How to Make Mashed Potato Cakes

1. Combine mashed potatoes in a medium mixing bowl. Gently drizzle the whisked egg over the potatoes, then evenly sprinkle the flour, baking powder, garlic powder, onion powder, salt, and pepper to taste.

2. Stir the mixture with a fork until it comes together smoothly. If the mixture feels too loose, add a few more tablespoons of flour until it holds together nicely.

3. Scoop out the potato mixture using a 3 Tbsp cookie scoop, and drop each portion onto parchment paper or a greased cookie sheet, keeping them spaced apart.

4. Mix Panko bread crumbs and parmesan cheese in a shallow bowl, tossing them together to combine evenly and create the coating for your cakes.

5. Heat 1 1/2 Tbsp olive oil in a 12-inch non-stick skillet over medium heat until it shimmers, preparing for a perfect frying temperature.

6. Shape each portion of mashed potatoes into an even disk about 2 1/2 to 3 inches wide. Transfer to the Panko mixture, lightly pressing to coat each side thoroughly.

7. Cook six potato cakes at a time, frying for about 1 1/2 to 2 minutes per side until they become golden brown. Carefully flip them over to brown the other side.

8. Repeat the cooking process with the remaining potato mixture, adding another 1 1/2 Tbsp oil as needed to achieve that delicious golden hue on all cakes.

9. Serve warm and drizzle with sour cream, garnishing with fresh chives for a delightful finish to your flavorful Mashed Potato Cakes.

Optional: Add a sprinkle of smoked paprika on top before serving for an extra kick!

Expert Tips for Mashed Potato Cakes

• Chill Your Potatoes: Always use well-chilled leftover mashed potatoes for the best texture; warm potatoes can make the cakes too loose and hard to shape.
• Adjust Flour Gradually: If your mixture is too wet, add flour in small increments until the cakes hold their shape. Too much flour can make them gummy.
• Panko Magic: Using Panko bread crumbs ensures a crispier coating. If you can t find them, regular bread crumbs work, but may not be as crunchy as desired.
• Cook in Batches: Don t overcrowd the skillet; cook in batches for even browning and to prevent steaming, which keeps the cakes from getting crispy.
• Keep Them Warm: If making a larger batch, keep cooked cakes warm in a low oven while finishing the rest. This way, they all stay fresh and delicious for serving.
• Garnish Lovingly: Drizzle with sour cream and sprinkle with fresh chives before serving to add an extra layer of flavor to your Mashed Potato Cakes.

Mashed Potato Cakes Variations

Don t hesitate to get creative and personalize your Mashed Potato Cakes for a truly unique experience!

• Cheese-Lover s Delight: Add extra shredded cheese, such as cheddar or feta, to the potato mixture for a cheesy twist that melts beautifully.

• Spicy Kick: Mix in a teaspoon of chili powder or chopped jalape ±os for a delightful heat that wakes up your taste buds.

• Herbed Goodness: Incorporate finely chopped fresh herbs, like parsley or dill, into the batter for a burst of freshness with every bite.

• Veggie Boost: Fold in finely chopped cooked vegetables zucchini, spinach, or bell peppers for added nutrition and a vibrant splash of color.

• Gluten-Free Option: Substitute all-purpose flour with almond flour or a gluten-free flour blend to enjoy these cakes without the gluten.

• Vegan Version: Use a flaxseed meal and water mixture in place of the egg, plus nutritional yeast for that cheesy flavor while keeping it plant-based.

• Onion Lover s Bliss: Saut some finely chopped onions until caramelized, then mix them into the batter for savory sweetness that complements the creamy potatoes.

• Smoky Flavor: Add a dash of smoked paprika to the batter for a subtle, smoky flavor that pairs perfectly with the crispy exterior.
