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