01 - Heat olive oil over medium-high heat in a large Dutch oven or heavy-bottomed pot.
02 - Add chicken pieces and sauté until lightly browned on all sides, about 4–5 minutes. Remove and set aside.
03 - In the same pot, add onion, carrots, and celery; cook for 4 minutes until tender. Stir in garlic and cook for another minute.
04 - Return chicken to the pot. Add salt, pepper, thyme, parsley, and bay leaf. Stir well to coat evenly.
05 - Pour in chicken broth and water. Bring to a gentle boil.
06 - Add egg noodles, stir, and reduce heat to a simmer. Cover and cook for 10–12 minutes, stirring occasionally, until noodles are al dente and chicken is cooked through.
07 - Add frozen peas and heavy cream (if using). Simmer uncovered for another 3–5 minutes. Check seasoning and adjust as needed.
08 - Remove bay leaf. Serve hot, garnished with additional parsley if desired.
