Chicken Cordon Bleu Casserole: Easy Irresistible Dish
Ingredients
Method
- Heat your oven to 350°F (175°C) and prepare a 9×13 inch baking dish by greasing it.
- In a large bowl, toss together the shredded chicken, diced ham, and 1 ½ cups of the Swiss cheese.
- In a smaller bowl, blend sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until smoothly combined.
- Pour this creamy mixture over the chicken and ham, stirring carefully until all ingredients are evenly coated.
- Transfer everything into the baking dish and spread it out evenly.
- Scatter the remaining ½ cup of Swiss cheese on top.
- If using, combine bread crumbs with melted butter and sprinkle this over the cheese layer.
- Bake in the oven for about 25 to 30 minutes, or until the casserole is hot throughout and the cheese has melted and is bubbly.
- Allow the casserole to rest for a few minutes before slicing and serving.
Notes
- Choose quality ham and Swiss cheese to boost flavor. Keep an eye on the bread crumb topping to prevent over-browning; cover with foil if needed. Let it cool slightly to improve the flavors. For a twist, switch Swiss cheese with Gruyere or add veggies like sautéed mushrooms, broccoli, or asparagus. You can also make the dish up to 24 hours ahead and refrigerate. Leftovers keep well for up to 3 days in the fridge.
