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 seared chicken to the pot. Add salt, pepper, dried thyme, dried parsley, and bay leaf. Stir well to evenly coat everything.
04 - Pour in chicken broth and water. Bring the mixture to a gentle boil over medium 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. Taste and adjust seasoning as needed.
07 - Remove and discard the bay leaf. Ladle into bowls and serve hot, garnished with fresh parsley if desired.
