Creating Chicken Cordon Bleu Soup is simple when you follow these easy steps:

1. Sauté Chicken and Ham: In a large pot, heat olive oil over medium heat. Add the diced chicken and ham, cooking until the chicken is no longer pink. This should take about 5–7 minutes.

2. Add Aromatics: Stir in the diced onion and minced garlic, cooking until the onion becomes translucent, approximately 3–4 minutes.

3. Sprinkle Flour: Sprinkle the flour over the chicken mixture, stirring constantly for about 1 minute to create a roux.

4. Add Broth: Gradually pour in the chicken broth, stirring well to combine and break up any lumps from the flour.

5. Season the Soup: Add in the dried thyme, salt, and black pepper. Then, bring the mixture to a gentle simmer.

6. Incorporate Cream and Cheese: Slowly stir in the heavy cream and shredded Swiss cheese, allowing the cheese to melt and the soup to become creamy.

7. Add Spinach: If using spinach, stir it in at this point, allowing it to wilt in the warm soup.

8. Stir in Dijon Mustard: Mix in the Dijon mustard for added flavor, adjusting seasoning to taste.

9. Simmer: Allow the soup to simmer for 5–10 minutes, ensuring everything is heated through while stirring occasionally.

10. Serve: Ladle the soup into bowls and garnish with fresh parsley if desired.

These steps will help you create a bowl of Chicken Cordon Bleu Soup that is as delightful as it is comforting.
