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