Step 1

Make the mashed potato mixture: In a big bowl, combine the mashed potatoes, feta, all-purpose flour, scallions, and parsley. Break the egg and add it to the bowl. Mix with a wooden spoon until everything is well incorporated.

Step 2

Prepare the breadcrumbs: Spread the breadcrumbs on a plate and set next to the bowl with the mashed potato mixture.

Step 3

Make the patties: Using a measuring cup (either a 1/4 cup or 1/3 cup, depending on the size of the patties you want), scoop a portion of the mashed potato mixture to fill the measuring cup. Form a ball between your hands, and then lightly flatten to make a 1/2-inch thick patty. Dredge the patty on both sides with the breadcrumbs and set it flat on a baking sheet. Repeat until the mashed potato mixture is finished.

Step 4

Fry the mashed potato patties: Set a large non-stick pan or skillet over medium-high heat. Add enough olive oil to the pan so it's about 1/2-inch deep. When the oil shimmers, arrange the patties in the pan in one single layer (do this in batches, if needed). Cook on one side for about 2 to 3 minutes or until the bottom is crispy and golden brown, then turn over and cook the patties for another 2 to 3 minutes, again watching for the crisp and color on the other side.

Step 5

Using the spatula, remove the cooked mashed potato patties from the skillet and transfer them to a tray, lined with a paper towel to drain any excess oil.

Step 6

Transfer the mashed potato patties to a serving plate and garnish with a bit more feta cheese and scallions. Enjoy!
