Step‑by‑Step Instructions for Fried Mashed Potato Cakes
Step 1: Mix Ingredients
In a large mixing bowl, combine your cold, leftover mashed potatoes with one large egg. Use a fork to blend them until the mixture is smooth and homogenous, ensuring the egg is fully incorporated. This process should take about 2 minutes. The consistency should be creamy yet thick, ready to form patties.
Step 2: Add Remaining Ingredients
Next, gently fold in the grated yellow onion, all-purpose flour, kosher salt, and black pepper into the mixture. Use your fork to mix these ingredients together, taking care not to overwork the batter as this could lead to gummy patties. Aim for an even distribution of the onion and seasonings, which should take another 2 minutes.
Step 3: Heat Oil
Pour about ½ inch of canola oil into a large frying pan and heat it over medium heat until it reaches 350°F. You can check the temperature with a kitchen thermometer or by dropping a small spoonful of the batter into the oil; it should sizzle immediately. This step is crucial for achieving perfectly crispy Fried Mashed Potato Cakes.
Step 4: Form Patties
Once the oil is hot, scoop approximately ½ cup of the potato mixture and shape it gently into a patty about ½ inch thick. Carefully drop the patty into the hot oil, ensuring not to overcrowd the pan. Depending on your pan size, you can fry 3-4 patties at a time without compromising the temperature.
Step 5: Fry
Fry each patty for 2.5 to 3 minutes until they turn a beautiful golden brown. Use a spatula to flip them carefully halfway through cooking to ensure even browning on both sides. Once done, transfer the patties to a cooling rack lined with paper towels to absorb any excess oil while maintaining their crispy texture.
Step 6: Serve Immediately
Enjoy your warm Fried Mashed Potato Cakes right away for the best flavor experience. Pair them with your favorite toppings like sour cream or fresh chives, or serve them alongside a sunny-side-up egg for breakfast. The contrast of crispy outside and fluffy inside makes every bite utterly delicious!
Make Ahead Options
These Fried Mashed Potato Cakes are perfect for those busy weeknights when you need to save time! You can prepare the potato mixture up to 24 hours ahead of time: mix the cold mashed potatoes, egg, onion, flour, salt, and pepper, then refrigerate it in an airtight container. This will not only save you time but also enhance the flavors as they meld together. When you’re ready to serve, simply heat the oil and form the patties right before frying for that crispy texture you crave. It’s a simple way to enjoy these comforting cakes just as deliciously as if you made them fresh!
