Chicken Cordon Bleu Casserole

Introduction

Why does the classic Chicken Cordon Bleu taste amazing in restaurants, but feel complicated to make at home?

Between stuffing, breading, and frying, it can be time-consuming and messy.

That’s why this Chicken Cordon Bleu Casserole is such a game changer. It takes all the same flavors—juicy chicken, smoky ham, and melted Swiss cheese—and turns them into an easy baked dish. No breading, no frying, just simple layering and baking.

It’s creamy, cheesy, and perfect for busy weeknights or family dinners.

Ingredients

Main Layer:

2–3 cups cooked chicken (shredded or diced)
200g sliced ham (chopped)
1 1/2 cups Swiss cheese (or mozzarella)
1 small onion (optional, finely chopped)

Cream Sauce:

1 can cream of chicken soup (or homemade white sauce)
1/2 cup milk
1/2 cup sour cream or Greek yogurt
1 tsp garlic powder
1/2 tsp black pepper
1/2 tsp salt
1 tsp Dijon mustard (optional but recommended)

Topping:

1 cup breadcrumbs
2 tbsp melted butter
1/2 cup extra Swiss cheese (optional)

Substitutions:

Chicken → turkey or rotisserie chicken
Swiss cheese → mozzarella, provolone, or cheddar
Ham → turkey slices or smoked chicken
Sour cream → Greek yogurt

Timing

Preparation time: 15 minutes
Baking time: 30–35 minutes
Total time: about 50 minutes

Much faster than traditional Chicken Cordon Bleu, which requires breading and frying each piece.

Instructions

Step 1: Preheat oven

Preheat oven to 180°C (350°F). Grease a baking dish.

Step 2: Layer chicken and ham

Spread cooked chicken evenly in the dish. Add chopped ham on top. Sprinkle half of the Swiss cheese.

Tip: Even layering ensures every bite has balanced flavor.

Step 3: Make the sauce

Mix cream of chicken soup, milk, sour cream, garlic powder, salt, pepper, and Dijon mustard until smooth.

Tip: Dijon mustard adds a subtle tang that mimics classic cordon bleu flavor.

Step 4: Pour sauce

Pour sauce evenly over chicken and ham layers.

Step 5: Add topping

Mix breadcrumbs with melted butter and sprinkle over casserole. Add remaining cheese if desired.

Step 6: Bake

Bake uncovered for 30–35 minutes until golden and bubbly.

Step 7: Rest and serve

Let sit for 10 minutes before serving.

Tip: Resting helps the casserole set and makes slicing easier.
