In a large pot or Dutch oven, heat olive oil over medium-high heat until shimmering. Add onion, carrots, and celery and cook until softened, about 5 minutes.
Stir in broth, turkey, thyme, and bay leaf. Bring to simmer and cook until vegetables are tender, about 15 minutes.
Stir in noodles and cook until tender, about 5 minutes longer. Remove from heat, season to taste with salt and pepper, and garnish with fresh parsley.
Broth: You can use either chicken broth or turkey broth in this recipe.
Leftovers: Cool completely, then store in the fridge and eat within 4 days.
Freezer: Freeze for up to 3 months to have on hand for soup emergencies.
Slow cooker: This takes a lot longer than the stove-top, but I don't mind if you don't. Add the broth, turkey, carrots, celery, onion, bay leaves, and thyme to the slow cooker. Cover, and cook on HIGH for 3 hours, or LOW for 6 hours. Stir in the egg noodles and cook 15 minutes longer on HIGH until the egg noodles are tender.
