Creating Creamy Chicken Stew is easy when you follow these steps:

1. Sauté Chicken: In a large pot, heat olive oil over medium heat. Add the chicken thighs and cook until browned on all sides. Remove and set aside.
2. Cook Vegetables: In the same pot, add diced onion, carrots, and celery. Sauté for about 5-7 minutes until softened.
3. Add Garlic: Stir in minced garlic and cook for an additional minute until fragrant.
4. Make the Broth: Pour in the chicken broth, scraping the bottom of the pot to deglaze. Bring to a simmer.
5. Thicken the Stew: In a small bowl, whisk together heavy cream and flour until smooth. Slowly add to the pot, stirring constantly.
6. Return Chicken: Add the browned chicken thighs back to the pot. Stir in thyme, rosemary, salt, and pepper.
7. Simmer: Reduce heat to low and let the stew simmer for about 25-30 minutes, or until the chicken is cooked through and tender.
8. Adjust Seasoning: Taste the stew and adjust the seasoning if necessary.
9. Serve: Ladle the stew into bowls and garnish with fresh parsley.

These steps will guide you in creating a delicious creamy chicken stew that is sure to delight everyone at your table.
