Creating this amazing soup is simple if you follow these straightforward steps:

1. Prepare the Ingredients: Start by shredding the rotisserie chicken into bite-sized pieces. Slice the mushrooms, dice the onion, and mince the garlic.
2. Sauté Vegetables: In a large pot, heat the olive oil over medium heat. Add the diced onion and sauté until it becomes translucent, about 3-4 minutes. Then, add the minced garlic and sliced mushrooms, cooking until the mushrooms are tender.
3. Combine Chicken and Broth: Stir in the shredded rotisserie chicken, followed by the chicken broth. Bring the mixture to a gentle boil.
4. Add Seasonings: Add the dried thyme and rosemary to the pot. Season with salt and pepper to taste. Let it simmer for 10 minutes to infuse the flavors.
5. Mix in Cream: Reduce the heat to low and stir in the heavy cream. Allow the soup to simmer for an additional 10 minutes, stirring occasionally.
6. Add Spinach (Optional): If using fresh spinach, stir it into the soup and let it wilt for about 2 minutes.
7. Serve: Remove from heat and garnish with freshly chopped parsley for added freshness.
