- Preheat and prep: Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or a bit of oil.
- Make the sauce base: In a mixing bowl, whisk cream cheese, heavy cream, Dijon, and mayonnaise until smooth. If the cream cheese is stiff, microwave it for 10–15 seconds to soften before whisking.
- Season the sauce: Stir in garlic powder, onion powder, lemon juice, pepper, salt, and paprika.Taste and adjust salt or lemon as needed. The sauce should be tangy and well-seasoned.
- Layer the chicken: Spread the cooked chicken evenly in the baking dish. Sprinkle a pinch of salt and pepper if your chicken is unseasoned.
- Add the ham: Scatter the chopped ham over the chicken in an even layer.
- Add the Swiss: Place Swiss slices or an even layer of shredded Swiss over the ham.This helps lock in moisture and gives that classic cordon bleu flavor.
- Pour the sauce: Spoon the sauce over the top and spread it gently into an even layer so every bite gets creamy coverage.

- Bake: Place the dish in the center of the oven and bake for 20–25 minutes until the edges are bubbling and the top is golden. If you want extra color, broil for 1–2 minutes at the end, watching closely.
- Rest and serve: Let it rest for 5 minutes so the sauce sets.Garnish with parsley. Serve with a green salad, roasted broccoli, or sautéed spinach.
What Makes This Special
This casserole keeps the heart of cordon bleu—chicken, ham, Swiss cheese, and a creamy Dijon sauce—while skipping the breadcrumbs. The sauce uses cream cheese and a touch of heavy cream for richness without flour.
A quick Parmesan-almond topping gives you a toasty finish with minimal carbs.
It’s also flexible. Use leftover rotisserie chicken or cook fresh. Swap cheeses if you like.
The whole dish comes together in one baking dish and reheats well for lunches all week.

Storage Instructions
- Refrigerator: Cool completely, then cover tightly. Store up to 4 days.
- Freezer: Wrap well and freeze up to 2 months.
For best texture, freeze before baking; thaw overnight, then bake as directed.

Benefits of This Recipe
- Low in carbs, high in satisfaction: You get creamy, cheesy comfort without the breading.
- Meal-prep friendly: Makes multiple servings and reheats well.
- Quick assembly: Using cooked chicken cuts down prep time on busy nights.
- Flexible: Easy to adjust for different tastes, cheeses, or add-ins like spinach or mushrooms.
- Gluten-free option: No flour or breadcrumbs needed.
What Not to Do
- Don’t skip seasoning: The sauce needs enough salt, pepper, and acidity to shine. Taste it before assembling.
- Don’t use watery chicken: If your chicken is very juicy, pat it dry so the casserole doesn’t get soupy.
- Don’t overbake: Baking too long can make the cheese oily and the chicken dry.
Pull it once the top is golden and bubbly.
- Don’t overload the topping: Too much almond flour topping can taste heavy. Keep it light and even.
- Don’t skip the rest: A short rest helps the sauce thicken for cleaner slices.
Alternatives
- Cheese swaps: Try Gruyère or provolone for a slightly different profile. Add a little mozzarella for extra melt if desired.
- Sauce tweaks: Replace lemon juice with 1 teaspoon white wine vinegar, or add 1 teaspoon Worcestershire for depth.
- Protein options: Use turkey instead of chicken, or Canadian bacon instead of ham for a leaner cut.
- Veggie add-ins: Layer in steamed broccoli florets, sautéed mushrooms, or wilted spinach under the sauce.
Pat veggies dry first.
- Dairy-light version: Swap half the cream cheese for cottage cheese blended smooth, and use half-and-half in place of cream.
- No-nut topping: Skip almond flour and use only Parmesan, or crushed pork rinds for crunch while keeping carbs low.
FAQ
How many carbs are in a serving?
Exact carbs depend on your specific brands and portions, but a typical serving of this casserole lands around 4–6 net carbs. Use a nutrition calculator with your ingredients to get a precise number.
Can I make it ahead?
Yes. Assemble up to the topping, cover, and refrigerate for up to 24 hours.
Add the topping right before baking for best texture. You may need to add 5–10 minutes to the bake time if starting from cold.
What’s the best chicken to use?
Shredded rotisserie chicken is fast and flavorful. Leftover roasted or poached chicken works too.
Aim for bite-sized pieces so every forkful has chicken, ham, and cheese.
Can I make this without mayonnaise?
Yes. Replace the mayo with an extra 2 tablespoons of heavy cream or sour cream. The sauce will still be creamy and tangy.
How do I keep it from being too salty?
Choose lower-sodium ham, taste the sauce before salting, and go light on added salt until after baking.
You can also balance salt with a bit more lemon juice.
What if I don’t have almond flour?
Use crushed pork rinds, extra Parmesan, or skip the topping entirely. The casserole will still brown nicely from the cheese.
Can I cook the chicken from raw in the casserole?
For food safety and texture, it’s better to use pre-cooked chicken. If starting from raw, cut into small cubes, season, and pan-sear until cooked through before assembling.
How do I avoid a greasy top?
Don’t overbake, and use quality Swiss or Gruyère that melts cleanly.
Let the casserole rest so the fats reabsorb into the sauce instead of pooling.
Is this keto-friendly?
Yes. With low carbs, moderate protein, and higher fat from cheese and cream, it fits well into a keto plan. Pair with low-carb veggies to keep macros in line.
