Transform your leftover mashed potatoes into a delightful new dish with these mashed potato pancakes. Crispy on the outside and tender on the inside, these pancakes are perfect for breakfast, lunch, or even as a side dish. They are quick to make and a great way to reduce food waste while enjoying a delicious meal.
Most of the ingredients for this recipe are common pantry items. However, if you don't typically keep cheddar cheese or green onions on hand, you might need to pick these up at the supermarket. Cheddar cheese adds a rich, savory flavor, while green onions provide a fresh, slightly sharp taste that complements the mashed potatoes perfectly.

Ingredients For Leftover Mashed Potato Pancakes
Mashed potatoes: The base of the recipe, providing a creamy texture and rich flavor.
Cheddar cheese: Adds a savory, cheesy element that enhances the overall taste.
Egg: Acts as a binder to hold the pancakes together.
Flour: Helps to give structure and a slight crispiness to the pancakes.
Green onions: Adds a fresh, slightly sharp flavor that balances the richness of the potatoes and cheese.
Salt: Enhances the flavors of the other ingredients.
Pepper: Adds a touch of heat and depth to the flavor profile.
Oil: Used for frying the pancakes to achieve a golden, crispy exterior.
Pro Tip for Making Potato Pancakes
When forming the patties, make sure your hands are slightly damp. This prevents the mashed potato mixture from sticking to your hands and allows you to shape the patties more easily. Additionally, pressing the patties gently but firmly helps them hold together better during frying.

How to Store and Freeze Your Potato Pancakes
To store your leftover mashed potato pancakes, allow them to cool completely at room temperature. This prevents condensation, which can make them soggy.
Once cooled, place the pancakes in a single layer on a baking sheet lined with parchment paper. This step ensures they don't stick together.
Transfer the baking sheet to the refrigerator and let the pancakes chill for about 30 minutes. This helps them firm up before you store them.
After chilling, stack the pancakes with a piece of parchment paper between each one. This prevents them from sticking together and makes it easier to grab just one or two at a time.
Place the stacked pancakes in an airtight container or a resealable plastic bag. If using a plastic bag, try to remove as much air as possible before sealing.
Label the container or bag with the date so you can keep track of their freshness. Stored this way, the pancakes will stay good in the refrigerator for up to 3 days.
For longer storage, you can freeze the pancakes. Follow the same steps for cooling and chilling, then place the stacked pancakes in a freezer-safe container or bag.
When freezing, it's crucial to remove as much air as possible from the bag to prevent freezer burn. You can use a vacuum sealer if you have one, or simply press out the air manually.
Label the container or bag with the date and contents. Frozen mashed potato pancakes can be stored for up to 2 months.
To reheat, you can thaw the pancakes in the refrigerator overnight. Alternatively, you can reheat them directly from frozen by placing them in a preheated oven at 375°F (190°C) for about 10-15 minutes, or until heated through and crispy.
For a quicker option, you can also reheat them in a skillet over medium heat. Add a little oil to the pan and cook for 3-4 minutes on each side, or until heated through and crispy.
Serve your reheated potato pancakes with a dollop of sour cream or your favorite dipping sauce for a delicious and convenient meal.
