Chicken Cordon Bleu Lasagna

The idea hit me on a Tuesday night while staring at leftover chicken and half a pack of deli ham in the fridge. I had been craving both Chicken Cordon Bleu and lasagna simultaneously, which my family found ridiculous until they tasted what came out of the oven. The kitchen smelled like a French bistro collided with an Italian grandmother, and nobody was complaining.

I served this at a potluck where three people independently asked for the recipe before they even finished their first plate. My sister in law called it dangerous because she went back for thirds without any shame.

Ingredients

• 3 cups cooked chicken breast, shredded or diced: Rotisserie chicken works beautifully here and saves you a step on busy weeknights.
• 8 oz deli ham, thinly sliced: Ask for it cut thin at the deli counter so it layers evenly between the pasta sheets.
• 2 cups shredded Swiss cheese: Swiss melts into a nutty, gooey layer that ties the chicken and ham together perfectly.
• 1 cup shredded mozzarella cheese: This goes on top for that irresistible stretchy golden finish.
• 1/2 cup grated Parmesan cheese: A little goes a long way for a salty, crispy top crust.
• 12 lasagna noodles: No boil noodles are a lifesaver, but regular ones work fine if cooked al dente first.
• 3 tbsp unsalted butter: The starting point for your béchamel, so use good quality butter.
• 3 tbsp all purpose flour: This thickens the sauce and gives it body without making it heavy.
• 3 cups whole milk: Whole milk makes the creamiest sauce, and you will notice the difference.
• 2 tsp Dijon mustard: This is the secret ingredient that elevates the whole dish from good to unforgettable.
• 1/2 tsp garlic powder: Adds subtle warmth without overpowering the delicate Swiss and ham flavors.
• 1/2 tsp onion powder: Works behind the scenes to round out the savory notes.
• 1/4 tsp black pepper: Just enough to give the sauce a gentle kick at the finish.
• 1/2 tsp salt: Taste your sauce before adding, because ham and Parmesan already bring saltiness.
• 2 tbsp fresh parsley, chopped: Optional, but the green sprinkle on top makes it look restaurant worthy.

Instructions

Preheat and prepare:

Set your oven to 375 degrees F and grease a 9 by 13 inch baking dish with butter or cooking spray so nothing sticks.

Cook the noodles:

If using regular noodles, boil them in salted water until just al dente, then drain and lay them flat so they do not 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 a minute or two 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 coats the back of a spoon, about five minutes.

Season the sauce:

Stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper, then pull it off the heat and give it a taste to adjust if needed.

Begin layering:

Spread a thin blanket of béchamel on the bottom of the dish, then lay down noodles, half the chicken, half the ham, and a third of the Swiss cheese before spooning on more sauce.

Repeat the layers:

Add another round of noodles, the remaining chicken and ham, more Swiss cheese, and more sauce, pressing gently so everything settles together.

Finish the top:

Cover everything with a final layer of noodles, the rest of the sauce, then scatter the mozzarella and Parmesan evenly across the top.

Bake covered:

Wrap the dish tightly in foil and slide it into the oven for 30 minutes so the flavors meld and the edges bubble.

Brown the top:

Peel off the foil and bake another 15 to 20 minutes until the cheese is golden and irresistible looking.

Rest and serve:

Let it sit for 10 minutes before cutting so the layers hold together, then scatter parsley over the top if you like.

One winter evening my nephew asked if we could have this for his birthday dinner instead of cake, and honestly I was flattered and a little concerned about his priorities.

Swapping Ingredients Like a Pro

Gruyere cheese makes a luxurious substitute for Swiss if you want something deeper and more complex. Smoked turkey can stand in for the chicken when you want a slightly different flavor profile without changing the spirit of the dish.

What to Serve Alongside

A crisp green salad with a bright vinaigrette cuts through the richness perfectly. A glass of Chardonnay sitting next to your plate turns a weeknight dinner into something that feels deliberate and special.

Making It Ahead

You can assemble the entire lasagna a day ahead, keep it covered in the fridge, and bake it when you are ready. Just add about ten extra minutes to the covered baking time if it goes in cold.

• Let it sit on the counter for 20 minutes before baking to take the chill off.
• Cover the top with extra cheese before baking to refresh the look.
• Leftovers reheat beautifully in the oven at 350 degrees for about 15 minutes.

Some dishes are just a meal, but this one has a way of pulling people back to the kitchen for seconds while they are still finishing their first plate. That is the highest compliment any recipe can receive.

Recipe FAQs

→ Can I assemble this ahead of time?

Yes, assemble the entire dish up to 24 hours in advance and refrigerate. Add 5-10 minutes to the covered baking time if baking from cold.

→ What cheese works best for this bake?

Swiss cheese provides traditional flavor, but Gruyère offers a richer, nuttier taste. The mozzarella creates the perfect bubbly top layer.

→ Can I use no-boil noodles?

Absolutely. No-boil noodles work beautifully here and save preparation time. They'll absorb moisture from the béchamel during baking.

→ How do I store leftovers?

Refrigerate in an airtight container for up to 4 days. Reheat individual portions in the microwave or covered in a 350°F oven.

→ Can I freeze this dish?

Freeze before baking for up to 3 months. Thaw overnight in the refrigerator, then bake as directed, adding extra time if needed.

→ What sides pair well?

A crisp green salad with vinaigrette balances the richness. Steamed green beans or roasted asparagus also complement the creamy layers.
