Transform Your Leftovers: The Ultimate Mashed Potato Cake Recipe

There’s something deeply comforting about mashed potatoes. I remember, as a child, sneaking into the kitchen after Thanksgiving dinner, armed with a spoon, to pilfer a cold scoop straight from the bowl. The creamy, slightly salty goodness was irresistible. But even the most ardent potato lover can find themselves with leftovers. Instead of letting them languish in the fridge, why not transform them into crispy, golden-brown mashed potato cakes? These humble patties are a testament to resourcefulness, turning yesterday’s side dish into today’s star.

Recipe Overview

Prep Time: 7 minutes
Cook Time: 15 minutes
Total Time: 22 minutes
Servings: 2
Dietary Type: Vegetarian

Ingredients

1 egg
1 cup mashed potatoes (leftover)
1/3 cup flour
1 green onion, finely chopped
1/2 teaspoon baking powder
1 teaspoon salt
1/4 teaspoon black pepper
1-2 tablespoons milk
2-3 tablespoons shortening or 2-3 tablespoons vegetable oil

Equipment Needed

Medium bowl
Mixing spoon or fork
Skillet or frying pan

Instructions

First, in a medium bowl, beat the egg until it’s light and frothy. This will help to bind the potato cakes together.
Next, add the mashed potatoes to the beaten egg and mix until well combined. Ensure there are no large clumps of potato remaining. This step is crucial for a consistent texture.
In the same bowl, stir in the flour, green onion, baking powder, salt, and black pepper. The baking powder will give the cakes a slightly lighter texture.
Now, gradually add the milk, one tablespoon at a time, and mix well. The batter should be very thick, almost like a drop biscuit dough. You might not need all the milk, so add it slowly until you reach the desired consistency.
In a skillet or frying pan, melt the shortening or heat the oil over medium heat. The pan is ready when a drop of water sizzles gently. Using shortening adds a richer flavor, but vegetable oil works just as well.
Spoon the batter into the skillet, forming pancakes that are about 3 to 3.5 inches wide and approximately 1/2 inch thick. Be careful not to overcrowd the pan; work in batches if necessary.
Brown the potato cakes on one side over medium heat for approximately 5-7 minutes, or until golden brown. The timing will vary depending on your stovetop.
Carefully turn the potato cakes and brown on the other side for another 5-7 minutes, or until they are heated through and golden brown.
Remove from the skillet and serve hot with your favorite condiments.

Expert Tips & Tricks

Don’t overmix the batter: Overmixing will develop the gluten in the flour, resulting in tough potato cakes. Mix just until the ingredients are combined.
Adjust the seasoning: Taste the batter before cooking and adjust the salt and pepper to your liking. You can also add other herbs and spices, such as garlic powder, onion powder, or paprika.
Control the heat: Cooking the potato cakes over medium heat ensures that they brown evenly without burning. If the cakes are browning too quickly, reduce the heat slightly.
Add cheese: For extra flavor and gooeyness, stir in shredded cheese (cheddar, mozzarella, or Gruyere) into the batter before cooking.
Crispy edges: For extra crispy edges, use a cast iron skillet. The cast iron distributes heat evenly and creates a beautiful sear.
Freezing: These are perfect for freezing! Let them cool completely, then freeze on a baking sheet lined with parchment paper. Once frozen solid, transfer to a freezer bag. Reheat in the oven or skillet until warmed through.

Serving & Storage Suggestions

Serve these delicious mashed potato cakes hot, straight from the skillet. They are fantastic with a dollop of ketchup, sour cream, or your favorite dipping sauce. They also make a great side dish for eggs, sausage, or bacon at breakfast.

Leftover potato cakes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, pan-fry them in a little oil until heated through and crispy. You can also reheat them in the oven at 350°F (175°C) for about 10-15 minutes.

While they can be left at room temperature for a short period (no more than 2 hours), refrigerating them is recommended to prevent bacterial growth.
