This Chicken Cordon Bleu Casserole brings all the irresistible flavors of classic chicken cordon bleu to an easy, comforting baked dish. Tender chicken, savory ham, melty Swiss cheese, and a creamy Dijon-garlic sauce come together beneath a golden, bubbly cheese topping.
With plenty of protein and no traditional breadcrumbs, this low-carb chicken casserole is a satisfying choice for busy weeknights. It’s creamy, cheesy, cozy, and simple enough to prepare without the fuss of stuffing and rolling individual chicken breasts.
Can This Chicken Cordon Bleu Casserole Support Weight Loss Goals?
This casserole can fit into a balanced weight-management eating pattern because chicken breast provides a substantial amount of protein, which can contribute to a satisfying meal. Keeping chicken as the primary ingredient while using measured portions of cream, cheese, and ham helps balance the recipe.
For a lighter version, choose skinless chicken breast, lean ham, reduced-fat cheese, and Greek yogurt. Weight-management results depend on overall calorie intake, food choices, activity, and individual needs rather than any single recipe.
Does This Recipe Fit a High-Protein Lifestyle?
Yes, this casserole fits well into a high-protein lifestyle, with chicken breast providing most of the protein and ham, Swiss cheese, Parmesan, and Greek yogurt adding more. Since it contains no traditional breadcrumbs or flour, it remains relatively low in carbohydrates. This version provides approximately 43g of protein and 6g net carbs per serving, although exact values vary by ingredient brands. Pair it with non-starchy vegetables for a balanced, lower-carb meal.

My Personal Experience
- The creamy sauce is what makes this dish special.
The garlic-Dijon sauce coats the chicken beautifully and gives the casserole a rich, savory flavor.
It stays creamy while the cheese on top becomes golden and bubbly. - Ham and Swiss cheese are a perfect match.
The salty ham balances the mild, nutty flavor of melted Swiss cheese.
Every serving gets that classic chicken cordon bleu taste without complicated preparation. - The casserole feels wonderfully comforting.
Tender chicken combined with creamy sauce and melted cheese makes this ideal for cozy dinners.
A crisp green salad or roasted broccoli adds a fresh contrast. - It’s much easier than traditional cordon bleu.
Instead of stuffing and rolling each chicken breast, everything is layered into one baking dish.
That makes this recipe especially practical on busy evenings.

Common Mistakes to Avoid
- Overcooking the chicken:
Chicken breast can become dry if baked too long, so check the internal temperature rather than relying only on cooking time. - Making the sauce too thin:
Too much broth or cream can leave excess liquid in the casserole, so measure carefully. - Boiling the Greek yogurt:
Adding yogurt over very high heat can cause the sauce to separate, so stir it in gently after reducing the heat. - Adding too much salt:
Ham, Swiss cheese, Parmesan, and broth can already be salty, so taste the sauce before adding additional salt.
Required Equipment
- 9 × 13-inch baking dish — provides enough surface area for even cooking and golden cheese browning.
- Large skillet — allows the chicken and creamy sauce to develop flavor before baking.
- Whisk — creates a smooth, lump-free sauce.
- Mixing bowl — makes seasoning and coating the chicken simple.
- Sharp knife — makes it easy to cut chicken and ham into evenly sized pieces.
- Meat thermometer — confirms the chicken reaches a safe internal temperature.
Storage Instructions
Refrigerator: Allow leftovers to cool before transferring them to an airtight container, or cover the casserole dish tightly. Refrigerate for up to 4 days.
Freezer: Cool completely, then portion into freezer-safe airtight containers or wrap the casserole tightly before freezing. For best quality, use within 2–3 months.
Reheating: Reheat individual portions in the microwave in 60–90 second intervals until hot. For larger portions, cover with foil and warm in a 325°F (165°C) oven for 15–20 minutes.
Gentle reheating is preferable because very high temperatures can cause the creamy dairy sauce to separate.

📝 Ingredients
Chicken & Filling
- 2 lb (900g) boneless, skinless chicken breasts, cut into bite-size pieces
- 6 oz (170g) lean ham, chopped
- 1 cup (100g) shredded Swiss cheese
- ½ cup (50g) shredded mozzarella cheese
- 1 tablespoon olive oil
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- ¼ teaspoon black pepper
Creamy Dijon Sauce
- 1 cup (240ml) heavy cream
- ½ cup (120ml) low-sodium chicken broth
- ½ cup (120g) plain Greek yogurt
- 2 tablespoons Dijon mustard
- 2 cloves garlic, minced
- ½ teaspoon Italian seasoning
- ¼ teaspoon black pepper
- ¼ cup (25g) finely grated Parmesan cheese
Ingredient notes: Use thick Greek yogurt for the smoothest sauce. Lean ham and reduced-fat cheese can be used to lower calories, while low-sodium ham and broth can help control sodium.
Directions
- Preheat the oven.
Heat the oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish. - Season the chicken.
Place the chicken pieces in a large bowl. Add olive oil, garlic powder, paprika, and black pepper, then toss until evenly coated. - Brown the chicken.
Heat a large skillet over medium-high heat. Add the chicken and cook for 4–5 minutes, turning occasionally. The outside should be lightly browned; the chicken does not need to be completely cooked at this stage. - Sauté the garlic.
Reduce the heat to medium-low and add the minced garlic. Cook for approximately 30 seconds, just until fragrant. - Make the sauce.
Add chicken broth and heavy cream. Whisk gently and simmer over medium-low heat for 3–4 minutes, until the mixture begins to thicken slightly. - Season the sauce.
Stir in Dijon mustard, Italian seasoning, black pepper, and Parmesan. Cook for another 1–2 minutes, stirring until the Parmesan melts. - Add Greek yogurt.
Remove the skillet from direct heat and let the sauce cool for approximately 1 minute. Stir in the Greek yogurt until smooth. Do not allow the yogurt mixture to boil. - Assemble the casserole.
Transfer the browned chicken to the prepared baking dish. Spread the chopped ham evenly over the chicken. - Add the creamy sauce.
Pour the sauce evenly over the chicken and ham, making sure the pieces are well coated. - Add the cheese topping.
Sprinkle the Swiss cheese and mozzarella evenly over the surface. - Bake.
Bake uncovered at 375°F (190°C) for 20–25 minutes, until the sauce is bubbling and the cheese is melted and lightly golden. - Check for doneness.
Insert a meat thermometer into the thickest piece of chicken. It should reach 165°F (74°C). - Rest the casserole.
Remove from the oven and let it rest for 5–10 minutes. The sauce should thicken slightly as it stands. - Serve.
Garnish with fresh parsley if desired and serve hot alongside your favorite low-carb vegetables.
High-protein cooking tip: Choose lean chicken breast and a Greek yogurt with a high protein content per serving. Keeping chicken as the main ingredient helps maintain the recipe’s protein-forward profile without relying solely on cheese and cream.
