Transforming Leftover Mashed Potatoes into Delicious Masterpieces

Leftover mashed potatoes are a common occurrence after a big family dinner or holiday feast. Instead of letting them go to waste, why not get creative and turn those extras into something extraordinary? With a little ingenuity and a few simple ingredients, you can transform your leftover mashed potatoes into sensational dishes that will make your taste buds dance with delight. Here are a few ideas to get you started:

1. Mashed Potato Pancakes:

Leftover mashed potatoes can serve as the perfect base for deliciously crispy pancakes. Simply mix in some finely chopped onions, an egg, and a sprinkle of flour to bind the mixture together. Shape the mixture into patties and gently fry them in a pan until golden brown on each side. Serve with a dollop of sour cream or your favorite sauce for a delightful twist on traditional pancakes.

2. Loaded Mashed Potato Casserole:

Take your leftover mashed potatoes to the next level by creating a hearty casserole. Spread the mashed potatoes in a baking dish and top with crispy bacon, shredded cheese, and chopped green onions. Bake in the oven until the cheese is melted and bubbly. This gooey and savory dish is sure to be a hit at any gathering.

3. Mashed Potato Croquettes:

Transform your mashed potatoes into mouthwatering croquettes by rolling them into small balls and coating them in breadcrumbs. Deep fry or bake the croquettes until golden and crispy. These little bites of heaven can be served as an appetizer or as a side dish for your next meal.

4. Shepherd’s Pie:

Leftover mashed potatoes are the perfect topping for a scrumptious shepherd’s pie. Sauté ground meat (such as turkey, beef, or lamb) with diced onions, carrots, and peas. Season with your favorite herbs and spices, then spread the mixture in a baking dish. Top with a generous layer of mashed potatoes and bake until the potatoes are golden and the filling is bubbling. This comforting dish will warm both your heart and stomach on chilly nights.

5. Mashed Potato Soup:

Turn your leftover mashed potatoes into a creamy and comforting soup. Simply combine the mashed potatoes with chicken or vegetable broth, diced vegetables, and your favorite seasonings. Heat the mixture until it simmers, then blend until smooth. Adjust the consistency with additional broth, if necessary. Garnish with grated cheese, chives, or crumbled bacon for an extra touch of flavor.


Leftover mashed potatoes no longer have to be a mundane side dish. With a little creativity, you can transform them into extraordinary meals that will impress your family and friends. Whether you opt for savory pancakes, loaded casseroles, crispy croquettes, flavorful shepherd’s pie, or creamy soup, you can’t go wrong with these delicious creations.

What are some creative ways to use leftover mashed potatoes?
Leftover mashed potatoes can be used in several delicious ways. You can make potato pancakes by mixing the mashed potatoes with flour, eggs, and seasonings and then frying them until golden brown. Another option is to make shepherd’s pie by layering mashed potatoes on top of a meat and vegetable filling, and then baking until the potatoes are crispy. Additionally, you can mix mashed potatoes with grated cheese and herbs to make flavorful potato croquettes or use them as a creamy topping for casseroles.
How can I reheat leftover mashed potatoes without drying them out?
To reheat mashed potatoes without drying them out, it’s best to use gentle heat. Place them in a saucepan over low heat and stir constantly until heated through. Adding a splash of milk or butter while reheating can also help to restore some of the moisture. Another option is to heat them in the microwave in short bursts, stirring in between, to ensure even heating.
Can leftover mashed potatoes be frozen for later use?
Yes, mashed potatoes can be frozen for later use. Transfer them to an airtight container or freezer bag and label it with the date. When you’re ready to use them, thaw them in the refrigerator overnight and then reheat them using your preferred method. Keep in mind that the texture might change slightly after freezing, so they might be slightly less creamy than when freshly made.
What can I do with leftover mashed potatoes if I don’t want to reheat them?
If you’re not in the mood to reheat leftover mashed potatoes, you can repurpose them in other dishes. Try using them as a binder for meatballs or meatloaf, adding them to soups or stews as a thickener, or even using them as a filling for pierogies. You can also mix them with eggs and vegetables to make a satisfying potato and vegetable frittata.
Are there any vegan options for using leftover mashed potatoes?
Absolutely! Vegan options for using leftover mashed potatoes include making vegan shepherd’s pie by substituting the meat with lentils or beans, and using plant-based butter and milk to keep the mashed potatoes creamy. You can also use the mashed potatoes as a base for vegan potato soup by adding vegetable broth, diced vegetables, and herbs. Another delicious option is to make vegan potato pancakes by replacing the eggs with a flaxseed or chia seed mixture.
Can I use leftover mashed sweet potatoes in the same way as regular mashed potatoes?
Yes, you can definitely use leftover mashed sweet potatoes in similar ways to regular mashed potatoes. They can be used to make sweet potato pancakes, added to casseroles, or used as a topping for shepherd’s pie. Alternatively, you can use them to make sweet treats such as sweet potato muffins or sweet potato bread. The natural sweetness of the sweet potatoes adds a unique flavor to these dishes.
