Sauté vegetables: Add butter, diced onion, carrots, and celery to a large stock pot or Dutch oven. Sauté for 5 minutes over medium-high heat.
Add chicken broth: Pour the broth into the pot. Season with salt, pepper, bay leaves, thyme, and Better-Than-Bouillon. Stir to combine.
Bring to a boil: Cover and bring the broth to a rolling boil.
Add noodles: Add noodles and cook just until al dente. Remove from heat to prevent overcooking.
Stir in chicken: Add shredded rotisserie chicken. Taste and adjust seasonings as needed.
Serve: Ladle the soup into bowls, garnish with herbs, and serve hot with bread or rolls.
Store: Refrigerate leftovers in an airtight container for 4 to 5 days.
