tang and a hint of spice to the sauce.
- 1 teaspoon garlic powder: Adds savory garlic flavor without overpowering.
- 1 teaspoon onion powder: Contributes gentle onion sweetness and depth.
- ½ teaspoon black pepper: Provides subtle heat and seasoning balance.
- ½ teaspoon paprika: Infuses a smoky warmth and vibrant color.
- ¼ teaspoon salt: Enhances all the flavors for a perfectly seasoned bake.
- 2 tablespoons fresh parsley, chopped (for garnish): Brightens the dish with fresh herbal notes.

How To Make Chicken Cordon Bleu Casserole
Bringing all these ingredients together is simpler than it sounds. You’ll start by preheating the oven, then layer shredded chicken and ham with Swiss cheese before whisking up a creamy Dijon-spiked sauce. Once coated, the mixture goes into a greased casserole dish and gets topped with buttery breadcrumbs and cheese. A quick bake transforms it into a bubbly, golden masterpiece that’s ready to impress.
1. Preheat your oven to 350°F (175°C), ensuring it reaches the correct temperature before baking so your casserole cooks evenly.
2. In a large mixing bowl, combine the shredded chicken, diced ham, and half of the Swiss cheese, stirring until all pieces are well incorporated and distributed.
3. In another bowl, whisk together the milk, cream of chicken soup, Dijon mustard, garlic powder, onion powder, black pepper, paprika, and salt until smooth and lump-free.
4. Pour the soup mixture over the chicken and ham blend, then gently stir until every bit of protein is coated in the creamy sauce.
5. Transfer the coated mixture into a greased 9×13 inch casserole dish, spreading it out evenly for uniform baking.
6. In a separate bowl, combine the remaining Swiss cheese with the breadcrumbs, then drizzle in the melted butter and toss until the crumbs are evenly coated.
7. Sprinkle the breadcrumb and cheese mixture over the top of the casserole, pressing lightly so it adheres.
8. Bake for 30–35 minutes, or until the topping is golden brown and bubbly around the edges.
9. Once finished, remove from the oven and let the casserole rest for 5 minutes; this helps it set and makes serving easier.
10. Garnish with fresh chopped parsley before serving to add a pop of color and freshness.

Frequently Asked Questions
Here are some quick answers to common questions about this cozy bake:
- Q: How long does it take to prepare and cook this Chicken Cordon Bleu Casserole?
A: Prep time is about 15 minutes, which includes shredding the chicken, dicing the ham, and mixing ingredients. Bake time is 30–35 minutes at 350°F (175°C), plus a 5-minute resting period before serving, for a total of approximately 50–55 minutes from start to finish.
- Q: Can I use leftover chicken or turkey instead of rotisserie chicken?
A: Yes, leftover cooked chicken or turkey works perfectly. Just shred or dice your meat to about the same size as shredded rotisserie chicken and proceed with the recipe. Ensure the meat is fully cooked and drained of excess moisture to avoid a watery casserole.
- Q: What can I substitute for Swiss cheese if I don’t have any on hand?
A: You can swap Swiss cheese for provolone, cheddar, or Gruyère. Choose a cheese that melts well and complements the flavors. If using a sharper cheese like cheddar, consider reducing the Dijon mustard slightly to maintain balance.
- Q: How can I add vegetables to this casserole without making it soggy?
A: Lightly steam or sauté vegetables such as broccoli florets, chopped spinach, or peas until just tender. Drain any excess liquid and pat them dry before folding them into the chicken and ham mixture. This prevents added moisture from making the casserole runny.
- Q: Can I prepare this casserole ahead of time?
A: Absolutely. Assemble the casserole through step 7, then cover and refrigerate for up to 24 hours. When ready to bake, remove the cover, pop it into a preheated 350°F oven, and bake for the full 30–35 minutes or until the topping is golden and bubbly.
- Q: What’s the best way to store and reheat leftovers?
A: Store leftover casserole in an airtight container in the refrigerator for up to three days. To reheat, bake individual portions in a 350°F oven for 15–20 minutes or microwave on medium power until heated through. You can refresh the topping by adding a few extra breadcrumbs and a dot of butter before reheating.
- Q: How can I make this recipe gluten-free?
A: Replace the regular panko breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers. Double-check that your cream of chicken soup and mustard are certified gluten-free. The rest of the ingredients are naturally free of gluten.
