How to Make Slow Cooker Thanksgiving leftover Soup

Thanksgiving leftovers are practically a given for many of us. This leftover soup is a great way to put them back on the table before they go bad in your fridge. And a slow cooker takes all the work out of it, so you don’t have to do all that Thanksgiving prep work all over again. 

To start this soup, simply shred your turkey and add it to the slow cooker. Add mashed potatoes, gravy, and any veggies you cooked for your feast, like carrots or green beans. Next, add chicken broth to pull it all together. A few hours in the slow cooker turns your Thanksgiving leftovers into a delicious slow cooker soup! 

Tips To Prepare

– Prep Ingredients: Chopping veggies and turkey into bite-sized pieces. 

– Sauté Onions and Garlic: For a richer flavor, you can sauté the onions and garlic in a little oil or butter before adding them to the slow cooker. This step is optional but can enhance the overall taste.

– Layer Ingredients: Layer your ingredients in the slow cooker. Start with the turkey and then add the mashed potatoes, vegetables, herbs, and seasonings. Pour the broth or water over everything.

– Cooking Time: Set slow cooker to low and cook for 6-8 hours, or on high for 3-4 hours. Cooking times can vary depending on specific slow cooker, so check it every now and then.

– Skim the Broth: Skim off any impurities that rise to the surface during cooking. This helps make your broth clearer and cleaner in taste.

– Taste and Adjust: About an hour before serving, taste the soup and adjust the seasoning if necessary by adding more salt, pepper, or herbs.

– Serve: Ladle the hot soup into bowls and enjoy with some crusty bread on the side.

– Variations: You can customize your turkey soup by adding other ingredients like beans, corn, or greens like spinach. Get creative with what you have on hand.

Remember, slow cooking allows the flavors to blend together beautifully, creating a rich and comforting soup.
