Key Ingredients
To build this irresistible bake, you only need a handful of simple ingredients that work together to create each creamy, crunchy layer:
- 2 cups cooked chicken, shredded or cubed: Lean protein that soaks up the creamy sauce and adds hearty texture.
- 1 cup diced ham: Savory, smoky bites that complement the chicken and deepen the flavor.
- 1 cup Swiss cheese, shredded: Melts beautifully into gooey ribbons for that classic Cordon Bleu taste.
- 1 cup breadcrumbs: Crispy topping that bakes to a golden crust and adds lovely crunch.
- 1 cup heavy cream: Creates a rich, velvety sauce that binds all the layers together.
- 1 cup chicken broth: Thins the cream slightly and adds savory depth.
- 3 large eggs: Help set the casserole into a custardy, sliceable bake.
- 1 teaspoon Dijon mustard: Adds a subtle tang that balances the richness.
- 1 teaspoon garlic powder: Infuses gentle savory warmth.
- 1 teaspoon onion powder: Boosts umami flavor with a hint of sweetness.
- 1/2 teaspoon black pepper: Provides a light, peppery kick.
- 1/2 teaspoon salt: Essential seasoning to bring all flavors forward.
- 1 tablespoon fresh parsley, chopped (for garnish): Offers a burst of fresh color and herbaceous brightness.
How To Make Chicken Cordon Bleu Casserole
Preparing this casserole is as easy as layering your ingredients and letting the oven do the work. You’ll whisk together a creamy egg mixture, fold it into the chicken and ham, then build alternating layers of breadcrumbs, protein, and cheese. A final drizzle of any leftover cream mixture ensures each bite stays moist as it bakes to bubbly perfection. Follow these detailed steps for foolproof results:
1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with cooking spray or butter to prevent sticking.
2. In a large mixing bowl, combine the shredded chicken and diced ham. Mix thoroughly so each bite is loaded with both proteins.
3. In a separate bowl, whisk together the heavy cream, chicken broth, eggs, Dijon mustard, garlic powder, onion powder, black pepper, and salt until completely smooth.
4. Gently fold the cream mixture into the chicken and ham until well combined, taking care not to overmix.
5. Spread half of the breadcrumbs evenly across the bottom of the prepared casserole dish to create a crisp base layer.
6. Layer half of the chicken and ham mixture over the breadcrumbs, then sprinkle half of the Swiss cheese on top.
7. Repeat the process with the remaining breadcrumbs, chicken and ham mixture, and Swiss cheese for alternating layers.
8. Drizzle any leftover cream mixture evenly across the top to keep the casserole moist during baking.
9. Cover the casserole dish with aluminum foil and bake for 30 minutes, locking in steam.
10. Remove the foil and bake for an additional 15–20 minutes, or until the cheese is bubbly and golden brown.
11. Once baked, remove the casserole from the oven and let it cool for a few minutes before serving to set.
12. Garnish with fresh chopped parsley for a pop of color and extra flavor.
Serving Suggestions
This hearty casserole pairs beautifully with simple sides that balance its richness. Here are four tasty ways to serve it:
- Fresh green salad: Toss crisp mixed greens, cucumber ribbons, and cherry tomatoes with a light vinaigrette to cut through the creaminess.
- Steamed vegetables: Brighten the plate with steamed broccoli or green beans, lightly seasoned with salt and a squeeze of lemon.
- Garlic bread: Warm crusty garlic bread or breadsticks make perfect vehicles for scooping up any leftover sauce.
- Chilled white wine: A glass of Sauvignon Blanc or Chardonnay complements the cheesy, creamy flavors and adds a refreshing contrast.

Frequently Asked Questions
Got questions? I’ve got answers to your most common queries:
- How long does it take to prepare and bake the Chicken Cordon Bleu Casserole?
Preparation takes about 20–25 minutes, which includes shredding or cubing the chicken, dicing the ham, whisking the cream mixture, and layering the ingredients. Baking time is 45–50 minutes in a 350°F (175°C) oven—30 minutes covered with foil, plus an additional 15–20 minutes uncovered until the cheese is bubbly and golden. Allow 5–10 minutes of resting time before serving.
- Can I assemble the casserole ahead of time?
Yes. You can layer the casserole up to 24 hours in advance. Cover it tightly with plastic wrap or foil and store it in the refrigerator. When ready to bake, remove the cover, top with fresh foil if needed, and bake at 350°F for the full baking time, adding a few extra minutes if it’s still very cold in the center.
- How can I make this dish gluten-free?
Simply substitute the regular breadcrumbs with your favorite gluten-free breadcrumbs. Ensure any chicken broth or other packaged ingredients you use are labeled gluten-free. The casserole’s texture and flavor remain very similar with this swap.
- What are some suitable substitutions or additions?
You can swap cooked turkey for chicken for a lighter flavor, or use diced cooked pork tenderloin. To boost nutrition, stir in vegetables such as steamed broccoli florets, sautéed spinach, or diced bell peppers when you combine the chicken and ham. Adjust seasoning slightly to taste if the veggies add moisture or sweetness.
- How should I store and reheat leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions on a baking sheet, cover loosely with foil, and warm in a 350°F oven for 10–15 minutes until heated through. You can also microwave single servings on medium power for 1–2 minutes, stirring halfway.
- Can I reduce the fat or calories in this casserole?
You can lighten the dish by using half-and-half instead of heavy cream or by swapping one cup of cream for more chicken broth. Choose reduced-fat Swiss cheese and consider using an egg white instead of a whole egg. Keep in mind the casserole may be less rich and slightly less creamy in texture.
- Why is Dijon mustard included, and can I omit it?
Dijon mustard adds a subtle tang and depth that balances the richness of cream, cheese, and ham. If you don’t have Dijon, you can use whole-grain mustard or a teaspoon of dry mustard powder. Omitting mustard entirely will still work but may result in a milder overall flavor.
