Ingredients

  • 2 Tablespoons unsalted butter
  • 2 Tablespoons all purpose flour
  • ½ teaspoon salt
  • ½ teaspoon ground pepper
  • 4 cups chicken broth
  • 1 cup whole milk
  • 4 cups prepared mashed potatoes
  • ½ cup cheddar
  • Optional: Cheddar cheese, bacon, green onion/chives, sour cream for serving

Instructions

  • In a large pot, melt the butter over medium heat and add the flour, salt and pepper. Whisk ingredients together and cook for 1 minute.
  • Slowly pour the chicken broth into the pan, whisking constantly until smooth.
  • Then add the milk, mashed potatoes and cheddar cheese. Whisk together and cook for 5 minutes stirring constantly just until the soup reaches a simmer.
  • Continue cooking until desired thickness is reached.
  • Serve with optional toppings.

Notes

  • You can use any kind of leftover mashed potatoes – plain ones or ones that are flavored with cheese and other seasonings. You can also make a fresh batch of mashed potatoes, keep them in the fridge, and use them to make the soup.
  • Feel free to adjust the soup thickness by adding more mashed potatoes for a thicker soup or more broth for a thinner soup. It’s very flexible!
  • I like to keep things simple, but feel free to add other ingredients to your soup. You can sauté onions and garlic first to add more flavor or use different seasonings, dried herbs, or fresh herbs to change it up.
