These old fashioned potato cakes are a delightful way to use up leftover mashed potatoes. Crispy on the outside and soft on the inside, they make a perfect side dish or even a light meal. The addition of green onions adds a fresh, savory note that complements the potatoes beautifully.
Most of the ingredients for this recipe are common pantry staples. However, if you don't usually keep green onions on hand, you might need to pick some up at the supermarket. They add a nice crunch and a mild onion flavor that enhances the overall taste of the potato cakes.

Ingredients For Old Fashioned Potato Cakes
Mashed potatoes: These form the base of the cakes, providing a creamy texture.
Beaten egg: Acts as a binder to hold the cakes together.
Flour: Helps to give structure and a slight crispiness to the cakes.
Chopped green onions: Adds a fresh, savory flavor and a bit of crunch.
Salt: Enhances the overall flavor of the cakes.
Black pepper: Adds a touch of heat and depth to the flavor.
Vegetable oil: Used for frying the cakes to a golden brown.
Technique Tip for Perfect Potato Cakes
When forming the potato cakes, make sure your mashed potatoes are not too wet. If they are, the cakes may fall apart during frying. To achieve the best texture, let the mashed potatoes cool completely before mixing with the other ingredients. This helps the flour and egg bind the mixture better, resulting in crispy and well-formed potato cakes.

How to Store or Freeze Potato Cakes
Allow the potato cakes to cool completely before storing. This prevents condensation, which can make them soggy.
Place the cooled potato cakes in an airtight container. If stacking, separate each layer with parchment paper to avoid sticking.
Store the container in the refrigerator for up to 3-4 days. Reheat in a skillet over medium heat or in the oven at 350°F until warmed through.
For longer storage, freeze the potato cakes. Lay them out on a baking sheet in a single layer and freeze until solid, about 1-2 hours.
Once frozen, transfer the potato cakes to a freezer-safe bag or container. Label with the date and use within 2-3 months for best quality.
To reheat from frozen, bake in a preheated oven at 375°F for 15-20 minutes, or until heated through and crispy. Alternatively, reheat in a skillet over medium-low heat, flipping occasionally, until warmed through.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the potato cakes on a baking sheet lined with parchment paper. Bake for 10-15 minutes, flipping halfway through, until they are heated through and crispy on the outside.
Stovetop Method: Heat a non-stick skillet over medium heat and add a small amount of vegetable oil. Place the potato cakes in the skillet and cook for 2-3 minutes on each side, or until they are warmed through and have regained their crispy exterior.
Microwave Method: Place the potato cakes on a microwave-safe plate. Cover them with a damp paper towel to prevent drying out. Microwave on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated. Note that this method may not retain the crispiness as well as the other methods.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the potato cakes in a single layer in the air fryer basket. Cook for 5-7 minutes, flipping halfway through, until they are heated through and crispy.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the potato cakes on the toaster oven tray. Heat for 10-12 minutes, flipping halfway through, until they are hot and crispy.
Essential Tools for Making Potato Cakes
Mixing bowl: A large bowl to combine and mix all the ingredients together.
Frying pan: A flat-bottomed pan to fry the potato cakes until they are golden brown and crispy.

Time-Saving Tips for Potato Cakes
Prepare ingredients ahead: Measure and chop green onions and beat the egg in advance to streamline the process.
Use leftover mashed potatoes: Save time by using leftover mashed potatoes from a previous meal.
Preheat the pan: Start heating the vegetable oil while mixing the ingredients to save time.
Batch cooking: Shape all potato cakes before frying, so you can cook them in quick succession.
Uniform shape: Use a measuring cup to ensure each potato patty is the same size for even cooking.
