This chicken cordon bleu casserole recipe is a healthier take on the chicken kiev and cordon bleu I grew up eating, without all the fuss of pounding and wrapping individual pieces of chicken. This healthy meal comes together much faster than the original, it’s naturally low carb, and it even has a hidden veggie in there — but it also has the same cheesy, creamy comfort food vibe that the whole family can agree on.

What Is Cordon Bleu Casserole?

Chicken cordon bleu casserole combines all of the classic flavors of chicken cordon bleu — the breaded chicken dish stuffed with ham and cheese, with the French name but originating from Switzerland — in an easy, healthy casserole.

This dish is so comforting, I even included it in my hardcover Easy Keto Carboholics’ Cookbook, which is dedicated to making healthy, low carb versions of carb-filled comfort foods. Once you try this keto chicken cordon bleu casserole recipe, I think you’ll see why I had to include it in the book, why it’s one of my favorite low carb dinners, AND why you don’t have to be keto to find it delicious.

Ingredients You’ll Need

This section explains how to choose the best ingredients for easy chicken cordon bleu casserole, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

• Cauliflower – The hidden veggie! Cut the cauliflower into same-sized florets, so they cook evenly. Feel free to include any other vegetables you like here that work well when roasted.
• Avocado Oil – Use avocado oil for best flavor and nutrition, but you can also use your preferred vegetable oil.
• Sea Salt & Black Pepper – The amount of salt in the recipe assumes that your shredded chicken had salt added before cooking. If it’s completely unsalted, you can add more salt to taste before baking the casserole.

• Heavy Cream – This gives the casserole rich and creamy flavor. I don’t recommend using milk, as the sauce will be too runny, but full-fat coconut milk (from a can) could work as a swap.
• Sour Cream – Use full-fat sour cream for best flavor. Mayonnaise works as a substitute if needed, but the flavor will be different.
• Dijon Mustard – This gives the casserole a little zing and pairs wonderfully with the ham. Yellow mustard is okay to use, but it may be too strong; the flavors work best with Dijon.
• Garlic – Use fresh garlic for best flavor or jarred garlic for convenience. If you need to, you can substitute 1/2 teaspoon garlic powder instead.
• Chicken – It needs to be cooked. You can make your own shredded chicken using chicken breasts or thighs. Other convenience options include rotisserie chicken, packaged precooked chicken breast, diced baked chicken breast, or any leftover chicken you have.

• Ham – Use deli ham or leftover keto glazed ham.
• Swiss Cheese – Buy shredded cheese for convenience, or shred your own for best flavor. Swiss is the classic choice, but you can also mix in Gruyere, mozzarella, or even pepper jack. If you have cheese slices on hand, you could also melt those on top of the casserole instead of using shredded.
• Pork Rinds – These are optional, but add a nice crunch to the casserole, like breadcrumbs or crackers would. If making this for a family and you’re not concerned about the carbs, panko breadcrumbs are fine to substitute.

How To Make Chicken Cordon Bleu Casserole

This section shows how to make keto cordon bleu chicken casserole with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

1. Roast cauliflower. Season cauliflower with oil, sea salt, and pepper and spread out on a baking sheet. Roast until golden.

2. Mix sauce. In a large bowl, whisk together cream, sour cream, Dijon mustard, garlic, and half of the shredded cheese.
3. Add main ingredients. Fold in shredded chicken, ham, and roasted cauliflower.

4. Assemble. Transfer the mixture to a baking dish and sprinkle with more cheese. Layer the top with crushed pork rinds, if using.
5. Bake. Place the baking dish in the oven, until cheese is melted and golden, and the casserole is bubbly. If desired, garnish with chives or parsley.

Is Chicken Cordon Bleu Casserole Keto?

It will depend on the recipe, but this casserole is keto! While many casserole recipes are made with potatoes or pasta as a base, we’re using roasted cauliflower instead — both healthy and delicious.
