Keto Chicken Cordon Bleu Casserole: Easy, Creamy & Low Carb Food

Some days you just want something warm, creamy, and cheesy. And if you’re living that low carb eating life, it can feel like all the good stuff is off-limits. Breaded chicken? Gone. Creamy sauces? Maybe. But not today.

This keto chicken cordon bleu casserole tastes like it came from a fancy restaurant, but it’s the kind of dish that ends up on regular repeat in your kitchen. No rolling chicken, no deep frying, and definitely no carbs worth counting. Just comfort in a dish.

Let’s break it down, what you’ll need, how to make it, why it works, and what to serve it with. I’ll even share some personal notes that might help if you’re following something like Trim Healthy Mama or just need low carb casseroles that the whole family won’t moan about.

What Is Chicken Cordon Bleu Casserole?

Classic chicken cordon bleu is usually a breaded chicken breast stuffed with ham and Swiss cheese. It gets fried or baked and sometimes served with a creamy sauce.

This casserole version skips all the fuss. No pounding meat, no rolling or toothpicks. It layers all the good parts of cordon bleu in a baking dish—cooked chicken, chopped ham, Swiss cheese, a rich cream sauce, and a crunchy topping that’s still low carb. It’s basically what you’d get if your favorite restaurant dish crashed into a weeknight casserole.

Why This Casserole Works

• Fast to prep – Cook the meat ahead, and it’s just layering and baking.

• Leftovers win – It reheats like a dream. Maybe even better the next day.

• Family-approved – Your kids don’t have to know it’s low carb.

• Trim Healthy Mama-friendly – It’s an “S” meal if you’re following THM recipes.

• Freezer-ready – Make two. Eat one. Freeze one.

• Low carb dinner goals – It’s rich without going overboard on carbs.

Ingredients

Here’s what you’ll need. Keep it simple, or tweak to taste.

For the base:

• 3 cups cooked chicken, shredded or chopped (rotisserie chicken works great)

• 1.5 cups cooked ham, diced

• 6 slices Swiss cheese

For the sauce:

• 4 oz cream cheese, softened

• 1/2 cup heavy cream

• 1/2 cup chicken broth

• 1 tbsp Dijon mustard

• 1 tsp garlic powder

• Salt and pepper to taste

For the topping:

• 1/2 cup grated Parmesan

• 1/4 cup crushed pork rinds or almond flour (for crunch)

• 2 tbsp melted butter

How To Make It (Step-by-Step)

Step 1: Preheat and prep

Start by heating your oven to 375°F. Grease a 9×13 baking dish. Don’t skip greasing—even low carb casseroles like to stick if they’re full of cheese.

Step 2: Layer the meat

Spread your chopped chicken in the bottom of the dish. Sprinkle your diced ham evenly over that. Top with slices of Swiss cheese. You can cut or tear the slices to cover better.

Step 3: Make the sauce

In a small pot or skillet, mix cream cheese, heavy cream, and chicken broth over medium heat. Whisk till it’s smooth. Stir in mustard, garlic powder, salt, and pepper. Let it simmer a few minutes till it thickens slightly.

Step 4: Pour it on

Take that warm sauce and pour it over your meat and cheese layers. Use a spoon to spread it if needed so it covers everything nicely.

Step 5: Add the topping

Mix Parmesan, pork rinds (or almond flour), and melted butter in a small bowl. Sprinkle that across the top of the casserole. This gives that crispy bite that’s usually from breadcrumbs—without the carbs.

Step 6: Bake

Pop it in the oven for about 25–30 minutes. You want it bubbly and golden. Let it sit 5 minutes before serving.

What To Serve With this Keto Chicken Cordon Bleu Casserole

This keto chicken cordon bleu casserole is pretty rich, so something light works well next to it.

• Steamed green beans

• Roasted broccoli

• Side salad with ranch or oil and vinegar

• Cauliflower mash

If you’re doing a weekend brunch spread, and want something that balances this dish—keto pancakes are weirdly good next to this. Salty + sweet works, even on low carb.

How To Store It

• Fridge – Store leftovers in an airtight container. It’ll last about 4 days.

• Freezer – Freeze the whole dish before baking if you want to make ahead. Cover tight with foil and plastic wrap. Bake straight from frozen, but add 15–20 minutes extra bake time.

Personal Notes & Tips

When I first made this, I thought there’s no way this would beat regular chicken cordon bleu. I was wrong. My husband, who couldn’t care less about trim healthy or low carb eating, went back for thirds. Not seconds. Thirds.

I’ve made this casserole for potlucks, meal trains, and even a bridal shower brunch. It disappears every time. And nobody has ever guessed it’s one of those low carb casseroles that are supposed to be “healthy.”

Once I forgot the mustard and it still turned out great, so don’t stress if you’re missing a thing or two. Also—if you’re tracking carbs carefully, go easy on the ham. Some brands sneak sugar in there.

If you’re doing THM recipes, this casserole pairs nicely with a simple side salad with olive oil dressing. Keep it in the “S” meal zone.

How To Make It Your Own

This is where you get to play around.

• Use smoked turkey instead of ham

• Try provolone instead of Swiss

• Add spinach or cooked mushrooms between layers

• Make minis in muffin tins for lunchbox portions

The sauce is pretty forgiving too. Add some shredded cheddar for more sharpness. Or use sour cream instead of cream cheese if that’s what’s in the fridge.
