"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

Make Ahead Casserole

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

Tools
- 12" cast iron skillet or similar sized baking dish
- Measuring spoons
- Mixing bowl
- Whisk
- Mixing Spoon
Ingredients
1 tbsp olive oil
1/2 cup onion, diced (up to 1 cup onion)
4 cups baby spinach
1 medium zucchini, cut into 1/2" pieces (approx. 2 cups)
4 cups chopped pre-cooked chicken (we used 22 oz frozen roasted diced chicken, thawed)
2 cups cooked ham, diced (we used 1/2 a ham steak)
4 oz cream cheese, softened
3/4 cup sour cream
1 tablespoon dijon
1 teaspoon lemon juice
1 teaspoon herbs de provence, dried
1 1/2 cups swiss cheese, shredded (reserve 1/2 cup for the top)
1/4 tsp salt and pepper each to taste
How To Make Healthy Cordon Bleu Casserole
Preheat oven to 375 degrees F.
In an oven-proof skillet, saute onions and zucchini in olive oil until soft. Add spinach and toss until wilted.
Reduce heat to low. Add diced cooked chicken and ham and toss until warm. Turn off heat.
In a small bowl mix sour cream, cream cheese, dijon, lemon juice, thyme, salt, and pepper until blended. Pour over the top of the casserole and mix.
Add 1 cup of the shredded swiss cheese and stir into casserole. Do a quick taste test and add salt and pepper if needed.
Top casserole with remaining 1/2 cup cheese. Finally, bake the casserole 18 to 20 minutes until the casserole is bubbly and cheese is melted.
Helpful Hints
- 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!

Why does it say "In a small bowl mix cream......" when cream isn't listed as an ingredient??? Help, cooking as we speak!!
seekinggoodeats says
no cream that's a typo! I apologize...it is corrected now. I am so sorry - I even re-read multiple times! 🙂
seekinggoodeats says
The ingredient list is correct, the "cream" was a typo in the instructions. No cream needed. Both the instructions and recipe card match now. Thanks for you patience. Hopefully all turned out well - this is a favorite recipe of mine 'cause I LOVE cordon bleu! LOL 🙂
Hali Harden says
Do you think this is saucy enough to serve over zoodles?
Kori says
It's not pasta "saucy", but I actually just made this again last night and served it over riced cauliflower. It's not super saucy but it is nice to have the freshness of vegetables along with the casserole. You could still make zoodles but maybe toss them with a little olive oil or butter then season with salt and pepper. YOu could serve the casserole on top or on the side. 🙂
