In a large stockpot or Dutch-oven set over medium-high heat, add 2 tablespoons extra virgin olive oil and diced onion with a pinch of salt and pepper. Sauté for 4-5 minutes, then add in 2 ribs of chopped celery and 2 chopped carrots with another pinch of salt and pepper. Continue cooking, stirring occasionally, for another 6-8 minutes until the vegetables are slightly softened and the onions are a bit translucent but not browning.
Now add in 2-3 cloves of minced garlic and thyme leaves and continue stirring and sautéing another 1-2 minutes. Pour in 8 cups of turkey stock and bring it to a boil. Once boiling, cover and lower to a simmer. Allow the soup to simmer, stirring occasionally, until the flavors can meld and the vegetables finish softening, about 15-20 minutes.
While the soup is simmering, make the dumplings. In a mixing bowl, whisk 2 large eggs and then add in ½ teaspoon salt, ¼ teaspoon ground black pepper, and ⅓ cup all-purpose flour. Stir everything together and then add in 2 cups of leftover stuffing. Gently fold everything together or go in with your hands and make sure everything is thoroughly combined without overworking the mixture.
Before adding the dumplings, give the soup a quick taste and add more salt and pepper if needed.
Turn the heat back up to medium for a stronger simmer on the soup. Using a 1-1 ½ tablespoon cookie scoop, scoop out balls of the stuffing dumplings and drop into the soup. Alternatively, grab some stuffing with your hands and roll into shaggy balls slightly smaller than golf balls. Cover the soup again and cook another 3-4 minutes at a strong simmer until the dumplings are floating and no longer eggy.
Remove the cover and stir in 2cups of chopped or shredded turkey and roughly 1 tablespoon of finely chopped flat-leaf parsley, flipping the dumplings over. Lower the heat to a simmer again and continue cooking for another 5 minutes, until the turkey is heated through.
Ladle into bowls and serve hot. Top with additional fresh thyme or parsley if desired.
1) Turkey – Pretty much any leftover turkey should be fine here, from fried, smoked, to oven roasted. I used a mix of white and dark meat from my herb-roasted turkey here for reference.2) Stuffing – I used leftover sausage and sage stuffing in this recipe, but most stuffings and dressings should work. Using a sausage stuffing gives an added meat to contrast the turkey, which I like, but use what you have. Don’t use rice dressing and I wouldn’t recommend seafood types of stuffing or dressing either. If you try it with one and love it, please let me know in the comments.3) Turkey Stock – While I love this soup with my homemade turkey stock, if you don’t have that, it’s fine. Use a store-bought low-sodium turkey (if you can find one) or chicken stock instead, or vegetable broth. If you saved the turkey carcass and any bones, you could throw together a quick turkey stock before making this soup though.4) No Stuffing – If you don’t have leftover stuffing or the right kind for this recipe, you have two options. You can grab a small box or bag of stovetop type stuffing and make that the day before, or you can make regular drop dumplings.This isn’t a specific recipe, but a basic dumpling recipe is like 1 cup flour, 2 teaspoons baking powder, ½ teaspoon salt, ½ teaspoon black pepper, ½ cup milk, and optionally 2 tablespoons of butter or lard. Mix it together, let it rest 10-15 minutes, then spoon roughly 1 tablespoon dumplings to the soup while it is at a low boil. Cover and cook them for about 12-15 minutes.5) Nutrition Info – The nutritional info provided here is a best guess average. Depending on the ingredients you use (especially the turkey and stuffing) and how large a bowl you eat will greatly affect the values.
