Transform your leftover mashed potatoes into a delightful breakfast or snack with these savory pancakes. They are crispy on the outside, soft on the inside, and packed with flavor. This recipe is a great way to reduce food waste while enjoying a delicious dish.
If you don't usually have green onions or grated cheese in your kitchen, you might need to pick these up at the supermarket. Green onions add a fresh, mild onion flavor, while grated cheese brings a rich, savory taste to the pancakes.

Ingredients for Leftover Mashed Potato Pancakes
Mashed potatoes: These are the base of your pancakes, providing a creamy texture and rich flavor.
Egg: Acts as a binder to hold the pancake mixture together.
Flour: Helps to give structure to the pancakes, making them easier to flip and cook.
Grated cheese: Adds a savory, cheesy flavor to the pancakes.
Green onions: Provide a fresh, mild onion taste that complements the other ingredients.
Vegetable oil: Used for frying the pancakes to achieve a crispy, golden-brown exterior.
Technique Tip for Making Potato Pancakes
When mixing the mashed potatoes with the egg, flour, cheese, and green onions, ensure the mixture is well-combined but not overworked. Overmixing can make the pancakes dense rather than light and fluffy. Use a gentle folding motion to incorporate the ingredients evenly.

How to Store or Freeze Your Potato Pancakes
Allow the leftover mashed potato pancakes to cool completely before storing. This prevents condensation, which can make them soggy.
Place the cooled 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 freezer and let the pancakes freeze for about 1-2 hours. This initial freezing step, known as flash freezing, helps maintain their shape and texture.
Once frozen, remove the pancakes from the baking sheet and place them in a freezer-safe bag or airtight container. Be sure to label the container with the date for easy reference.
For added protection against freezer burn, consider wrapping each pancake individually in plastic wrap or aluminum foil before placing them in the container.
When ready to enjoy, reheat the pancakes directly from the freezer. Preheat your oven to 375°F (190°C) and place the frozen pancakes on a baking sheet. Bake for 10-15 minutes, or until heated through and crispy.
Alternatively, you can reheat them in a skillet. Heat a small amount of vegetable oil over medium heat and cook the frozen pancakes for 3-4 minutes on each side, or until golden brown and heated through.
If storing in the refrigerator, place the cooled pancakes in an airtight container. They will keep for up to 3 days. Reheat them in a skillet or oven as described above.
To maintain the best texture and flavor, avoid microwaving the pancakes, as this can make them rubbery and less appetizing.
How to Reheat Leftover Pancakes
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover mashed potato pancakes on a baking sheet lined with parchment paper. Cover them with aluminum foil to prevent drying out. Bake for about 10-15 minutes or until heated through. This method helps maintain their crispy exterior.
Stovetop Method: Heat a non-stick skillet over medium heat and add a small amount of vegetable oil. Place the pancakes in the skillet and cook for 2-3 minutes on each side, or until they are heated through and crispy again. This method is quick and keeps the pancakes crispy.
Microwave Method: Place the pancakes on a microwave-safe plate. Cover them with a damp paper towel to keep them moist. Microwave on medium power for 1-2 minutes, checking halfway through. This method is the fastest but may result in a softer texture.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the pancakes in a single layer in the air fryer basket. Cook for 3-5 minutes, flipping halfway through, until they are heated through and crispy. This method combines speed and crispiness.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the pancakes on the toaster oven tray. Heat for about 10 minutes, or until they are warmed through and crispy. This method is convenient for small batches.
