Chicken Cordon Bleu Lasagna

The idea hit me on a Tuesday evening while staring at leftover chicken and a package of deli ham that needed using. I had been craving lasagna but also something with that salty, cheesy punch of cordon bleu, and somehow my brain merged the two into what has since become the most requested dinner at every potluck I attend. The first attempt was messy, but the flavor was so outrageously good that nobody cared about the ragged edges. That dish disappeared in fifteen minutes flat, and my friend David literally licked his plate.

I made this for my mother in law the second time, fully expecting her polite nod and that measured smile she reserves for dishes she finds interesting but not quite right. She went back for a second helping before anyone else at the table had finished their first, and then she asked for the recipe, which in her vocabulary is the highest compliment a cook can receive.

Ingredients

• 3 cups cooked chicken breast, shredded or diced: Rotisserie chicken is your best friend here since the flavor gets amplified by everything around it.
• 8 oz deli ham, thinly sliced: Go for a good quality black forest or honey ham from the deli counter, not the presorted packets.
• 2 cups shredded Swiss cheese: Swiss melts beautifully and brings that classic cordon bleu identity to every bite.
• 1 cup shredded mozzarella cheese: This adds the stretch factor that makes pulling apart a slice so satisfying.
• 1/2 cup grated Parmesan cheese: A salty, golden crust on top that you will keep picking at straight from the dish.
• 12 lasagna noodles: No boil noodles save time but regular ones cooked al dente hold up slightly better in layers.
• 3 tbsp unsalted butter: The foundation of your béchamel, so use real butter and nothing else.
• 3 tbsp all purpose flour: This is what turns milk into a velvety sauce instead of soup.
• 3 cups whole milk: Whole milk is non negotiable for the richness this dish demands.
• 2 tsp Dijon mustard: This small amount quietly transforms the entire sauce into something extraordinary.
• 1/2 tsp garlic powder: Just enough background warmth without overpowering the delicate Swiss flavor.
• 1/2 tsp onion powder: Works hand in hand with the garlic to build subtle depth.
• 1/4 tsp black pepper: A gentle heat that balances all the richness.
• 1/2 tsp salt: Adjust after tasting since ham and Parmesan already contribute saltiness.
• 2 tbsp fresh parsley, chopped (optional): A bright finish that makes the whole dish look as good as it smells.

Instructions

Preheat and prepare:

Set your oven to 375 degrees Fahrenheit and grease a 9 by 13 inch baking dish with butter so nothing sticks later.

Cook the noodles:

If using regular noodles, boil them just until al dente and lay them flat on a clean towel so they do not tear or clump together.

Start the béchamel:

Melt the butter in a medium saucepan over medium heat, then whisk in the flour and let it cook for about a minute until it smells faintly toasted.

Build the sauce:

Pour in the milk gradually while whisking constantly to prevent lumps, and keep stirring until the sauce thickens enough to coat the back of a spoon.

Season the sauce:

Stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper, then remove from heat and taste it because this is where the magic happens.

Begin layering:

Spread a thin layer of sauce on the bottom of the dish, then lay down noodles followed by half the chicken, half the ham, and a third of the Swiss cheese, then spoon more sauce over everything.

Build the second layer:

Repeat with more noodles, the remaining chicken, the remaining ham, another third of Swiss, and more sauce draped generously across the top.

Finish the top:

Add a final layer of noodles, pour over every last bit of remaining sauce, and scatter the mozzarella and Parmesan across the entire surface.

Bake covered:

Cover tightly with aluminum foil and bake for 30 minutes so the cheese melts and the layers settle into each other.

Brown the top:

Remove the foil and bake another 15 to 20 minutes until the cheese is golden and bubbling in a way that makes your kitchen smell incredible.

Rest and serve:

Let it sit for 10 minutes before slicing so the layers hold together, then scatter parsley on top if you are feeling fancy.

There is something about pulling this golden, bubbling dish from the oven that makes everyone drift into the kitchen like moths to a flame, hovering with plates before you even say dinner is ready.

Making It Your Own

Swap the Swiss for Gruyère if you want a deeper, nuttier flavor that elevates the whole dish into something bordering on elegant. Smoked turkey works surprisingly well in place of chicken, giving the layers a campfire warmth that feels right during autumn. The beauty of this recipe is how forgiving it is with substitutions as long as you keep the béchamel and the layered structure intact.

What To Serve Alongside

A crisp green salad with a sharp vinaigrette cuts through the richness perfectly and gives your palate something fresh between bites. A glass of unoaked Chardonnay pairs beautifully with the Swiss and ham, or serve sparkling water with lemon for something lighter. Steamed asparagus or roasted green beans also make excellent companions that round out the plate without competing for attention.

Storage and Reheating

This lasagna actually tastes better the next day once the layers have had time to fully settle and the flavors marry overnight in the fridge. Cover the dish tightly and it will keep for up to four days, reheating beautifully in the oven at 350 degrees until warmed through. You can also freeze individual portions wrapped tightly in foil for those nights when cooking feels impossible.

• Let frozen portions thaw overnight in the fridge before reheating for the best texture.
• A splash of milk on top before reheating prevents the edges from drying out.
• Never microwave on full power or the cheese will turn rubbery and sad.

Save

Every time I make this dish, someone asks for the recipe, and I always smile because the real secret is just combining two classics that were always meant to find each other. Share it generously and watch it disappear.

Recipe FAQs

→ Can I make this ahead of time?

Absolutely. Assemble the entire dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time if baking cold from the refrigerator.

→ What can I substitute for Swiss cheese?

Gruyère offers a richer, nuttier flavor profile if you want to elevate the dish. Provolone or Emmental also work beautifully and melt just as well as Swiss.

→ Can I use no-boil noodles?

Yes, no-boil noodles work perfectly here. The creamy béchamel provides enough moisture for them to cook properly in the oven. No need to adjust the liquid or baking time.

→ How should I store leftovers?

Cover individual portions or the entire dish and refrigerate for 3-4 days. The flavors often improve overnight. Reheat covered with foil at 350°F until warmed through.

→ Can I freeze this dish?

You can freeze it either before or after baking. Wrap tightly in plastic and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before baking or reheating.

→ What sides work well with this?

A crisp green salad with vinaigrette cuts through the richness beautifully. Roasted vegetables like asparagus or green beans also complement the creamy, cheesy layers nicely.
