01 - Warm the olive oil in a large Dutch oven or heavy-bottomed pot over medium heat until shimmering.
02 - Add the chicken pieces in a single layer and season lightly with salt and pepper. Sauté for 3 to 4 minutes, turning once, until lightly browned on the outside but not fully cooked through. Transfer to a plate and set aside.
03 - In the same pot, add the onion, carrots, and celery. Cook for 4 to 5 minutes, stirring occasionally, until the vegetables have softened. Add the minced garlic and cook for 1 minute until fragrant.
04 - Return the seared chicken to the pot. Add the dried thyme, oregano, bay leaf, and chicken broth. Stir to combine and bring the mixture to a gentle boil.
05 - Stir in the noodles, then reduce the heat to a simmer. Cook uncovered for 10 to 12 minutes, stirring occasionally to prevent sticking, until the noodles are tender and the chicken is cooked through to an internal temperature of 165°F.
06 - For a richer texture, stir in the heavy cream. Heat through gently but do not allow the mixture to come to a boil.
07 - Remove and discard the bay leaf. Taste the broth and adjust the seasoning with additional salt and pepper as needed. Ladle into bowls and garnish generously with fresh chopped parsley. Serve hot.
