Heat the olive oil in a large pot or Dutch oven over medium heat.
Add the diced onion and sauté for about 3-4 minutes until softened.
Stir in the minced garlic, sliced carrots, and celery. Cook for an additional 5 minutes, stirring occasionally.
Pour in the turkey or chicken broth and bring to a boil.
Once boiling, add the shredded turkey, dried thyme, dried parsley, and bay leaf.
Reduce the heat to a simmer and cook for 15 minutes.
Add the egg noodles and cook according to package instructions, usually around 8-10 minutes, until the noodles are tender.
Season with salt, pepper, and lemon juice (if using) to taste, and remove the bay leaf before serving.
Ladle the soup into bowls and garnish with fresh chopped parsley.
