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 the browned chicken to the pot. Add salt, pepper, dried thyme, dried parsley, and bay leaf. Stir well to coat everything evenly.
04 - Pour in the chicken broth and water. Bring to a gentle boil over medium-high heat.
05 - Add egg noodles and stir to submerge. 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 - Stir in frozen peas and heavy cream if using. Simmer uncovered for 3–5 minutes until peas are tender and the broth slightly thickens. Remove bay leaf, check seasoning, and adjust as needed. Serve hot, garnished with fresh parsley if desired.
