Ingredients
Method
- Heat the oven: Preheat to 375°F (190°C). Grease a 9x13-inch baking dish with butter or avocado oil.
- Prep the protein: Add the cooked chicken and chopped ham to the baking dish. Toss to distribute evenly.
- Make the sauce: In a bowl, whisk the softened cream cheese, heavy cream, Dijon, garlic, onion powder, lemon juice, salt, and pepper until smooth. If it’s too thick, add a splash more cream.
- Combine: Pour the sauce over the chicken and ham. Sprinkle 1 1/2 cups of shredded Swiss evenly over the top.
- Mix the topping: Stir the melted butter with the crushed pork rinds (or almond flour) and Parmesan until crumbly.
- Top and bake: Scatter the topping over the casserole. Bake for 20–25 minutes, until the edges bubble and the top is golden.
- Finish with cheese: Sprinkle the remaining 1/2 cup Swiss over the top and bake 5 more minutes to melt.
- Rest and garnish: Let it sit 5–10 minutes to set. Garnish with parsley if you like.
- Serve: Pair with a simple green salad or roasted broccoli to keep it low-carb and balanced.
What Makes This Special
This casserole captures the spirit of chicken cordon bleu—chicken, ham, Swiss, and a touch of Dijon—without stuffing or breading. It keeps things keto by swapping traditional breadcrumbs for a crunchy, low-carb topping and using a cream-based sauce.
The flavor is bold but balanced, and the texture is creamy with a crisp, cheesy finish. It’s the kind of meal that makes eating low-carb feel anything but restrictive.
- Keto-friendly: No breading, no flour, just naturally low-carb ingredients.
- Easy prep: Bakes in one dish and uses cooked chicken, so it comes together fast.

What Not to Do

FAQ
Can I make this ahead?
Yes.
Assemble the casserole up to the topping, cover, and refrigerate for up to 24 hours. Add the topping right before baking to keep it crisp. You may need to add 5–10 minutes to the bake time if starting cold.
What’s the best ham to use?
Choose a no-sugar-added, nitrate-free deli ham if possible.
Thicker slices hold texture better in the casserole, but standard deli slices work fine when chopped.
Is there a substitute for heavy cream?
You can use half-and-half, but the sauce will be slightly thinner and higher in carbs. For a lower-carb swap, try unsweetened almond milk plus 1–2 ounces extra cream cheese to thicken.
How do I make it even lower in carbs?
Use crushed pork rinds instead of almond flour for the topping and stick to Swiss or Gruyère, which are naturally low in carbs. Also avoid adding starchy vegetables.
Can I use raw chicken?
You can, but you’ll need to cube it small and cook it in a skillet first to avoid excess moisture and uneven cooking.
This recipe is designed for cooked chicken to keep things fast and consistent.
Why is my sauce grainy?
Cold cream cheese can clump. Soften it fully and whisk with cream until smooth before adding to the dish. A quick blend with an immersion blender also fixes a lumpy sauce.
What can I use instead of pork rinds?
Finely ground almonds, almond flour, or crushed keto crackers work well.
Mix with butter and Parmesan to keep the topping crisp and flavorful.
How many servings does this make?
It typically yields 6–8 servings, depending on portion size. For meal prep, divide the casserole into individual containers after baking and cooling.
Can I make it dairy-free?
It’s tough to replicate the classic flavor dairy-free, but you can try coconut cream, dairy-free cream cheese, and a meltable vegan cheese. Expect a different, still tasty result.
What should I serve with it?
Keep sides simple and low-carb: a crisp green salad, roasted asparagus, sautéed spinach, or cauliflower mash.
The casserole is rich, so fresh, bright sides balance it nicely.
