Heat olive oil in a 6-quart Dutch oven or heavy-bottomed stockpot over medium heat.
Add onion, carrots, and celery to the pot; sauté for 7 minutes until onions are translucent and carrots have slightly softened.
Add minced garlic and cook for 60 seconds until aromatic, ensuring no browning occurs.
Incorporate chicken stock, dried thyme, and the bay leaf; increase heat to high and bring the liquid to a rolling boil.
Reduce heat to medium-low to maintain a simmer; cook for 10 minutes to develop flavor profiles.
Increase heat slightly to return to a boil and add wide egg noodles; cook for 7 to 9 minutes or until noodles reach al dente texture.
Stir in shredded rotisserie chicken meat and heat for 3 minutes until the protein reaches an internal temperature of 165°F (74°C).
Discard the bay leaf, season with salt and pepper, and garnish with chopped parsley immediately before service.
