The Origin and Appeal of Chicken Cordon Bleu Casserole

What is Chicken Cordon Bleu?

Originally rooted in Swiss culinary tradition, the term “cordon bleu” refers to a dish where meat—typically veal or chicken—is wrapped around cheese and sometimes ham, then breaded and pan-fried or baked. Over time, the chicken version became a popular favorite in the U.S., typically featuring chicken breast stuffed with ham and Swiss cheese. The New York Times first mentioned “chicken cordon bleu” in 1967, though similar veal recipes date back to the 1950s. While delicious, traditional cordon bleu can be time-consuming and tricky for everyday cooks.

Why Turn it into a Casserole?

Let’s be honest—weeknight dinners need to be fast, easy, and crowd-pleasing. That’s where Chicken Cordon Bleu Casserole steps in. By skipping the breading and rolling, and instead layering everything into a baking dish, this recipe simplifies the process while keeping the core flavors intact. The result? All the indulgence, none of the hassle. It’s the perfect choice for busy families or anyone on a keto or low-carb diet who still craves something creamy and satisfying.

Who Loves This Dish?

Whether you’re a fan of classic comfort food or sticking to a gluten-free lifestyle, Chicken Cordon Bleu Casserole fits the bill. It’s a hit with picky eaters (yes, even with Swiss cheese involved), loved by keto and low-carb dieters, and impressively versatile. From weeknight family meals to holiday potlucks, it earns rave reviews. And for those watching their macros, this one keeps carbs low without sacrificing taste.

Key Ingredients for the Perfect Chicken Cordon Bleu Casserole

Shredded Chicken vs. Tenderloins

You can use either shredded cooked chicken or whole baked tenderloins as your base. Shredded chicken absorbs the sauce better, especially when mixed with broth or additional cream for moisture. Tenderloins save you a prep step—just bake, drain any excess liquid, and layer into your casserole. Pro tip: moist chicken equals flavorful casserole. If your chicken is on the drier side, consider making 1.5x the sauce.

Ham and Cheese: What Works Best?

Classic Chicken Cordon Bleu calls for thinly sliced ham and Swiss cheese. For the casserole version, diced ham chunks work beautifully—they’re hearty and infuse flavor into every bite. As for cheese, Swiss remains the go-to for authenticity, but provolone, mozzarella, or Havarti can be swapped in for milder or creamier profiles, especially if serving kids.

The Creamy Dijon Sauce Breakdown

This sauce is where the casserole truly shines. It starts with melted butter and softened cream cheese, blended with Dijon mustard and lemon juice for brightness. A splash of white wine (optional) adds depth, and a dash of salt ties it all together. Want a thinner consistency? Add chicken broth. Prefer richer? Toss in a bit of heavy cream.

Step-by-Step: How to Make Chicken Cordon Bleu Casserole

Prep the Ingredients

Begin with about 6 cups of shredded cooked chicken (roughly 2 pounds). Dice 6 oz of ham into bite-sized pieces. If needed, soften 6 oz of cream cheese in the microwave for easy mixing. Preheat your oven to 350°F.

Layer and Assemble

In a 9×13-inch baking dish, layer the shredded chicken evenly, then sprinkle the diced ham over it. Next, blend your sauce: use an electric mixer to combine melted butter, cream cheese, Dijon mustard, lemon juice, optional wine, and salt until smooth. Spread this creamy mix over the chicken and ham base.

Bake to Perfection

Top it all with about 5 oz of Swiss cheese slices. Bake uncovered for 30–40 minutes until the casserole is bubbly and golden. Want that signature cheesy crust? Broil for an additional 2 minutes—but don’t walk away, it browns fast!

Serving and Pairing Chicken Cordon Bleu Casserole

What to Serve Alongside

Because this casserole is rich and cheesy, it pairs best with lighter, fresh sides. Think green salads with vinaigrette, steamed broccoli, roasted asparagus, or cauliflower mash. These sides cut through the richness and balance out the meal. Want to keep it keto? A crisp cucumber-avocado salad works wonders.

Family Dinner to Fancy Brunch

One of the greatest perks of this casserole is its flexibility. You can serve it straight from the oven on a busy Tuesday night or plate it in ramekins for a more elegant brunch offering. Top with fresh herbs, add a lemon wedge on the side, and suddenly you’ve got a dish worthy of a Sunday table spread.

Leftovers and Meal Prep Tips

This casserole keeps wonderfully in the fridge for up to four days. Store it in airtight containers for grab-and-go lunches or quick weeknight dinners. For freezing, cool completely first, then wrap tightly in foil or transfer to freezer-safe containers. Reheat in the oven at 350°F for best results.

Variations and Creative Twists on the Classic

Add-Ins to Elevate the Flavor

Want to bulk it up or sneak in veggies? Broccoli florets, sautéed mushrooms, or even spinach make excellent add-ins. Stir them into the sauce before spreading or layer them under the cheese. Craving crunch? Top your casserole with crushed pork rinds or almond flour mixed with butter for a keto “breadcrumb” topping.

Dairy-Free or Gluten-Free Tweaks

To keep it dairy-free, use vegan cheese and substitute cream cheese with a plant-based alternative like cashew cream. Coconut cream can replace heavy cream or butter in the sauce. This dish is naturally gluten-free, making it ideal for grain-free lifestyles.

International Fusion Ideas

Put a spin on your casserole by mixing in bold international flavors. Use smoked gouda and spicy brown mustard for a smoky variation. Or try an Italian flair by adding oregano, swapping Dijon for basil pesto, and using mozzarella cheese. For a Mediterranean take, go with feta, kalamata olives, and a garlic-olive oil sauce.
