Ingredients
Soup Base
- 2 tablespoons butter
- ½ small onion, diced
- 1 tablespoon all-purpose flour
- 2 cups vegetable or chicken stock
- 1 teaspoon Italian seasoning
Main Ingredients
- 3 cups leftover mashed potatoes
- 1/3 cup Parmesan cheese, freshly grated
- Salt and pepper (to taste)
Toppings (Optional)
- Cheddar cheese, shredded
Instructions
- Prepare the base: In a large stockpot, melt butter over medium-high heat until it starts to bubble, about 1 minute. Add the diced onion and sauté until the onion is soft, tender, and beginning to brown, approximately 3-4 minutes.
- Create the roux and add seasoning: Sprinkle in the flour and stir well to combine with the onion mixture. Cook this mixture for another minute to remove the raw flour taste. Pour in the vegetable or chicken stock and add Italian seasoning, stirring thoroughly. Bring the mixture to a simmer over medium heat, which should take around 3-4 minutes.
- Incorporate mashed potatoes and cheese: Add the leftover mashed potatoes and freshly grated Parmesan cheese to the pot. Stir continuously until the mashed potatoes break up completely and the cheese melts into the soup. Season with salt and pepper to your preference. Allow the soup to simmer gently for 8-10 minutes, stirring occasionally, until it reaches your desired thickness.
- Serve and garnish: Ladle the hot soup into bowls and top each serving with shredded cheddar cheese if desired. Serve immediately for the best flavor and texture.
Notes
- Leftover mashed potatoes can be used straight from the fridge; no need to warm them up first.
- For a richer soup, substitute butter with olive oil or add a splash of cream before serving.
- Feel free to add cooked bacon bits or chopped chives as additional toppings.
- If the soup is too thick, thin it out with a little more stock or water while simmering.
- This recipe is easily adaptable to a vegetarian diet by using vegetable stock.
