The Best Recipe For Chicken Cordon Bleu Casserole!

"I have always LOVED chicken cordon bleu but it always seems to take a little longer than I want to spend on a meal and I still had to make a side dish to go with it. Problem solved! This casserole version makes it easy to get that same taste PLUS get your veggies in a full meal, one pan from stovetop to oven." -Kori

It's So Easy

I love that this is a one-pot casserole - from stovetop to oven it's super easy. With both protein and veggies, this is meal-in-one. This is the perfect recipe for using leftover chicken and ham - both ingredients can be purchased pre-cooked if you don't have leftovers.

Make-Ahead Casserole

Feel free to prep this casserole ahead of time. Follow the recipe instructions but don’t bake it. When you are ready for dinner pull it out of the refrigerator about 20 to 30 minutes before baking. You’ll need to increase the baking time slightly if the casserole is still chilled.

Alternatively, you can bake the casserole and store it in your refrigerator. Reheat the full casserole or individual portions until the casserole reaches 165 degrees.

Low Carb Keto

We made this chicken cordon bleu casserole just a little bit healthier by loading up on vegetables and not adding bread, pasta, or rice - resulting in only 3.9 grams of carbs. The healthy fats in this recipe come from the chicken and ham, the cheeses, and olive oil. There are 22.6 grams of fat in this recipe. For ways to lower the fat see our FAQ sections below.

How to Serve It

Easy Chicken Cordon Bleu Casserole Recipe | Seeking Good Eats (7)

This cordon bleu casserole recipe is really a meal in one, but here are some side dish ideas:

A fresh green salad. Try our layered salad! It's a make-ahead salad that is perfect for get-togethers, but you can also make it for dinner one night then eat leftovers for the next few lunches!

Roasted or steamed vegetables like broccoli, cauliflower, or green beans. Air fryer brussel sprouts are a quick an easy idea too!

With riced cauliflower or riced broccoli.

If you’ve got carb lovers in your house, this casserole is great with rolls or breadsticks.

Top Tips

  • Because of the variance of salt content amongst pre-cooked chicken and ham, you may not need to add salt or pepper. Do a taste test before you top the casserole with cheese. Adjust salt to your taste, starting with 1/4 teaspoon of salt and pepper. Add more if needed.
  • Always use freshly grated cheese! Pre-grated cheese in packages is coated with cellulose (a wood pulp) that absorbs moisture and prevents sticking of the cheese. Unfortunately, this also keeps the cheese from melting properly. Don’t you want the cheese to melt?
  • Feel free to substitute other vegetables. Keep the onions for flavor, but substitute squash, green beans, broccoli, or cauliflower if you have it. You can substitute kale for spinach, but it will need to cook a little longer to be tender.
  • You can use raw chicken thighs or chicken breast if you don't have pre-cooked chicken. Saute the chicken in the skillet with the onions until it is done. From there continue on with the recipe instructions by adding zucchini then spinach, and so on. So good!
