Servings: 6 servings
Calories: 300kcal
INGREDIENTS
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 5 cups vegetable broth
- 2 ½ cups whole milk
- 3 cups leftover mashed potatoes
- ½ cup shredded cheddar cheese
- 1 teaspoon kosher salt or more to taste
- ½ teaspoon black pepper or more to taste
Toppings
- sour cream, shredded cheddar cheese, smoked turkey, sliced green onion
INSTRUCTIONS
- Add the flour to a large pot with melted butter over medium heat. Mix well. To eliminate any raw flour taste, cook for a further 30 to 60 seconds.
- Add the milk to the pot and stir for a minute, whisking continuously.
- Slowly pour the vegetable broth into the pot, whisking continuously until smooth.
- Next, add the cheddar cheese and mashed potatoes, stirring until the cheese has melted and the potatoes are fully incorporated. Add salt and pepper to taste and simmer until thoroughly warm.
- Remove from heat, ladle into bowls, and serve. Add smoked turkey, sour cream, chopped green onions or chives, and shredded cheddar cheese on top.
NOTES
- Gluten Free: Make the roux with gluten-free flour.
- Add more broth to thin out the soup and boil it longer for a thicker soup.
- Take care not to let the flour butter paste cook for more than the extra 30 to 60 seconds that are specified. Throughout this time, stir it frequently to avoid burning or browning.
- Any type of leftover mashed potatoes will work, including those that have been seasoned with cheese and other ingredients. Another option is to prepare a batch of mashed potatoes ahead of time, store them in the refrigerator, and then use them to make the soup.
- Do you want to turn this soup into a vegetarian one? It already uses vegetable broth, so just omit the smoked turkey garnish.
