Chicken Cordon Bleu Lasagna

The rain was hammering against the kitchen window the afternoon my sister walked in carrying a grocery bag and a wild idea: what if Cordon Bleu and lasagna had a baby. I laughed at her, then spent the next hour building something neither of us expected to love this much. The smell that filled the house was absurd, layers of ham and chicken and melted Swiss bubbling under a golden crust. We ate standing up at the counter because nobody wanted to wait long enough to set the table.

I made this for a potluck once and watched three people skip the dessert table just to go back for seconds. There is something about the combination of Swiss cheese and ham tucked between pasta layers that makes people close their eyes when they take the first bite. My brother in law now requests it every single holiday, and I have stopped arguing.

Ingredients

• Cooked chicken breast (3 cups shredded or diced): Rotisserie chicken works brilliantly here and saves you a step when you are short on time.
• Deli ham (8 oz thinly sliced): A good quality smoked ham from the deli counter makes a noticeable difference over prepackaged.
• Swiss cheese (2 cups shredded): Shred it yourself for better melting and a more even layer throughout the lasagna.
• Mozzarella cheese (1 cup shredded): This adds that stretchy golden top we all fight over.
• Parmesan cheese (1/2 cup grated): A sprinkle on top creates a salty crunchy finish.
• Lasagna noodles (12 regular or no boil): No boil noodles are a lifesaver but regular ones give a slightly sturdier bite.
• Unsalted butter (3 tbsp): The foundation of your bechamel so use real butter here.
• All purpose flour (3 tbsp): Creates the roux that thickens the sauce to silky perfection.
• Whole milk (3 cups): Whole milk gives the richest texture but two percent will work in a pinch.
• Dijon mustard (2 tsp): This is the secret ingredient that makes people ask what is in this sauce.
• Garlic powder (1/2 tsp), onion powder (1/2 tsp), salt (1/2 tsp), black pepper (1/4 tsp): Simple seasonings that quietly support everything else.
• Fresh parsley (2 tbsp chopped optional): A bright finish that cuts through the richness on the plate.

Instructions

Get the oven ready:

Preheat to 375 degrees and grease your 9 by 13 baking dish so nothing sticks later.

Prepare the noodles:

If using regular noodles cook them al dente according to the package then drain and lay them flat so they do not clump together.

Build the bechamel:

Melt butter in a saucepan over medium heat then whisk in the flour and cook for one to two minutes until it smells lightly toasty.

Make it silky:

Gradually pour in the milk whisking constantly and keep stirring until the sauce thickens which takes 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.

Start layering:

Spread a thin layer of sauce on the bottom of the dish then add noodles half the chicken half the ham and a third of the Swiss cheese followed by more sauce.

Build again:

Repeat with another round of noodles chicken ham Swiss and sauce pressing gently so the layers settle together.

Finish the top:

Crown it with a final layer of noodles the remaining sauce and all the mozzarella and Parmesan spread evenly.

Bake covered:

Cover tightly with foil and bake for 30 minutes so everything melts and merges underneath.

Uncover and brown:

Remove the foil and bake another 15 to 20 minutes until the top is deeply golden and bubbling at the edges.

Rest and serve:

Let it sit for 10 minutes before slicing so the layers hold together and garnish with parsley if you like.

Pin It

One winter evening I brought this to a neighbors house after her new baby came home and she texted me three days later asking for the recipe. Food does that sometimes, carrying warmth into a moment when someone needs it most.

What to Serve Alongside

A crisp green salad with a vinaigrette cuts through the richness and gives your plate some welcome contrast. A glass of Chardonnay alongside feels right, something with enough acidity to stand up to all that cheese.

Making It Your Own

Smoked turkey works beautifully in place of chicken if you want a slightly different flavor profile. I once used leftover Thanksgiving turkey and it was one of the best accidental decisions I have ever made in this kitchen.

Storage and Reheating

Cover leftovers tightly and refrigerate for up to three days. The flavors deepen overnight which makes the second day almost better than the first.

• Reheat individual portions in the microwave at medium power so the cheese does not get rubbery.
• You can freeze portions wrapped tightly in foil for up to two months.
• Always let frozen portions thaw overnight in the fridge before reheating.

This lasagna is proof that sometimes the best dishes come from simply asking what if. Share it generously and watch it disappear.

Refrigerate in an airtight container for up to 4 days. Reheat covered at 350°F until heated through, about 20 minutes.

→ Can I freeze this?
