These old fashioned potato cakes are a delightful way to use up leftover mashed potatoes. Crispy on the outside and tender on the inside, they make for a perfect side dish or a light meal. The addition of green onions adds a fresh, savory note that complements the creamy potatoes beautifully.
Most of the ingredients for this recipe are common pantry staples. However, you might need to pick up green onions if you don't usually keep them on hand. These add a nice crunch and a mild onion flavor to the potato cakes. Everything else, like mashed potatoes, egg, flour, and vegetable oil, are typically found in most kitchens.
Ingredients For Old Fashioned Potato Cakes
Mashed potatoes: These form the base of the potato cakes, providing a creamy texture and rich flavor.
Egg: Acts as a binder to hold the potato mixture together.
Flour: Helps to give structure to the potato cakes and ensures they hold their shape while cooking.
Green onions: Adds a fresh, savory flavor and a bit of crunch to the potato cakes.
Vegetable oil: Used for frying the potato cakes, giving them a crispy, golden exterior.
Technique Tip for Potato Cakes
To achieve a crispier texture for your potato cakes, ensure the mashed potatoes are well-chilled before mixing with the other ingredients. This helps the mixture hold together better during frying. Additionally, avoid overcrowding the skillet to maintain an even cooking temperature, allowing each cake to brown perfectly.

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 layers 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 freezing, arrange the potato cakes in a single layer on a baking sheet lined with parchment paper. Freeze until solid, about 1-2 hours.
- Transfer the frozen potato cakes to a freezer-safe bag or container, separating layers with parchment paper. Label with the date.
- Freeze for up to 2 months. To reheat, bake directly from frozen at 375°F for 15-20 minutes, or until heated through and crispy.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Arrange 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.
Heat a non-stick skillet over medium heat. Add a small amount of vegetable oil or butter. Place the potato cakes in the skillet and cook for 2-3 minutes on each side until they are warmed through and regain their golden-brown crust.
Use a microwave-safe plate and cover the potato cakes with a damp paper towel. Microwave on medium power for 1-2 minutes, checking halfway to ensure they are evenly heated. Note that this method may not retain the crispiness as well as other methods.
For a quick reheat, use a toaster oven. Set it to 350°F (175°C) and place the potato cakes directly on the rack or on a baking sheet. Toast for 5-7 minutes until they are hot and crispy.
If you have an air fryer, preheat it to 350°F (175°C). Place the potato cakes in a single layer in the basket. Air fry for 5-6 minutes, shaking the basket halfway through, until they are heated through and crispy.
