Make Your Leftover Mashed Potatoes into a Delicious and Easy Dinner with this Recipe.
Mashed Potatoes the Night Before
When I have leftover mashed potatoes, this quick dinner recipe is my go-to. Making extra mashed potatoes initially is handy for preparing this easy soup the following day. I prefer using white or yellow potatoes, though any variety works. I wash, peel, and cut the potatoes into uniform chunks, boiling them for about 25-30 minutes. Afterward, I strain them and add them into a mixing bowl. I add 1/4 cup of milk, 3-4 tablespoons of butter, 1/2 teaspoon of salt, 1/2 teaspoon of pepper, 1.5 teaspoons of garlic powder, and 1 tablespoon of dried green onions. Then, I blend everything into a creamy, slightly lumpy mixture. I typically use half a bag of potatoes to yield a large bowl of mashed potatoes.
Soup Time- So Easy and Yummy!
The following day, I take the leftover mashed potatoes and place them in a large pot, adding some milk. You can choose any type of milk you like, but I prefer using whole milk for my soup. I pour just enough milk to cover the potatoes with a bit extra. Refer to the photo below. With the stove set to medium heat, I season the mixture for enhanced flavor. I incorporate 1.5 teaspoons of garlic salt, a teaspoon of black pepper, a tablespoon of dried thyme, and 1.5 teaspoons of garlic powder. Once the seasonings are fully blended into the soup, I bring it to a boil and then reduce the heat to low, allowing it to simmer for about 10 minutes.
At this point, the soup is ready. I sprinkle dried green onion on top as a garnish. Grilled cheese sandwiches complement this soup perfectly. I melt butter in the pan, using butter bread and whatever cheese is available to make the sandwich.
