"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

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

Ingredients and Tools
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
Step by Step Instructions
Here are the instructions for making Healthy Chicken 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.
- 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!
