Creamy Turkey Dumpling Soup is the perfect way to use leftovers from Thanksgiving. It's hearty, full of vegetables, and easy to make. And the best part is the light and fluffy dumplings.
In a large stockpot melt the butter over medium heat. Add carrots, celery, potatoes, and onion. Cook until onion is softened. Stir in garlic and cook for 30 seconds to 1 minute.
Stir in flour and cook for 1 minute. Stir in broth, turkey, milk, and poultry seasoning. Taste and add salt and pepper to taste. Bring soup to a simmer.
In a medium bowl combine the flour, baking powder, poultry seasoning, salt, and pepper. Stir in the milk and egg just until combined and there isn't any dry flour.
Drop batter by 2 tablespoonfuls on top of the soup. Cover with a tight fitting lid and simmer for 15 minutes. Don't peek.
