Chicken Cordon Bleu Casserole

The first time I tried to make classic Chicken Cordon Bleu, I remember standing in my kitchen, flustered, trying to keep the rolled chicken from unraveling while simultaneously breading and frying each piece. It was delicious, yes—but exhausting. That’s why when I discovered a simpler version in casserole form, it was a game-changer. This Chicken Cordon Bleu Casserole is everything you love about the original—savory ham, creamy cheese, tender chicken—without the fuss.

Perfect for beginner cooks, this Chicken Cordon Bleu Casserole recipe is a dream come true. It’s an easy sheet pan dinner alternative that transforms traditional flavors into a comforting, quick and healthy meal. With its simple layering technique and rich flavor, this casserole is an ideal go-to for busy weeknights or when you’re just learning to navigate the kitchen.

Why This Recipe is Special

Classic Chicken Cordon Bleu involves pounding chicken, rolling in cheese and ham, breading, and frying—techniques that can feel intimidating to many. This casserole version cuts through all of that. There’s no rolling, no frying, and definitely no stress.

Instead, you get all the layered, indulgent flavors in one easy-to-assemble dish. The dijon-cream cheese sauce brings tang and creaminess, while the ham and Swiss provide classic depth. It’s naturally low-carb, gluten-free, and a great way to use leftover chicken or deli meat in a fresh, comforting way.

Ingredients and Preparation

Cooked Chicken
Provides the protein base. Use rotisserie chicken for convenience, or roast and shred your own. Juicy chicken ensures the casserole stays moist and satisfying.

Ham
Adds a salty, savory contrast to the chicken. Diced cooked ham or even deli slices work perfectly. Smoked ham adds extra depth.

Swiss Cheese
Melts beautifully with a mild, nutty flavor that complements the dijon sauce. Provolone, Havarti, or mozzarella can be used if you’re not a fan of Swiss.

Butter
Forms the rich base of the sauce. It brings flavor and silkiness.

Cream Cheese
Gives the sauce a creamy, luscious texture. Also helps thicken the mixture without needing flour.

Dijon Mustard
Adds tang and sharpness, cutting through the richness of the dairy. Regular mustard works in a pinch, though dijon is ideal.

Lemon Juice
Brightens the sauce and balances the fat. Lime juice can substitute in a pinch, though the flavor will be different.

White Wine (Optional)
Adds sophistication and complexity. Not essential, but a splash of broth or apple juice can be used as a substitute.

Salt
Essential for enhancing every other flavor.

Step-by-Step Instructions

Step 1
Preheat your oven to 350°F (175°C). In a 9×13 baking dish, spread an even layer of shredded cooked chicken across the bottom.

Step 2
Scatter the chopped ham over the chicken. Try to distribute it evenly so every bite has a bit of both meats.

Step 3
In a mixing bowl, blend the melted butter, softened cream cheese, dijon mustard, lemon juice, white wine (if using), and salt until smooth. A hand mixer makes this easier, but a sturdy whisk works fine too.

Step 4
Pour the sauce mixture over the chicken and ham, using a spatula to spread it into all corners and crevices of the dish.

Step 5
Layer slices or shreds of Swiss cheese on top of the sauce. This will melt into a gooey, golden topping during baking.

Step 6
Bake uncovered for 30 to 40 minutes until the top is bubbling and slightly golden. For a more browned top, broil for 2 minutes at the end—but keep a close eye on it to avoid burning.

Beginner Tips and Notes

• Dry Chicken? If your cooked chicken feels dry, add ¼ cup of chicken broth to the sauce or mix some of the sauce into the chicken before layering.
• Cheese Substitutions: Provolone, mozzarella, or even sharp cheddar can be used if Swiss isn’t your favorite.
• No Mixer? Soften the cream cheese thoroughly and mix the sauce by hand with a whisk or fork.
• Sauce Too Thick? Thin it with a tablespoon or two of broth or milk until spreadable.
• Prepping Efficiently: Use pre-cooked rotisserie chicken and pre-sliced ham to cut prep time dramatically.

Serving Suggestions

Pair this casserole with light, fresh sides to balance the richness. A crisp green salad with lemon vinaigrette, steamed green beans, or roasted asparagus are excellent choices. For a heartier option, serve alongside mashed cauliflower or buttery peas.

Storage Tips: Leftovers can be stored in an airtight container in the fridge for up to 4 days. Reheat in the oven at 325°F or in the microwave in short bursts to prevent the cheese from overcooking.
