01 - Heat the olive oil in a large Dutch oven or heavy pot over medium heat.
02 - Add the chicken pieces and season lightly with salt and pepper. Sauté for 3 to 4 minutes until lightly browned but not cooked through. Remove chicken to a plate and set aside.
03 - In the same pot, add the onion, carrots, and celery. Sauté for 4 to 5 minutes until softened. Add the garlic and cook for 1 minute until fragrant.
04 - Return the chicken to the pot. Stir in the thyme, oregano, bay leaf, and chicken broth. Bring to a gentle boil.
05 - Add the noodles, reduce heat to a simmer, and cook uncovered for 10 to 12 minutes, stirring occasionally, until the noodles are tender and the chicken is cooked through.
06 - For a creamy version, stir in the heavy cream. Heat through but do not boil.
07 - Remove the bay leaf, taste, and adjust seasoning with salt and pepper as needed. Serve hot, garnished with fresh parsley.
