Notes
Getting the Right Consistency
The secret to the perfect mashed potato patty is the right texture. The mixture should be thick enough to hold its shape, but not too dry or crumbly. Here’s what to look for:• Thick but workable. It should hold its shape when scooped but not be too firm.
• Slightly sticky. The batter should be just sticky enough to form patties without being too hard to handle.
• Not too wet. If the mixture is too runny, add more flour. If it’s too thick, a little milk or an extra egg can loosen it up.
Aim for a consistency similar to cookie dough—firm but easy to work with.
Recipe Tips
• Use a measuring cup to form even portions, ensuring uniform cooking.• Don’t overcrowd the pan—cook in a single layer for crispy cakes.
• Let the oil get hot before frying—when it shimmers, you’re ready to go.
• A little flour is key to binding the patties together perfectly.

Storing Leftover Potato Patties
Store leftovers in an airtight container in the fridge for 3-4 days. For best results, reheat in a skillet, oven, or air fryer.

Freezing the Crispy Potato Cakes
Freeze for later use by placing them in a freezer-safe bag with parchment paper between layers to prevent sticking.
Reheating. The best way to reheat frozen mashed potato patties is to ensure they stay crispy on the outside while heating through thoroughly. Here are a few methods to reheat them:
Oven (Best for Crispiness):
Preheat your oven to 375°F (190°C).
Place the frozen patties on a baking sheet in a single layer.
Bake for about 15-20 minutes, flipping halfway through, until they are golden and crispy on the outside. You can lightly brush them with oil for extra crispiness if needed.
Air Fryer (Quick and Crispy):
Preheat your air fryer to 375°F (190°C).
Arrange the frozen patties in a single layer in the air fryer basket.
Cook for 8-10 minutes, flipping halfway through, until the patties are heated through and crispy.
Skillet (For Crispiness and Quick Reheating):
Heat a non-stick skillet over medium heat and add a small amount of oil.
Place the frozen patties in the skillet in a single layer.
Cover the skillet with a lid and cook for about 5-7 minutes per side, turning carefully, until they are crispy and heated through.
Microwave (Quick but Less Crispy):
If you’re in a hurry, microwave the patties on a microwave-safe plate, covered with a damp paper towel, for about 1-2 minutes. However, the texture will be softer, and you won’t get the same crispy finish as with the other methods.
For the best results, the oven or air fryer method is ideal for retaining the crispiness of the patties while reheating them evenly.
These simple yet satisfying potato cakes are a great way to minimize food waste while enjoying a delicious snack or side dish, especially when you have a homestead full of hearty ingredients to work with. Enjoy them any time of day—savory or sweet—and watch them quickly become a family favorite!
