This Leftover Turkey Soup is a fantastic way to use up leftover turkey (both meat and the bones!) from a roast turkey. It’s such a delicious soup that is ideal to keep in your freezer for those times you are looking for a quick and comforting meal. This Turkey Soup is Paleo, Whole30, Grain Free, Gluten Free, Dairy Free and Specific Carbohydrate Diet Legal. 

This is a grain free spin on a soup that my Mom used to make a few days after Thanksgiving each year. After a few days of turkey sandwiches for both lunch and dinner, we would finally hit our leftover turkey limit, and my Mom would whip up a batch of this soup with the remainder. This soup has a base of turkey stock made using the bones and carcass of the bird, and is packed with chunks of both white and dark meat, cubes of carrot, onion, celery, garlic, herbs and cauliflower rice which helps to bulk it up. This soup freezes well, so if you have hit your post Thanksgiving turkey quota, you can freeze it in batches for later.  


Why you are going to love this Leftover Turkey Soup:

  1. It’s the perfect way to use up leftover turkey: I love that this soup uses up absolutely all of the leftover turkey, including the carcass! 
  2. It’s easy to make: Although it takes some time for the bones to simmer and create a rich broth, once you have the broth, the rest of the soup takes just minutes to make. 
  3. It’s comfort in a bowl: this soup is so dang comforting! It’s perfect for a cold winter’s day, or when you are feeling under the weather. 
  4. So healthy: turkey stock (like other bone broths) is highly nutritious. It contains collagen which is good for everything from gut health and joints, to your skin, nails and hair. The stock also helps to reduce inflammation and is high in calcium, magnesium and vitamins a and k. 

Tips for making this Turkey Soup:

  1. Cut down the cook time: rather than make the turkey stock from scratch using leftover carcass, you can use store bought turkey stock or even chicken stock.
  2. Make the stock in a slow cooker: The key to the best stock is cooking the turkey bones for a long time to get out all of the nutrients and flavour. While simmering it on the stove top is quicker, I find a slow cooker to be the easiest and most hassle free option. Put all of the bones in the slow cooker with water and seasoning after dinner, and wake up in the morning to a rich and flavourful turkey stock. 
  3. Make it oil free: although this soup is already very healthy, you can skip the oil entirely by sauteing the onion and garlic in one tablespoon of chicken or turkey stock. The stock will soften the veggies while also infusing extra flavour. This is a great tip to use any time you need to saute vegetables. 


Ways to modify this leftover turkey soup:

  • Use chicken: This soup works just as well using leftover chicken. If you have a whole roasted chicken you can use the carcass to make the stock. Chop the cooked meat up and add it into the soup in place of turkey. 
  • Not on a grain free diet? To keep this soup Whole30, Paleo and Grain Free I use cauliflower rice which I love adding to soup because it adds substance without leaving you with that heavy feeling after eating it. Alternatively for anyone not following a grain free diet, rice, pasta or quinoa would be a great way to bulk up the soup. I would recommend cooking the rice or quinoa before adding it to the soup, while the pasta can be cooked in the soup.
  • Add in other veggies: Carrots, onion and celery are my go to trio of vegetables for soup, but there are many other veggies you could add in. Options include thinly sliced fennel, shaved brussels sprouts, mushrooms or cubed butternut squash. 
  • Make it keto: skip the carrots to make this soup low carb and keto

How to store this Turkey Soup 

  1. In the fridge: Store in an airtight container in the fridge for up to 5 days. The soup can be reheated in the microwave or in a pot on the stove top.
  2. In the freezer: This soup freezes really well and will last for up to 4 months in the freezer. You can freeze the soup before adding in the cauliflower rice  and then add it in after thawing out the soup, this prevent the cauliflower rice from becoming overcooked and mushy in the cook, thaw and reheat process. Alternatively if you plan on making this soup to freeze, I would recommend slightly undercooking the cauliflower rice by a minute or two.

Servings 6


Turkey Stock

  • leftover turkey carcass
  • 10 cups water
  • 1 tbsp lemon juice


  • 1 tsp olive oil
  • 3 cloves garlic minced
  • 1 onion finely diced
  • 1/2 tsp salt
  • 3 stalks celery (1 1/2 cups diced)
  • 2 large carrots (1 1/2 cups diced)
  • 6 cups turkey stock
  • 2 bay leaves
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 tsp poultry seasoning
  • 3 cups diced leftover cooked turkey meat
  • 2 cups cauliflower rice


Turkey Stock

  • Place the turkey carcass into a large pot with water and lemon juice. Bring to a gentle simmer and lower the heat low. Leave to gently simmer for 3 hours. Alternatively you can put everything into a slow cooker and leave it to cook on low heat for 8 hours.
  • Pour the turkey broth through a colander into a large bowl to remove the bones so you are left with just the stock (you should have approximately 6-7 cups). Set the stock aside while you prep the rest of the soup.


  • Heat the olive oil in the pot on medium heat and add in the onion and garlic and sprinkle with salt. Saute for 2 minutes before adding in the carrot and celery and cook for 8 minutes.
  • Pour the turkey stock into the soup and add in the bay leaves, poultry seasoning, salt and pepper and leave to simmer for 10 minutes before adding in the diced turkey meat and cauliflower rice.
  • Leave the soup to simmer for 4-5 more minutes until the cauliflower rice is tender. Divide the soup between 6 bowls and garnish with chopped parsley before serving.
