Ingredients Needed
This chicken cordon bleu casserole recipe uses many kitchen staples for a mouth-watering, amazing dinner! It’s a great recipe for using up leftover shredded chicken and ham, if you have it. You can find exact measurements for each ingredient in the recipe card below.
- Chicken Breast: Rotisserie chicken is great because it is convenient and adds so much extra flavor.
- Ham: Deli ham is really handy but if you have leftover cooked ham, that works great too!
- Cheese: Swiss cheese is the traditional cheese variety used in cordon bleu recipes, but gouda or provolone would be delicious too. You want a creamy cheese that will get nice and melty.
- Butter: Mix with the breadcrumbs and seasoning to make the topping bake up golden brown.
- Breadcrumbs: We’re using panko bread crumbs for delicious crispiness.
- Seasoning: Italian seasoning and salt gives the bread crumb topping extra flavor.
Lemon Cream Sauce
- Butter: Unsalted butter makes the cream sauce flavorful and rich.
- Flour: To thicken the sauce for the chicken cordon bleu casserole.
- Broth: Use low sodium, good quality chicken broth for flavor and consistency in the lemon cream sauce.
- Milk and Cream: This combo makes the sauce incredibly creamy and smooth.
- Dijon Mustard: For a light tangy taste.
- Cheese: The sauce is finished with a blend of shredded parmesan cheese and shredded Swiss cheese.
- Lemon Juice: Adds wonderful fresh, lemony flavor.
- Salt & Pepper: To taste!
How to Make Cordon Bleu Casserole
There are several steps to follow when making this casserole, but they’re all very simple and straightforward. Once you make the topping and the sauce for the cordon bleu casserole, just assemble all of the layers in a pan and bake! Here’s how it all comes together:
- Prep: Preheat the oven to 350 degrees Fahrenheit and spray a 3-quart baking dish with pan spray.
- Add the Meat: Spread the shredded chicken in the bottom of the pan. Sprinkle the ham evenly over the chicken.
- Make the Topping: In a small bowl, stir together the melted butter, panko, Italian seasoning, and salt. Set aside.
- Making the Sauce: Prepare the lemon cream sauce by melting the butter in a medium saucepan over medium heat. Once melted, add the flour and whisk to combine. Continue to whisk until the mixture becomes nutty and fragrant and the bubbling subsides, about 2 minutes.
- Finish the Sauce: Slowly whisk in the broth, milk, cream, and dijon. Whisk until smooth and thickened, which should only take a minute or two. Whisk in the cheese slowly, whisking until it is fully melted. Whisk in the lemon juice and salt and pepper to taste.
- Assemble and Bake: Pour the sauce evenly over the chicken and ham and top with the shredded Swiss cheese. Top with the panko mixture and bake for 30-35 minutes, until the casserole is bubbling and the bread crumbs are golden brown. Top cordon bleu casserole with chopped parsley and hollandaise, if desired.
Tips and Variations
Here are some helpful tips and ways to make this dish your own! This Chicken Cordon Bleu Casserole is so tasty, I know your family is going to go crazy for it just like mine does!
- Different Chicken: Rotisserie chicken is called for in the recipe card, but you can use any cooked, boneless chicken. This could be leftover chicken from another recipe, frozen cooked chicken, canned, or some you have cooked up and cut up or shredded just for this recipe! Make it easy and use what you have on hand.
- Type of Ham: While cubed ham adds great texture, any ham will do. Use deli ham that has been chopped up, diced ham, leftover baked ham…just be sure whatever ham you use is cut into bite-sized pieces.
- Broil: Don’t be alarmed if the panko isn’t browning very deeply! You can brown it by turning the oven to broil for a minute or two, but keep a close eye on it so it doesn’t burn.
Storing Leftovers
- Make Ahead: Cordon bleu casserole is a great prepare-ahead meal! You can make the sauce up to 3 days in advance and store it in the refrigerator in an airtight container until you’re ready to assemble your casserole. You may also assemble the whole casserole the day before, cover it, and store it in the refrigerator. Allow 10-15 extra minutes of baking time, since all the ingredients will be chilled.
- Leftovers in the Refrigerator: Store leftovers in an airtight storage container in the fridge for up to 4 days.
- In the Freezer: To freeze, transfer leftovers to an airtight freezer-safe storage container and freeze for up to 3 months. Let thaw overnight in the refrigerator before reheating.
- To Reheat: Heat leftover cordon bleu casserole in the oven at 350 degrees Fahrenheit for 10-15 minutes, until the casserole has reached 165 degrees Fahrenheit. You can also reheat individual servings in the microwave.
